Timing information is then transmitted to an entity of the asynchronous cellular communication system to determine time-of-day at the entity.

接着，将定时信息发射到所述异步蜂窝式通信系统的实体，以确定所述实体处的日时。

PWM timing is the most advanced one among all 3-phase asynchronous motor timing methods. This article introduces the essential components of PWM control loop, and the key parts of the loop.

PWM调速是当前三相异步电动机调速中最有前途的一种方法。本文在介绍了PWM调速方法的基础上，对其中的关键环节进行了较深入的研究。
