| 摘 要： | 介绍了激光感生击穿光谱技术(LIBS)的原理及应用现状，并且给出了利用激光感生击穿光谱技术测量飞灰含碳量的方法与分析结果。选用煤种是焦作无烟煤，通过快速灰化法得到含碳量在0．5％～7．0％之间的飞灰样品。利用LIBS技术测量飞灰的含碳量，并且与传统的重量燃烧法测量得到的飞灰样品的含碳量进行比较。结果表明两种测量方法的结果吻合得很好。

| Abstract: | The theory of laser-induced breakdown spectroscopy (LIBS) and its present status of application potential are described and the measurement of carbon content in fly ash by using this method and results of analysis presented. The rank of coal selected is Jiaozuo anthracite. By a method of rapid incineration fly ash samples with carbon content ranging from 0.5% to 7.0% were obtained. The measurement of carbon content in fly ash by using LIBS technique was compared with the carbon content in fly ash samples measured through the use of traditional weight combustion method. The results of the two measurement methods are in very good agreement. |
