摘　　要：在简要介绍了动态锁区形成原理后 ,通过对 RL G基本输入输出关系的推导得出了动态锁区的宽度表达式。基于减小动态锁区影响的目的 ,建立了相应的优化模型。优化结果表明 :适当增大抖动深度对减小动态锁区的影响是必要的 ,但当抖动深度增大到一定程度后 ,再增大抖动深度对减小动态锁区没有明显的效果 ,而根据优化结果进行局部调整却可能得到很好的偏频效果。In the article, the width of dynamic lock in is obtained by deducing the basic input output equation of RLG Corresponding optimal module is based on the purpose of reducing the influence of dynamic lock in The result of the optimization shows that it is necessary to enlarge dithering depth to reduce the nonlinear influence When dithering depth is much large, there is no evident effect on the reduction of dynamic lock in by enlarging it further However, it is expected that much perfect unlocking should be obtained by modulating dithering depth according to the result of optimization
