The relationship between evaporation from groundwater and soil moisture suction beneath root zone is very well. 有作物条件下潜水蒸发与作物根系层下的土壤水吸力关系较好,提出了利用土壤水吸力计算有作物条件下潜水蒸发的方法。
The amount of evaporation in Yangtze basin and Three Gorges zone will increase only by several thousandths; 兴建三峡水库后,流域及三峡区间的蒸发量只增加了千分之几;
With the evaporation of dispersed droplets, there creates temperature difference between dispersed phase and the continuous, so distribution of volume heat transfer coefficient along the axial within the evaporation zone is developed. 分散相液滴不断吸热气化,导致气升管轴向上连续相和分散相的温度变化,从而产生不同的传热推动力,形成体积传热系数分布。
From mountains to silt plain along with the formation, runoff and disappear of inland rivers, the distributing regularity of F~-can be markedly divided into three hydrochemical zones: drench and dissolution-runoff zone, runoff-evaporation zone, dissolution-evaporation zone. 随干旱区内陆水系的产生、径流消亡,从山区至山前细土平原,F~-的迁移分布具有显著的淋溶-径流、径流-蒸发与溶滤-蒸发浓缩富集3个水文化学分带;
There are four currently competing models of mechanisms that lead to an SSD-ADAF transition, i.e., strong ADAF principle, evaporation, Honma mechanism and thermal instability in the inner SSD zone. 关于SSD-ADAF的转变机制目前有强ADAF原则、蒸发机制、Honma机制和SSD内区的热不稳定引发机制。
The steam-water system includes two mathematical models: the evaporation zone and the single-phase heat exchanger. 汽水系统的数学模型包括蒸发区和单相介质换热器的数学模型。
