查询词典 convergence behavior

The relationship between transient response and shape design variables is highly non-linear, and the behavior of feasible domains is often not good, which may cause convergence difficulties. In order to improve convergence speed of iteration process, some algorithms the feasible domains adjusting, the adaptive move limit, the approximate line search and the approximate reanalysis, are adopted.

For gas flow past cylinder, the characters of flow field in different Mach number and Knudsen number condition were investigated, and especially for low Knudsen number cases, the results were compared with calculating results of Euler's equation. It showed that they are correspondent by comparing the characters of bow shock and wake. The convergence rates of different high resolution and implicit schemes were also investigated. The convergence behavior of the implicit WENO scheme developed in this paper is better than others. For gas flow past NACA 0012 airfoil, the calculating results were compared with results of experiment. It showed that the results of WENO scheme are of higher accuracy for the case with angle of attack.

Firstly relied on the "Principal-Agent" theory, it will go through the microcosmic model analysis of corrupt behavior, including the avail analysis of "Defalcation corrupt behavior" and the equilibrium analysis of "Rent-seeking corrupt behavior", and then it will conclude some important factors which influence the corrupt behavior, such as the probability to be lighted, the salary of the officials, the degree and extent of the punishment and so on.Then it will go deep into the institutional analysis of the complicated corrupt phenomena. Relied on the institutional economics, this text will expound elaborate that during the compelling transformation of institutions, the structure of public power has an essential change. On the one hand, government has given up much public power; on the other hand, the cooperation mode between the government, the market and the society has not been perfected. So on account of the unbalance of public power structure, the disfigurement or blankness of the institutions was one of the vital institutional causes of the corruption.

首先以"委托——代理"理论为依托，对"贪污型腐败行为"和"寻租型腐败行为"进行微观的模型分析，通过对"贪污型腐败行为"的效用分析和"寻租型腐败行为"的均衡分析，推导出影响腐败行为的几个主要因素，如腐败的查处概率、政府官员的薪金、惩罚力度、个人的风险态度、租金的来源、市场主体的自主性、对行贿者的惩戒力度等等；接着对当前普遍而复杂的公共权力腐败现象进行深入的制度分析，运用制度经济学的理论，分析我国在强制性制度变迁过程中公共权力架构发生了本质的转变，政府在市场化的进程中一方面确实下放了很多公共权力，但另一方面市场和社会并没有充分发展起新的协作模式以弥补制度变迁过程中形成的制度缺陷或制度真空，因此，公共权力架构的失衡所形成的制度缺陷或制度空白成为了当前腐败蔓延的制度原因。

Finally, a light is a Behavioral Object, which means that it can have a behavior attached to it (some Virtools classes, such as classes that store internal data only, can not have behaviors attached to them). Since a light is also a Behavior Object, any behavior that can be applied to a Behavior Object can also be applied to a light.

最后，一个灯也是一个行为对象，意思是说它能拥有属于这个类的所有行为（一些Virtools类，例如存放在内部的数据都不属于它们）因为灯也是一个行为对象，任何能应用到行为对象的行为都可以应用到这个灯上。
