常見例句雙語例句Both panel method and lifting surface method can be used to calculate the unsteady force.非定常力可以采用面元法或升力面方法計算得到。A numerical method is presented for prediction of propeller performance and pressure distribution on blade surface according to lifting surface theory.本文提供了一種根據(jù)升力面理論計算螺旋槳槳葉表面壓力分布和螺旋槳性能的數(shù)值方法。Lifting surface method and non-linear vortex lattice method were used for the calculation of propeller and rudder with additional thrust fins respectively.對螺旋槳與舵附推力鰭分別采用升力面法和非線性渦格法計算。權(quán)威例句Airships demonstrate a law of increasing returns: doubling the length increases the surface area (and hence weight) by a factor of four while the volume (and hence lifting capacity) goes up by a factor of eight.ECONOMIST: Pushing the envelope 返回 lifting surface
