Not only some economists' standpoint that the arrangement of the property rights is the nature of corporate governance, but also other economists' ones that they pay more attention to the design and enforcement of corporate governance mechanisms. The division hypothesis of corporate governance would conduceto comprehensive knowledge of corporate governance. Second, this thesis formalizes the ideas "the optimal shareholder structure of a firm is endogenously determined" proposed by Demsetz (1983) in a simple framework, which constitute the new rationale against the proposition "the more concentrated theshare, the more efficient the firm is" by Berle and means.

公司治理的分层假说将有助于我们形成对公司治理内涵全面的认识；（2）本文在一个简单的框架下形式化了Demsetz（1983）提出的最优股权结构内生决定的思想，为反驳Berle和means（1932）提出的"股权高度集中，企业的价值将最大"的命题提供了新的理论依据；（3）我们证明，公司治理机制的"整合"对降低投资者之间的利益冲突所导致的"第二类代理成本"具有重要作用。

Should this experience prove false and Israel actually repent, forgiveness and national life would be by no means hopeless; and therefore utterances like v. 4 and 14, however inconspicuous they may be in comparison with the denunciatory passages, are by no means to be overlooked, and certainly not to be held as spurious.

应这方面的经验证明，虚假和以色列，其实悔改，宽恕和国家生活会，绝非无望；因此，话语像五，四和第14条，但不显眼，他们可能会在比较与denunciatory通道，是决不被忽视，当然也不是将要举行的作为杂散。

And, as for artists themselves, it is by no means their interest to undeceive such judges, however conscious they may be of the very natural means by which the extraordinary powers were acquired; our art being intrinsically imitative, rejects this idea of inspiration more, perhaps, than any other.

然而，作为艺术家，他们自己往往对考证为什么或是谁建造的那些石雕决不感兴趣，却倾心于临摹成就这些艺术品的超凡能力。这就是说，我们的艺术并不是思想意念的灵感或其它东西，艺术就是固有的模仿。

Second, to replace the rationality that bereaves him by anther rationality, the result lies on the type of the object. Thirdly, he will persist in fighting while low cost. Fourth, eluding the rationality and validity by appealing to personal relation ,this means is influenced by the degree of familiarity. Finally, if the deprivation is rational without legality, except the first,second and fourth means, peasant will take law as a weapon sometimes, and the effect is attached with the balance between the law and tradition.

研究发现，纠纷中被合理且合法剥夺的农民，有四种应对策略可供选择：一是试图逃避合理性与合法性发挥作用的场域，但这要付出相当大的代价，因此并不常用；二是以其他的合理性来代替利益剥夺所依据的合理性，其效果受到不同层次的抗争对象影响；三是在违法的成本较小时采取对抗到底的策略；四是运用人情面子机制来消解利益剥夺的合理性、合法性，成功与否与对立双方关系的亲疏远近密切相关；如果是合理但非法的利益剥夺，这时除了第一、二和四种策略外，农民有时也会拿起法律武器，它的效果与法理之间的力量对比结果有关。

In this paper Ⅰ successfully applied these methods to fault diagnosis, and presenting some new innovative machinery fault diagnosis method; First Ⅰ present a new gear wornout fault diagnosis method, this method use the vibration signal's time-frequency attribute and instantaneous phase undulation to accurately detect gear's fault, and by comparing with the traditional frequency domain analysis method, this method reveals that many nonlinear and nonstationary characteristic exist in gear's vibration, this tell us that if we use frequency domain analysis method without pay attention to the signal's characteristic, we could get wrong diagnostic result; Then Ⅰ present a new bearing fault diagnosis method, this method use ATVFD and Hilbert transform to do envelop demodulation,Ⅰ analyze the envelop with time-frequency method and find out that this method is more accurate then traditional method.Ⅰ also explain that the modulation of the fault to the carrier wave may also be non-stationary and nonlinear; Finally Ⅰ present a cylinder pressure measurement method of diesel engine by means of vibration, cylinder pressure is an important parameter of diesel engine fault diagnosis, the pressure measuring is simplified a lot by this method,Ⅰ also use the ATVFD and time-frequency analysis to realize it.

本文中将上述理论方法成功地应用到故障诊断中去，提出了几点创新性的诊断方法；提出了一种齿轮磨损故障诊断的新方法，该方法利用振动信号能量的时频域分布特征与瞬时相位波动特征可以进行精确的齿轮故障诊断，并通过与传统的频域诊断方法的比较，揭示出齿轮振动中存在的明显的非线性与非平稳特征，说明了不加选择地利用频域分析方法进行齿轮故障诊断很可能会得到错误的诊断结果；提出了一种轴承故障诊断的新方法，该方法利用ATVFD分解与Hilbert变换进行包络解调，并对解调得到的包络信号进行时频域分析，可以实现更加准确轴承故障诊断，说明了故障对载波信号的调制往往也是非平稳与非线性的；提出了一种利用振动信号进行柴油机汽缸内压力检测的新方法，柴油机汽缸压力的变化是柴油机故障诊断的重要参数，利用振动方法可大大简化汽缸压力的检测过程，该方法也是综合利用ATVFD分解与时频域分析方法实现的。

运用&二人零和博弈理论&的相关知识，建立一个税务局－企业的博弈模型，在这个模型中，政府作为博弈规则的制定者，完全有能力通过制定相应的博弈规则，而使双方决策在纳什均衡时自己的利益最大化。我们用Mathematica4.1软件来帮助分析理解，寻找政府征税的最优决策，以期规避信息不对称、征税成本高等不利因素的影响。在不增加企业负担即不提高税率的情况下，分析给出政府征税的最优决策，以提高政府征税效率，增加税收收入。
