增湿作用

加荷增湿作用下Q3粘黄土的结构损伤特性

Structural damage properties of Q_3 loess under tri-axial loading and moistening

分析了草坪的能量平衡机理以及与环境之间的热湿交换关系，说明了草坪对空气具有降温增湿作用。

The energy balance of lawn in urban area and heat mass exchange between lawn and air were analysed .

基于初始切线模量定义的损伤比，能够反映球应力增大和进水增湿作用引起的结构破损变化。

Because the initial tangent modulus decreases gradually with the increase of compression stress and water content and reflects the structural damage increase of loess , this parameter can be used to define the damage variables by the composite theory .

随着光强的减弱，光合有效辐射强度、近地表气温和地温均呈下降趋势，同时空气相对湿度会增加，说明遮阴具有降温增湿的作用同时能减少光合有效辐射。

With the decrease of light intensity , there was a decreasing trend in photosynthesis active radiation , near-surface air temperature and ground temperature . And air relative humidity increased at the same time .

HAT循环关键部件增湿饱和器内是典型的气液两相流动，而液相水滴在饱和器内的平均粒径、平均速度和平均温度分布对饱和器内的传热和传质增湿起很重要作用。

There is typical air-liquid two-phase flow in the saturator of HAT cycle . The distributions of mean diameters , mean velocities and mean temperature of liquid phase droplets are highly important for the heat transfer and mass transfer in the saturator .
