函数变量

A multivariable equality constraint condition is hidden in switching functions through different equivalent transformations.

通过将一个由设备状态信息确定的多变量等式约束条件，经不同的等价变换，隐含于开关函数中，建立一个新的故障诊断数学模型。

Secondly,the deterministic equivalence problem of theprobabilistic inequality is discussed,and the expression formula of thedeterministic equivalences for several commonly used probabilitydistributions,such as normal,exponent,uniform,β and Γ distributions etc.,are given for the linear function with respect to random variables,which solvesthe problem of the deterministic equivalence for the linear-function-class.

其次，本章讨论了概率不等式的确定性等价问题，就随机变量的线性函数类，给出了与几种常用的概率分布，如正态分布、指数分布、均匀分布、β分布、Γ分布等等，相关的确定性等价问题。

The revenue-sharing ratio is exogenous variable, which is decided by the upstream and downstream enterprises together.

零售商销售产品时采用静态定价策略，价格是内生变量，市场需求是随机的，并且是价格的乘法函数。

For the case of time series with exogenous variables, it is better to set up transmissibility function model.

对于带有输入变量的时间序列，一般需要建立传递函数模型。

When the target function not explicit analysis expression (for example produces with value table), or has time the integer request to the variable, with .

当指标函数没有明确的解析表达式，或者对变量有整数要求时，用表格法。

It transforms the primal problem into an ordinary optimization problem with an explicit dual function and simple constraints, with smaller size than primal constraints. It is convenient for engineering application.

该方法不仅给出了原问题显式形式的对偶函数，而且对偶变量的数目仅等于原问题部分约束的个数，原来的线性0-1规划问题被转化为只有简单约束的普通优化问题，极大地方便了工程应用。

An exponential function is one in which the variable appears in an exponent.

指数函数是指数中出现变量的函数。

The traditional virtual boundary integral expression is based on the extension of single layer potential, for the integral formulas related to single layer potential for parabolic problem, the numerical computation of the exponential integral function is unavoidable.

通常的虚边界积分公式是利用单层位势的延拓来建立虚边界元积分方程，但对带时间变量的单层位势，要涉及到指数积分函数的计算。

And established the mechanics model,optimization parameter model,optimization mathematics model for the elastic element of the extensometer,programs analysis file and optimization control file by using the ANSYS parameter design language.

解析设计方法：依据弹性元件的受力特点建立其力学模型，运用已成熟的力学理论，如薄板弯曲理论、梁弯曲理论、柱拉压理论、剪切理论等获得弹性体的应力应变的解析值，从而获得目标函数和状态变量的解析值。

The external static declaration is most often used for variables, but it can be applied to functions as well.

外部的static声明通常多用于变量，当然，它也可用于声明函数。
