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(jié)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驗的基礎(chǔ)上，討論了結(jié)皮土壤的濺蝕規(guī)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.
實驗表明：凈風(fēng)對土表的風(fēng)蝕作用微弱，即使在遭到大風(fēng)吹刮時，土表的結(jié)殼仍不易受到破壞。
