介绍了用ＧＺ－４Ｂ型测振仪对旋转机械进行现场平衡的方法。利用此法可迅速确定不平衡量的大小、方位，不仅可以进行单校正面平衡，也可以进行双校正面平衡。
The method of on-site balancing of rotating machinery with GZ-4B vibrometer is introduced. Using this method can quickly determine the size of the imbalance, bearing, not only for single-school balance, but also for double-school balance.
