【摘要】 利用中子活化分析方法对云、贵、川三省部分原煤中的常量、微量及有害元素的含量进行了检测 ,获知燃煤中主要的固态有害元素的大致分布情况 ,对防治由燃煤引起的大气污染起到了积极的作用。同时介绍了原煤燃烧前后大部分固态元素的变化规律更多还原

【Abstract】 The elemental contents in coal produced from southwest china were determined by NAA. the distribution of the harmful elements in coal was obtained. The results are helpful to control the air pollution caused by coal buning. the transformation behaviours of the major elements from the mine coal to burnt ash were also presented.更多还原
