H robust controller is devised for the integrated mathematical models . computer simulations with matlab6 . 1 demonstrate that h2 / h output feedback controller of the active suspension system , based on nash equilibrium point , achieves a good balance between robust stability and suspension performance Matlab6 . 1进行仿真，仿真结果表明通过纳什均衡点设计出的h _ 2 h _输出反馈控制器能够使系统在保持鲁棒稳定性的前提下获得优化的动态性能指标。
On the other hand , there is the argument that market imperfections arising from market concentration , information disclosure and so on mean that , in practice , there is no perfect , textbook market ; and the market price can overshoot to the point where a financial meltdown threatens before the equilibrium price is found 另一方面，亦有人认为由于市场集中资料披露等原因引致市场存在不完善的地方，这即是说实际上是没有教科书所说完美的市场，市价可能会过度调整，甚至出现金融崩溃的威胁，然后才能达到均衡点。
In this thesis , the inviting & biding mechanism is analyzed and the feasibility and function of its operation is also conducted . under the framework of the analysis of the supply and demand of engineering insurance , the concept of security and economy is brought up : the district characteristics of the equilibrium on s / ' d curve is studied of large - scale engineering insurance . also , the optimal principle of insurance arrangement is brought up 论文对招投标机制运用于工程保险的承保环节进行了分析，阐述其运作的可行性和意义；通过对工程保险供给与需求的研究，提出了保险人和被保险人承保的安全性和经济性的概念，分析了大型工程保险供需曲线均衡点的区域特征，由此得出了保险方案的最优化原则以及在该原则指导下经保险双方动态选择后的最优保险方案。
Henceforth , many economists start study different ware spaces the price system influenced by different factor , discuss the existence of equilibrium point , because of the factor which influence the price more and more , the ware space also extend to infinite dimension from finite dimension . many mathematicians start prove under what conditions the equilibrium point exist , and discuss the algorithm of the equilibrium point , studying the convergence of the algorithm 此后，许多经济学家开始研究各种各样的商品空间，各种因素影响的价格体系，讨论均衡点的存在问题，由于影响价格的因素越来越多，商品空间也从有限维扩充到无穷维；许多数学工作者开始证明在什么条件下均衡点存在，并讨论均衡点的算法，研究算法的收敛性。
Have explained the merit of system quality of the administrative reconsideration , that is the reason of existing and its shortcoming and weakness , point out that the administrative reconsideration as the system that can conduct citizen ' s right simple , easily and rapidly , unsuitable to regard reducing efficiency as the cost to violate its existing reason and set up the excessively complicated procedure , so to find a balance between right and efficiency from system design becomes essential 阐述了行政复议的制度性优点即存在理由以及所具有的缺点或弱点，指出行政复议作为简易、迅速地救济公民权利的制度，不宜以降低效率为代价去违背其存在的理由而设置过度复杂的程序，因而要从制度设计上在公正与效率之间找到均衡点就成为至关重要的内容。
But the public have the different understand , one side is the propagandize to the audit is not correct , the public have exorbitant expectation , another side is the audit have many localization . the location have many reasons , for example the system of the audit and the economy condition to the audit 在法学界、会计学界对于审计制度的认识并不相同的情况下,注册会计师民事责任问题的解决成了各个利益团体之间利益均衡点的寻找,而不是责任标准的发现。尊重和了解会计行业的生存方式是解决注册会计师民事责任问题的前提。
On the other hand , there is the argument that market imperfections arising from market concentration , information disclosure and so on mean that , in practice , there is no perfect , textbook market ; and the market price can overshoot to the point where a financial meltdown threatens before the equilibrium price is found 另一方面，亦有人认为由于市场集中、资料披露等原因引致市场存在不完善的地方，这即是说实际上是没有教科书所说完美的市场，市价可能会过度调整，甚至出现金融崩溃的威胁，然后才能达到均衡点。
I have taken impotance to analyze the rallying point of famous product , concrete cost and capability of providing and guarantee in this artical , meanwhile , i have caculated the quantity of concrete needed for the year and got the regression equation with the historic data for drilling footage of eight years and the consuming quantity of oilwell cement by the method of linear regression , and it has very significance for the making of stock contract and the plan of concrete production , i have analyzed the physical distribution of oilwell cement by the transpotation flex and the advantage or disadvantage between direct distribution and distribution to store in this artical , and i have tried to find the balance point of the two distribution ways by the ecnomic analysis and pointd out the conception of economic semidiameter , and come to the conclusion of direct distribution , distribution to store , and subarea of distribution to store at last 本文对油井水泥供应商在品牌号召力、水泥成本、供应保障能力等方面进行了详尽分析,并对供应商进行了能力排序;用线性回归方法从八年钻井进尺与油井水泥消耗量的历史数据推算了当年度油井水泥需求量,得出了回归方程,这对于油井水泥采购合同的制订、水泥供应商生产计划的制订具有相当重要的意义;从运输弹性分析出发对油井水泥物流配送进行了研究,对直达配送、入库配送的优缺点进行了详细的分析,在经济分析的基础上力求找到两种配送方式的均衡点,并提出了经济半径的概念,得出了直达配送、入库配送、入库分区距离等几项结论。
3 . in the paper , we consider gordon theory of a class of single - species ecological systems with periodic coefficients on open - access fishery , and set up the ordinary economic equilibrium conditions of the single - species and get globally asymptotically stable economic equilibrium ; the over - exploitation of the system and the modification on economic equilibrium conditions by opportunity cost are investigated 考虑了一类具周期系数的单种群生态系统的gordon理论，建立了单种群系统最为普遍的经济均衡条件，从而找到了全局渐近稳定性的经济均衡点；并对系统因捕获造成的过度开发，以及对gordon经济均衡条件的改进作了相应研究。
