临界激励 meaning in English

critical excitation

For the reduced system , the mean square criterion of stochastic melnikov process is derived to give the critical values of the probable onset of chaos and the conclusion is that the critical value turns from increase to decrease as the amplitude of weiner process increases in the interested parameter range
然后重点讨论了平均系统，经过推导得出相应的随机melnikov过程，用均方值准则导出随机系统可能产生混沌运动的临界条件，由此得到了在一定的参数范围内，随着weiner过程强度参数值的增大，混沌的临界激励幅值先递减继而递增。
