air-entry value

基本解釋

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(zhì)的重塑樣，初始乾密度越大，則其進(jìn)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(xiàng)式的擬郃獲得的土-水特征曲線，得出進(jìn)氣值和殘餘飽和度對(duì)應(yīng)的基質(zhì)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(dǎo)出用分維和進(jìn)氣值表示的水分特征曲線和滲透系數(shù)的理論表達(dá)式。

進(jìn)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(dǎo)率與基模吸力的關(guān)系判斷和測(cè)定了土壤的進(jìn)氣值,採用改進(jìn)後的砂型漏鬭裝置測(cè)定了土壤的發(fā)泡點(diǎn)。
