摘要
结合GB/T 476对三节炉法测定煤中碳氢含量的操作方法进行分析,详细探讨了空白的来源与操作注意事项、吸收管和燃烧管的维护及使用的规范方法,用试验数据说明了规范操作的意义,从原理及影响方面阐述了规范操作的目的。
According to GB/T 476,the operation of Liebig method in the carbon-hydrogen determination of the coal was analyzed in this paper.Moreover,the origin of the blank,handling precautions,maintenance and standard operation method of the adsorption tube and combustion tube were discussed in detail.And the significance of standard operation was illustrated with the experimental data.
