其实闸门开启过程中的出闸水流属非恒定流。
In fact, however, in the process of sluice opening, the outflow is unsteady flow.
闸门关闭，水位上升，下一个闸门开启，再次关闭，水位再次上升，往复这个过程。
Gates close, water rises, gates open; then close, up, open again.
计算结果显示，在贯流泵站起动过程中，闸门开启延时时间以及闸门开启速度对起动过渡过程均有明显影响。
The results show that, in the tubular pump start the process, the delay time of opening gate and the speed of the starting gate are significant influence the transition process.
