当脉冲式鉴相器中的时间常数不能忽略并具有附加简单RC网络时，得到了系统稳定的条件。
The stability condition for the system is obtained when the time constant in the pulse operated phase discriminator can not be neglected and with an additional simple RC network.
基于拉格朗日常数变易法，给出这类系统全局指数稳定的一个充分条件。
Based on the Lagrange formula with constants variables, some new sufficient conditions for ensuring globally exponential stability of such systems are derived.
本文进一步研究了这些系数随时间变化而趋于一个定值或在某一常数附近作周期性振荡，并给出容易检验存在唯一全局渐近稳定的正周期解的条件。
In this article we further study the cases in which the coefficients of the model vary with time and tend to definite values or vibrate periodically near certain constants and...
