摘　　要：本文研究非线性时变系统随时间变化出现的平衡轨道分岔和运动轨迹突变现象,提出了与之相关的基本概念.本文指出,社会经济系统的运动具有非线时变系统的分岔和突变特性,可以运用计算机仿真的手段分析其平衡轨道分岔点和运动轨迹突变点,并根据仿真结果进行政策调整.This paper concerns with the equilibrium orbits'bifurcation and trajectory catastrophe of time-dependent systems,it presents some new concepts and discusses the characteristics of 1-dimension system. It indicates that a social and economic system has the same characteristics as a general timedepen-dent system, its bifurcate-point can found by means of computer simulation, we can revise our policies so as to get the best result.
