函数变量

The constructor of this class will take a reference to the io_service object and use it when initialising the timer_ member.

这个类的构造函数使用一个io_service对象的引用来初始化 timer_ 成员变量。

Finally, based on the studies above, the characteristics of pantograph/catenary are analyzed and the active pantograph is modeled. By using the linear quadratic optimal control law, the design objective is to minimize the performance index, which is a function of the state variables representing the pantographs dynamic characteristic and the active control force. The control system is designed considering the complete state feedback.

最后，在此基础上，分析了受电弓／接触网系统的工作特点，建立了受电弓主动控制系统的数学模型，利用线性二次型最优控制策略，以给定性能指标为最小值为设计目标，性能指标为表征受电弓动力学特性的状态变量和主动控制力的函数，考虑了完全状态反馈的情况，进行了控制系统的设计。

In many cases, compilers simply preallocate room in the function's stack area for the variable.

在多数情况下，编译器会简单的在函数的堆栈中为变量预留空间。

By employing the transformations of variables and functions, the exact bright soliton solution on a continuous-wave background is obtained in quadratures, and is discussed in detail. From the behavior of the exact solution in exponential control fiber system, the conclusion can be obtained that soliton in a proper fiber system can be compressed or broadened.

通过变量和函数变换得到方程的精确解为连续波背景下的亮孤子解，并对精确解在不同情况下的具体行为作了详细讨论，以指数分布控制系统为例说明：当选择适当的光纤控制参数时，孤子可以被压缩/展宽。

Response surface methodology was introduced into the cross sectional optimization of truss, in which the stress and displacement constraints were expressed as linear functions dependent on the reciprocals of cross sections.

把响应面方法引入桁架截面优化中，将应力和位移约束近似表达为桁架截面倒变量的线性函数。

Note that GDB can neither interpret nor modify relocations in this case, so branches and some initialized variables will appear to go to the wrong place.

注意在这种情况下，GDB 既不能转换，也不能修改重定向表，所以函数分支和一些已初始化的变量看起来是呆在不合适的地方。

The proposed method is successfully used to build Box-Jenkins's model of gas furnace.

但其目标函数只考虑了输人变量对模糊模型空间的

By defining a matrix function and introducing a free matrix U, the pole assignment constraint is relaxed, and the gradient σ2/U and σ2 σ2[V-1]/U are obtained. Thus robust design can be achieved by gradient method. Examples show that this method is very effective.

通过定义一矩阵函数并引入新的自由变量U，可放松极点配置的约束，并能系统的推导σ2/U及(σ2·σ2[V-1])/U，从而将鲁棒设计转化为无约束的梯度法寻优，实例说明，本文设计方法的效果很好。

Structural topology optimization is formulated in terms of the nodal variables on the level set function , which is converted to 0-1 variables by Heaviside function regularized by the sigmoid function.

利用有限元离散后的水平集函数的节点值作为拓扑设计变量来求解连续体拓扑优化问题。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
