The reference location is typically either the fixed excitation location when performing a shaker excitation or the stationary accelerometer location when performing an impact test.
典型情况是，要么当进行激振器激励时激励位置固定，要么进行锤击试验时加速度位置固定。

In this paper an impact-digital method for calibrating the charge sensitivity of piezoelectric accelerometer is presented. It is a quick and practical method.
用微计算机校准压电式加速度计的电荷灵敏度系数是一种快速实用的方法。
