matric potential 中文意思是什麼
matric potential
解釋
襯質勢，基質勢-
Standard guide for measuring matric potential in vadose zone using tensiometers
拉力計測定滲流區矩陣勢能的標準指南 -
Infiltration mostly depended on matric potential gradient and the effect of upslope runoff could be omitted, when initial water content was very low
當初始含水量較低時，入滲主要受控于基質勢梯度的作用，上方來水對入滲幾乎沒有影響。 -
( 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 ）在防止蒸發條件下，再分佈過程中，土壤水分在重力的作用下有沿坡向下運移的趨勢；在蒸發條件下，由於初始含水量一般較低，雨季量小且分散的降雨極易為強烈的蒸發蒸騰所消耗，側向沿坡向下流難以發生，但在持續的降雨條件下，土壤水分在重力勢和基質勢梯度的作用下易沿坡向下運移。 -
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
研究結果表明：不同的土壤水力模式對土壤水力傳導率和土壤水勢的計算結果是有差異的，而這種差異會影響陸面模式中土壤濕度的模擬。 -
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模型預測的結果與實際偏差較大，考慮到土壤孔隙實際聯通狀況，修正a & p模型，使供試的四種在整個含水量范圍對土壤水分特徵曲線都得到了較好的擬合。
