    摘要:

    本文从孔径分布连续性的角度,讨论了毛管水联系破裂湿度和土壤水运动阶段的划分在定量上的不确定性。同时,根据土壤-植物-大气连续体系水分热力学函数的实测资料,论证了在判断土壤水运移方向时,摘增加原理的局限性和偏摩尔Gibbs自由能减小原理的适用性。并且进一步阐明了水流第二定律的三个基本点,以及在应用该定律时曾经出现的误解。

    Abstract:

    From the continuation of pore distribution, the uncertainty in quantity for the wettness of the capillary moisture bound disruption and the classification of soil water moving stages is discussed. According to the measured data of the moisture thermodynamic functions in the soil-plant-atmosphere continuum, we identified the limitation of the principle of entropy increasing and the suitability of the principle of partial molar gibbs free energy decreasing when judging the direction of soil water movement. Moreover, a further interpretation is made on three basic points of the second law of water flow and the misunderstanding when using the law.
