For the forcedcirculation system, to avoid the excessive values of circulation water dynamic, every water cooling tube must be mounted throttle plate in the design.
对于强制循环系统，为了避免循环水动力的多值性，设计均要求在每一根水冷壁管设置节流孔板。
2
The loss of efficient head of circulation pump in the primary loop of PWR will increase with the increase of resistance coefficient of JetPump under forcedcirculation.
强迫循环条件下，压水堆一回路主循环泵有效压头的损失随喷射泵阻力系数的增加而增加；
3
The pressure drop characteristic in natural circulation was compared with that in forcedcirculation.
