2016年专业英语历年考试真题
2016年专业英语历年考试真题The year 2016 marked a significant milestone in the history of specialized English exams, as it saw the introduction of several key changes that reshaped the testing landscape. As we delve into the past exam papers, it becomes evident that the focus shifted towards a more practical and context-based approach, emphasizing real-world applications of English rather than just rote learning.The reading comprehension sections of the 2016 exams were particularly noteworthy for their diverse range of topics, ranging from scientific research articles to business case studies. This shift towards a more diverse content mix reflects a growing trend towards assessing candidates' ability to comprehend and analyze complex texts across different domains. Candidates were required to not only understand the literal meaning of the text but also to infer implied meanings, understand the author's intentions, and evaluate the credibility of the information presented.The listening comprehension sections also saw a similar trend, with conversations and lectures being designed to test the candidates' ability to extract key information, understand context, and make logical deductions. This section tested the candidates' active listening skills, requiring them to actively engage with the audio material and interpret it quickly and accurately.The writing sections of the exams were also updated to reflect this new focus on practicality and real-world applications. Candidates were asked to write essays and reports that模拟真实工作场景中的写作任务， emphasizing clarity, coherence, and the ability to communicate ideas effectively. The emphasis on these skills is crucial in today's globalized workforce, where effective communication is a prerequisite for success.In the light of these changes, it is important for candidates to adopt a strategic approach towards their preparation. Firstly, they should focus on developing a strong foundation in the basic language skills of reading, writing, listening, and speaking. This foundation willprovide them with the necessary tools to tackle the more complex tasks presented in the exams.Secondly, candidates should expose themselves to a wide range of materials, including newspapers, magazines, podcasts, and online resources, to familiarize themselves with different styles and registers of English. This will help them adapt to the diverse content mix found in the exams.Thirdly, candidates should practice regularly, focusing on improving their speed and accuracy. This can be achieved through timed practice tests and mock exams, which willhelp them familiarize themselves with the exam format and develop the necessary test-taking skills.Lastly, candidates should focus on developing their critical thinking skills. This involves analyzing and evaluating information, identifying arguments and counterarguments, and drawing conclusions based on evidence. These skills will be crucial in the writing and reading comprehension sections of the exams.In conclusion, the 2016 professional English exams marked a significant shift towards a more practical andcontext-based approach. Candidates need to prepare strategically, focusing on developing a strong foundationin basic language skills, exposing themselves to a wide range of materials, practicing regularly, and developing critical thinking skills. By doing so, they will be well-prepared to face the challenges of the exams and succeed in their professional careers.**2016年专业英语历年考试真题深度解析与备考策略**2016年对于专业英语考试来说，是一个具有里程碑意义的年份，因为这一年见证了一系列重大变革，重塑了考试格局。
物理学专业英语A5
A5 Magnets and currents
• The region around a magnet where magnetic forces act is sometimes called a magnetic field. However, see B17 for a more precise definition of a magnetic field. In diagrams, a magnetic field is represented by field lines. The stronger the field, the closer the lines. The direction of the field is the direction in which a 'free' N pole would move (though in reality, magnetic poles always exist in pairs).
A5 Magnets and currents
• Generating AC • In the generator above, a coil is rotated in a magnetic field. This induces an EMF in the coil, so a current flows. The current keeps changing direction as the coil faces first one way and then the other: it is alternating current (AC). A generator which produces AC is called an alternator. • 'One way' current from a battery is direct current (DC).

The most important of these engineers was Isambard Kingdom Brunel, whose work in shipping, bridge-building, and railway construction, to name just three fields, both challenged and motivated his colleagues. He was the driving force behind a number of the hugely ambitious projects, some of which resulted in works which are still in use today.The son of an engineer, Brunel apprenticed with his father at an early age on the building of the Thames Tunnel. At the age of just twenty, he became engineer in charge of the project. This impressive plan to bore under the Thames twice suffered two major disasters when the river broke through into the tunnel when the second breach(决口)occurred in 1872, Brunel was seriously injured during rescue operation and further work was halted.While recovering from his injuries, Brunel entered a design competition for a new bridge over the Avon Gorge near Clifton. The original judge of the competition was Thomas Telford, a leading civil engineer of his day, who rejected all entries to the competition in favor of his own design. After considerable scandal, a second contest was held and Brunel's design was accepted. For reasons of funding, however, exacerbated(加剧) by social unrest in Bristol, the project was abandoned in 1843 with only the towers completed. After Brunel’s death, it was decided to begin work on it again, partly so that the bridge could form a fitting memorial to the great engineer. The entire structure was finally completed in 1864. Today, the well-known Clifton Suspension Bridge is a symbol of Bristol, just as the Opera House is of Sydney. Originally intended only for horse-drawn traffic, the bridge now bears over four million motor vehicles a year.16.【题干】Brunel was an important airplane engineer in Britain during the Industrial Revolution.【选项】A.RightB.WrongC.Not mentioned【答案】C【解析】17.【题干】Brunel was involved less in railway construction than in other engineering fields.【选项】A.RightB.WrongC.Not mentioned【答案】C【解析】18.【题干】Brunel worked only on shipping, bridge-building and railway construction.【选项】A.RightB.WrongC.Not mentioned【答案】B【解析】19.【题干】Brunel work was largely ignored by his colleagues.【选项】A.RightB.Wrong【答案】B【解析】20.【题干】Some projects Brunel contributed to are still in use today.【选项】A.RightB.WrongC.Not mentioned【答案】A【解析】21.【题干】Brunel became an apprentice with his father when he was very young.【选项】A.RightB.WrongC.Not mentioned【答案】A【解析】22.【题干】The Thames Tunnel project was more difficult than any previous projects undertaken in Britain.【选项】A.RightB.Wrong【答案】C【解析】三、概括大意Geothermal(地热)Energy1.Since heat naturally moves from hotter regions to cooler ones, the heat from the earth's center flows outwards towards the surface. In this way, it transfers to the next layer of rock. If the temperature is high enough, some of this rock melts and forms magma(岩浆). The magma ascends in its turn towards the earth's surface. It often remains well below the earth's surface, creating vast areas of hot rock. In such regions, there are deep cracks, which allow rainwater to descend underground. Some of the heated rainwater travels back up to the earth's surface where it will appear as a hot spring. However, if this ascending hot water reaches a layer of impermeable(不可渗透的)rock, it remains trapped, forming a geothermal reservoir. If geothermal reservoirs are close enough to the surface, they can be reached by drilling wells. Hot water and steam shoot up the wells naturally, and can be used to produce electricity in geothermal power plants.2.A few geothermal power plants depend on dry-stem reservoirs which produce steam but little or no water. In these cases, the steam is piped up directly to provide the power to spin a turbine generator. The first geothermal power plant, constructed at Lardarello in Italy, was of this type, and is still producing electricity today.3.Most currently operating geothermal power plants are either "flash" steam plants or binary(双重的)plants. Flash plants produce mainly hot water ranging in temperature from 300° to 700°Fahrenheit. This water is passed through one or two separators where released from the pressure of the underground reservoir, it "flashes" or boils into steam Again, the force of this steam provides the energy to spin the turbine and produce electricity. The geothermal water and steam are then reinjected directly back down into the earth to maintain the volume and pressure of the reservoir. Gradually they will be reheated and can then be used again.4.A reservoir with temperatures below 300° Fahrenheit is not hot enough to flash steam but it can still be used to generate electricity in binary fluid. The steam from this is used to power the turbines. As in the flash steam plant, the geothermal water is recycled back into the reservoir.23.【题干】Paragraph1_____【选项】A.Dry steam plantsB.Binary plantsC.Origin of geothermal energyD.Generation of electricityE.Flash steam plantsF.Recyclable water and steam【答案】C【解析】24【题干】Paragraph2_____【选项】A.Dry steam plantsB.Binary plantsC.Origin of geothermal energyD.Generation of electricityE.Flash steam plantsF.Recyclable water and steam【答案】A【解析】25【题干】Paragraph3_____ 【选项】A.Dry steam plantsB.Binary plantsC.Origin of geothermal energyD.Generation of electricityE.Flash steam plantsF.Recyclable water and steam 【答案】E【解析】26【题干】Paragraph4_____ 【选项】A.Dry steam plantsB.Binary plantsC.Origin of geothermal energyD.Generation of electricityE.Flash steam plantsF.Recyclable water and steam 【答案】F【解析】27.【题干】A geothermal reservoir is formed when hot water is trapped under _____. 【选项】A.the energy to turn a turbineB.impermeable rockC.one or two separatorsD.turbine operatorE.little or no waterF.hot springs【答案】B【解析】28.【题干】A dry-steam reservoir produces steam with _____.【选项】A.the energy to turn a turbineB.impermeable rockC.one or two separatorsD.turbine operatorE.little or no waterF.hot springs【答案】E【解析】29.【题干】Flash plants produce hot water through _____.【选项】A.the energy to turn a turbineB.impermeable rockC.one or two separatorsD.turbine operatorE.little or no waterF.hot springs【答案】C【解析】30.【题干】In a binary plant, the heat of the geothermal water can be converted into _____.【选项】A.the energy to turn a turbineB.impermeable rockC.one or two separatorsD.turbine operatorE.little or no waterF.hot springs【答案】A【解析】四、阅读理解第一篇Sports Star Yao MingIf Yao Ming is not the biggest sports star in the world, he is almost certainly the tallest. At 2.26m, he is the tallest player in the National Basketball Association (NBA) and holds the record as the most towering Olympian ever to compete in the Games.But what really stands out about the giant center is his celebrity(名气). Few, if any, Chinese athletes are as well-known as Yao around the world. People across the globe are fascinated with Yao, not only for his basketball prowess(杰出的才能)also for being a symbol of international commerce.When Yao joined the Houston Rockets as the No.1 pick in the 2002 NBA draft(选抜)， he was the first international player ever to be selected first. His assets on the court are clear enough—no NBA player of his size has ever possessed his mobility, so he is a handful(难对付的人)for opponents on either end of the court. But what makes Yao invaluable to the Rockets organization is his role as a global citizen and as a bridge to millions of potential basketball fans in China.When it was announced in February that Yao would miss the rest of the NBA season and possibly the Olympics with a stress fracture(骨折)in his left foot, a collective shudder(震动)spread across China. After considerable debate and discussion, Yao opted to get his foot surgically treated in an operation that placed several tiny screws across the bone, to offer his overburdened foot more support. The surgery was a success, and though the estimated four-month recovery period will leave him little time to prepare with Team China, Yao has vowed to be ready for the Beijing Olympics.Yao wrapped up a 10-day trip to China, where he underwent a series of traditional Chinese medicine (TCM) treatments, hoping to accelerate his recovery process Western experts are generally skeptical of TCM's benefits although new research from the University of Rochester suggests that a certain compound derived from shellfish may indeed stimulate bone repair."There is no reason to dismiss TCM," Yao told a press conference in Beijing." It's been used in our country for thousands of years. I don't think that it's short on science."31.【题干】The word "towering" in Paragraph 1 means_____【选项】rge.B.fat.C.tall.D.great.【答案】C【解析】32.【题干】Opponents find it very difficult to control Yao Ming because of his_____【选项】A.mobility.B.assault.C.defense.D.celebrity.【答案】A【解析】33.【题干】Yao Ming had to undergo a series of TCM treatments because_____【选项】A.his right foot had been hurting.B.he wanted to make a more rapid recovery.C.the surgical operation had been a failure.D.he couldn't afford all the medical expenses.【答案】B【解析】34.【题干】Which statement about Yao Ming is NOT true?【选项】A.He missed the Athens Olympics.B.He is an NBA player.C.He fractured his left foot.D.He is an international figure.【答案】A【解析】35.【题干】In general, the Western experts' attitude towards TCM is_____.【选项】A.indifferent.B.positive.C.negative.D.doubtful.【答案】D【解析】第二篇Deforestation and Desertification(沙漠化）TheSahel zone lies between the Saharadesert and the fertile savannahs(热带大草原）ofnorthern Nigeria and South Sudan. The word sahel comes from Arabic and means marginal or transitional ,andthis is a good description of thesesemi-arid(半干旱）lands,whichoccupy much of the Western African countries ofMail,Mauritania,Niger,and Chad.Unfortunately, over the last century theSahara desert has steadily crept southwards eating into once productive Sahellands. United Nations surveys show that over 70 percent of the dry land inagriculture use in Africa has deterioratedover the last 30 years. Droughts have become more severe, the most recentlasting over twenty years in parts of the Sahel region. The same process ofdesertification is taking place across southern Africa as the Kalahari desertadvances into Botswana and parts of South Africa.One ofthe major causes of this desert advance ispoor agricultural land use, driven by the pressures of increasing population.Overgrazing一 keeping too many farm animals on the land一means that grasses and other plants cannot recover, and scarce water suppliesare exhausted. Overcultivation一 tryingto grow too many crops on poor land一 resultsin the soil becoming even less fertile and drier, and beginning to break up. Soilerosion (侵蚀) follows, and the land turns into desert.Another cause of desertification is loss of tree cover. Trees are cutdown for use as fuel and to clear land for agricultural use. Tree roots help tobind the soil together, to conserve moisture, and to provide a habitat forother plants and animals. When trees are cut down, the soil begins to dry andloosen, wind and rain erosion increase, other plant species die, and eventuallythe fertile top soil may be almost entirely lost, leaving only bare rock anddust.The effects of loss of topsoil and increased drought are irreversible. Theyare,however, preventable. Careful conservation of tree cover annd sustainableagricultural land use have been shown to halt deterioration of soils and lessenthe effects of shortage of rainfall. One project in Kita in south-west Malifunded by UNDP has involved local communities in sustainable management offorest,while at the same time providing a viable(有活力的）agriculturaleconomy. This may be a model for similar projects in otherWest African countries.36．The Sahel zone is an area which ___.A. is covered with sad and grassB. has a long historyC. occupies much of South NigeriaD. belongs to Sudan答案：a37. What is the situation about thedesertification in Africa?A. The deserts are replaced withgrasslandsB. The deserts are expandingC. the deserts are moving northwardsD. the deserts are being deserted答案：b38. The word “deteriorated ” in paragraph2 means ___.A. deepenedB. sufferedC. slippedD. worsened答案：d39. What is the root causeof desertification?A. poor farmingB. overpopulationC. radical climate changeD. disappearance of rare plant species答案：a40. In order to prevent desertification,the author proposes ___.A. making good use of international aidsB. developing a sustainableagricultural economyC. gaining international supportD. converting agricultural land intoforest答案：b第三篇OlderVolcanic EruptionsVolcanoes were more destructive in ancient history, not because theywere bigger，but because the carbon dioxide（二氧化碳）theyreleased wiped out life with greater ease.Paul Wignall from the University of Leeds was investigating the linkbetween volcanic eruptions and mass extinctions. Not all volcanic eruptionskilled off large numbers of animals, but all the mass extinctions over the past300 million years coincided with huge formations of volcanic rock. To hissurprise, the older the massive volcanic eruptions were, the more damage theyseemed to do. He calculatedthe "killing efficiency" for thesevolcanoes by comparing the proportion of life they killed off with the volumeof lava (熔岩) that they produced. He found that sizefor size, older eruptions were at least 10 times as effective at wiping outlife as their more recent rivalsThe Permian (二叠纪)extinction, for example, which happened 250 million years ago, is marked byfloods of volcanic rock in Siberia that cover an area roughly the size ofwestern Europe. Those volcanoes are thought to have pumped out about10gigatonnes (十亿吨) of carbon as carbon dioxide. The globalwarming that followed wiped out 80 percent of all marine genera (种类)at the time, and it took 5 million years for the planet to recover. Yet 60million years ago, there was another huge amount of volcanic activity andglobal warming but no mass extindtion. Some animals did disappear but thingsreturned to normal within tens of thousands of years. "The most recentones hardly have an effect at all," Wignall says. He ignored theextinction which wiped out the dinosaurs (恐龙) 65million years ago, because many scientists believe it was primarily caused bythe impact of an asteroid (小行星). Hethinks that older volcanoes had more killing power because more recent lifeforms were better adapted to dealing with increased levels of CO2.Vincent Courtillot, director of the Paris Geoophysical Institute in France,says that Wignall's idea is provocative. But he says it is incredibly hard todo these sorts of calculations. He points out that the killing power ofvolcanic eruptions depends on how long they lasted. And it is impossible totell whether the huge blasts lasted for thousandsor millions of years. He also adds that itis difficult to estimate how much lava prehistoric volcanoes produced, and thatlava volume may not necessarily correspond to carbon dioxide emissions.41.Older volcanic eruptions did moredamage than more recent ones becauseA. older volcanoes were brighter.B. carbon dioxide made the earth muchwarmerC. older volcanoes were hotterD. carbon dioxide killed off life moreeasily答案：d42. Wignall calculated the killing powerof those older volcanic eruptions byA. estimating how long they lastedB. counting the dinosaurs they killedC. comparing the proportion of lifekilled with the volume of lava producedD. studying the chemical composition oflava答案：c43. When did dinosaurs become extinct?A. 300 million years ago.B. 250 million years agoC. 65 million years agoD. 60 million years ago答案：c44.

These are seemingly simple activities that the majority of us don’t question. _____(46) The team of researchers from the U. S., England, Japan and Portugal investigated the behavior of modern-day chimpanzees as they competed for food resources，in an effort to understand what ecological settings would lead a large ape —one that resembles the 6 million-year old ancestor we shared in common with living chimpanzees —to walk on two legs."These chimpanzees provide a model of the ecological conditions under which our earliest ancestors might have begun walking on two legs", said Dr. Richmond.The research findings suggest that chimpanzees switch to moving on two limbs instead of four in situations where they need to monopolize a resource._____(47)Over time, intense bursts of bipedal activity may have led to anatomical changes that in turn became the subject of natural selection where competition for food or other resources was strong.Two studies were conducted by the team in Guinea. The first study was conducted by the team in Kyoto University's "outdoor laboratory" in a natural clearing in Bossou Forest. _____(48)The chimpanzees' behavior was monitored in three situations: when only oil palm nuts were available, when a small number of coula nuts were available，and when coula nuts were the majority available resource.When the rare coula nuts were available only in small numbers, the chimpanzeestransported more at one time. Similarly, when coula nuts were the majority resource, the chimpanzees ignored the oil palm nuts altogether. _____(49)In such high-competition settings，the frequency of cases in which the chimpanzees started moving on two legs increased by a factor of four. Not only was it obvious that bipedal movement allowed them to carry more of this precious resource, but also that they were actively trying to move as much as they could in one go by using everything available-even their mouths.The second study, by Kimberley Hockings of Oxford Brookes University, was a 14-month study of Bossou chimpanzees crop-raiding, a situation in which they have to compete for rare and unpredictable Resources. _____(50)46.【题干】_____【选项】A.Standing on two legs allows them to carry much more at one time because it frees up their hands.B.But an international team of researchers, including Dr. Richmond from GW's Columbian College of Arts and Sciences，have discovered that human walking upright, may have originated millions of years ago as an adaptation to carrying scarce, high- quality resources.C.Here, 35 percent of the chimpanzees activity involved some sort of bipedal movement, and once again, this behavior appeared to be linked to a clear attempt to carry as much as possible at one time.D.XXXXXXE.Researchers allowed the wild chimpanzees access to different combinations of two different types of nut —the oil palm nut，which is naturally widely available, and the

He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide. The global warming that followed wiped out 80 per cent of all marine genera at the time, and it took 5 million years for the planet to recover. Yet 60 million years ago, there was another huge amount of volcanic activity and global warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years. "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.Vincent Courtillot, director of the Paris Geophysical. Institute in France, says that Wignall‟s idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they lasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years. He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide emissions.2.阅读（15分）Black Holes TriggerScientists have long understood that supermassive black holes weighing millions or billions of suns can tear apart stars that come too close.The black hotels gravity pulls harder on the nearest part of the star，an imbalance that pulls the star apart over a period of minutes or hours，once it gets close enough.Scientists say this Uneven pulling is not the only hazard facing the star.The strain of these unbalanced forces can also trigger a nuclear explosion powerful enough to destroy the star from within.Matthieu Brassart and Jean-Pierre Luminet of the Observatoire de Paris in Meudon，France1，carried out computer simulations of the final moments of such an unfortunate star…s life，as it veered towards a supermassive black hole.When the star gets close enough，the uneven forces flatten it into a pancake shape.Some previous studies had suggested this flattening would increase the density and temperature inside the star enough to trigger intense nuclear reactions that would tear it apart.But other studies had suggested that the picture would be complicated by shock waves generated during the flattening process and that no nuclear explosion should occur.The new simulations investigated the effects of shock waves in detail，and found that even when their effects are included，the conditions favor a nu clear explosion.“There will be an explosion of the star — it will be completely destroyed，” Brassart says. Although the explosion obliterates the star，it saves some of the star…s matter from beingdevoured by the black hole.The explosion is powerful enough to hurl much of the star‟s matter out of the black hole…s reach，he says.The devouring of stars by black holes may already have been observed，although at a much later stage.It is thought that several months after the event that rips the star apart，its matter starts swirling into the hole itself.It heats up as it does so，releasing ultraviolet light and X-rays.If stars disrupted near black holes really do explode，then they could in principle allow these events to be detected at a much earlier stage，says Jules Hatpern of Columbia University in New York，US2.“It may make it possible to see the disruption of that star immediately if it gets hot enough，” he says.Brassart agrees.“Perhaps it can be observed in the X-rays and gamma rays，but it…s something tha t needs to be more studied，” he says.Supernova researcher Chris Fryer of the Los Alamos National Laboratory in Los Alamos，New Mexico，US3，says the deaths of these stars are difficult to simulate，and he is not sure whether the researchers have proven their case that they explode in the process.3.阅读（12分）Researchers Discover Why Humans Began WalkingUpright研究人员发现为何人类开始直立行走Most of us walk and carry items in our hands every day. These are seemingly simple activities that the majority of us don’t question.But an international team of researchers, including Dr. Richmond from GW's Columbian College of Arts and Sciences，have discovered that human walking upright, may have originated millions of years ago as an adaptation to carrying scarce, high- quality resources. The team of researchers from the U. S., England, Japan and Portugal investigated the behavior of modern-day chimpanzees as they competed for food resources，in an effort to understand what ecological settings would lead a large ape —one that resembles the 6 million-year old ancestor we shared in common with living chimpanzees —to walk on two legs.我们大多数人每天行走并且用手携带东西。

）(10分, 每空2分)The potential of the field produced by a system of charges equals the algebraic sum of the potentials produced by each of the charges . .Whereas the field strengths are added in the superposition of the field, the potentials are added . This is why it is usually much to calculate the potential than the electic field strengths.The work on a charge by the forces of a field equals the of the magnitude of charge and the difference between the potentails at the initial and final points.五.Tell whether the following statements are true(T) orfalse(F) according to the passage.（根据上文的内容判断下列句子的正误）（10分,每题2分）The object of the molecular-kinetic theory is to interpret the properties of bodies that are directly observed in experimental (pressure, temperature, etc.) as the summary result of the action of molecules. It uses the satistical method and is interested not in the motion of separate molecules, but only in average quantities characterizing the motion of an enormous combination of particles.Thermodynamics also studies various properties of bodies and changes in the state of a substance. Unlike the moleculars-kinetic theroy, however, thermodynamics studies macroscopic properties of bodies and natural phenomena without being interested in their microscopic picture. Thermodynamics permits us to arrive at a considerate number ofconclusions on how processes go on without taking molecules and atoms into consideration and without treating the processes from a microscopic stand-point. Therodynamics is founded on several fundmental laws established as a result of generalizing a large amount of experimental facts.Consequently, the conclusions of the thermodynamics have a very general nature.1.The object of the molecular-kinetic theory is to explain the performance of bodies as the summary result of the action of molecules.

Unlike the moleculars-kinetic theroy, however, thermodynamics studies macroscopic properties of bodies and natural phenomena without being interested in their microscopic picture. Therodynamics is founded on several fundmental laws established as a result of generalizing a large amount of experimental facts.Consequently, the conclusions of the thermodynamics have a very general nature.2.The E lines of a point charge field are a collection of radial straight lines directed away from the charge if it is positive and toward it if it is negative. One end of each line is at the charge, and the other extends to infinity. Indeed, the total number of lines intersecting a spherical surface of arbitary radius r will equal the product of the density ofthe lines and the surface area of the sphere 24rπ. We have assumed that the density ofthe lines numerically equals ()()214E q rπε=. Hence, the number of lines is 0qε.This result signifies that the number of lines at any distance from a charge will be the same.。
