This paper studies the main geometrical parameter such as angle, height, width, stagger and the upper width in dentation and trapezoid flow path, firstly, uses the single-phase numerical simulation of the computational fluid dynamics technique to analyse the influence of different geometrical parameter on discharge coefficient and flow state exponent of drip emitter. Secondly, uses the two-phases numerical simulation of CFD (1% sand content ) to analyse the influence of the above mentioned geometrical parameter on the contribution regulation of sand and anti-clogging performance. Thirdly, uses the PIV （ particle Tracking Velocimetry ） technique which can see the small-scale flow path to observe and test the trajectories and velocities of solid particles in labyrinth flow path, and analyses the basic factors which can influence the movement characteristic of solid particles and the flow state in flow path.

All weighing tests should be made in the standard atmosphere for testing textile.after the specimens have been conditioned in the same atmosphere.it may be impractical to condition the specimens in option A or nonconditioned testing may be agreed upon by the purchaser and supplier.when the full rolls or bolts of fabric can not be properly conditioned in a resonable time with available facilities,perform the tests without conditioning and report the actual conditions prevailing at the time of the test.such results may not correspond with the results obtained after testing adequately conditioned specimens in the standard atmosphere for testing textiles.

D1776实际操作的定向试块。纺织品的所有的权衡测试都应该在标准大气压下进行。当试块被置入同等气压的条件之后，或许将试块限制于A选项是不切实际的，而且有可能条件测试并不一定会被供应商和客户认同，当充满凹凸不平和毛刺的织物不能被适当的限制与合理的时间和现有的设施的时候，在没有限制的情况先执行试验并准确的报告在测试时的有力条件。这样得到的对纺织品测试的结果或许会与在真空中得到充分限制测试的结果不相一致。
