摘　　要：介绍了利用激光诱导击穿光谱(LIBS)对煤粉进行元素分析的有关技术.利用脉冲激光器激发煤粉样品产生荧光;利用光谱仪、BoxCar、数据采集卡获得荧光光谱数据;利用LabView编程实现煤粉中元素成分分析.文章以煤中碳含量测量为例介绍了元素分析的关键技术.给出测量精度标准偏差(SD)值不超过1.6%,可以满足燃煤电厂对煤质的分析要求.这种技术同样可用于煤中其它元素的分析测量.An appealing technique for elemental analysis of coal is described in the article by use of laser induced breakdown spectroscopy （LIBS）. The technique employs a pulsed laser focusing on coal samples to generate plasma fluorescence. A portion of the plasma light is collected and recorded by using spectrometer, BoxCar, data acquisition card and the component analysis of elements in coal is obtained by LabView program. The key technologies of the elemental analysis are introduced with the carbon content in coal as an example, and the measuring standard deviation （SD） does not exceed 1.6 %, which can meet the analysis requirements of the coal fired power plants. This technique also can be used for the analysis of other elements in coal.
