摘　　要：阐述了激光诱导离解光谱技术的工作原理,论述了激光诱导离解光谱技术的元素识别过程,分析了元素识别误差存在的原因,有针对性地提出了基于标准样品原子谱线的元素识别方法,建立了一套激光诱导离解光谱探测试验系统,对标准样品和待测样品进行了相关试验,试验结果证明了基于标准样品的元素识别方法的可行性和识别优势.The working principle of the laser induced breakdown spectroscopy （LIBS） was interpreted. The elemental recognition process was discussed. The reason for elemental recognition error was analyzed. A recognition method based on the standard samples was suggested. A LIBS experimental system was setup and the experiments for the standard and unknown samples were carried out. The feasibility and the recognition advantages of the method were proved by the experimental results.
