(=vivid) 活潑的, 鮮明的, 光亮的

In order to avoid VIV, the reduced velocity is used as a co. 為防止管道發(fā)生橫向渦激振動,用約化速度作為控制條件,確定管道允許懸空長度。

Viv : [Looks in tank] Ooh, here come the feeders. Sorry, I wanna watch this! 薇薇：（看著水族箱）喔，喂食的人來了。不好意思，我想看這個！

It shows that the modal shape and mode frequency are highly coupled with the VIV response of a marine riser with low mass ratio. 該模型的計算結果表明，立管的模態(tài)振型、模態(tài)頻率與渦激振動響應高度耦合，并且對于低質(zhì)量比的情況尤為明顯。

Compared with conventional steel riser (SR), AAR has better VIV fatigue characteristics. 與常規(guī)鋼制隔水管(SR)相比，鋁合金隔水管具有較好的VIV疲勞特性。

Viv : Maybe, but most of those people are sane. The guy at the zoo had definitely lost his marbles. 薇薇：也許，不過那些人大部分都很正常。動物園那家伙鐵定是瘋了吧。

VIV fatigue damages of AAR depend on flow profile shapes, and vary significantly with position. 結果表明，AAR的渦致疲勞損傷依賴于流動剖面的形狀，且在不同位置處差別較大。
