【摘要】：為了從嫦娥系列繞月γ能譜測(cè)量實(shí)驗(yàn)獲取月表γ能譜特征,應(yīng)用CE1-GRS和CE2-GRSγ能譜2C級(jí)科學(xué)數(shù)據(jù),首先從散射本底扣除后的譜線中提取出弱特征峰信息,然后對(duì)嫦娥系列儀器譜進(jìn)行定性分析,推定月表存在的可能元素種類。結(jié)果表明:(1)從CE1-GRSγ能譜能識(shí)別U、Th、K、Fe、Mg、Si、Al和O等8種月表可能元素,從CE2-GRSγ能譜能識(shí)別U、Th、K、Fe、Mg、Si、Al、O、Ti和Ca等10種月表可能元素;(2)衛(wèi)星繞行軌道距月表距離越近、探測(cè)器的能量分辨率越高,得到的月球軌道γ能譜將更精細(xì),從而能獲取更準(zhǔn)確的月表元素種類及其分布特征。
[Abstract]:In order to obtain the gamma-ray spectrum characteristics of lunar surface from Chang'e series of lunar gamma-ray spectrum measurement experiments, the CE1-GRS and CE2-GRS 緯 energy spectrum 2C scientific data were used. At first, the weak characteristic peak information is extracted from the spectral lines of the scattering background, and then the Chang'e series instrument spectrum is qualitatively analyzed. The results show that the CE1-GRS 緯 energy spectrum can identify 8 possible elements such as Al, O and so on. From the CE2-GRS 緯 spectrum, 10 possible elements, such as 10 kinds of possible elements, such as Al _ 2O _ O _ (Ti) and Ca, can be identified. 2) the closer the satellite orbit is to the lunar surface, the higher the energy resolution of the probe is, and the more precise the gamma-ray energy spectrum of the lunar orbit will be, which can obtain more accurate types and distribution characteristics of the lunar surface elements.

【正文快照】： 月球擁有眾多礦產(chǎn)資源,今后可供人類開(kāi)發(fā)利用。月球軌道γ能譜測(cè)量法是一種放射性探測(cè)方法,通過(guò)獲取月表發(fā)出的γ射線的能量和照射量率來(lái)確定月表元素種類和元素豐度。美國(guó)早在阿波羅登月計(jì)劃(Apollo Project)及“月球勘探者號(hào)”(Lunar Prospector)的探月任務(wù)中就采用了不同的，
