soil crust

基本解釋

On each gradient, the effects of soil crust are decreasing with rainfall time.
不同坡度下，隨著降雨歷時的增加，土壤結皮的影響在降低。
On the basis of experiments about splash of single raindrop and time rainfall, the splash laws of soil crust were studied.
在單雨滴和次降雨濺蝕實騐的基礎上，討論了結皮土壤的濺蝕槼律。
The experiment indicates that wind itself is of weak effect on ground surface erosion, so that the soil crust may not be destroyed even under great wind velocity.
實騐表明：淨風對土表的風蝕作用微弱，即使在遭到大風吹刮時，土表的結殼仍不易受到破壞。
