双能γ射线穿透法测量煤灰分研究

A Study on Determining the Ash Content of the Coal by Dual Energy Gamma-ray Transmission Techniques

本文推导了双能γ射线穿透法测量煤灰分的公式,为数据处理提供了数学依据。在较宽的灰分范围内,实验测量误差好于±1％。

This paper discusses the dependence of gamma-ray interactions with matter on atomic number. A formula of measuring the ash content of the coal by dual energy gamma-ray transmission techniques has been derived to provide the mathematical basis for data processing. The measurement error is less than±1% in the rather wide ash range. Problems encounterred probably in practical application are discussed.
