摘　　要：在地球、太阳和其他行星的引潮力的作用下,月球表面上任一点重力值将产生周期性的变化称为月球重力固体潮理论值.研究月球重力固体潮有助于我们更好地了解月球的内部结构、地壳运动以及月球的演化过程,这也为登月任务和月球探测提供了重要的科学依据,帮助我们更好地探索和理解月球的特性和性质.本文阐明了月球重力固体潮形成原因,根据category5月球内部结构模型计算出月球重力潮汐因子,依据Newcomb理论,采用ELP2000-85解析星历和Eckhardt月球天平动模型,提出一个计算月球重力固体潮理论值的方法,选取Apollo11作为测站,以波形图的形式输出该测站一天、一个月、一年的月球重力固体潮理论值,并探索讨论月球重力固体潮与月震的关系.结果表明:该测站一天、一个月、一年的月球重力固体潮理论值,最大值分别为:-1309μGal、-1290μGal、-1277μGal;最小值分别为:-1343μGal、-2349μGal、-2349μGal;与地球重力固体潮(这里选择与Apollo11经度纬度相同的坐标作为测站相比),月球重力固体潮变化相对简单,但波动幅度较大;推测月球的重力固体潮与深源月震之间可能存在某种关联.Under the influence of tidal forces from earth,the sun,and other planets,periodic changes in the gravity value at any point on the lunar surface are called the theoretical value of lunar gravity solid tides.Studying the lunar gravity solid tide helps us better understand the internal structure,crustal movement,and evolution of the moon.This also provides important scientific basis for lunar missions and exploration,helping us better explore and understand the characteristics and properties of the moon.This article elucidates the reasons for the formation of lunar gravity solid tides,calculates the lunar gravity tidal factor based on the category 5 lunar internal structure model,and proposes a method for calculating the theoretical values of lunar gravity solid tides using the ELP2000-85 analytical ephemeris and Eckhardt lunar libration model based on Newcomb theory.Apollo 11 is selected as the measuring station,and the theoretical values of lunar gravity solid tides for one day,one month,and one year are output in the form of waveform diagrams,And explore and discuss the relationship between lunar gravity solid tides and lunar earthquakes.The results show that the theoretical values of lunar gravity solid tides for one day,one month,and one year at this station are-1309μGal,-1290μGal,and-1277μGal,respectively;The minimum values are-1343μGal,-2349μGal,and-2349μGal,respectively;Compared with the earth's gravity solid tide(where coordinates with the same latitude and longitude as Apollo 11 are chosen as the measuring station),the lunar gravity solid tide changes relatively simple,but the fluctuation amplitude is relatively large;It is speculated that there may be some correlation between the gravity solid tide of the moon and deep source lunar earthquakes.
