From now on, I will give a discuss about cosmological perturbation theory, and I will use English instead of Chinese, since most of the ideas are easier to be expressed in English.

Though there are many literatures on this subject, I still want to make an effort, try to tell the story with my own words, this is an challenge for me.

The plan is as follows: 1)in the first few articles I will discuss the main ideas of this theory, such as how to define perturbations and how will they transform under a generic coordinate transformation;(2)after introducing these concepts, I will talk about how to study the evolution of these perturbations both in Newtonian and General Relativity frames;(3) finally I will give some simple applications of the perturbation theory.
