变量范围

Two types of new Abel differential equation are structured by method of variation replacement, variation position transformation and compound function derivation law.

借助变量替换法、交换变量位置法及复合函数求导法则，构造出两类新的 Abel型微分方程，论证它们的可积性，提供可积的判据，从而推广有关文献的结论，扩大微分方程的可积范围。

Directly into a Seam component using bijection. A context behaves like a map, wherethe keys are the context variable names. You can add a context variable to the event

上下文的行为类似map，键是上下文变量名，你可以使用下列设置增加上下文变量到事件范围

When the Biot-Savart Law is used to compute the magnetic field of a linear current, the different, choice of the integral variables will give rise to two different expressions.

用毕奥-萨伐尔定律计算一段直线电流的磁场时，因为积分变量的选取不同，产生了两种不同的表达式，在对积分变量的取值范围作了分析与比较后，更新了有关教材中的表述方式。

It was pointed out that the defective value of the affecting coefficient X provided by foreign software company should not used blindly.The operating vari ables have certain limitations and should not exceed these limits.

指 出在线工艺计算中不能盲目套用国外软件公司提供的影响系数X的缺省值；鲁棒多变量预估控制器操纵变量有一定的限制，不能超出范围。

The combinatorial and delimitative algorithm of engineering structure design with different discrete set and its software system is introduced in this paper.

引 言 离散变量优化设计是指在优化设计过程中，设计变量的取值不是在某一范围内连续变化而是只能取某些符合一定条件的离散值。

For example, exhaustive search through all subsets of variables to find the "best" subset (according to some score function), will be feasible only up to a point.

举例来说，详尽的搜索通过所有的子变量，以找到"最佳"变量子集在一定范围内将是可行的。

Inmodel is either a logical vector, whose length is the number of columns in X, or a vector of indices, whose values range from 1 to the number of columns in X, specifying the predictors that are included in the initial model. The default is to include no columns of X.

其中 X 为自变量矩阵， y 为因变量矩阵， inmodel 可以为一个逻辑向量，它的长度为 X 中列向量的个数或者说变量的个数；也可以一个序列向量，它的取值范围为1－ X 中列向量的个数，用来指定模型中的初始变量，默认值是没有选取任何 X 的列向量。

When a local variable declaration specifies var as the type and no type named var is in scope, the declaration is an implicitly typed local variable declaration.

当一个本地变量声明标示为var作为类型并且没有var类型名称在范围内，那么这个声明被视作隐式类型化的本地变量声明。

By analyzing the tested program, this paper presents the balance force method of test data generation, according to an input of the program, decide to remove variable scope and variable in the predicate processed with function minimum, an example is given in this paper.

文章通过对被测试程序的分析，提出了生成测试数据的平衡力法，对任意的输入变量，判断变量移动范围及进行谓词中变量的函数极小化，得到测试数据，并给出了具体实现方法。

In the chapter 5, during the optimization, the influence of search efficiency of choosing search variable is studied, and author proposes a kind of choice, which the positions of two exit points and the sagitta of the slip surface are taken as the search variable (the sagitta depends on the dynamic positions of two exit points of the slip surface), The examples show that the choice method decrease search region, improve the efficiency of searching, and has applying foreground.

在第五章中，探讨了搜索变量的选取对搜索效率的影响，对此作者提出以滑弧的两个端点位置以及它所组成的弓形高为搜索变量。实例表明，搜索变量的这种选取方法缩小了搜索范围，提高了搜索效率，有很好的应用前景。
