BPMN 2.0 Introduction to the Standard for Business Process Modeling By Thomas Allweyer2.1 A First BPMN ModelAs a starting point, a simple BPMN process model is considered. The model of posting a job in figure 1 can be directly understood by most people who previously have been concerned with any kind of process modeling. The way of modeling is similar to well known flow charts and activity diagrams.Figure 1: A simple BPMN modelA business department and the human resources department are involved in the process “Post a Job”. The process starts when an employee is required. The business department reports this job opening. Then the human resources department writes a job posting. The business department reviews this job posting.At this point, there are two possibilities: Either the job posting is okay, or it is not okay. If it is not okay, it is reworked by the human resources department. This is once more followed by the business department reviewing the job posting. Again, the result can be okay or not okay. Thus, it can happen that the job posting needs to be reviewed multiple times. If it is okay, it is published by the human resources department, and the end of the process is reached.In reality, the process for creating and publishing a job posting can be much more complex and extensive. The presented example is –like all examples in this book –a simplification in order to have small and easily understandable models which can be used for explaining the different BPMN elements.2.2 BPMN Constructs UsedBelow each element from the model in figure 1 is explained more closely. The entire process is contained in a pool. This is a general kind of container for a complete process. In the example above, the pool is labeled with the name of the contained process.Every process is situated within a pool. If the pool is not important for understanding the process, it is not required to draw it in the diagram. In a process diagram which does not show a pool, the entire process is contained in an invisible, implicit pool. Pools are especially interesting when several pools are used in order to model a collaboration, i.e. the interplay of several partners’processes. Each partner’s process is then shown in a separate pool. This will be described in chapter 5.The pool from figure 1 is partitioned into two lanes. A lane can be used for various purposes,e.g. for assigning organizational units, as in the example, or for representing different components within a technical system. In the example, the lanes show witch of the process’s activities are performed by the business department and which by the human resource department.Pools and lanes are also called “swimlanes”. They resemble the partitioning of swimming pools into lanes. Every participant of a competition swims only in his own lane.The process itself begins with the start event “Employee required”. Processes usually have such a start event. Its symbol is a simple circle. In most cases it makes sense to use only one start event, not several ones.A rounded rectangle represents an activity. In an activity something gets done. This is expressed by the activities’names, such as “Report Job Opening”or “Review Job Posting”.The connecting arrows are used for modeling the sequence flow. They represent the sequence in which the different events, activities, and further elements are traversed. Often this is called control flow, but in BPMN there is a second type of flow, the message flow, which influences the control of a process as well, and is therefore some kind of control flow, too. For that reason, the term “sequence flow”is used. For distinguishing it from other kinds of flow, it is important to draw sequence flows with solid lines and filled arrowheads.The process “Post a Job”contains a split: The activity “Review job posting”is followed by a gateway. A blank diamond shape stands for an exclusive gateway. This means that out of several outgoing sequence flows, exactly one must be selected. Every time the right gateway in the job posting-process is reached, a decision must be taken. Either the sequence flow to the right is followed, leading to the activity “Publish Job Posting”, or the one to the left is selected, triggering the activity “Rework Job Posting”. It is not possible to follow both paths simultaneously.The logic of such a decision is also called “exclusive OR”, abbreviated “XOR”. The conditions on the outgoing paths determine which path is selected. If a modeling tool is used and the process has to be executed or simulated by a software program, then it is usually possible to formally define exact conditions. Such formal descriptions, which may be expressed in a programming language, can be stored in special attributes of the sequence flows.If, on the other hand, the purpose of a model is to explain a process to other people,then it is advisable to write informal, but understandable, statements directly into the diagram, next to the sequence flows. The meaning of “okay”and “not okay”after the activity called “Review Job Posting”is clear to humans –a program could not make use of it.Gateways are also used for merging alternative paths. In the sample process, the gateway on the left of the activity “Review Job Posting”merges the two incoming sequence flows. Again, this is an exclusive gateway. It expects that either the activity“Write Job Posting”or “Rework Job Posting”is carried out before the gateway is reached –but not both at the same time. It should be taken care to use a gateway either for splitting or for joining, but not for a combination of both. The last element in the example process is the end event. Like the start event it has a circle as symbol –but with a thick border.2.3 Sequence Flow LogicThe flow logic of the job posting process above is rather easy to understand. In more complex models it is sometimes not clear how the modeled structure exactly is to be interpreted. Therefore it is helpful if the meaning of the sequence flow’s elements is defined in an unambiguous way.The logic of a process diagram’s sequence flow can be explained by “tokens”. Just as in a board game tokens are moved over the board according to the game’s rules, one can imagine moving tokens through a process model according to BPMN’s rules.Every time the process is started, the start event creates a token (cf. figure 2). Since the job posting process is carried out more than once, many tokens can be created in the course of time. Thereby it can happen that the process for one job posting is not yet finished, when the process for posting another job starts. As it moves through the process, each token is independent from the other tokens’movements.Figure 2: A start event creates a tokenThe token that has been created by the start event moves through the sequence flow to the first activity. This activity receives a token, performs its task (in this case it reports a job opening), and then releases it to the outgoing sequence flow (cf. figure 3).Figure 3: An activity receives a token and forwards it after completionThe following activity forwards the token. It then arrives at the merging exclusive gateway. The task of this gateway is simple: It just takes a token that arrives via any incoming sequence flow and moves it to the outgoing sequence flow. This is shown in figure 4. In case A, a token arrives from the left, in case B from below. In both cases the token is routed to the outgoing sequence flow to the right.Figure 4: Routing of a token by a merging exclusive gatewayThe task of the splitting exclusive gateway is more interesting. It takes one arriving token and decides according to the conditions, to which sequence flow it should be moved. In case A in figure 5, the condition “okay”is true, i.e. the preceding review activity has produced a positive result. In this case, the token is moved to the right. Otherwise, if the condition “not okay”is true, the token is moved to the downwards sequence flow (case B).The modeler must define the conditions in such a way that always exactly one of the conditions is true. The BPMN specification does not state how to define conditions and how to check whichconditions are true. Since the considered process is not executed by software, the rather simple statements used here are sufficient. Otherwise, it would be necessary to define the conditions according to the requirements and rules of the software tool.The token may travel several times through the loop for reworking the job posting. Finally it arrives at the end event. This simply removes any arriving token and thus finishes the entire process (figure 6).Figure 5: Routing of a token by a splitting exclusive gatewayThe sequence flow of every process diagram can be simulated in this way with the help of tokens. This allows for analyzing whether the flow logic of a process has been modeled correctly.It should be noted that a token does not represent such a thing as a data object or a document. In the case of the job posting process, it could be imagined to have a document “job posting”flowing through the process. This document could contain all required data, such as the result of the activity “Review Job Posting”. At the splitting gateway, the decision could then be based on this attribute value. However, the BPMN sequence flow is constrained to the pure order of execution. The tokens therefore do not carry any information, other than a unique identifier for distinguishing the tokens from each other. For data objects there are separate BPMN constructs which will be presented in chapter 10.2.4 Presentation OptionsUsually pools are drawn horizontally. The preferred direction of sequence flow is then from left to right. On the other hand, it is also possible to use vertical pools and to draw the sequence flow from top to bottom, as in the example in figure 7.It makes sense to decide for only one of these possibilities –horizontal or vertical. Nevertheless there are modeling tools which only support horizontal modelingFigure 6: An end event removes an arriving tokenFigure 7: Vertical swimlanes and nested lanesFigure 7 also shows an example of nested lanes. The lane labeled “Sales”is partitioned into the two lanes “Sales Force”and “Order Processing”. In principle it is possible to partition these lanes again, etc., although this only makes sense up to a certain level of depth.It is not prescribed where to place the names of pools and lanes. Typical are the variants selected for figure 1 and figure 7. Here the names are placed on the left of the pools or lanes, or at the top for the vertical style, respectively. The name of a pool is separated by a line. The names of the lanes, however, are placed directly within the lanes. A separation line is only used for a lane that is partitioned into further sub-lanes. Lanes can also be arranged as a matrix. The procurement process in figure 8 runs through a business department and the procurement department, both of which span a branch office and the headquarters. When a demand occurs in a branch’s business department, this department reports the demand. In the next step, the procurement is approved by the same department in the headquarters. The central part of the procurement department then closes a contract with a supplier, followed by the branch’s purchasing department carrying out the purchase locally.Although the BPMN specification explicitly describes the possibility of such a matrix presentation, it is hardly ever applied, so far.12.2 Message CorrelationThe contents of the message flows within one conversation are always related to each other. For example, all messages that are exchanged within one instance of the conversation “Process Order for Advertisement”relate to the same advertisement order. It is therefore possible to use the order ID for the correlation, i.e. the assignment of messages to a process instance. If a customer receives an advertisement for approval, he can determine the corresponding order –and thus the process instance –based on the order ID. All messages of a conversation have a common correlation.A simple conversation which is not broken down into other conversations is called communication. Therefore, the lines are called communication links (the specification draft at some places alsocalls them conversation links). A conversation has always communication links to two or more participants.If the end of a communication link is forked, multiple partners of the same type can be part of the communication, otherwise exactly one. “Process Order for Advertisement”has exactly one customer and one advertising agency as participants, but multiple designers. Therefore, the designer’s pool contains a multiple marker. However, having only the multiple marker in the pool is not sufficient. The conversation “Handle order for an illustration”, for example, has only one designer as participant. Therefore, the respective end of the communication link is not forked.12.3 Hierarchies of ConversationsBesides communications, it is also possible to use sub-conversations. Similar to sub-processes they are marked with a ‘+’-sign. The details of a sub-conversation can be described in another conversation diagram. The diagram of a sub-conversation can only contain those participants who are linked to the sub-conversation within the parent diagram.Figure 171 shows the detailed conversation diagram for the sub-conversation “Process Order for Advertisement”As can be seen from this diagram, it is also possible to draw message flows directly into the conversation diagram. Other than collaboration diagrams, conversation diagrams are not allowed to show processes in the pools or choreographies between the pools.Figure 171: Conversation diagram for sub-conversation “Process Order for Advertisement”The diagram contains those message flows that are related to the same order. To be more precise, they relate to the same inquiry. At the beginning, an order has not been placed yet, and not every inquiry turns into an order. Therefore, the common reference point is the inquiry.Besides the explicitly displayed message flows between customer and advertising agency, the diagram also contains the communication “Assignment of Graphics Design”. All message flows of this communication are also related to the same inquiry, but this information is not sufficient for the advertising agency in order to assign all incoming messages correctly. This is due to the fact that availability requests are sent to several designers. The advertising agency has to correctly assign each incoming availability notice to the correct availability request. Thus, additional information is required for correlating these messages, e.g. the IDs of the availability requests.Therefore it is possible to define a separate communication for the message flows between advertising agency and designer. The message exchanges of this communication can also be modeled in a collaboration diagram (figure 172) or in a choreography diagram (figure 173). Of course, it is also possible to show the message flows of the entire sub-conversation within a single diagram (figures 161 and 162 in the previous chapter).Figure 172: Collaboration diagram for communication “Assignment of Graphics Design”Like sub-processes, sub-conversations can also be expanded, i.e. the hexagon is enlarged, and the detailed conversation is shown in its interior. However, it is graphically not easy to include, for example, the contents of figure 171 into an expanded sub-conversation in figure 170. Unfortunately, the BPMN specification draft does not contain any examples for expandedsub-conversations either.。

One of the main functions of the ITS is to improve transportation environment and alleviate the transportation jam, the most effective method to gain the aim is to forecast the traffic volume of the local network and the important nodes exactly with GIS function of path analysis and correlation mathematic methods, and this will lead a better planning of the traffic network. Traffic assignment forecast is an important phase of traffic volume forecast. It will assign the forecasted traffic to every way in the traffic sector. If the traffic volume of certain road is too big, which would bring on traffic jam, planners must consider the adoption of new roads or improving existing roads to alleviate the traffic congestion situation. This study attempts to present an improved traffic assignment forecast model, MPCC, based on analyzing the advantages and disadvantages of classic traffic assignment forecast models, and test the validity of the improved model in practice.1 Analysis of classic models1.1 Shortcut traffic assignmentShortcut traffic assignment is a static traffic assignment method. In this method, the traffic load impact in the vehicles’ travel is not considered, and the traffic impedance (travel time) is a constant. The traffic volume of every origination-destination couple will be assigned to the shortcut between the origination and destination, while the traffic volume of other roads in this sector is null. This assignment method has the advantage of simple calculation; however, uneven distribution of the traffic volume is its obvious shortcoming. Using this assignment method, the assignment traffic volume will be concentrated on the shortcut, which isobviously not realistic. However, shortcut traffic assignment is the basis of all theother traffic assignment methods.1.2 Multi-ways probability assignmentIn reality, travelers always want to choose the shortcut to the destination, whichis called the shortcut factor; however, as the complexity of the traffic network, thepath chosen may not necessarily be the shortcut, which is called the random factor.Although every traveler hopes to follow the shortcut, there are some whose choice isnot the shortcut in fact. The shorter the path is, the greater the probability of beingchosen is; the longer the path is, the smaller the probability of being chosen is.Therefore, the multi-ways probability assignment model is guided by the LOGIT model:∑---=n j ii i F F p 1)exp()exp(θθ (1)Where i p is the probability of the path section i; i F is the travel time of thepath section i; θ is the transport decision parameter, which is calculated by the followprinciple: firstly, calculate the i p with different θ (from 0 to 1), then find the θwhich makes i p the most proximate to the actual i p .The shortcut factor and the random factor is considered in multi-ways probabilityassignment, therefore, the assignment result is more reasonable, but the relationshipbetween traffic impedance and traffic load and road capacity is not considered in thismethod, which leads to the assignment result is imprecise in more crowded trafficnetwork. We attempt to improve the accuracy through integrating the several elements above in one model-MPCC.2 Multi-ways probability and capacity constraint model2.1 Rational path aggregateIn order to make the improved model more reasonable in the application, theconcept of rational path aggregate has been proposed. The rational path aggregate,which is the foundation of MPCC model, constrains the calculation scope. Rationalpath aggregate refers to the aggregate of paths between starts and ends of the trafficsector, defined by inner nodes ascertained by the following rules: the distancebetween the next inner node and the start can not be shorter than the distance betweenthe current one and the start; at the same time, the distance between the next innernode and the end can not be longer than the distance between the current one and theend. The multi-ways probability assignment model will be only used in the rationalpath aggregate to assign the forecast traffic volume, and this will greatly enhance theapplicability of this model.2.2 Model assumption1) Traffic impedance is not a constant. It is decided by the vehicle characteristicand the current traffic situation.2) The traffic impedance which travelers estimate is random and imprecise.3) Every traveler chooses the path from respective rational path aggregate.Based on the assumptions above, we can use the MPCC model to assign thetraffic volume in the sector of origination-destination couples.2.3 Calculation of path traffic impedanceActually, travelers have different understanding to path traffic impedance, butgenerally, the travel cost, which is mainly made up of forecast travel time, travellength and forecast travel outlay, is considered the traffic impedance. Eq. (2) displaysthis relationship. a a a a F L T C γβα++= (2)Where a C is the traffic impedance of the path section a; a T is the forecast traveltime of the path section a; a L is the travel length of the path section a; a F is theforecast travel outlay of the path section a; α, β, γ are the weight value of that threeelements which impact the traffic impedance. For a certain path section, there aredifferent α, β and γ value for different vehicles. We can get the weighted average of α,β and γ of each path section from the statistic percent of each type of vehicle in thepath section.2.4 Chosen probability in MPCCActually, travelers always want to follow the best path (broad sense shortcut), butbecause of the impact of random factor, travelers just can choose the path which is ofthe smallest traffic impedance they estimate by themselves. It is the key point ofMPCC. According to the random utility theory of economics, if traffic impedance is considered as the negativeutility, the chosen probability rs p of origination-destinationpoints couple (r, s) should follow LOGIT model:∑---=n j jrs rs bC bC p 1)exp()exp( (3) where rs p is the chosen probability of the pathsection (r, s);rs C is the traffic impedance of the path sect-ion (r, s); j C is the trafficimpedance of each path section in the forecast traffic sector; b reflects the travelers’cognition to the traffic impedance of paths in the traffic sector, which has reverseratio to its deviation. If b → ∞ , the deviation of understanding extent of trafficimpedance approaches to 0. In this case, all the travelers will follow the path whichis of the smallest traffic impedance, which equals to the assignment results withShortcut Traffic Assignment. Contrarily, if b → 0, travelers ’ understanding error approaches infinity. In this case, the paths travelers choose are scattered. There is anobjection that b is of dimension in Eq.(3). Because the deviation of b should beknown before, it is difficult to determine the value of b. Therefore, Eq.(3) is improvedas follows:∑---=n j OD j OD rsrs C bC C bC p 1)exp()exp(，∑-=n j j OD C n C 11（4） Where OD C is the average of the traffic impedance of all the as-signed paths; bwhich is of no dimension, just has relationship to the rational path aggregate, ratherthan the traffic impedance. According to actual observation, the range of b which is anexperience value is generally between 3.00 to 4.00. For the more crowded cityinternal roads, b is normally between 3.00 and 3.50.2.5 Flow of MPCCMPCC model combines the idea of multi-ways probability assignment anditerative capacity constraint traffic assignment.Firstly, we can get the geometric information of the road network and OD trafficvolume from related data. Then we determine the rational path aggregate with themethod which is explained in Section 2.1.Secondly, we can calculate the traffic impedance of each path section with Eq.(2),Fig.1 Flowchart of MPCC which is expatiated in Section 2.3.Thirdly, on the foundation of the traffic impedance of each path section, we cancalculate the respective forecast traffic volume of every path section with improvedLOGIT model (Eq.(4)) in Section 2.4, which is the key point of MPCC.Fourthly, through the calculation processabove, we can get the chosen probability andforecast traffic volume of each path section, but itis not the end. We must recalculate the trafficimpedance again in the new traffic volumesituation. As is shown in Fig.1, because of theconsideration of the relationship between trafficimpedance and traffic load, the traffic impedanceand forecast assignment traffic volume of everypath will be continually amended. Using therelationship model between average speed andtraffic volume, we can calculate the travel timeand the traffic impedance of certain path sect-ionunder different traffic volume situation. For theroads with different technical levels, therelationship models between average speeds totraffic volume are as follows: 1) Highway: 1082.049.179AN V = (5) 2) Level 1 Roads: 11433.084.155AN V = (6) 3) Level 2 Roads: 66.091.057.112AN V = (7) 4) Level 3 Roads: 3.132.01.99AN V = (8) 5) Level 4 Roads: 0988.05.70A N V =(9) Where V is the average speed of the path section; A N is the traffic volume of thepath section.At the end, we can repeat assigning traffic volume of path sections with themethod in previous step, which is the idea of iterative capacity constraint assignment,until the traffic volume of every path section is stable.译文智能交通交通量分配预测模型介绍随着城市的可持续化发展、数字化城市的建设以及交通运输业的发展，智能交通系统（ITS）的发展越来越快。

WHAT MY FATHER WORE——From Chicken soup for the soul What my father wore embarrassed me as a young man, I wanted him to dress like a doctor or lawyer, but on those muggy mornings when he rose before dawn to fry eggs for my mother and me, he always dressed like my father.We lived in south Texas, and my father wore tattered jeans with the imprint of his pocket knife on the seat. He liked shirts that snapped more than those that buttoned, and kept his pencils, cigars, glasses, wrenches and screwdrivers in his breast pocket. My father's boots were governmentissues with steel toes that made them difficult to pull off his feet, which I sometimes did when he returned from repairing air conditioners, his job that also shamed me.I blamed the way he dressed for my social failures. When boys bullied me, I thought they'd seen my father wearing his cowboy hat but no shirt while walking our dog. I felt that girls snickered at me because they'd glimpsed him mowing the grass in cutoffs and black boots The girls' families paid men (and I believed betterdressed ones) to landscape their lawns, while their fathers yachted in the bay wearing lemonyellow sweaters and expensive sandals.My father only bought two suits in his life. He preferred clothes that allowed him the freedom to move under cars and squeeze behind broken Maytags, where he felt most content. But the day before my parents' twentieth anniversary, he and I went to Sears, and he tried on suits all afternoon.With each one, he stepped to the mirror, smiled and nodded, then asked about the price and reached for another. He probably tried ten suits before we drove to a discount store and bought one without so much as approaching a fitting room. That night my mother said she'd never seen a more handsome man.Later, he donned the same suit for my eighthgrade awards banquet, and I wished he'd stayed home. After the ceremony, he lauded my award and mycharacter while changing into a faded red sweatsuit. He was stepping into the garage to wash a load of laundry when I asked what even at age fourteen struck means cruel and wrong. “Why," I asked, "don't you dress 'nice', like my friends' fathers?"He held me with his sad, shocked eyes and searched for an answer. Then before he disappeared into the garage and closed the door between us, my father said, “I like my clothes.” An hour later my mother stormed into my room and called me an “ungrateful little twerp", a phrase that echoed in my head.In time they forgave me, and as I matured I realized that girls avoided me not because of my father but because of his son. I realized that my mother had scolded me because my father could not, and it soon became clear that what he had really said that night was that there are things more important than clothes. He'd said he couldn't spend a nickel on himself because there were things I wanted. That night, without another word, my father had said, “You're my son, and I sacrifice so your life will be better than mine.”For my highschool graduation, my father arrived in a suit he and my mother had purchased earlier that day. Somehow he seemed taller, more handsome and imposing, and when he passed the other fathers they stepped out of his way. It wasn't the suit, of course, but the man. The doctors and lawyers recognized the confidence in his swagger, the pride in his eyes, and when they approached him, they did so with courtesy and respect. After we returned home, my father replaced the suit in the flimsy Sears garment bag, and I didn't see it again until his funeral.On the morning of the services, I used his pocket knife to carve a hole in his belt so it wouldn't droop around my waist. Then I took the suit from Sears out of his closet and changed into it. Eventually, I mustered the courage to study myself in his mirror where, with the exception of the suit, I appeared small and insignificant. My father's scent wafted up and caressed my face, but it failed to console me. I was certain: Not about my father's stature I'd stopped being an ungrateful little twerp years before.我小的时候，我父亲穿的衣服让我很尴尬。

【原文】Of Studies——Francis Bacon Studies serve for delight, for ornament, and for ability. Their chief use for delight, is in privateness and retiring; for ornament, is in discourse; and for ability, is in the judgment and disposition of business. For expert men can execute, and perhaps judge of particulars, one by one; but the general counsels, and the plots and marshalling of affairs come best from those that are learned.To spend too much time in studies is sloth; to use them too much for ornament is affection; to make judgment wholly by their rules is the humor of a scholar. They perfect nature and are perfected by experience: for natural abilities are like natural plants, that need pruning by study, and studies themselves do give forth directions too much at large, except they be bounded in by experience.Crafty men contemn studies, simple men admire them, and wise men use them, for they teach not their own use; but that is a wisdom without them and above them, won by observation. Read not to contradict and confuse; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider.Some books are to be tasted, others to be swallowed, and some few to be chewed and digested; that is some books are to be read only in parts; others to be read, but not curiously; and somefew to be ready wholly, and with diligence and attention. Some books also may be read by deputy and extracts made of them by others; but that would be only in the less important arguments, and the meaner sort of books; else distilled books are, like common distilled waters, flashy things.Reading makes a full man; conference a ready man; and writing an exact man. And therefore, if a man write little, he had need have a great memory; if he confer little, he had need have a present wit; and if he read little, he had need have much cunning to seem to know that he doth not.Histories make men wise; poets witty; the mathematics subtle; natural philosophy deep; moral grave; logic and rhetoric able to contend.Abeunt studia in mores. Nay there is no stond or impediment in the wit, but may be wrought out by fit studies: like as diseases of the body may have appropriate exercises. Bowling is good for the stone and reins; shooting for the lungs and breast; gentle walking for the stomach; riding for the head; and the like. So if a man’s wit be wandering, let him study the mathematics; for in demonstrations, if his wit be called away never so little, he must begin again. If his wit be not apt to distinguish or find differences, let him study the schoolmen; for they are cymini sectores. If he be not apt to beat over matters, and to call up one thing to prove andillustrate another, let him study the lawyers’ cases. So every defect of the mind may have a special receipt.谈读书——王佐良译读书足以怡情，足以博彩，足以长才。
2020中译国青杯英译汉原文
“中译国青杯”联合国文件翻译大赛学生组——英译汉【原文】Australia: Where Nature is Grieving“When you walk into a forest that’s been burnt this badly, the overwhelming thing that hits you is the silence. No bird-song. No rus tling of leaves. Silence.” This is how Mike Clarke, professor of zoology at La Trobe University, Melbourne, describes Australia’s many forests recently decimated by bushfires.“This stands out as the worst disaster in Australia’s recorded history,” Clarke says. The figure of the area that has been burnt – 13 million hectares –is “hard to get your head around.” For scale, this is an area bigger in hectares than Holland, Denmark and Switzerland combined. All burnt to a crisp. Homes, forests, animals, plants –everything in the wake of these intense infernos – incinerated. Gone.Unprecedented scaleAt least a billion animals were killed in the bushfires, according to approximate estimates by Chris Dickman, professor in territorial ecology at The University of Sydney. This figure is conservative, Clarke believes. “That’s just mammals, birds, reptiles. If we added invertebrates to that, the numbers would be astronomical.”One thing that must be clear, though, is that Australia’s bush has always burnt quite s everely. “The severity isn’t unprecedented,” says Alan York, professor of Fire Ecology at the University of Melbourne. “What is unprecedented is their earliness in, or before the usual fire season, and the volume of fires in so many places, which is far mo re unusual.”Koalas in northern New South Wales have had most of their habitat burnt. “Speculation is that populations will become locally extinct,” according to York. The iconic nature of the koalas sometimes overshadows other ecosystem horrors, Clarke ad ds. “They’re the poster child of this crisis. But in reality, a whole suite of wildlife – large possums, all sorts of plants that live in alpine ash, whole communities of organisms – are all at risk now.”The resilience of the Australian bush in questionIt may take years for these species to recover. And that may require human assistance, with captive-bred frogs in Australia’s zoos, for example. “Otherwise, we’re hoping animals survived in unburnt pockets,” York explains. He remains somewhat optimistic, s aying the Australian bush has a “dramatic capacity to recover.”There are, however, caveats. Rainforests and alpine areas of Tasmania, for instance, don’t have much experience of fires, so they’re more vulnerable to repeated fires, he says. And under the current climate change model, increasing fires are inevitable.Some of several “human interferences” that’ll most likely hamper recovery include habitat removal from land clearing; introducing feral species which prey on native species (feral cats have been known to come from ten kilometres away to the edge of a fire to pick off prey, usually native); and a lack of urgent political action on climate change.The problem is, lots of critical resources have been incinerated. For example, many fauna – cockatoos, parrots, possums, bats – rely on hollow logs on the ground, or on trees to den in or breed in. Not only have those logs now gone, Clarke predicts that it will take one to two centuries for them to appear again, hollowed out. “A lot of Australian wood is hardwood. Fungi and termites hollow it really slowly. There are no woodpeckers here,” he explains. Suddenly, the capacity to recover seems almost insurmountable within our lifetime. “What could disappear in hours in bushfire could take centuries to replace. Ecologists would call this a ‘complete state change’.”Immediate measures neededExperts say some immediate steps are being taken to help along the recovery of this vast area. A moratorium on logging has been proposed, and pressure is building to act more aggressively on the pest control of feral cats and foxes, in addition to introducing weed removal. “Weeds recolonize areas disturbed by fire. They use resources that native plants and animals might need,” York explains.Identifying and protecting areas that did not burn is also an important subject for debate. Specifically, some are arguing that cultural burns may be better than the hotter, more intense, hazard reduction burning. Cultural burns are cool-burning, knee-high blazes that were designed to happen continuously and across the landscape, practised by indigenous people long before Australia’s invasion and colonization. The fires burn up fuel like kindling and leaf detritus, so that a natural bushfire has less to devour.Since Australia's fire crisis began last year, calls for better reintegration of this technique have grown louder. But they may be of limited value at this crisis point, according to Clarke. “We need to appreciate how different things are now. Cultural burns happened to enable people to move through dense vegetation easily, or for ceremonial reasons. They weren’t burning around 25 million people, criss-crossed by complex infrastructure and in a climate change scenario,” he estimates.Concrete measures to combat climate change are indeed crucial for the future of biodiversity. In spite of green shoots of optimism in some quarters, the prognosis of whether the bush will ever recover its biodiversity is looking somewhat grim. Breaking it down, Clarke surmises that “A chunk of it will be good – a third will be able to bounce back. A third is in question, but a third is in serious trouble. I’ve been studyingfire ecology for twenty years, but we’re de aling with unchartered territory changing before our eyes.”【参赛译文格式要求】一、参赛译文应为Word文档.doc或.docx格式。
交通运输交通系统中英文对照外文翻译文献
中英文对照外文翻译文献(文档含英文原文和中文翻译)译文：交通系统交通运输一直是土木工程最重要的一个方面。
古罗马工程师的巨大成就之一就是公路系统，它使罗马与帝国的各个省之间的快速交通成为可能。
在工程方面的第一所培训学校就是桥梁和公路学校，它于1747年创建于法国。
而在英国，一位道路建筑家，托马斯·泰尔福特于1820年担任了土木工程学会的第一任主席。
现代公路仍然根据18世纪及19世纪初法国人皮埃尔·特埃萨凯，英国人泰尔福特，以及苏格兰人约翰·L·马克当所制定的原则进行建造。
这些人设计出了最初的现代道路，这种道路具有坚实的垫层，基础就建在垫层的上面。
他们设计的道路还具有排水良好而且不渗水的磨耗层，即直接承受车辆交通磨耗的表层。
特埃萨凯和泰尔福特均采用较厚的石头基础，在其上面铺筑由较小碎石组成的基层和由更小的石头组成的磨耗层。
他们的道路还微微隆起成曲线，形成路拱和反拱以便使雨水流走。
马克当认识到当土壤被夯实或压紧之后，只要保证干燥，其本身就可承受道路的重量，因而他能够通过在压实的垫层上铺碎石基层来省掉建造石头基础所需要的昂贵费用。
当时车辆的铁质车轮把表层石头碾压成连续的，较为平整的，更加不透水的表面。
早19世纪，货车和客车都采用铁或钢制车轮，这种道路是适用的。
当汽车在20世纪初出现之后，其橡胶轮胎毁坏了这种平整的路面。
因此，就采用焦油或沥青掺拌碎石，使路面表层更坚固的黏合一起。
现在，遍布全世界的数百万公里的道路采用这种路面。
在20世纪，道路建设基本上仅在两方面进行了改进。
第一种改进是采用混凝土作为磨耗层。
另一种改进则是交通工程，即设计高速的大交通量的、造价经济并且对于车辆和旅客都安全的公路。
交通工程已建成了现代高速公路，这种公路具有限定的入口和最安全的管理。
老式道路常用的拐角形交叉已不使用，而采用互通式立体交叉或其他更为复杂的设计。
现代高速公路通常设有专门的车道，在那里当车辆要驶出公路时可减速驶入时可加速。

英文原文Development of Sensor New TechnologySensor is one kind component which can transform the physical quantity，chemistry quantity and the biomass into electrical signal. The output signal has the different forms like the voltage, the electric current, the frequency, the pulse and so on, which can satisfy the signal transmission, processing, recording, and demonstration and control demands. So it is the automatic detection system and in the automatic control industry. If automatic Technology is used wider, then sensor is more important. In information age, the information industry includes information gathering, transmission, process three parts, namely sensor technology, communication, computer technology. Because of ultra large scale integrated circuit’s rapid development after having been developed ,Modern computer technology and communication, not only requests sensor precision, reliability, speed of response and gain information, content request more and more high, but also requests its cost to be inexpensive. The obvious traditional sensor is eliminated gradually because of the function，the characteristic, the volume, the cost and so on. As world develop many countries are speeding up to the sensor new technology’s research and the development, and all has obtained the enormous breakthrough. Now the sensor new technology development mainly has following several aspects:Firstly, discovering and usingUsing the physical phenomenon, the chemical reaction, the biological effect as the sensor principle therefore the researches which discovered the new phenomenon and the new effect are the sensor technological improving ways .It is important studies to develop new sensor’s the foundation. Japanese Sharp Corporation uses the superconductivity technology to develop successfully the high temperature super conductivity magnetic sensor and get the sensor technology significant breakthrough. Its sensitivity is so high and only inferior in the superconductivity quantum interference component. May use in magnetism image formation technology. So it has the widespread promoted value.Using the immune body and the antigen meets one another compound when the electrode surface. It can cause the electrode potential change and use this phenomenon to be possible to generate the immunity sensor. The immunity sensor makes with this kind of immune body may to some organism in whether has this kind of anti-original work inspection. Like may inspect somebody with the hepatitis virus immune body whether contracts the hepatitis, plays to is fast, the accurate role. The USUC sixth branch hasdeveloped this kind of sensor.Secondly, using the new materialThe sensor material is the important foundation for sensor technology, because the materials science is progressive and the people may make each kind of new sensor. For example making the temperature sensor with the high polymer thin film; The optical fiber can make the pressure, the current capacity, the temperature, the displacement and so on the many kinds of sensors; Making the pressure transmitter with the ceramics. The high polymer can become the proportion adsorption and the release hydrone along with the environment relative humidity size. The high polymer electricity lies between the constant to be small, the hydrone can enhance the polymer the coefficient of dielectric loss. Making the capacitor the high polymer dielectric medium, determines the electric capacity the change, then obtains the relative humidity. Making the plasma using this principle to gather the legitimate polystyrene film temperature sensor below, it has the characteristic: Measured the wet scope is wide;The temperature range is wide, may reach -400 ℃~ +1500 ℃;The speed of response is quick, is smaller than 1S;The size is small, may use in the small space measuring wet;The temperature coefficient is small.The ceramic electric capacity type pressure transmitter is one kind does not have the intermediary fluid the dry type pressure transmitter. Uses the advanced ceramic technology, the heavy film electronic technology, its technical performance is stable, the year drifting quantity is smaller than 0.1%F.S, warm floats is smaller than ±0.15%/10K, anti- overloads strongly, may reach the measuring range several hundred times. The survey scope may from 0 to 60mpa. German E+H Corporation the American Kav lio Corporation product is at the leading position.The optical fiber application is send the material significant breakthrough, its uses in most early the optical communication techniques. In the optical communication use discovered works as environmental condition change and so on the temperature, pressure, electric field, magnetic field, causes the fiber optic transmission light wave intensity, the phase, the frequency, change and so on the polarization condition, the survey light wave quantity change, may know causes these light wave physical quantity the and so on quantitative change temperature , pressure , electric field, magnetic field size, uses these principles to be possible to develop the optical fiber sensor. The optical fiber sensor and the traditional sensor compare has many characteristics: Sensitivity high, the structure simple,the volume small, anti-corrosive the electric insulation good, the path of rays may be curving, be advantageous for the realization telemeter and so on. Optical fiber sensor Japan is in the advanced level .Like Idec Izumi Corporation and Sun Corporation. The optical fiber send receiver and the integrated path of rays technology unify, accelerates the optical fiber sensor technology development. Will integrate the path of ray’s component to replace the original optics part and the passive light component; enable the optical fiber sensor to have the high band width, the low signal processing voltage, the reliability high, the cost will be low.Third, micro machine-finishing technologyIn semiconductor technology processing method oxygenation, the photo etching the proliferation, the deposition, the plane electron craft, various guide corrosion and steams plates, the sputtering thin film and so on, these have all introduced to the sensor manufacture. Thus has produced each kind of new sensor, like makes the silicon micro sensor using the semiconductor technology, makes the fast response using the thin film craft the gas to be sensitive, the wet sensitive sensor, the use sputtering thin film craft system pressure transmitter and so on.The Japanese horizontal river company uses various guide corrosion technology to carry on the high accuracy three dimensional processing, the system helps the silicon resonance type pressure transmitter. The core partially presses two resonant Liang by the feeling which above the silicon diaphragm and the silicon diaphragm manufactures to form, two resonant Liang's frequency difference correspondence different pressure, measures the pressure with the frequency difference method, and may eliminate the error which factor and so on ambient temperature brings. When ambient temperature change, two resonant Liang frequencies and the amplitude variation are same, after two frequency differences, its same change quantity can counterbalance mutually. Its survey most high accuracy may reach 0.01%FS.American Silicon Microstructure Inc .（SMI）the company develops a series of low ends, linear in 0.1% to 0.In 65% scope silicon micro pressure transmitter, the lowest full measuring range is 0.15psi （1KPa）, it makes take the silicon as the material, has the unique three dimensional structure, the light slight machine-finishing, makes the wheat stone bridge many times with the etching on the silicon diaphragm, when above silicon chip stress, it has the distortion, the resistance produces presses the anti-effect but to lose the bridge balance, the output and the pressure becomes the proportion the electrical signal.Such silicon micro sensor is the front technology which now the sensor develops, itsessential feature is the sensitive unit volume is a micron magnitude, is the traditional sensor several dozens, several 1%. In aspect and so on industry control, aerospace domain, biomedicine has the vital role, like on the airplane the use may reduce the airplane weight, reduces the energy. Another characteristic is can be sensitive is small surveyed, may make the blood pressure transmitter.The Chinese aviation main corporation Beijing observation and control technical research institute, the development CYJ series splashes thanks the membrane pressure transmitter is uses the ion sputtering craft to process the metal strain gauge, it has overcome the nonmetallic strain gauge easily the temperature influence insufficiency, has the high stability, is suitable in each kind of situation, is measured the medium scope widely, but also overcame the tradition lowly to glue the precision which the type brought, sluggish big, shortcoming and so on slow change, had the precision high, the reliability is high, the volume small characteristic, widely used in domain and so on aviation, petroleum, chemical industry, medical service.Fourth, integrates the sensorIntegrates the sensor the superiority is the traditional sensor is unable to achieve, it is a simple sensor not merely, it in at the same time the auxiliary circuit part and send the part will integrate on together the chip, will cause it to have the calibration, to compensate, from the diagnosis and the network correspondence function, it might reduce the cost, the gain in yield, this kind of blood pressure sensor which American LUCAS, NOV ASENSOR Corporation will develop, each week will be able to produce 10,000.Fifth, intellectualized sensorThe intellectualized sensor is one kind of belt microprocessor sensor, is achievement which the microcomputer and the sensor unifies, it has at the same time the examination, the judgment and the information processing function, compares with the traditional sensor has very many characteristics:Has the judgment and the information processing function, can carry on the revision, the error to the observed value compensates, thus enhancement measuring accuracy;May realize the multi-sensor multi parameters survey;Has from the diagnosis and from the calibration function, enhances the reliability;The survey data may deposit and withdraw, easy to operate;It has the data communication interface, can and the microcomputer direct communication.The sensor, the signal adjustment electric circuit, the monolithic integrated circuitintegration forms ultra large-scale integrated on a chip the senior intelligence sensor . American HONY WELL Corporation ST-3000 intelligence sensor, the chip size only then has 3×4×2mm, uses the semiconductor craft, makes CPU,EPROM, the static pressure, the differential pressure, the temperature on the identical chip and so on three kind of sensitive units.The intellectualized sensor research and the development, US are at the leading position. American Space Agency when development spaceship called this kind of sensor for the clever sensor （Smart Sensor）, on the spaceship this kind of sensor is extremely important. Our country in this aspect research and development is also very backwards, mainly is because our country semiconductor integrated circuit technological level is limited.The sensor’s development is changing day after day since specially in the 80's humanities have entered into the high industrialization the information age, sensor technology to renewal, higher technological development. US, Japan and so on developed country sensor technological development quickest, our country because the foundation is weak, the sensor technology compares with these developed countries has the big disparity. Therefore, we should enlarge to the sensor engineering research, the development investment, causes our country sensor technology and the foreign disparity reduces, promotes our country instrument measuring appliance industry and from the technical development.中文译文传感器新技术的发展传感器是一种能将物理量、化学量、生物量等转换成电信号的器件。
