在农田水分平衡中，较难测定的要素有农田蒸腾蒸发量、地下水毛细上升量和土壤水渗漏量。
Of all components of water balance in farmlands, evapotranspiration, capillary rise from a water table and deep percolation are difficult to determine.
然后进行储水系统土样的试验，包括土样的渗透系数测定试验和毛细水上升试验。
Then it carries on soil sample the experiment of the storing water system, including penetration coefficient determination experiment and capillary water rising experiment of the soil sample.
而砂土的毛细水上升高度不受冻融作用的影响。
However, rising height of capillary water in the sand is seldom affected by freezing - melting circulation.
性质：将干燥毛细管的一端与水面接触，则在毛细管中上升，其吸水力即称为毛细管力。
The water content of attraction and capillary decreased with the increase of the matrix suction, which consisted of attraction and capillary powers.
水分上升的动力主要来自于植物的蒸腾拉力和导管的毛细作用。
The impetus of water uptake is "transpiration pull"and capillarity phenomena.
