Dividing the actual flow by the theoretical value calculated above will yield a value which, taken as a percent, indicates volumetricefficiency.
实际流量除以理论流量得出一个数值，以百分比计，表示的即是容积效率。
2
Valve timing is a major factor in achieving good volumetricefficiency.
定时阀是实现高容积效率的一个主要因素。
3
The hydraulic fluid viscosity, the volumetricefficiency and the hydraulic system working efficiency drops, divulging increases, even causes the mechanical device to be unable the normal work.
