利用FDS课题组开发的多功能中子学程序系统VisualBUS1.0，针对该系统燃耗计算过程具有多变量和多目标函数复杂关系的特点，应用遗传算法对嬗变包层的锕系废料嬗变区的初装料量进行了优化处理，使其在一定的物理和工程参数约束下，指导嬗变区的装料份额取值，分析嬗变区的装料份额对锕系废料的年燃耗深度等参数的影响。

The financial governance is very important for corporate as an independent behavior subject and also interplays with the financial environment and individual characteristics. The financial behavior incentive mechanism is the dynamical mechanism in the selection of financial behavior.

由于企业财务行为是企业对理财环境刺激的反应，企业自身与理财环境都是影响企业财务行为选择的内生变量，都会对企业财务行为产生激励作用，因而企业财务行为激励机制可分为自我激励机制和外部激励机制，前者是企业自身对财务行为的自主的、内在的激励机制，后者是理财环境对财务行为的外在激励机制，这两者是相互影响的，因此应从这两个方面来完善我国企业的财务行为激励机制；财务行为约束机制是财务行为的制衡机制。

this paper basis on the current codes,taking axis compressive resistance concrete column bearing capacity formula as constraint condition., taking cost as objective function, taking reinforcement diameter and concrete strength grade as design variables, giving an optimization design, got the best basic parameters which satisfied application conditions,to provide better calculation for the axis compressive resistance concrete colum design.

本文以现行规范为依据，以混凝土强度理论推导出的轴心抗压混凝土柱的承载力计算公式作为约束条件，以造价为目标函数，以混凝土中的钢筋直径、混凝土强度等级为设计变量，对其进行优化设计得到了满足使用条件下的最优基本参数，为轴心受压混凝土柱的设计提供了较好的计算依据。

Otherwise, the control flow estimate makes no difference among processes which are congruent under α conversion by labeling restricted names and variables with stable names in the syntax of Mobile Safe Ambients.

在Mobile Safe Ambients演算进程的拓扑结构抽象表示基础上，通过识别可被激活的移动原语和通讯原语，计算系统运行的所有动态进程拓扑结构，并在文法规则中显示地标识约束名字和变量，使分析结果在α变换下保持不变。

This thesis also improves the algorithm of iterative calculation of direct kinematics on two aspects. One is to solve the "floating" problem, which is the change of the leg lengthes when nuts of ballscrews rotate around their own axises.

通过对几类关键受限变量——杆长、关节摆角、倾倒角和旋转角进行相关运动学计算，实现对它们的限位约束；同时，针对因滚珠丝杠螺母副引起的杆长随角度变化而&浮动&的特殊问题，对正向运动学迭代算法进行改进，加快了收敛的速度； 3。

In the 1970s and 1980s chartists had modest success in predicting currency markets because, one theory says, the strong role of central banks and treasuries in currency markets constrained the variables so that they could be described in relatively simple linear equations.

在二十世纪七十年代和八十年代，这些图表分析员们在货币市场的预测方面有了一点成功，这是因为，按照一种理论的说法，中央银行和财政部在货币市场中的强势角色约束了各种变量，这样一来，就可以用一种相对简单的线性方程来描述整个市场的表现。

A discussion is given on the possibility of the negative resistance component and its physical properties, set forth the relationship between the negative resistance component and negative impedance converter and applicatio
