| 摘 要： | 用Ｆｏｋｋｅｒ－Ｐｌａｎｃｋ算子法建立了处理分段连续调制下的双井随机共振问题的理论方法，并对方波和锯齿调制情况进行了解算。文中用线性响应理论对结果加以处理，并发现了随机共振现象。分析方法包括了绝热近似下的结果，并适用于非绝热的情况。

| Abstract: | A model for double-well system driven by white noise and modulated by periodic segmented function is constructed. The result for square-wave modulation case is obtained as well as toothingwave case. The linear-response theory play an essential role in the analysis, and stochastic resonance is found. This analysis covers the adiabatic results, and also can be applied to nonadiabatic cases as well. |
