摘要:根据月壤(FeO+TiO2)含量数据和“嫦娥2号”卫星CELMS数据,对月球东海地区微波辐射特性进行了研究。结果表明,在东海内部(FeO+TiO2)含量较高的地区,其正午和午夜时刻的亮温值都比较高,亮温差值也比较大,但亮温及亮温差值的分布随频率变化呈现不均匀性;Maunder撞击坑的(FeO+TiO2)含量较低,但其低频和高频亮温及亮温差值的表现正好相反;区域F(约10°S/106°W)、G(约5°S/104°W)和以(13°S/103°W)为中心的区域的微波辐射存在明显异常。这些区域的微波辐射特性对研究东海地区的形成演化过程具有重要意义。

Abstract:As Mare Orientale is the youngest and best preserved multiring impact basin on the Moon, it is of essential importance to study its composition and structure for clues to the processes and histories of older, more degraded features. In this paper, the (FeO+TiO2) abundance derived from Clementine UV-VIS data and the CELMS data from Chang’e-2 satellite are employed to study the Microwave Emission features of the Mare Orientale. The results indicate that the regions with high CELMS data and high brightness temperature difference agree well with high (FeO+TiO2) abundance both on noon and on midnight. However, the change of the area with high CELMS data and high brightness temperature difference with the frequency indicates that the composition of the lunar regolith is varied with depth. The (FeO+TiO2) abundance in Maunder Crater is low, whereas the CELMS data and the brightness temperature differences in the low frequencies and the high frequencies show distinctly different features, which indicates that the composition of the lunar regolith here in the upper layer and the lower layer may be different. The abnormal microwave emission apparently exists in the regions (10°S /106°W), (5°S /104°W) and (13°S /103°W) in highland with low (FeO+TiO2) abundance, which is likely related to the temperature gradient of the deep regolith.. The microwave emission features in these areas are of special significance to study the evolution of the Mare Orientale.
