The basic structure of ultrasonic vibrators is studied in this paper.

本文给出了一种大功率超声振动子的基本结构。

Vibrators, Boiling Out units, Polymerization Units and some other machines.

真空混合机，震荡机，煮盒机，聚合设备和其他技工机器。

All the conventional vibrators use the sweep signal of which the instantaneous frequency shows linear change with time.

常规可控震源都是采用瞬时频率随时间线性变化的扫描信号。
