摘要
在分析Gunn效应的耦合模方程组的基础上，进行截断近似．采用六耦合模方程组对微波场中Gunn振荡进行了数值计算，得到倍周期锁模特性．在微波场强度变化的一定范围内，倍周期模式锁定不变．其结果比较好．
Based on the analysis of the coupled-mode equations for the Gunn effect, a cut-off approximation is discussed. With six coupled-mode equations, the mode-locking characteristica under an externally applied microwave field are analysed. The Grnn oscillation entrains the period- doubling mode as the amplitude of microwave field is changed in a definite range.
