摘要
Abstract
According to the actual needs of Chinese coal testing,a series of 15 types of reference samples of trace elements in coal were prepared.This paper introduced a high homogeneity quantitative fractional pack method in reference sample preparation process of trace elements in coal,meanwhile,the homogeneity and stability of sample were studied particularly,which would ensure good homogeneity and stability for this series of reference samples,and make them meet the national standard sample requirements.关键词
