摘要

介绍了测量煤炭灰分的低能γ射线反散射方法。研究了最佳灵敏度的条件和最佳几何配置、成分变化对测量的影响和补偿方法。测量范围为8%—15%

标准误差为±0.37%。

Abstract

Backscattering techniques for determining the ash content of coal are introduced. Optimum sensitivity and optimum geometric configuration are studied. The effect of constituent’s variation on measuring results is calculated and some compensation methods can be established to correct the effect of variation of Fe2O3 contents on practical measurement. Measuring range is 8%—15%

and the r.m.s. of measuring deviation is less than ± 0.37%.
