at regular intervals

Buses to the city leave at regular intervals.

开往城里的公共汽车每隔一定出一班。

He visits me at regular intervals.

他总是隔一定访问我一次。

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

在正常的休息，震耳聋的摇滚音乐火山喷，人群纷纷涌去观看穿着金属外衣的舞展现自己的舞技。
