变量

Your PATH is an environment variable for your shell, and changing it depends on the shell you are using.

你的PATH变量是你SHELL中的一个环境变量，对它的改变取决于你所使用Shell。

It is obtained that a fuzzy mapping is convex if and only if the epigraph of this fuzzy mapping is a fuzzy set in R×E.

在此基础上，得到了一个实变量模糊数值映射是凸模糊映射的充分必要条件：这个实变量模糊数值映射的上方图是R×E中的一个凸集。

This is the var keyword, followed by the name of the variable, followed by its type, followed by an equals sign and an initial value for the variable.

这里有一个var关键字，后面跟着变量名字和变量的数据类型，再后面可以用"＝"符号来进行赋值。

If the name is followed by an equals sign and an expression, the expression serves as an initializer, as in char esc ='\\'; int i = 0; int limit = MAXLINE+1; float eps = 1.0e-5

在声明中，如果变量名的后面紧跟一个等号及一个表达式，该表达式就充当对变量进行初始化的初始化表达式。例如： char esc ='\\'； int i = 0； int limit = MAXLINE+1； float eps = 1.0e-5

But the equivalent computation of algebraic equation must be performed to get state variables corrections.

但是，这些算法中的大多数是在实时潮流计算的基础上，利用其中间结果和线性系统的叠加原理，直接求解出事故后的状态变量，都需要通过网络方程求解整个网络状态变量的增量，计算量较大，难于满足紧急状态下快速安全性评估的实时性要求，国内外一系列因静态潮流问题引起的大停电事故就是例证。

Half penalty method and optimism design of ten connecting bar mechanism of plunger slide in double action drawing press;2. The essential boundary condition is imposed by employing a penalty method .

将选择施加在"虚结构"控制点上的虚载荷作为形状优化的设计变量，并将它与无网格Galerkin法相结合来开展结构形状优化研究，采用罚函数法来施加边界条件，通过直接微分法建立了结构形状优化的离散型灵敏度分析算法，利用无网格法研究了节点坐标关于设计变量导数的计算。

So it is necessary to learn through the properties of the 2SLS estimator and suitable method in different cases.

所以在使用工具变量回归之前，有必要对工具变量回归估计的性质及各种情况下适用的方法有一个透彻的了解。

For the definition of two damage variables,damage variable and damage evolution equation are derived respectively.

针对两种损伤的定义，给出了损伤变量和损伤演化方程，同时用损伤力学定义了边坡的安全系数为极限损伤与最大损伤变量之比，并给出了应用算例。

An exogenous variable is a variable that is not explained by the model but rather is taken as given.

外生变量是模型本身不予以解释而是当成已知的变量。

This reduced form equation regresses the endogenous variable on all exogenous ones.

这个简约式方程将内生变量对所有的外生变量回归。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
