(=vivid) 活泼的, 鲜明的, 光亮的
In order to avoid VIV, the reduced velocity is used as a co. 为防止管道发生横向涡激振动,用约化速度作为控制条件,确定管道允许悬空长度。
Viv : [Looks in tank] Ooh, here come the feeders. Sorry, I wanna watch this! 薇薇：（看着水族箱）喔，喂食的人来了。不好意思，我想看这个！
It shows that the modal shape and mode frequency are highly coupled with the VIV response of a marine riser with low mass ratio. 该模型的计算结果表明，立管的模态振型、模态频率与涡激振动响应高度耦合，并且对于低质量比的情况尤为明显。
Compared with conventional steel riser (SR), AAR has better VIV fatigue characteristics. 与常规钢制隔水管(SR)相比，铝合金隔水管具有较好的VIV疲劳特性。
Viv : Maybe, but most of those people are sane. The guy at the zoo had definitely lost his marbles. 薇薇：也许，不过那些人大部分都很正常。动物园那家伙铁定是疯了吧。
VIV fatigue damages of AAR depend on flow profile shapes, and vary significantly with position. 结果表明，AAR的涡致疲劳损伤依赖于流动剖面的形状，且在不同位置处差别较大。
