中子活化瞬发γ多元素能谱分析的工业应用

Industrial Application of Neutron Activation prompt γ Analysis

介绍了用中子活化瞬发γ分析方法测定煤中元素含量的原理、仪器及测量结果。灰分的测量精度 ( 1σ)为± 0 .3 %～± 0 .7% ,含硫量的测量精度 ( 1σ)为± 0 .1%～± 0 .3 %。

The principle, instrument and measurement result on the element contents in coal by use of the neutron activation prompt γ analysis method is briefly reported. The measure precision (1σ) of the ash content is ±(0.3～0.7)% and the measure precision (1σ) of the sulphur content is ±(0.1～0.3)%.
