   研究异重流具有非常重要的现实意义。
2. The sediment density current is very complicated . the contributions by this thesis supply a good basis for further study on the density current . so it has a practical value
   本论文中所推导出的双层计算模式下的异重流方程可作为今后建立异重流数学模型的基础，具有一定的应用价值。
3. After a comprehensive review on the study of sediment density current in the recent several decades , a set of differential equations for 2 - d density current under double - layer computational mode is established . by simplifying th . set of equations , a 2 - d numerical simulation of sediment density current and sediment outflow has been made in the liujiaxia reservoir in the yellow river basin , and the result is reasonable
   本论文在对异重流运动近几十年来的研究成果进行较系统、全面论述的基础上，针对目前研究较为前沿的异重流运动数值模拟问题，提出了一套二维异重流双层计算模式下的基本方程，并在这套方程简化的基础上，对黄河流域刘家峡水库中的异重流运动和排沙进行了二维数值模拟，结果令人较为满意。
4. On the one hand , the sediment density current often does a great harm to the reservoir , and causes a big loss of reservoir ' s storage capacity or makes reservoir severe deposition ; on the other hand , sediment outflow by density current is an effective measure to mitigate sedimentation
   异重流(本论文中主要指因含沙量的差异而形成的浑水异重流)一方面常常给水库带来严重的危害，加速水库的淤积和库容的损失；但另一方面它又为水库排沙提供了一种极为有效的途径? ?水库异重流排沙。
