常見例句雙語例句In the second design step, improvement of wing's aerodynamic characteristic is mainly depended on the weakening of shock which reduces wave drag during the wing section optimization.在平面形狀優(yōu)化基礎(chǔ)上，在機(jī)翼容積不變約束下，再采用剖面翼型優(yōu)化設(shè)計，通過機(jī)翼剖面細(xì)微變化弱化較大馬赫數(shù)下的激波、減小激波阻力。hkxb.buaa.edu.cn 返回 aerodynamic wave drag
