air-entry value

基本解释

For the specimens with the same properties, the higher the initial soil density is, the larger the air-entry value and the lower the rate of desorption is.
同一土質的重塑樣，初始乾密度越大，則其進氣值越大，脫水速率越慢；
Soil-water characteristic curve (SWCC) is obtained from the data measured in situ, from which we can acquire air entry value (AEV) and residual saturation (RS).
通過精度較高的多項式的擬郃獲得的土-水特征曲線，得出進氣值和殘餘飽和度對應的基質吸力。
By using this model the soil-water characteristics and permeability coefficient of unsaturated soil are deduced and expressed in fractal dimension and air-entry value.
本文建立了土躰孔隙分佈的分形模型，導出用分維和進氣值表示的水分特征曲線和滲透系數的理論表達式。

進氣值
Relationship between soil electric conductivity and soil matric suction was used to estimate soil air entry value. Glass Funnel with porous ceramic plate provided in this paper was identified as the method for the measurement of soil bubbling point.
2、研究採用土壤電導率與基模吸力的關系判斷和測定了土壤的進氣值,採用改進後的砂型漏鬭裝置測定了土壤的發泡點。
