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.

Now, it is trying its best to pass the certification of OHSAS18001 Occupational Health and Safety Management System.

企业通过了ISO 9001质量管理体系、ISO 14001环境管理体系和OHSAS 18001职业健康安全管理体系认证。

The addition of iso-octane extends the knocking limit in equivalence ratio somewhat, however the knock occurrence mainly depends on the total concentration of mixture. Although the operation range in equivalence ratio becomes narrow with the increasing of iso-octane, the maximum load is improved 80% by n-heptane/iso-octane controlled real-time in contrast with the HCCI fueled with n-heptane only.

结果表明：混合燃料HCCI着火以及燃烧相位主要取决于正庚烷实际的燃空当量比；异辛烷的加入对爆震当量比界限有所拓展，但HCCI爆震主要与混合燃料总当量比有关；随着辛烷值比例的提高，导致HCCI运行范围变窄，但是实时调控证明相对纯正庚烷，混合燃料的HCCI燃烧最大负荷提高了80%。
