摘　　要：Josephson结用作参量放大器时出现的反常高的噪声起因于混沌运动.本文综合相平面法与数值方法对Josephson结中的混沌现象进行了研究,并据此初步探讨了Josephson结系统的稳定性.The abnormal noise rising in Josephson junction parametric amplifiers is due to chaos. Chaos occurring in Josephson junctions is investigated by phase-space and numerical methods. In addition, the stability of Josephson junction systems is explored.

关 键 词：相平面法 数值方法 混沌 吸引子 稳定性
