摘　　要：介电常数是衡量月球介电特性的重要参数。利用月球介电参数可以反演月壤厚度、密度等重要物性参数,有助于研究月球地质构造和地质演化历史。获取月表介电参数的方法主要为雷达远程遥测、月表雷达就位探测和月球样品测量,其中月球样品测量是最为直接有效的测量方式。阿波罗任务总共获得了约381 kg月球样品,总结了阿波罗月球样品介电参数测量方法,分析了测试结果。测试结果表明,频率、温度、湿度、密度和氧化物等因素会影响样品介电参数测量。在后续样品介电测试中,需要考虑这些因素。Dielectric constant is an important parameter for measuring the dielectric properties of the Moon.The dielectric parameter of the Moon can be used to invert important physical parameters such as the thickness and density of lunar regolith,which is helpful for studying the geological structure and evolution history of the Moon.The main methods for obtaining the dielectric parameter of lunar surface include radar remote sensing,in-situ detection,and lunar sample measurement,among which lunar sample measurement is the most direct and effective one.Apollo missions have obtained a total of about 381 kg of lunar samples.The measurement methods for dielectric parameters of Apollo lunar samples are summarizes,and the test results are analyzed.The test results indicate that factors such as frequency,temperature,humidity,density,and oxides can affect the measurement of dielectric parameters,which should be considered in subsequent sample dielectric tests.
