| 中文摘要: |
| 本文对考虑不流动水影响下的溶质运移模型、可动-不动区溶质运移模型、考虑吸附与降解作用的不流动水溶质运移模型进行了综述。指出对不流动水的研究已从盲端水扩展到内聚体间不动的水和远离流动区的水。其中，用可动-不动区模型可解释溶质运移中穿透曲线不对称的现象；用压力圆盘渗透仪可直接测量不动区的含水量使上述模型易于操作。并指出今后不流动水研究的方向应为不流动水分类的完善、不流动水对包气带水流的影响研究、参数的不确定性和尺度效应研究。 |

| Some solute transport model considering the effect of immobile water,adsorption and degradation are reviewed in this paper.It is pointed that the study on immobile water has been extended from dead-end water to nonmoving intra-aggregate water and isolated water.The asymmetry of breakthrough curve can be well described by mobile-immobile mode.The disk pereameter is used to measure the immobile water content directly and it makes mobile-immobile model more operational.The further studies of immobile water will be focused on the complete classify of immobile water,The effect of immobile water on water flow ,the uncertainty of the parameters and the scale effect. |
