摘　　要：综述了激光诱导击穿光谱分析技术(LIBS)在不同对象领域应用中的谱图分析方法。随着激光诱导击穿光谱应用对象的不断扩展与分析要求的变化,其定量分析方法已不局限于传统标样定标曲线分析模型,发展出了自由定标模型、各类内标法模型、自相关定量模型、神经网络分析模型等新的激光诱导击穿光谱分析方法。对每种方法的定量分析原理、分析能力水平与适用对象范围进行了详细的分析比较。An overview about the models and approaches of quantitative analysis by laser induced breakdown spectroscopy （LIBS）, as a tool of element analysis and material identification, is presented. With the expansion of application of laser induced breakdown spectroscopy and the analytic aims varying, the relevant quantitative method is also developed. Beside the calibration analysis, all kinds of new models and approaches, such as calibration-free model, internal standard method, correlation analysis, artificial neural network and so on, are reviewed in detail. For each quantitative method, the fundamental, performance parameter and field of application are compared and analyzed.
