at regular intervals

Buses to the city leave at regular intervals.

开往城里的公共汽车每隔定时间出班。

He visits me at regular intervals.

他总是间隔定时间访问。

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

在正常的休息时间，震耳聋的摇滚音乐如火山喷，纷纷涌去观看穿着金属外衣的舞者如何展现自己的舞技。
