Since it is impossible to know the consequences of allthese variables each time paint is applied, a simple field method is needed toarrive at the proper pressure.
鉴于每次喷涂时不可能知道是哪些变量所造成的结果，所以需要一个简单的现场试验来判断压力是否合适。

I do sports or listening to music, I think this method is very good to ease the pressure, and the time is short.
我会运动或者听歌，我觉得这样缓解压力的方法很好，而且时间很短。

Basing on the laws, the paper applies the pressure-flow distinguishing method into the pipeline leak detection, and through using the method of detecting the time of pressure fall.
