摘要
一个动力系统的状态依赖于其中的控制参数。许多描述保守或耗散系统的非线性方程,在一定的参数范围内表现出内在的随机性。本文就一类强迫非简谐振子出现随机行为问题作一些讨论并给出数值计算的结果。
The state of a dynamical system is dependent on its controllable parameters. Many nonlinear equations, describing either conservative or dissipative systems, show stochastic behaviour in suitable range of parameter values. In this paper, some discussions and calculations about stochastic behaviour of a kind of forced anharmonic oscillator will be given.
