摘　　要：阐述了激光诱导等离子体光谱技术的物理机制,分析了气压影响激光诱导等离子体光谱探测的机制和规律,建立了低气压环境下进行激光诱导等离子体光谱探测的试验装置,开展了不同等级低气压环境下的试验研究,通过试验数据具体量化了气压对激光诱导等离子体光谱探测的影响,进而论证了激光诱导等离子体光谱技术应用于月球探测的可行性.The physical principle of laser induced breakdown spectroscopy （LIBS） was interpreted. How the pressure affects the laser induced plasma was analyzed. A LIBS experimental system for the low pressure condition was setup and the experiments at the different pressures were carried out. The experimental result expresses how the pressure affects the laser induced plasma quantitatively. The feasibility on the application of LIBS to lunar exploration was discussed.
