摘　　要：深地、深海和深空探测是国家重大科技战略,也是世界前沿研究领域.火星探测是深空探测的重要组成部分,而对行星内部结构的探测又类似于地球上的深部探测,因此,火星内部探测可认为是深空与深地探测的结合,总结和梳理目前火星深部研究进展,发现新的研究增长点有着重要的意义.本文综述了主要基于“洞察”号观测数据的火星地震学研究进展,包括火星震特性和火星内部结构探测的新认识,重点介绍利用“洞察”号搭载的单地震台站研究火星介质波速度随时间变化的原理及目前观测到的波速日变和季节性变化等方面进展,并类比地球和月球上相关研究分析了火星波速变化的影响因素,最后总结了目前火星地震学及介质时变的研究进展,并展望了利用单地震台监测火星介质时变的发展趋势和研究机遇.The exploration of the deep earth,deep sea,and deep space represents a major national science and technology strategy,and is also a cutting-edge research field in the world.Mars exploration falls within the realm of space exploration,whereas probing the interior of an exoplanet resembles the deep earth exploration.Consequently,exploring the subsurface structure of Mars can be considered a combination of deep space and deep earth exploration.It is of great significance to summarize and sort out the current research progress of Mars and find new research content.This article reviews the research progress of Mars seismology based on InSight data,including the new understanding of marsquakes properties and the investigation of Mars internal structure.The focus is on the background,principle and new progress of the studying on temporal velocity changes in Martian subsurface structure using the single seismic station onboard InSight and the observed diurnal and seasonal variation of seismic velocity are introduced.The influencing factors of Mars seismic velocity change are analyzed through relevant studies on the Earth and Moon.Problems and opportunities in the study of temporal changes in Martian media are also summarized.Finally,we prospect the research direction and development trend of time-varying monitoring of Martian media by using single-station method.
