micro-irrigation emitter的意思|示意

But the flow path in Micro-irrigation emitter is so small that plug happened easily, so filtering system is needed to add to the header of irrigation system.

但其灌水器流道小，易堵塞，需在系统首部增设过滤装置，砂过滤器即是生产中最常用的一种。

The measured hydraulic parameter of this kind of emitter provides an important design parameter for micro-irrigation engineering design.

测出的此种滴头的水力性能参数，为微灌工程设计提供了重要的设计参数。
