In case of the turbine is operated departing the optimum condition, the low presure and the vortex band will be established in the draft tube centre by the flow circulation.
水轮机在偏离最优工况运行时，水流的环量会使尾水管中心产生低压并形成涡带。
In this band wave of the vortex, there are formed called "LANDS" group of young people in this band.
在这个乐队风潮的旋涡中，有组建了名为“LANDS”这一乐队的一群年轻人。
Tower has two giant holes, the sea at an alarming speed from the two giant holes flow, which rolled up strong spray, a huge vortex, so that this band wave surging waters, the sea fog with activity.
塔上有两个巨洞，海水以惊人的高速从这两个巨洞中流过，从而卷起狂澜，形成巨大旋涡，使这一带水域的浪潮汹涌澎湃，海面雾气腾腾。
The calculated results indicate that the across-wind loads of high-rise buildings with square sections are induced mainly by vortex shedding and are narrow-band random processes.
得到如下结论：高层建筑横截面为方形时，其横风向风荷载主要由规则性旋涡脱落导致的尾流激励构成，为窄带随机激励；
