- In this dissertation , the experimental study of rolling condition on two - phase flow instabilities of the forced - single - tube circulation system was carried out . furthermore , based on the d - partition method and the hypothesis of drift flow model , given some conservative equation , using the perturbation method the response of the pressure drop of the tube to the inlet flow rate perturbation was analyzed both in rolling condition and in normal upright position
本文主要通过实验对摇摆条件对单管强迫循环中汽液两相流动不稳定性的影响，同时在d分区法的前提下，在两相区基于漂移流模型，一定的守恒条件下，在摇摆和不摇摆工况中用线性小扰动法对实验段的压降对入口流速的扰动的响应进行了分析。 - The research work on the chaos is carried out in chapter 5 . the properties of chaos sensitively dependent on the initial conditions and the perturbations are proved and a method of controlling chaos of duffing oscillator is investigated as well . in chapter 6 , the bifurcation and chaos of continuous nonlinear systems are researched
第五章用正规摄动法给出了一维非线性微分方程的通解，并以此为基础解析地证明了混沌运动对初值的敏感依赖性和对扰动的敏感依赖性，并以杜芬振子为例子以验证，研究了杜芬振子的混沌运动控制的多谐扰动法。
