In presented method, the correlated variables are transformed into uncorrelated variables equivalently, and the performance functions in the correlated variables space are transformed into those in the equivalent uncorrelated variables space, in which the reliability sensitivity of the system failure probability with respect to the distribution parameters of the uncorrelated variables can be solved by the moment method for the uncorrelated variables. Finally the equivalent relationship between the correlated variables and the uncorrelated variables, the chain rule for derivative are employed to obtain the reliability sensitivity of the system failure probability with respect to the means of the correlated variables.

Special attributes: func doc or doc is the function's documentation string, or None if unavailable; func name or name is the function's name; module is the name of the module the function was dened in, or None if unavailable; func defaults is a tuple containing default argument values for those arguments that have defaults, or None if no arguments have a default value; func code is the code object representing the compiled function body; func globals is the dictionary that holds the function's global variables — it denes the global namespace of the module in which the function was dened; func dict or dict contains the namespace supporting arbitrary function attributes; func closure is None or a tuple of cells that contain bindings for the function's free variables.

class function：类函数

这个关键字在C 上加上类变量上,则是类全局变量(在Delphi中好像只有类函数(class Function)也没有类变量吧?这个就不太清楚了). 虽说是类全局变量,但也可以作为是普通全局变量使用. 这个关键字加在C++的类成员函数上则声明一个类静态函数(Delphi则是class Function).

extern：外部变量

__interrupt void Interrupt 函数名(void)void 函数名(void)它与全局变量的区别是全局变量可以再说明为外部变量(extern) 被其它源文件使用而静态全程变量却不能再被说明为外部的只能被所在的源文件使用
