1·In the Yellow River lacustrine plain, the phreatic water is mainly recharged by the irrigated water diverted from the Yellow River.
黄河冲积平原中，黄河灌溉水入渗补给是该地区潜水的重要来源。
2·And using the experimental formula and mathematical model, the computing formula for the phreatic water evaporation is educed.
并且利用潜水蒸发的经验公式和数学模型，推导出潜水蒸发的计算公式。
3·The results showed that, the laws of evaporation of phreatic water with crop growing was remarkably different fron that without crop growing;
结果表明，种有作物情况下的潜水蒸发规律与裸地显著不同；
