rate of surface runoff的意思|示意

The soil evaporation, leaf transpiration rate and surface Infiltration of PS was highest, surface runoff was lowest, relating to porosity of PS.

在土壤蒸发、叶片蒸腾、地下入渗中PS最高，在地表径流中ps最低，这与PS的孔隙度有关。

Along the experiment time was prolonged, the corrosion products was appeared on the surface of sample. Then the runoff effect became more aggravated, so the dynamic corrosion rate was elevated.

随着试验周期的延长，表面产生了腐蚀产物，这时冲刷作用对试样表面腐蚀产物膜的破坏更加严重，所以冲刷腐蚀速率比浸泡腐蚀速率增加。
