water sorption meaning in English

吸水作用

And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity , showing cn bear the efficient capacity of control soil loss . nevertheless , when soil is saturated , the runoff intensity of both tillage systems is near , implicating cn has the limited function of reducing runoff . 2 ) based on the case analysis of observed all rainfall - runoff generation processes , a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils , which is attributed to the property of rapid water sorption and much non - capillary porosity
经近几年的观测和理论分析，取得了以下结果和创新的认识： 1 )在降雨强度较大的情况下，保护性耕作制? ?聚土免耕的产沙强度明显较常规耕作制? ?顺坡耕作的小，说明聚土免耕耕作制防治土壤流失是有效的；但当土壤达到饱和后，聚土免耕的径流强度与常规耕作的差异较小，产沙强度也增大，因此，聚土免耕防治水土流失的能力是有限的。
