Quantitative Analysis on Volatile Component of Fired Coal Based on Laser-induced Breakdown Spectroscopy
摘要
Abstract
21 coal samples with known volatile components were used for laser-induced breakdown spectroscopy (LIBS)ex-periment.According to structure characteristics of coal quality,wave band strength of characteristic spectral lines of coher-ent elements was selected as input for regression analysis and multiple regression calibration method and partial least squares (PLS)was respectively introduced to realize quantitative analysis on volatile component in fired coal.By comparing calibra-tion results of the two methods,conclusion was drawn as that indexes including model coefficients,average relative error of predictive samples,root-mean-square error of predictive samples and so on from PLS algorithm were superior to those from multiple regression calibration method which might be more suitable for quantitative analysis on volatile component based on LIBS and obtain higher analysis precision.关键词
