1)  capillary water
毛管水
1.
The writer fully and clearly introduces that capillary water is transmiting pressure,the direction of capillary water motion is restricted by upper layer temperature change of soil and soil surface evaporation and the same motion direction of stream state water in the soil(from hot to cold).
土壤中毛管水是传递压力的,毛管水运动的方向,受土壤上层温度变化和土面蒸发制约,与土壤中汽态水的运动方向(由热至冷)一致。
2)  upward capillary water
上升毛管水
1.
The paper analyzed the relationship between height of upward capillary water and time and the relationship between height of upward capillary water and underwater replenishment.
针对西北地区因过量灌溉而引起的土壤盐渍化问题,通过室内模拟土柱试验,对地下水埋深较浅(仅为地面以下70 cm)的均质土上升毛管水运动特性进行了研究,分析了毛管水上升高度、地下水毛管补给量与时间之间的关系,以及毛管水上升高度与地下水补给量之间的关系,探明了地下水毛管上升的运动机理。
3)  capillary water of soil
土壤毛管水
4)  characteristic of capillary water upward movement
毛管水上升运动特性
5)  the maximum height of the capillary water rise
毛管水最大上升高度
1.
According to the fact that the viewpoints on whether the interlayer soil influences the maximum height of the capillary water rise or not always keep difference,the maximum height of the capillary water rise in sand-layered soil was studied through the experiment and analysis which was based on the dynamics theory of the soil water movement.
针对目前层状土体剖面夹层土质对毛管水分最大上升高度的影响存在较大分歧,以沙土夹层为例,从土壤水动力学的角度,通过实验和理论分析,分不同情况对层状土壤的毛管水最大上升高度进行了系统研究。
6)  capillary water rise and distribution

CAS号:

性质:土壤毛管孔隙中靠毛管力(弯月面力)作用保持和移动的液态水。按水的来源毛管水可分为悬着毛管水和支持毛管水(上升毛管水)两个基本类型。靠降水和灌溉水下渗到土壤中而存在于毛管孔隙内的水分称为悬着毛管水,与地下水层联系。靠地下水沿毛管上升到土壤中所保持的水分称为支持毛管水,与地下水紧密相接。毛管水是土壤中移动较快而又易被植物吸收和利用的水分,养分在土壤中的迁移和转化,与毛管水密切相关。
