But there are also some disadvantages in it, for example, single sprinkler hard hose traveler waste much energy, hydraulic losses are large, so optimize design of it become especially important.
The hydraulic performance of the sprinkler is a key factor to the quality of the sprinkler system, and the test and the remark are the base of designing and spraying.
喷头水力性能是喷灌系统质量好坏的关键因素，它的测试评价是进行喷灌工程设计、施工以及进行喷灌的基础。

The hydraulic performance test is needed for the further optimization of structural size of fluidic sprinkler.
