at regular intervals

Buses to the city leave at regular intervals.

开往城里公共汽一定时间发出一班。

He visits me at regular intervals.

他总是间一定时间访问我一次。

At regular intervals, deafening rock music erupts and the crowd rushes to ogle skimpily clad dancers strutting their stuff.

在正常休息时间，震耳聋摇滚音乐如火山喷发，人群纷纷涌去观看穿着金属外衣舞者如何展现舞技。
