( 3 ) in the third part , we use eles to analysis quantities relation among our provincial town and village ' s consuming structure , especially conduct careful research on marginal consuming propensity , demanding price and basic living need . then we lodge current main problems of our provincial consuming structure ( 3 )第三部分，我们采用扩展线性支出系统( eles )对我省城乡居民消费结构之间的数量关系进行分析，特别是对边际消费倾向、需求收入弹性、需求价格弹性和基本生活需求等方面做了仔细研究，并提出了目前我省消费结构存在主要问题。
The results of research reveals the variation disciplinarian and the affected factor , defines the factor limiting the urban regional development . all these offer scientific references for reasonable city planning , municipal building project planning , reasonable arrangement of land use , the confirmation of land use intensity and the improving land use benefit . and a series of methods we have explored can apply the practical manipulation of grading and assessing urban land , which contribute to enhance working efficiency , shorten the time of evaluation , enhance the updating of urban land price , establish a system of dynamic superviso ry control and examination , and enhance accuracy and objectivity of urban land - rated evaluation 再由球形检验和主成份分析、信度分析、多元回归分析的技术路线，逐层递深地解译影响城市地价的主要因素及相互数量关系，其研究结果揭示了城市地价的变化规律和影响因素、明确了限制城市区域发展的因素，为合理的城市规划，市政建设项目规划，合理安排土地用途，确定土地利用强度，提高土地利用效益等提供了科学依据，同时探索的系列化方法可直接应用于城市定级估价的实际操作中，有利于提高工作效率，缩短估价时间，提高城市地价的现势性，建立地价动态监控和测算系统，又可提高城市定级估价的准确度和客观性，在理论上、学术和实践上均有积极意义。
The main innovations of this dissertation are just as follows : firstly , mathematical model on the compensation mechanism of economizing on water is set with the theory of agent of information economics , quantitative boundary of compensation is defined , and quantitative relationship between the compensation input and the effect of economizing on water is revealed 本项研究主要有以下创新：其一，运用信息经济学中委托-代理理论建立了节水补偿机制的数学模型，确定了节水补偿的数量界限，揭示了节水补偿投入与节水效果之间的数量关系。
Up to now , because the setting - up of the hedonic price model needs to collect a large amount of data and carry on the extensive investigation , nobody process experiential research to study the quantitative relation between the housing characteristic and housing price at home through investigating buyer ' s partiality in location condition , building structure , neighborhood environment etc . how to apply the hedonic price theory to analyze the housing price of our country , structure the housing hedonic price model and study the urban housing market , that is exactly the problem that this dissertation attempts to solved 到目前为止，由于特征价格模型的建立需要收集大量的数据和进行较为广泛的调查，国内还没有人通过对住宅购买者在区位条件、建筑结构、邻里环境等方面的偏好进行调查，实证研究住宅特征和住宅价格之间的数量关系。如何把特征价格理论应用于我国的住宅价格分析，构建住宅特征价格模型研究城市的住宅市场，这正是本文试图解决的问题。
In the paper , computational sophistication is applied to compute the basic solution matrix of a sort of two - dimensional periodic differential equation which contains two parameters . the matrix makes it realizable to study the stability of two - dimensional periodic differential equation , here , the following is proved in the paper : only if a ( t ) , b ( t ) , c ( t ) , d ( t ) satisfy some quantity conditions , is exponentially asymptotically stable <中文摘要> =本文应用计算技巧，计算出一类含双参数的二维周期系统的基本解方阵，以这个基本解方阵为依据，研究二维周期系统的结构稳定性。所得结论是：只要之间满足一定的数量关系，则该系统指数型渐近稳定。
It can be seen from the following aspect ; when the learners met with such kinds of problems that need to be solved about the relationships of quality and space , he can managed to find a way to solve it using mathematics . when he accepts a new knowledge of mathematics , he can find out the usage value of this new knowledge 具体表现在：当学习者面临着与数量关系和空间关系有关的有待解决的问题时，能主动地从数学的角度，运用数学的思想方法寻求解决问题的策略；当接受一个新的数学知识时，又能主动探索这一新知识的实际应用价值。
A useful approach is : use the regression model based influencing factors of price - earnings ratio , including share of tradable shares , reveal the quantitative relationship between share of tradable shares and price - earning ratio , derive post - trade price - earnings ratio , obtain post - trade share price and then calculate the price of non - tradable shares 解决非流通股估价问题的有益方法是：运用市盈率影响因素回归模型的非流通股估价方法，通过包含流通股比例及其它影响因素在内的市盈率模型中所揭示的流通股比例与市盈率的数量关系，推导出全流通后的市盈率，进而得到全流通后的股价，并推算出非流通股价格。
People have to fix tri - catalytic equipment on urban automobiles against pollution of them , but tri - catalytic can lead to more serious heavy metal pollution , whereas people have not thought to control the amount of automobiles in aspect of relation between environmental capacity and the amount of automobiles 对城市机动车污染均采用被动的三元催化设备，三元催化剂对环境将可能产生更为严重的重金属二次污染问题，而没有考虑从环境容量与机动车数量关系角度去控制产生污染的机动车数量。
Design a kind of sub - optimum digital prefilter . through the simulation of timing recovery loop which is n ' t added prefilter and which is added prefilter , discuss the convergence characteristic and compare the relation between timing jitter and signal to noise ratio , the relation between timing jitter and noise bandwidth of loop , the relation between symbol error ratio and signal to noise ratio 通过对加预滤波器后的定时恢复环的仿真，讨论了环路的收敛情况，比较了所设计的数字预滤波器和无预滤波器时环路定时抖动与信噪比、定时抖动与环路噪声带宽、误码率与信噪比的数量关系，证实所设计的数字预滤波器对减少定时抖动非常有效。
Structure of hc is the essential property of the middle school mathematic education we grasp the middle school mathematic essential character from three sides : phenomenon and essence , processor and result , form and content , the middle school mathematics is the science searching the space form and number relation of real world , such that processor unionized with result , form unionized with content 3人文价值结构? ?中学数学教育本质特征我们从现象与本质、过程与结论、形式与内容三个不同侧面把握中学数学的本质特征，中学数学是研究现实世界人的空间形式与数量关系的科学，是过程与结论的统一，形式与内容的统一。
