【Abstract】 The source of nonlinear system is given based on some typical situations of changing-rate,saturation, oscillation, multiple-value responses circulation,glitch,collapsing and so on.And the different characteristics from linear systems are discussed such as initial-value related statibility,possibly generated self-oscillate and entering chaos states from balanced ones after leaving the stable states.The research on the features of nonlinear system will be helpful for discovering causality of objects’ production and development.And the great contribution to determine the fixed states of non- periodicsignals is analysed for the development of systematic science.更多还原
