blade force meaning in Chinese

叶片力

The main research outcomes were as follows : ( 1 ) the paper applied quasi - three dimensional design model and optimization design model based on si flow surface that was effected by runner ( impeller ) and guide vane jointly . the vortex flow , blade thickness limitation and runner ( impeller ) blade force functions were taken into account . the paper got the improved runners of hl240 type , which were runner hlx240d and runner hlx240e
主要成果有： ( 1 )应用考虑转轮来流有旋、叶片有限厚及转轮(叶轮)叶片力作用的转轮(叶轮)与导叶联合作用的基于s _ 1流面的准三维设计模型和优化设计模型，研究出了hl240的改进型转轮： hlx240d和hlx240e 。
