中文摘要：

从理论上分析了电光双稳态系统的稳定性，通过图解方式研究了各不动点的稳定性．用数值求解的方法，确定了分岔点的具体位置，分析了该系统是经过倍周期分岔和阵发混沌途径产生混沌．数值模拟由系统状态随参量变化的分岔图和最大李雅普诺夫指数随参量的变化关系，表明本文的理论分析结果是完全自洽的．

英文摘要：

The stability of the electrical-optical bistable system is theoretically analyzed and the stability of the fixed points is researched by diagrammatized mode. Through the method of numerical caculation, the concrete positions of the bifurcation points are caculated,the ways of chaos generation are studied which are intermittent chaos and period doubling bifurcations. Bifurcation diagram of the system state evolving with parameter and largest Lyapunov exponent changing with parameter of the system all show that the analysis is reasonable in theory .
