即不管负载的无功功率如何变化，总要使二者之和为常数，这个常数等于电容器组发出的容性无功功率的数值，使取自电网的无功功率为常数或为0，即：=常数（或0），最终使得电网的功率因数保持在设定值，电压几乎不波动，从而达到无功补偿的目的，以抑制负载波动所造成的系统电压波动和闪变。

A sound style rule bars the instructions of a program from using any numerical or textual constant directly; instead, they rely on symbolic names, and the actual values only appear in a constant definition (constant in Pascal or Ada, preprocessor macros in C, PARAMETER in Fortran 77, constant attributes in the notation of this book).

Aogosoft.com站上一网友写的程序，专门用来转换资源中的常量定义到汇编的INC文件格式使用Win32Asm编程的过程中，经常要用到常数定义，如果是有资源的程序更是如此，自己当初编程时是先将要转换的C语言常数ID复制到程序的常数区。const中，然后再用查找替换功能去掉#define语句，再一个个地在常数和数值之间加equ。

At last , some investgation is made to change about elementary constant of the universe in today ,which demonstrates that elementary constant of the universe in today would change at a ratio of 2.3387723548904887*1050 per year which means that elementary constant of the universe in today would remain as an constant unchanged within one million years if its accuracy fix on the 4th digit after radix point of 7.7577806787995708*1060 As a reminder , both elementary constant of the unvierse elementary constant of the unvierse in today have nothing to do with the cosmic constant introduced by Mr.
