1·Groundwater systems have shallow phreatic water-confined water system and medium layer confined water system.
地下水系统具有双层含水结构：浅层潜水——承压水系统和中层承压水系统。
2·Stormflow consists of phreatic water, surface runoff and weather horizon-passing rain. The rise and drop of their discharge are consistent with that of the river discharge after rain.
潜水河雨后地表径流由地表下潜水、雨水地面上径流、雨水风化层径流构成，三部分水均随河道流量的增减而增减。
3·Through the description of geological and hydrogeological conditions in the Baiyang water resource field, mathematical models of phreatic groundwater flow and groundwater quality are established.
对白杨水源地的地质和水文地质条件进行简要论述，在此基础上建立了二维潜水地下水水流和水质的数学模型。
4·The variation characteristics of shallow confined groundwater are similar with phreatic water.
浅层承压水含水组的地下水质变化特征和潜水基本一致。
5·The research supplies a new method for quantitative study of steady phreatic evaporation of sand-layer soil.
该实验为定量研究夹砂层状土壤潜水蒸发提供了新思路。
