By means of fundamentals of hydraulics, multi-equations of hydraulic computation are set up for irrigation systems with parallel pumps and low-pressure water transferring pipes.
运用水力学的基本原理，建立了多泵并联低压管灌系统水力计算的方程组。
The ways to reduce the maximum pressure were also proposed in this paper. It provided the reference to determine the parameter in transferring cryogenic liquid and to design the pipes.
并提出了减少压力最大值的方法，对于低温液体输送参数的确定、管道的设计提供参考。
Hoses and pipes used in the transferring process should always be kept clean and capped.
软管和管材在移交过程要一直坚持洁净和上限。
