The dependence is obtained experimentally of the output properties of sppc and mppc coexistence on pump parameters of both the pump beams 通过实验得出了sppc和mppc共存时的相位共轭输出特性对二束泵浦光的泵浦参数的依赖关系。
Note : on pump discharge , the preferred check valves are an in - line spring loaded , swing design with lever and weight or lever and spring 注意:在泵的排泄口处,首选的止回阀是管内弹簧负载,旋启式,配置杠杆和重量或杠杆和弹簧。

Centrifugal pump is a commonly hydraulic machine , whose inner flow has direct influence on pump ' s performance and is a considered problem by the pump designers 离心泵是一种通用水力机械,其内部流动情况一直是泵设计人员十分关注的问题,因为泵内流动的优劣直接影响泵的性能。
In europe , taxes account for up to four ? fifths of the retail price , so even quite big changes in the price of crude have a more muted effect on pump prices than in the past 在欧洲,税金占汽油零售价的五分之四,因此,即使原油价格发生很大的波动,汽油价格所受的影响也不会像过去那么显著。
