The unsteady flow in a jetpump is calculated and the reasonable calculation result was gotten based on above research.
在此基础上对射流泵内非定常流动进行了数值模拟，得到了合理的计算结果。

The effect of Jet-Pump in the transient procedure of natural circulation and the resistance behaviour of Jet-Pump in the different flow condition have been analyzed.
分析了喷射泵在压水堆一回路自然循环过渡过程中的作用以及在不同流动条件下的阻力特性。
