中文摘要：

月球表面的微波辐射亮度温度与月表地质结构和月表物质的物理化学特性相关。为了对月球亮温分布异常区域进行地质分析,文章首先计算嫦娥亮温数据的时角,采用克里金插值的方法得到了不同频率不同时刻中低纬度的微波亮温图。结合奇异值分解（SVD）模型分析了月表亮温变化异常,结果表明风暴洋位置和靠近月海东北部的高地区域等存在亮温变化异常,月海区域（除风暴洋外）为3 GHz和37 GHz两个场的总体相关区域。通过对月球火山分布地区的区域亮温变化进行分析,发现这热异常可能是由于月球火山活动造成的。

英文摘要：

China＇s Chang＇E-2 is for the first time equipped with a passive microwave radiometer（MRM） to measure the brightness temperature of different lunar surfaces. To make geological analysis of the anomaly of brightness temperature,the authors calculated the hour angle of the brightness temperature data and obtained the brightness temperature of middle and low latitudes at different frequencies and in different periods by Kriging interpolation method. The anomaly of brightness temperature on lunar surface was obtained based on the SVD model. The result shows that Oceanus Procellarum and the highland region of northeast lunar mare with concentrated volcanic rocks constitute the brightness temperature anomaly area. The large lunar mare area is an overall correlation region of 3 GHz and 37 GHz.
