部件效率 meaning in English

component efficiency

The calculated result shows that there are significant influences of heat transfer on the engine ' s transient performance , and the component efficiency loss caused by tip clearance changes can not be ignored
通过计算分析，零部件与气流之间的热交换对发动机过渡过程性能有显著影响；过渡过程叶尖间隙的变化引起的部件效率损失是不容忽视的。
A mathematical model is developed for simulating transient performance of the turbofan engine , in which the transient heat transfer between the components and airflow , tip clearance and components efficiency changes caused by heat transfer are analyzed
摘要以某涡扇发动机的过渡态性能模拟为研究对象，建立了过渡过程中零部件与气流之间的不稳定热交换、由于热交换引起的间隙变化以及引起的部件效率变化的数学模型，并且将此模型引入面向对象的航空涡扇发动机过渡过程性能模拟程序的框架中。
