提出一种理论计算结合实验测量来确定穆斯堡尔（Ｍｏｓｓｂａｕｅｒ）谱实验样品最佳厚度（ｄｏｐｔ）的办法。在穆斯堡尔谱测量中，信噪比（Ｑ）可用一个解析式来表示，其值随实验样品厚度的变化有一个极大值，它对应于样品的最佳厚度ｄｏｐｔ．研究表明，要确定一个样品的最佳厚度ｄｏｐｔ，除了清楚其化学成分外，若准确知道样品的无反冲分数ｆａ，则可以直接通过理论计算来求ｄｏｐｔ；否则，就要用本文介绍的办法来确定ｄｏｐｔ。
A theoretical calculation combined with experimental measurements was proposed to determine the optimal thickness (dopt) for Mossbauer spectra. In the Mössbauer spectroscopy, the signal-to-noise ratio (Q) can be expressed as an analytic value with a maximum value corresponding to the optimum thickness dopt of the sample as a function of the thickness of the experimental sample. Studies have shown that, to determine the optimal thickness of a sample dopt, in addition to clear its chemical composition, if accurately know the sample without recoil fraction fa, you can directly calculate the theoretical dopt; otherwise, we should use the method described in this article To determine dopt.
