　　摘　要：

　　LIBS在深空探测领域的优势近年来逐渐被人们所认可，相应的在此领域的研究也得到了重视和发展，并已经被NASA计划实际应用到2009年的火星探测项目MSL中。LIBS应用于月球表面元素成分探测具有显著的探测优势：对目标的快速定位，快速采样和遥感探测；几分钟的短积分时间；多元素同步探测；表面清洁能力——利用重复脉冲除去目标表面的尘土和风华层；ppm量级的探测限和探测灵敏度；高探测精度和准确度；能够探测几乎所有元素（包括H元素）。这些探测优势综合起来可以使得登陆车在有限的工作时间里返回更多、更有效的探测数据，极大的提高了探测效率。另一方面，月球表面的高度真空状态对LIBS的探测过程影响较大，研究低压条件下LIBS的探测能力和探测特征是将来LIBS可能应用到月球探测的难点和关键所在。本文通过低压环境下真实样品的LIBS试验探测和数据分析，初步研究了LIBS应用于月球探测的可行性和存在的问题，并取得了一定的研究成果。

Abstract: The advantage of LIBS for application to space exploration is recognized gradually in the past few years, corresponding study has been emphasized and developed, and a LIBS instrument has been selected by NASA for the mobile Mars Science Laboratory (MSL) rover, scheduled for launch in 2009. There are remarkable advantages for LIBS’s application to analysis of samples on Moon: fast aiming at the selected target; rapid sample acquisition; stand-off analysis capability; rapid analysis (one measurement/pulse); simultaneous multi-element detection; surface cleaning ability to remove dust or weathered layers with repeated laser pulses; high detection sensitivity (ppm); high detection accuracy and precision; ability to detect all elements (include H). These advantage together can effectively increase the scientific return during the limited operational lifetime of a craft. On the other hand the low pressure on the Moon has a significant influence on the detection process of LIBS, and study on the detection
ability and detection properties in low pressure is a difficulty and a key for future possible application on Moon. In this paper the LIBS detection on different sample is carried on based on a LIBS experiment system. The feasibility and difficulty of LIBS’s application on Moon is studied primarily and some result is obtained.
