衬质势，基质势
基质势
Examples
- Standard guide for measuring matric potential in vadose zone using tensiometers
拉力计测定渗流区矩阵势能的标准指南 - Infiltration mostly depended on matric potential gradient and the effect of upslope runoff could be omitted , when initial water content was very low
当初始含水量较低时，入渗主要受控于基质势梯度的作用，上方来水对入渗几乎没有影响。 - The results in this study can be summarized by the following : ( 1 ) some difference of calculated soil hydraulic conductivity and soil matric potential are existed in different soil hydraulic models
研究结果表明：不同的土壤水力模式对土壤水力传导率和土壤水势的计算结果是有差异的，而这种差异会影响陆面模式中土壤湿度的模拟。 - In low matric potential state , the a & p model can be use to predict water retention characteristics , but in high matric potential state , it cannot get good result . in addition of soil pore connectivity , to correct the a & p model , it can get good result in whole water content range
但在高吸力段a & p模型预测的结果与实际偏差较大，考虑到土壤孔隙实际联通状况，修正a & p模型，使供试的四种在整个含水量范围对土壤水分特征曲线都得到了较好的拟合。 - ( 3 ) when evaporation was stopped during the process of soil water redistribution , soil water would move downslope by gravity . when evaporation was in process , due to low initial water content , most infiltrated water from small intensity and amount of rainfall would be consumed by intensive evapotranspiration during rainy season , and lateral downslope unsaturated flow seldom took place . however , soil water would move downslope by gravitational and matric potential gradients after continuous rainfall
( 3 )在防止蒸发条件下，再分布过程中，土壤水分在重力的作用下有沿坡向下运移的趋势；在蒸发条件下，由于初始含水量一般较低，雨季量小且分散的降雨极易为强烈的蒸发蒸腾所消耗，侧向沿坡向下流难以发生，但在持续的降雨条件下，土壤水分在重力势和基质势梯度的作用下易沿坡向下运移。
