摘要: 通过实验研究流速对密度锁内温度场和分层的影响，并建立了分区模型。研究结果表明：密度锁可分为混合区、分层区和恒温区，其中分层区又可分为强分层与弱分层，分层界面则位于混合区与分层区之间。此外，本文还将密度锁内温度场分为5类，其中第2类温度场最好，是密度锁正常工作时的最佳选择。

Abstract: The effect of velocity on temperature field and stratification in density lock was studied through experiment. A new zone model was proposed. The results show that fluid in density lock can be divided into three zones including mixing zone, stratification zone and constant temperature zone. The stratification zone can be divided into strong stratification and weak stratification, and the interface is located between the mixing zone and the stratification zone. Additional, the temperature field of density lock is divided into five categories in which the second class is the best for normal work.
