【摘要】：Tycho撞击坑作为月球最具代表性的哥白尼纪撞击坑,其微波热辐射特性的研究对于分析与其同期形成的大型撞击坑的热演化过程具有重要的参考价值.本文基于嫦娥二号微波辐射计(CELMS)数据为代表的月壤微波热辐射数据,结合月壤TiO_2含量、表面坡度和粗糙度、岩块丰度等资料,系统分析了Tycho地区微波热辐射的特征.结果表明,Tycho撞击坑南坡(A区)的微波热辐射受月表温度影响很大,月壤表层和深部的温度差值也很大;坑底平原北部(B区)的微波热辐射受月表温度影响很小,月壤表层和深部的温度差值也很小;该东部和西部的月壤结构在垂直方向上是有变化的;在凌晨3时以后该区达到热平衡状态,是未来进一步研究月壤内部热流特性的理想区域;溅射毯地区月壤物质在表层与B区相近,且具有较强的储热能力.统计结果表明,表面粗糙度和岩块丰度对月壤微波热辐射的影响最大,坡度次之,TiO_2含量的影响最小.
[Abstract]:As the most representative Copernican impact crater on the moon, the study of microwave thermal radiation characteristics of Tycho impact crater has important reference value for analyzing the thermal evolution process of large impact crater formed at the same time. Based on the microwave thermal radiation data of lunar soil represented by the (CELMS) data of Chang 'e-2 microwave radiometer, the characteristics of microwave thermal radiation in Tycho area are analyzed systematically based on the data of TiO_2 content, surface slope and roughness of lunar soil, and the abundance of rock mass. The results show that the microwave thermal radiation in the south slope of the Tycho impact crater (area A) is greatly affected by the monthly surface temperature, and the temperature difference between the surface layer and the deep part of the lunar soil is also very large, and the microwave thermal radiation in the northern part of the bottom plain (area B) has little effect on the monthly surface temperature. The temperature difference between the surface layer and the deep part of the lunar soil is also very small; the structure of the lunar soil in the east and west of the region is changed in the vertical direction, and the thermal balance is reached after 3 am in this area. It is an ideal region to further study the internal heat flux of lunar soil in the future. The surface layer of lunar soil in sputtering blanket area is close to that in B area and has strong heat storage ability. The results show that the influence of surface roughness and abundance of rock on microwave thermal radiation of lunar soil is the biggest, and the effect of tio _ 2 content on the slope is the least.
