排量曲线 meaning in Chinese

curve of displacement
delivery curve of pump
discharge curve

This thesis analyze the effects of its mechanism dimension to the working properties with many of date , and the flux curve of principal and subordinate piston mortar pump , and the effects of the transition working area of the compensatory cylinder to the working properties , and find the differences between the actual properties and the theoretical model , proposes the measures for the improvements , as well as gives the guiding instructions for the mortar pump design
数据分析了主从活塞式砂浆泵机构尺寸参数变化对泵工作性能的影响，分析了主从活塞式砂浆泵的排量曲线，以及补偿缸工作的过渡区间对泵工作性能的影响，找到了泵实际工作性能与理论模型的差别并提出改善措施，对该砂浆泵的设计提出指导性建议。
