本文首先通过不同淋水高度、淋水密度、过塔风速等的逆流及横流试验塔的热水试验，求出相应条件下的淋水水滴当量直径，再在工业塔的条件下，利用水滴散热公式，计算出雨区散热效果，化为无因次数-冷却数，作出图及计算公式。

To control the ground-water table on irrigated lands is vitally important in arid and semi-arid regions. In order to determine the standard of water table control, considerable attentions were paid to the "critical depth"(or "safe depth") of ground-water table. The salts accumulate in the top soil if the water table is not deeper than this depth. The conditions that the salts accumulate in any layer of the soil owing to the movement of soil moisture are:(1) the supplement of soil moisture from neighboring...
