利用 CE1-GRS 数据分析月表钾元素分布特征
Global Distribution Analysis of Potassium on Lunar Surface Using CE1-GRS Data
摘要
Abstract
In order to acquire the global distribution of potassium (K ) on the lunar surface ,the methods and data processing procedure of the Chang ’E-1 (CE1) gamma-ray spectrometer (GRS) were studied using the level 2C spectra data measured by the CE1-GRS , and the preliminary global count map of K was derived . K is primarily concentrated within and around the western-most maria on the nearside and a secondary abundance concentration is located in the South Pole-Aitken basin .On the farside ,K generally shows the feature of low abundance .Compared with the global map of K measured by the Lunar Prospector (LP) GRS ,the result shows that major features of the global K distribution appeared in CE1-GRS map are consistent with that from LP-GRS .关键词
