The chapter 9 establishes one two - overlapping generations model , analysis the macro - economic effect of the system transform . the chapter 10 uses one simple vertical equilibrium model , discusses the probability and process of gaining the equilibrium by extend the coverage without reform the current scheme . as the last chapter of the whole paper , chapter 11 summarizes the paper conclusions 其中：第九章建立了简单的两期叠代模型，分析了养老保险制度转轨的宏观经济影响，考察了制度转轨的时机与条件；第十章建立了简单的横向均衡模型，探讨了在制度内实现均衡的现实性、可能性，并对引进新的参保对象实现制度的横向均衡进行了数值模拟。
The original nonlinear system is linearized to one one - order system and one two - order system . then design methods for linear systems can be adopted to design each system separately . thirdly , a new fuzzy control method is introduced to design the aircraft microwave landing system , which is based on analytically optimal correction function without quantization 本文以国产某型飞机为对象，应用基于微分几何的非线性多输入多输出系统输入一输出反馈线性化方法，对飞机原始非线性微分方程进行输入输出反馈线性化，将其等效为解耦了的一个一阶线性系统和一个二阶线性系统。
