函数元素

The functionality of the random.choice function is given a sequence, return a random element of that sequence.

函数random.choice的用处就是根据指定序列，随机返回该序列中的一个元素。

A reasonably general solution are two functions For debugging it is very helpful to be able to look at individual objects.

一个合理的一般解决方法是定义两个函数：+能查看单个元素对于调试是很有帮助的。

However the calculation of invariants for coloured Petri nets is a hard work because the elements of coloured incidence matrix are not integers, but functions instead.

但是，着色Petri网的不变量求解却是一项非常困难的工作，因为它的关联矩阵的元素不再是整数而是函数。

For the condensed dynamic stiffness matrix in finite models which have finite number of freedom and any dynamic stifmess matrix of infinite system, the element of them is a transcendental function of eigenfrequency. And therefore transcendental eigenvalue problem is needed to be solved in order to get the natural frequency and modes of vibration.

对于有限自由度系统的缩聚动刚度矩阵和无限自由度系统的任何动刚度矩阵，其元素是频率的超越函数，因此求解结构固有频率及其振型归结为求解超越特征值问题。

Elements are always inserted in front of the position denoted by the iterator argument to inserter.

inserter 函数总是在它的迭代器实参所标明的位置前面插入新元素。

第一个版本的顶级函数返回对使您可以修改值的在堆栈顶部的元素的引用。

Here we obtain that the randomiza-tions of the element of the subspace〓of〓are the pointwisemultipliers of〓almost surely.Furthermore,the random Dirich-let type functions are studied by way of Lipschitz condition.

另外对随机Dirichlet型函数的研究借助了Lipschitz条件，结果表明〓的某子空间的元素的随机化在概率为1意义下满足q-Lipschitz条件。

Also, avoid using the list returned by map as an lvalue, as this will modify the elements of LIST.

同样，避免用map函数返回的列表作为等式左值，因为这也会改变LIST中的元素。

As an example, lets retrieve the one document with name=='mongo'. There are many ways to do it, including just calling next on the cursor (after checking for null, of course), or treating the cursor as an array and accessing the 0th element.

例如，我们可以通过很多种方式检索一个名称为'mongo'的document，包括在游标中调用next函数(当然，要验证完是否为null之后)，或者把游标看做一个数组然后访问数组的[0]下标元素。

Researches show that the proposed arithmetic has solved the problems of technique for ascertaining nonmembership functions of IFS effectively,who have the trait of fixing order according to different attributions.

研究表明，该算法可有效地解决元素依属性具有先后顺序特性的一类IFS非隶属度函数确定方法的问题。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
