查询词典 variable cost

Starting from symmetry properties of equation and considering the variable coefficient of the equation as a new dependent variable,a new general method to solve variable coefficient equation is proposed.

将非线性方程的变系数看作与实际物理场具有相等地位的新变量，利用普遍的经典李群方法可以求解某些特殊类型的变系数方程，其解由相应的常系数方程的解表示。

Is the address of a variable or a variable in which the address of another variable is stored.

指针是一个变量的地址或者是存储了另一个变量地址的变量。

C variables in the positioning of the compiler things, as long as the definition of beginners variable and the variable scope, Compiler put a fixed address to this variable.

在C中变量的定位是编译器的事情，初学者只要定义变量和变量的作用域，编译器就把把一个固定地址给这个变量。

C# basically has kind of two kinds of data, value kind and cite type, when value kind is delivering variable, those who deliver is the value of data, and cite when the type is delivering variable, the variable address that pass.?

C#主要有两种数据类型，值类型和引用类型，值类型在传递变量的时候，传递的是数据的值，而引用类型在传递变量的时候，传的变量的地址。？

If your library needs to get at an external variable (external to the library, not just to one of the modules within it), you must use the ..got type to get at it. The ..got type, instead of giving you the offset from the GOT base to the variable, gives you the offset from the GOT base to a GOT entry containing the address of the variable. The linker will set up this GOT entry when it builds the library, and the dynamic linker will place the correct address in it at load time.

如果你的库需要得到一个外部变量(对库来说是外部的，并不是对它所在的一个模块)，你必须使用。。got类型得到它。。。got类型，并不给你从GOT基地址到变量的偏移，而给你的是从GOT基地址到一个含有这个变量地址的GOT入口的偏移，连接器会在构建库时设置这个GOT入口，动态连接器会在载入时在这个入口放上正确的地址。

The caller must provide the address of the variable to be set (technically a pointer to the variable), and the called function must declare the parameter to be a pointer and access the variable indirectly through it.

这种情况下，调用者需要向被调用函数提供待设置值的变量的地址(从技术角度看，地址就是指向变量的指针)，而被调用函数则需要将对应的参数声明为指针类型，并通过它间接访问变量。

However, even with the crummy variable name, the declaration bool x; communicates a great deal of information to the programmer about the purpose of variable x and how variable x is likely to be used in expressions.

然而，即使是相当简单的变量名，声明 bool x，也向程序员传达了大量的信息，关于变量 x 的目的以及 x 在表达式中可能的用法。

Applied with space vector diagram, a novel method for analyzing the control law and current controllability of variable structure control is proposed The detail discussions of parameter design, robustness and stability analysis are also made Furthermore, based on modeling the DC capacitor voltage control subsystem, a kind of fuzzy voltage controller is proposed, which results in good control performance In order to reduce the chattering of variable structure, a novel control scheme----fuzzy variable structure control is proposed in the fifth chapter.

针对变结构控制在应用中出现的抖振问题，本文第5章应用趋近率控制与模糊控制的有机结合，提出了模糊变结构控制策略，并应用空间矢量分析法揭示了其控制机理。

The method employs characteristic values such as hinge node voltage at dividing place between the large district grid and the provincial grid and tie line reactive power and so on as a coordinated variable of wattless control of the large district grid and the provincial grid, and real-timely calculates an optimal set value of the coordinated variable in the large district grid which is sent down to the provincial grid via wide area communication. In the coordinated control of the provincial grid, the method can not only realize the control object of original grid, but can also realtimely track the optimal set value of the coordinated variable given by the large district grid.

本方法选择大区电网与省级电网分界处枢纽节点电压和联络线无功等特征量作为大区电网与省级电网无功控制的协调变量，通过大区电网的无功优化，实时计算出大区电网中协调变量的最优设定值，该设定值通过广域通信下发到省级电网，在省级电网的协调控制中，除了满足本级电网的控制目标外，还实时跟踪由大区电网给出的协调变量的最优设定值。

The result of genetic analysis conveyed that in partial sequences of mtDNA Cyt b gene there were no variable sites between the eggs and Japanese halfbeak, and the genetic distance between them was 0, however, many variable sites between the eggs and the other fishes of Beloniformes were exised, the variable rate was 18.72-21.3％, and the genetic distance between them were 21.9-26.4％.

遗传学分析结果显示：鱼卵与沙氏下鱵鱼mtDNA Cyt b基因片段序列之间无差异，遗传距离为0，而与其它颌针鱼目鱼类序列间差异达18.72～21.3％，遗传距离在21.9～26.4％之间。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
