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 .

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 high-energy physics experiments need to determine a signal generation time this work is mainly done by the timing discriminator .

高能物理实验中需要确定一个信号的产生 时间，这个工作主要由定时 甄别 器来完成。

At the same time Recuring to the programed phase discriminator and frequency divider the value of work frequency was scaled with digit accurately .

同时，借助于可编程 鉴 相 器和分频器电路将信号频率点数字化、精确化。

Digital frequency detector can be very precise and achieve a most high resolution however at the cost of more time . Analog frequency discriminator has much faster response but lower resolution and stability .

目前，采用数字方法研制的鉴频能达到较高的分辨力和稳定性，但频响 往往较低，而用模拟方法 制作 的 鉴 频 器虽频响较高，但稳定性和分辨力指标下降了。

Like C + + only one member of the union is active at a time and that member can be determined from the discriminator .

像C++一样，一 次只能有一个联合成员是活动的，并且可以从其 识别 名称来确定该成员。
