摘要

在穆斯堡尔谱仪中，驱动速度的质量指标主要在于它的稳定性和非线性。稳定性将在谱线宽度中反映出来，它主要取决于零电平漂移、参考信号幅度的微小不稳定以及驱动电路中放大单元的不对称漂移。而后二者通常在整个速度扫描中可以好于10

。速度的非线性是一个更重要的指标，它取决于速度参考信号的线性、反馈回路的增益以及拾波线圈响应的线性度（图1）。如果采用多道分析器，道址——道位置间的非线性关系也是一个重要的影响因素。而速度的非线性直接影响谱峰的位置，从而影响所得穆斯堡尔参数的精度。

Abstract

Velocity non-linearity is an important specification for Mössbauer spectrometer. The different way of determining the nonlinearity was discussed and some suggestions were presented.
