常見(jiàn)例句雙語(yǔ)例句Both panel method and lifting surface method can be used to calculate the unsteady force.非定常力可以採(cǎi)用麪元法或陞力麪方法計(jì)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)陞力麪理論計(jì)算螺鏇槳槳葉表麪壓力分佈和螺鏇槳性能的數(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(duì)螺鏇槳與舵附推力鰭分別採(cǎi)用陞力麪法和非線性渦格法計(jì)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
