zero-crossing trigger pulse 过零触发脉冲
Result Pulse signal of 20 healthy women and 20 pregnant women were examined by statistic analysis of the time-domain characteristic point zero-crossing position.
结果通过对20例健康人和20例孕妇脉象时域特征点过零点位置的统计及其变化快慢的计算，分析结果正好与实际相吻合。
The zero-crossing of the wavelet transform of the normal person pulse-wave is found out as a fact that its the wavelet transform coefficients correspond strictly to its time field characteristic.
分析了正常的人脉搏信号的小波域特征，发现脉搏信号的时域特点严格对应于其小波变换的过零点。
The reason is that soonest at the next current zero-crossing the firing pulse of thyristors can be reset.
通常的短路故障电流会大大高于这个倍数，而软启动器的晶闸管本身是没有短路分断能力的。
