A draining structure with original creation which is selected by the test is presented, its drainage effect is better than that of similar structures at home and abroad. 试验选出疏水结构的疏水效果远远超过国内外同类结构,具有独创性。
A hydraulic mathematical model of furrow. irrigation with free draining end boundary was established by using the kinematic-wave method in this paper, and a good agreement between the model result and the field test was found. 本文利用运动波方法建立了自由排水沟尾边界的沟灌水力学数值计算模型,并与田间灌水试验结果进行了比较,一致性良好。

The discharge pressure for the fan pre-start test was 1 234.6 kPa at the end of the draining period, 772.3 kPa lower than that for the fan normal-start test. 结果表明:当排水阶段结束时,风机提前启动除霜实验的排气压力为1234.6kPa,比风机正常启动除霜实验的排气压力低772.3kPa;
