金融体制、融资约束与投资——来自OECD的实证分析R．SemenovDepartment of Economics，University of Nijmegen，Nijmegen（荷兰内梅亨大学，经济学院）这篇论文考查了OECD的11个国家中现金流量对企业投资的影响.我们发现不同国家之间投资对企业内部可获取资金的敏感性具有显著差异,并且银企之间具有明显的紧密关系的国家的敏感性比银企之间具有公平关系的国家的低.同时，我们发现融资约束与整体金融发展指标不存在关系.我们的结论与资本市场信息和激励问题对企业投资具有重要作用这种观点一致，并且紧密的银企关系会减少这些问题从而增加企业获取外部融资的渠道。
一、引言各个国家的企业在显著不同的金融体制下运行。
金融发展水平的差别(例如，相对GDP的信用额度和相对GDP的相应股票市场的资本化程度），在所有者和管理者关系、企业和债权人的模式中，企业控制的市场活动水平可以很好地被记录.在完美资本市场,对于具有正的净现值投资机会的企业将一直获得资金。
然而，经济理论表明市场摩擦，诸如信息不对称和激励问题会使获得外部资本更加昂贵，并且具有盈利投资机会的企业不一定能够获取所需资本.这表明融资要素，例如内部产生资金数量、新债务和权益的可得性，共同决定了企业的投资决策.现今已经有大量考查外部资金可得性对投资决策的影响的实证资料（可参考，例如Fazzari（1998）、 Hoshi(1991)、 Chapman（1996）、Samuel(1998））.大多数研究结果表明金融变量例如现金流量有助于解释企业的投资水平。
这项研究结果解释表明企业投资受限于外部资金的可得性。
很多模型强调运行正常的金融中介和金融市场有助于改善信息不对称和交易成本，减缓不对称问题,从而促使储蓄资金投着长期和高回报的项目,并且提高资源的有效配置（参看Levine（1997)的评论文章）。
因而我们预期用于更加发达的金融体制的国家的企业将更容易获得外部融资.几位学者已经指出建立企业和金融中介机构可进一步缓解金融市场摩擦。

随着日益频繁增长，审计员听取了他们应该发表的一个效力于客户的内部控制制度建议的意见。
这一证明功能扩展的主张者迅速指出，目前已经有了实例如独立审计师的报告公开他们的客户的内部控制制度和一些政府机构的成效，包括一些空置中的美国证券和交易委员会，都需要一个报告。
这些证实类型的反对者公布了任何关于内部控制的有效性，他们认为，目前有显着性差异监管机构的报告要求和提出意见的内部控制将会误导公众。
本文综述了目前报告的做法，考虑到理想状态相关的危害的特点，并最后提出了一些在任何给与最后判决之前必要的予以回答的问题。
现状报告虽然审计员的报告中的一些情况提及了内部控制的性质，但作出的本质陈述还有很大不同的效应。
大型银行。
关于对内部控制的观点事实上出现在一些大型银行和看法发行的年度报告中。
有时这些意见是被董事会要求的。
例如，下面的主张出现在1969年年度报告的一个大型纽约银行中，作为第3款的独立会计师的标准短形式的报告：我们的审核工作包括评价有效性，大块的内部会计控制，其中还包括内部审计。
我们认为，在于程序的影响下，再加上银行内部审计工作人员所进行的审核，这些构成一个有效的系统的内部会计控制。
意见被提供给几个其他银行，但它们基本上引用的意见是一样的。
美国证券交易委员会的规定。
美国证券交易委员会表格X-17A-5，要求独立审计师作出某些有关的内部控制陈述，并必须在每年的大多数成员国家与每一个证券经纪或注册的交易商根据1934年证券交易法第15条进行交流时。

Subjective-well-being主观幸福感大学毕业论文外文文献翻译及原文
毕业设计（论文）外文文献翻译文献、资料中文题目：主观幸福感文献、资料英文题目：Subjective well-being文献、资料来源：文献、资料发表（出版）日期：院（部）：专业：班级：姓名：学号：指导教师：翻译日期： 2017.02.14Subjective well-being1 Subjective well-being and well-being simpliciterIn this section, I explore the relationship between subjective well-being and well-being simpliciter in the writings on subjective measures. I will argue that proponents of subjective measures of well-being disagree about the relationship between subjective well-being and well-being simpliciter: about whether subjective well-being constitutes well-being simpliciter or merely is a component of it.As my starting point, I take the concept of well-being, that is, what I have so far called well-being simpliciter: ―what we have when our lives are going well for us, when we are living lives that are not necessarily morally good, but good for us‖ (Tiberius, 2006, p. 493,italics in original). Let us call this the ―core‖ concept of well-being. There are many other terms that are used in the same sense, including ―a person‘s good, benefit, advantage, interest, prudential value, welfare, happiness, flourishing, eudaimonia, and utility‖ (Moore &Crisp, 1996, p. 599). Because the concept of well-being is intended to capture what is ultimately –and not just instrumentally –good for the individual, it is also supposed to capture that which we have reason to promote – as an end and not just as a means – both in our own lives and in the lives of others. As Thomas Scanlon puts it: It is commonly supposed that there is a simple notion of individual well-being that plays the following three roles. First, it serves as an important basis for the decisions of a single rational individual, at least for those decisions in which he or she alone is concerned (that is to say, in which moral obligations and concerns for others can be left aside). Second, it is what a concerned benefactor, such as a friend or parent, has reason to promote. Third, it is the basis on which an individual‘s interests are taken into account in moral argument (Scanlon, 1998, p. 93).3In particular, it is frequently assumed that well-being is one consideration or as some people would argue, the only consideration that should serve as an end, and not just a means for public policy. Here I will take it for granted that when proponents of subjective measures talk about such measures as representing well-being, they use the term in the core sense (Angner, 2009a, in press). First, as indicated above, subjective measures are often presented as alternatives to other measures of welfare or well-being; this would make little sense if, in fact, subjective measures were not intended to represent that which the other measures were designed to represent viz. welfare or well-being. Second, the proponents‘ concept of well-being plays the very same role as that played by the core concept: those who defend the use of subjective measures of wellbeing often emphasize that they think of well-being as that which is ultimately good for the individual, as that which is worth promoting in the life of others, and as a central (sometimes the only) ultimate goal for public policy (cf. Diener & Seligman, 2004, quoted above).Third, a number of proponents explicitly cite classical philosophical literature in enthusiastic agreement while signaling that they use ―well-being‖ and/or ―happiness‖ in the same sense as philosophers do (Kahneman, Wakker,&Sarin, 1997; Layard, 2005; Watson, 1930).Over the years, philosophers have tried to shed light on the concept of well-being by developing and defending various accounts, or conceptions of well-being. Here, I follow Parfit (1984, pp.493–502) in dividing such accounts into three main classes: mental state accounts, preference-satisfaction or desire-fulfillment accounts, and objective-list accounts.4 According to mental-state accounts, well-being is a ―mental state‖ or a ―state of mind.‖ Because these accounts all see welfare ―as having to enter our experience,‖ they are said to satisfy the experience requirement (Griffin, 1986, p. 13). Scanlon writes: ―Experiential theories hold that the quality of life ‗for the person who lives it‘ is completely determined by its experiential quality,‖ where ―experiential quality‖ refers to ―what it would be like to live it‖ (Scanlon, 1998, pp. 97, 99). On this view, then, subjectively felt experience is both necessary and sufficient for a person‘s well-being. According to desire-fulfillment or preference-satisfaction accounts, by contrast, a person is well off to the extent that her desires are fulfilled and/or her preferences are satisfied. Scanlon puts it this way:Desire theories reject the experience requirement and allow that a person‘s life can be made better and worse not only by changes in that person‘s states of consciousness but also by changes elsewhere in the world which fulfill that person‘spreferences (Scanlon, 1993, p. 186).Such accounts do not require that a person who is well off experience any feelings of happiness or satisfaction. What they do require is that her desires are fulfilled (or that her preferences are satisfied), which does not come down to the same thing. The two kinds of account described so far are frequently referred to as subjective accounts, because they describe a person‘s well-being as (at least partly) a function of his or her feelings, experiences, desires, and so on. According to so-called objective accounts, by contrast, a person‘s well-being does not depend on such subjective factors. On such accounts, ―certain things are good or bad for beings, independently in at least some cases of whether they are desired or whether they give rise to pleasurable experiences‖ (Chappell & Crisp, 1998,p. 553). Identifying the list of things that are good for people regardless of what they want is notoriously difficult, but one provisional list of such things includes ―moral goodness, rational activity, the development of one‘s abilities, having children and being a good parent, knowledge, and the awareness of true beauty‖ (Parfit, 1984,p. 499). Obviously, there are many versions of accounts of each kind.The tri-partite division permits us to capture a major difference between subjective measures of well-being, traditional economic welfare measures, and welfare indicators inspired by the capability approach. It has been noted elsewhere that traditional economic welfare measures are based on preference-satisfaction accounts of well-being (Angner, 2009a,b, in press; Harsanyi, 1982; Hausman & McPherson, 2006). This is evident, among other things, from the fact that welfare economists traditionally have defended their measures by showing that they are utility functions, that is, that they are indices of preference satisfaction. It has also been noted that measures inspired by the capability approach are based on objective-list accounts of well-being (Nussbaum, 2008; Sen, 1987). This is clear, among other things, from the assumption that certain things – in particular, having a large capability set – are thought to be good for a person regardless of whether those things would make the person happier, and of whether the person desires them.5Meanwhile, it is fairly obvious that many proponents of subjective measures think of well-being as a mental state. There is abundant evidence, for one thing, that they adhere to the experience requirement. In the literature on subjective measures,well-being is oftendescribed as a matter exclusively of individual subjective, hedonic, or affective experience. For example, David G. Myers quotes Madame de la Fayet te as saying: ―If one thinks that one is happy, that is enough to be happy,‖ and adds that ―like Madame de La Fayette, social scientists view well-being as a state of mind. Well-being, sometimes called ‗subjective well-being‘ to emphasize the point, is a pervasive sense that life is good‖ (Myers,1992, pp. 23, 27). Myers evidently takes well-being to be something thoroughly subjective; note, in particular, the use of the term ―subjective well-being‖ as synonymous with ―well-being.‖ The explicit reference to states of mind strongly suggests that what he has in mind is some type of mental-state account.Similarly, Ed Diener writes: ―The area of subjective well-being is subjective. [It] resides within the experience of the individual‖ (Diener, 1984, p. 543). Die ner and Eunkook Suh reinforce the point: Subjective well-being research is concerned with individuals‘ subjective experiences of their lives. The underlying assumption is that well-being can be defined by people‘s conscious experiences—in terms of hedonic feelings or cognitive satisfactions. The field is built on the presumption that to understand the individuals‘ experiential quality of well-being, it is appropriate to directly examine how a person feels about life in the context of his or her own standards (Diener & Suh, 1997, p. 191).Diener and Suh, like Myers and the authors to whom he refers, apparently use the term ―well-being‖ interchangeably with ―subjective well-being.‖ The fact that Diener and Suh argue that well-being is not only concerned with t he individual‘s subjective experiences, but defined by them, strongly suggests that they adhere to the experience requirement.Several authors emphasize the subjective character of well-being, as they use the term, by contrasting subjective measures with ―objective‖ ones, including social and economic indicators. Diener makes this point in the following way: Notably absent from definitions of SWB [subjective well-being] are necessary objective conditions such as health, comfort, virtue, or wealth. Although such conditions are seen as potential influences on SWB, they are not seen as an inherent and necessary part of it (Diener, 1984, p. 543).6This quote confirms that, in Diener‘s work, an individual‘s well-being is defined not by the objective circumstances in which she finds herself, but by her subjective experiences,though he allows the former to be causally responsible for the latter. Daniel Kahneman, who identifies well-being with happiness, adds that happiness ―is not to be confused with good fortune, which is an assessment of the circumstances of someone‘s life‖ (Kahneman,1999, p. 5). In Kahneman‘s view, it is possible to enjoy good fortune–presumably income, health, and so on –without being happy.Angus Campbell (1976), quoted in Diener (1984, p. 543), expands on this point. Campbell maintains: ―The gross national product, important as it undoubtedly is, is clearly not the ultimate touchstone against which the quantum of happiness in this country can be assessed‖ (Campbell, 1976, p. 117). He continues: If we are primarily concerned with describing the quality of life experience of the population, we will need measures different from those that are used to describe the objective circumstances in which people live. We will have to develop measures that go directly to the experience itself. These subjective measures will surely not have the precision of indicators that are expressed in number of dollars, units of time, or numbers of square feet, but they will have the great advantage of dealing directly with what it is we want to know, the individual‘s sense of well-being(Campbell, 1976, p. 118, italics in original).6 Quality of life, on Campbell‘s view, is a function of individuals‘ sense of well-being. If we want to study the quality of life, then,we need to study the individuals‘ experience of their lives, not the objective characteristics of their existence.These writings clearly give pride of place to subjectively experienced mental states. Indeed, the evidence suggests that these authors adopt the experience requirement and think of well-being as constituted by some subjectively experienced mental state. They are best understood as using the term ―subjective well-being‖ to denote the subjectively experienced mental state, so that well-being can be said to be constituted by subjective well-being. The notion that well-being is constituted by subjective well-being, by the way, explains the identification of ―subjective measures of well-being‖ and ―measures of subjective well-being.‖Others, however, appear to resist the view that well-being is constituted by subjective well-being alone (cf. Angner, in press). Increasingly frequently, it is suggested that subjectively experienced mental states constitute but one component of well-being. For example, Kahneman writes: Objective happiness is not proposed as a comprehensive concept of human well-being, but only as a significant constituent of it. Maximizing the。

Face of large-scale enterprise development, the need for a number of skills training in order to enable staff to achieve continuous business development. Therefore, the organization in order to raise labor productivity and personal satisfaction for professional, direct and effective for the organization of production and management services, the Government has implemented a variety of methods, types of organizations to carry out investment activities in education and training.U.S. economist and Nobel Laureate in Economics, Schultz found that simply from thenatural resources, physical capital and labor's point of view, can not explain all the reasons for increase in productivity, capital and wealth as a form of conversion of people's knowledge and abilities are decisive reasons for social progress. But it was not the acquisition cost, it needs to be formed through investment, training is an important investment in such a form..The level of training and developmentThe main groups of the organization of training, corporate training is to organize all the staff, staff positions held as a result of different orientation training with a variety of characteristics. In general, the main is divided into three categories: First, the decision-making level, and the other is management is the operation of three layers. The main contents of training and developmentOrganization of training content and structure is inherent in the specific form of training, thus the development of the company Training content, and organization must be the cause of progress, development strategies and goals, but sometimes in order to adapt to organizational changes in the external environment, but also training in the use of some emergency measures. Therefore, as the contents of the structure of training should be long-term development of the organization of production with the current combination of common training content into the enterprise.Period of training and developmentDivided by time period, training can be divided into long-term training and short-term training, long-term training of more general scheme, there is a strong purpose; by training, job training and can be divided into two full-time training; by the training system, organizations can be divided into the training system and training system for the two organizations, with the training system, including basic training, the applicability of training, day-to-day training, individual training and training objectives; the training system organizations, educational institutions, if divided, can be divided into for three categories: full-time college and the recognition of higher education institutions, local governments and administrative departments of education and training institutions, the use of community resources to schools.Source of funding for training and developmentOrganization of training funds mainly come from two ways: First, the source of the organization, mainly referring to organizations and staff training costs assessed; second is the raising of funds, first of all by the Government through taxes levied training, and then by the state organizations, social enterprises to co-ordinate the funding sponsorship.The economic benefits of training and developmentAs the organization and implementation of staff training to improve skills and to mobilize the enthusiasm of the production, so under the same conditions of employees to create more effective. The increase in the efficiency, can be used in two ways: direct and indirect calculation method of calculation.In the course of training, trainees should pay attention to the learning curve and information feedback, trainees listen to timely information that can help organizations improve the effectiveness of future training, to reduce unnecessary expenditures.In the training market, there are different styles of lecturers, there are different types of courses, some courses are developed by their own lecturers, some courses are foreign agents, and some courses are designed by companies. Training curriculum design is the first step in the design of different ways to use the curriculum, lecturers say is different, the final results of the training are different. Determines the script as a drama, the curriculum design is the first step in training, but also determines the effectiveness of courses.The cost of trainingEducation and training primarily on the basis of the level of information as well as the size of, the higher the level of information and larger, then the lower cost.Effective cost control is in fierce competition in the market of the basic elements of success. However, the absolute cost control is not just the cost of compression, the need to establish a scientific and reasonable cost analysis and control system that allows business managers have a clear framework for the company's costs, profitability in the right direction and decision-making, internal decision-making enterprises key support to radically improve the situation of the cost of doing business and thus truly effective cost control.8 kinds of employee training forms1, the teaching method: the training of the traditional way to use up the advantage of convenient, easy to control the whole process of training. The disadvantage is that a one-way transmission of information, poor feedback effects. Some of these notions are often used for training knowledge.2, audio-visual technology law: adoption of modern audio-visual technology (such as projectors, DVD, VCR and other tools), training of staff. Advantage of the use of visual and auditory perception of the way of clear-cut intuitive. However, feedback from students and practice less, and the cost of production and the purchase of a high content of easily outdated. It is used for business profiles, to impart training skills, conceptual knowledge can also be used for training.3, to discuss the law: In accordance with the complexity and operation cost of the procedure can be divided into the general panel discussions and seminars in two ways. Lectures, seminars and more in the main, or after the half-way to allow students and lecturers communicate. Advantage of multi-directional transmission of information, compared with the teaching of good feedback effects, but higher cost. The panel discussion is characterized by law, when the exchange of information for multi-directional transmission, the participation of students with high, low-cost. Used for the consolidation of knowledge, analysis of the training of students, problem-solving skills and the ability of human interaction, but the training of teachers on the use of the higher.4, case study method: the training of clients, through to the relevant background information, to find a suitable solution. The use of low-cost, effective feedback can be an effective analysis of the training of students problem-solving abilities. In addition, training in recent years studies have shown that the case, discussion can also be used for the training of knowledge category, and better.5, role-playing method: training grant to train teachers in the work of the design of which play a role in the training of teachers and other students in the students after performing the appropriate comments. As a result of multi-directional transmission of information, feedback effects, and practical, and low-cost, and thus more capacity forhuman relations training.6, self-learning method: This approach is more suitable for the general concept of knowledge, with emphasis on adult learning as a result of experience and understanding of the properties, so that a certain learning ability and self-conscious students is both economical and practical approach, but this method There are also deficiencies in poor supervision.7, group interaction law: also known as sensitivity training. This method is mainly applicable to the management of interpersonal and communication training. Training to enable trainees to experience activities to enhance their ability to deal with interpersonal relationships. The advantage is improved interpersonal relationships and communication skills, but its effects depend on the level of teacher training.8, Network Training Act: is a new type of computer network information on training methods, greater input. However, due to the use of flexible and distributed learning in line with new trends, focus on training students to save time and costs. Large amount of information in this way, new knowledge and new delivery concepts have obvious advantages, it is more suitable for adult learning. Therefore, for the strength of the popular business, training and development is an inevitable trend.The classification of training methods1. Smile Training: to serve the people, through a variety of special events, a speech full of passion, as well as recognition of participants, so that participants feel that the training process very interesting.2. Hands-On Training: First of all new workers need to perform their work after the observation, and then, through long experience with those who mentor or work colleagues together, to digest, absorb and purpose of the skills.3. Instrument Training: Through a standardized, there is no organization or organizations for the work of the evaluation tools tailored to obtain the relevant skills and their knowledge and information.4. Objective--Based Instuction: including a structured, guiding the training design, the focus is to better the implementation of a work, the incumbent must learn the specific knowledge and skills.。

程序员必须掌握与网络有关的大量细节，有时甚至要对硬件有深刻的认识。
一般地，我们需要理解连网协议中不同的“层”（Layer）。

这是一项令人痛苦的工作。
但是，连网本身的概念并不是很难。
我们想获得位于其他地方某台机器上的信息，并把它们移到这儿；或者相反。

A RESEARCH ON DATA PROCESSING MODEL OF GPS DAMDEFORMATION MONITORING NETWORKAbstract: Considering the particularity of the GPS dam deformation monitoring network, a data processing model based on the station orthogonal coordinate system for three-dimension GPS dam deformation monitoring network, was put forward. Also, a mathematical model of using the clustering analysis method in fuzzy mathematics to test the relative stability of quasi-stable points(or datum marks) was successfully brought forward. The adjustment method during the course of data processing was quasi-stable adjustment. At last, a software system of three-dimension GPS dam deformation monitoring network was designed and opened up with the help of Visual Basic Language. With three periods o'bservation data from the GPS deformation monitoring network of a dam, an adjustment calculation was done by the software.The calculation result shows that the mathematical models can be more suitable for the data processing in GPS dam deformation monitoring network.Key words: GPS, Dam deformation monitoring, Quasi-stable adjustment, Clustering analysis 1.IntroductionWGS-84 coordinate system is generally used in GPS. But local or independent coordinate systems are usually chosen in dam deformation monitoring networks for their small areas. During the course of past data processing, the adjustment under WGS-84 coordinate system forindependent networks or networks with several fixed points is often firstly made. Then, the transformation from WGS-84 coordinate system tolocal(or independent) coordinate systems is done. For GPS deformation monitoring networks with repetitive observation data, the obvious change of datum marks coordinates under the two different coordinate systems can be brought by the tiny deformation of datum marks among different periods of observation. And the greater error can be made during the coordinate transformation. If a local Gauss coordinate system is chosen, the projection distortions can also be produced by the transformation itself. For the reasons above, the station orthogonal coordinate system is chosen as the reference coordinate system for data processing of GPS dam deformation networks. And the mathematical model is put forward and deduced.2.Data processing model based on the station orthogonal coordinate system for three-dimension GPS deformation monitoring networks2.1 Coordinate systemThe station orthogonal coordinate system is a left-hand coordinate system. Its origin is set at one of the GPS monitoring points. The E(X) axis points at the meridian passing the origin. It is on the tangent plane of the origin. And the right north is taken as forward direction. The H(Z) axis is on thenormal line of WGS-84 ellipsoid at the point and takes outward as forward directi on . The E(Y) axis is also on the tangent pla ne of the origi n and uses east for forward directi on.If the positi on vector of the stati on orthogo nal coord in ate system origi nr TP o in WGS-84 is expressed as o 二X0 Y 0 Z o , according to the geodetic latitude and Iongitude ( B° , L。

They are baseli ne calculati on and n etwork adjustme nt. The baseli ne vectors in WGS-84 can be firstly got using baseline calculation. Secondly, the baseline vector transformation from WGS-84 to the station orthogonal coordinate system can be done with (3). At last, the adjustment of GPS deformation monitoring networks in the station orthogonal coordinate system can be successfully finished.2.2 Adjustment method and mathematical modelDeformation monitoring networks usually require higher precision. And if several fixed points are adopted for datum, the observation precision can be greatly reduced, because the known dataprecision is o'fte s n lower than the required precision and the beginning points ' displacement ca make annexe effect to observation data especially during the course of repetitive observation. So the classical adjustment method, which has some given points, is generally not used. But it is important to choose the reference points with stable physical status as datum of deformation monitoring networks. Considering the above two cases, the quasi-stable adjustment can be employed to make the more stable unknown data( the coordinates of relatively stable points away from the dam) match their stable values. Then, there are no distortion of surveying result and relatively stable datum. And the goal to monitor the deformation can be reached well. The adjustment model of GPS rank-deficient networks can be written asV=AX-LT. , (4)S(L)二阮piWith the least square method, the normal equation is expressed asNX二W (5)T Twhere N equals A PA and W equals A PLAnd the equati on can be got as followsR(N)=R(A)=r where A denotes the rank-deficient matrix whose rank-deficient number d is (n-r)」f S is a set of radical of zero space N(A) and R(S) deno tes d, the equation is written asAS=0 (6)When the inner product space is defined as (X,Y)=X T RY and R(R) >d, under the constraint condition X RX=min, the following equation can be gotS T RX=0 (7)With (5) and (7), the solution equation of weighting rank-deficientn etworks can be expressed asQ 亠-Q H RSVRQ^I XXWhere Q R de notes"、R*% H.When R is a diagonal matrix and its value is 1 or 0, (8) canbecome the model of quasi-stable adjustme nt. The S matrix can be give naccording to the condition AS=0. And the S matrix of GPS 3-dimensional deformati on mon itori ng n etworks is writte n as10 0 loo 1 o o-s z = 0)0010 ……oio ⑼ooi ooi o o 12.3 Mathematical model of calculat ing quasistable poi nts ' relative stability with clusteri ng an alysis For GPS dam deformati on mon itori ng n etworks, the stability of datum marks must be firstly tested in the observati on data process ing. Though the relatively stable area is chose n for build ing datum marks whe n GPS dam deformati on mon itori ng n etworks are desig ned, the deformatio n of datum marks can come into being. Eve n if the quasi-stable adjustme nt method is used, the stability test n eeds to be made, too. The quasi-stable poin ts(quasi-stable points or datum marks in desig n scheme) with marked deformati on should be elim in ated. The mathematical model of calculati ng quasi-stable poin ts(or datum marks) relative stability with clustering analysis in fuzzy mathematics is put forward to en sure the stable quasi-stable points(or datum marks) in GPS observation data processing. One characteristic of quasi-stable adjustme nt is that the correcti on value V of observati on data after adjustme nt is in variable. So the adjusted value L of observati on data is also in variable. And it is show n that the n etwork shape after adjustme nt is un cha nged. The observati on data of GPS n etworks adjustme nt is baseli ne vectors(coord in ate differe nces in 3 coord in ate axis directi on s).Then, after the quasi-stable adjustme nt of two periods of observati on data,the differe nces of coord in ate differe nces of two ran dom quasi-stable poi nts in 3coord in ate axis directi ons betwee n the two periods areinvariable. So, these values can ' t be changed with differces .cAod work can be finished once for ado toavoid the trouble of some methods calculat ing step by step.匸 an df denote the coord in ate differe nces of two ran dom quasi-stable points (i and j)aftertwo periods ' seobati on1 data adjustme nt. is the differe nee of coord in ate differe nces betwee ntwo periods.

It is concluded that alarger a shouldhosen according to the operation rule in clustering analysis. And it canbe recommended that and 入 should use 5 %and 0 .1465respectively. 3.A computation example and result analysis The computation example was chosen from the GPS(14) in dex parameter 入 of clustering analysisepfasi-stable points relativedeformation monitoring network of some rock and soil gravity dam. There were 3 periods of observation data in total. The observation dates were Mar.4 to 7, Jun. 4 to 11, and Aug.31 to Sept.4 in 2001. There were 75 GPS monitoring points in this network. And 6 of the total were in the relatively stable area of the lower river of the dam. The other 69 points were at the dam body. All the monitoring points were built on observation piers and had compulsive centering equipment. And all the observation was finished by 6 Ashtech Z-Surveyor dual-frequency receivers. The periods of all the points were more than an hour. The baseline solution of GPS observation data was gained by the Ashtech associated software Solution 2.5. For every period, everyday observation data was processed singly. The periods of time with bad signals were first eliminated. If they were still not eligible, the observation data was deleted. Then, with everyday qualified baselines, the network adjustment was prepared. The baseline solution precision is listed in Tab.1.6 monitoring points in the relatively stable area of dam lower river banks were used as fixed in itial datum. And the adjustme nt with fixed poi nts was done. With the adjustme nt result being an alyzed, it was show n that the displacement among 6 initial points could reach about 2~3mm. And the monitoring points ' precision after the adjustment with 6 fixed points was 1~2 times larger tha n the precisi on using quasi-stable adjustme nt. The result also explained the displacement of initial points. Because fixed initial datum could react on observation data for compulsive fixing, the precisi on was bad. In order to test the stability of quasi-stable poin ts, the mathematical model of clusteri ng an alysis method was employed. It was found that the quasi-stable point KL3 in Y directi on was obviously differe nt from the other 5 points whe n the sec ond period of observatio n was compared with the first.And KL3 in Y and Z directions was distinctly differe nt from the others whe n the third was compared with the first.Then, KL3 was eliminated after integrating the clustering analysis result of the seco nd and the third periods. At last, KL1 KL2、KL7、KR1 and KR3 were take n as quasi-stable poin ts. Because there was no quasi-stable adjustme nt fun cti on in GPS associated software of GPS manu facturersdesig ned for GPS deformati on mon itori ng n etworks using VB programming Ianguage. It had the function of quasi-stable adjustment in the stati on orthog onal coord in ate system. With it, the three periods of observati on data were processed. Because there were too many points, on ly the adjusted 3-dime nsional coord in ate syn thetical precisi on in the stati on orthog onal coord in ate system was listed in Tab.2 below.It is show n in Tab.2 that the mea n square error(MSE) of pla ne coord in ates can reach 1 millimeter and the MSE of vertical coord in ates can reach 2 millimeters. And the precisi on can satisfy the comma nd of dam deformatio n mon itori ng en tirely.4. Con clusi onsThe stati on orthog onal coord in ate system is more suitable for the refere nee coord in ate system of GPS dam deformati on mon itori ng n etworks. The quasi-stable adjustme nt method is more suitable for the data process ing of GPS dam deformati on mon itori ng n etworks. The mathematical model of calculati ng quasistable poi nts ' relative stability with clustering analysis can be used for the stability analysis of fixed in itial datum marks in GPS deformati on mon itori ng n etworks and datum marks in n ormal deformatio n mon itori ng n etworks as settleme nt monitoringnetworks or survey triangulation andtrilateration networks. And the correctness and feasibility of the advanced model have been proved with a computation example.。
