渗入深度 depth of penetration
Subsoiling can increase soil water content and enhance water infiltration depth to 80 cm compared with the control whose depth is only 40 cm.
与对照相比,深松可以增加土壤含水量并可以提高水分入渗深度,深松区土壤水分入渗深度可达80 cm左右,未深松区土壤水分入渗深度只有40 cm左右。

通过室内和野外模拟降雨的入渗和蒸发实验，研究不同降雨量条件下，沙地的最大入渗深度、入渗速率以及每天的蒸发量。
By indoor and field simulated experiments of infiltration and evaporation of the rainwater, the paper studies the depth and velocity of infiltration and the daily evaporation.
已有的研究表明，土壤中重力水的入渗深度能够指示土壤干层的有无和发育强弱，是决定植被类型的最主要和最关键的因素。
The research shows that the influx depth of gravity water in soil can indicate the existence of dried soil layer and the degree it developed, which is the key factor to decide the kind of vegetation.
入渗深度与降雨量和降雨强度之间存在线性关系，土壤渗透能力随土壤剖面初始含水量的增加而减小，土壤稳定入渗速率的时间趋于缩短。
The infiltration rate is intensively affected by rainfall intensity, and there exists a linear relation between the depth of infiltration and precipitation and rainfall intensity.
