Based on the brief review of generation process of the two core-system hypothesis, the essay mainly analyses the core point, working mechanism and experimental basis of the two core-system hypothesis, including the experimental basis on the small precise representative system and large approximate representative system.
在简要回顾双系统假设产生过程的基础上,重点分析了双系统理论的要点、工作机理、实验依据,具体包括小数量精确表征系统和大数量近似表征系统的实验依据。

近似系统
1.
the approximate system to show that there exist just two single limit cycles,or just one double-limit cycle,or just one single-limit cycle and one separatric cycle are given.
利用Mel’nikov函数,对一类具有以抛物线与直线为边界的周期环域的单中心二次Hamilton系统的三次扰动,分别构造出恰好存在两个单重极限环、恰好存在一个二重极限环、恰好存在一个极限环和一个分界线环的近似系统。

Starting from the definition of the stability of y=φ(t) in the terms of the systemdy[]dt=φ(t,y),the definition of the stability for odds solution X=0 is given in the view of the systemdx[]dt=f(t,x); and based on the definition,the result is got that the odds solution of simple approximate system dx[]dt=Ax is stable rather than approximately stable in the system of dx[]dt=f(x).
从系统dydt=φ(t,y)关于y=φ(t)在李雅普洛夫意义下的稳定性出发,给出了系统dxdt=f(t,x)关于其零解x=0的稳定性定义,并在该定义的基础上,得出了自治系统dxdt=f(x)的一次近似系统dxdt=Ax的零解为稳定而非渐近稳定的结论。
