摘　　要：本文基于国际深空探测任务的经验教训,结合我们近期的研究成果,提出了适用于深空探测行星表面原地定年的新方法——激光无稀释剂K-Ar反等时线法,以及实现该方法的LIBS-QMS技术方案。该方案充分发挥了K-Ar法在深空探测特殊条件下的优势,有望成为深空探测、行星演化研究的关键方法,为太阳系演化研究提供关键时间信息。同时,该研究为我国即将展开的月球、火星、水星及小行星落地探测研究等深空探测科学任务提供了可行、可靠的相关载荷技术方案,并为我国月球科学基地提供在站科研仪器。Based on the experiences and lessons learned from international deep space exploration missions,combined with our recent research results,we have proposed a new method of“laser unspiked K-Ar inverse isochron technique”for in situ dating of the planetary surface of deep space exploration and made a practice design of the LIBS-QMS combination technology scheme for this method in this paper.This technique will give full play to the advantages of the simple and practice remote K-Ar dating method in special conditions of deep space exploration.It is expected to be a key method for the deep space exploration and planetary evolution research,and for providing critical time information of the solar system evolution research.addition,this research will provide feasible and reliable relevant payload technologies for China’s upcoming deep space exploration missions to the moon,Mars,Mercury and asteroids,and will be helpful for providing on-site scientific instruments for China’s lunar science base.
