Inflammatory cell infiltration and bronchiolitis severity were significantly reduced ofter administration of E. globulus oil. Especially in 300 mg·kg -1 treated rats,there were significant decreases of mucin content in BALF and MUC5ac expression in trachea and bronchiole epithelium. Optical density and mucins area% detected by image analysis system were apparently lower than those in model group. Conclusion: E.

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.

The results indicated that irrigation water supply and dripper discharge had extreme effects on the moisture uniformity in soil along the drip irrigation pipe direction for line source drip irrigation, the soil moisture uniformity would be raised with the increase of irrigation quantity and dripper discharge.

试验表明：线源滴灌下，灌水量、滴头流量、滴头间距对沿滴灌管方向的土壤湿润区均匀性影响最大，随着滴头流量或灌水量的增加以及滴头间距的减小，湿润均匀性提高。

By mono-factor analysis of the point drip infiltration,the horizontal and vertical movement distance of soil wetting front were not only in close relation with dripper discharge and drop water,but also had good power functional relation which exists with the soil characteristic ( soil density, soil initial moisture).
