常見(jiàn)例句雙語(yǔ)例句To predict helicopter vortex ring state boundary is necessary for flight safety.直升機(jī)渦環(huán)狀態(tài)邊界的確定對(duì)直升機(jī)飛行安全具有重要意義。A reasonable criterion of vortex ring state boundary for helicopter is acquired based on model rotor tests.通過(guò)模型旋翼試驗(yàn)得到了合理的直升機(jī)渦環(huán)邊界判據(jù)，并由此計(jì)算得到了直升機(jī)通用渦環(huán)狀態(tài)邊界。The result shows that the model of neural network can predict the effect of blade negative-twist on helicopter vortex-ring state.計(jì)算結(jié)果表明，神經(jīng)網(wǎng)絡(luò)模型能夠準(zhǔn)確預(yù)測(cè)槳葉負(fù)扭度對(duì)直升機(jī)渦環(huán)狀態(tài)的影響。 返回 vortex ring state
