Because the short time interval which is asynchronous between the time interval measured and the clock pluses filled exists in the any time measurement.

因为对任意的时间测量都存在着被测时间间隔与填充脉冲之间所不同步的短时间间隔。

Based on pulse counting principle, the high precision time interval can be obtained by measuring the number of the high-frequency reference clock through it.

设计了一种高精度时间间隔测量模块，该模块由单片机控制，采用脉冲计数原理，通过测量时间间隔内高频参考时钟个数，得到被测时间间隔的精确值。

I wouldn't set an alarm, but if you find yourself looking at the clock, give yourself structured work time and structured play time in an interval format to get you through the day.

那就打破你的计划吧。 我不会设一个闹钟，但如果你发现自己会时不时看时间，给自己一个规划好的工作时间和玩乐时间，让自己熬过这一天吧。
