调频同步广播系统是具有重叠服务区，使用同一载频和同一节目源，同时同相位广播的调频发射技术。

FM sound sync-broadcasting has overlapped service zone, the same carrier frequency and the source of the program, which can broadcast in-phase at the same time.

不同的发动机，其配气相位和气门重叠是不一样的。

This is called valve overlap. Valve timing and valve overlap vary on different engines.
