渗流

In winter, snow accumulates and melts fast in spring. Snowmelt flood and a summer flood display a double peak pattern of discharge route. In order to simulate the precipitation-runoff features in semi-arid regions, an Atmosphere-Vegetation Interaction model with detailed energy and water transfer processes between atmosphere, vegetation and soil was used.

由于这些特点，在地表水量平衡的计算和模拟中，蒸发的估算十分重要，为此在植被-大气相互作用模式中对水文过程作了改进，模式中包含了大气-植被-土壤间的能量和水分传输过程，特别是半干旱区地表蒸发和植被的蒸腾过程作了比较细致的处理，考虑了蓄满和超渗两种产流机制，同时采用了一个简化的雪盖模型。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
