摘　　要：对月球的探测是人类在太空探索的第一步。介电常数是用来描述物质材料在外加电场中储存和释放能量能力的参数,对月壤介电常数的测量有助于人类研究月壤厚度和次表层结构,了解月球的起源和演化历史。人类主要通过对月壤样品进行检测、微波遥感探测以及雷达就位探测等三种方式测量月球表面和内部的介电常数。文章主要介绍了各国对月壤介电常数的反演方法、结果及介电常数的主要应用。同时,文章还结合测量结果,简要比较了各种测量方法的优劣,总结出各方法的差异,并基于之前的研究,展望了中国对检测嫦娥五号采集的月壤介电常数和反演火星介电常数的进程。Exploring the moon is the first step of human exploration in space.The dielectric constant is used to describe the ability of a material to store and release energy in an applied electric field,and the measurement of the dielectric constant of lunar regolith is helpful for human beings to explore the thickness and subsurface structure of lunar soil and understand the origin and evolution history of the moon.The dielectric constant of the moon’s surface and interior is mainly measured through three methods:direct detection of lunar soil samples,microwave remote sensing detection,and radar in-situ detection.This article mainly introduces some methods of calculating the lunar dielectric constants,their results and basic applications of dielectric constants.Additionally,it also mentions both advantages and disadvantages of these methods and compares the precision of their results.Finally,based on previous researches,this paper prospects for detecting the dielectric constant of the lunar regolith samples collected by Chang’e 5,and it also looks forward to the progress of studying the dielectric constant of Mars.
