Laplace变换中复变量S的量纲及其物理意义

The dimension of complex variable s and it's meanning of reality

本文提出经Ｌａｐｌａｃｅ 变换后复变量Ｓ具有一定的量纲，对其分析研究，可以顺利获取控制系统一些重要指标。认为许多数学变换一定包含着深刻的物理意义。

In this paper,the writer puts forward the complex variable s that is translated by the Laplace transfermation that has a certain dimen sion.Through analysis and research,we can obtain some important parameters of control system,and at the same time,the writer consider many mathematic transfer has abundent physical meannings.
