【摘要】：月球表面的元素豐度是研究月表物質(zhì)分布的基礎(chǔ)數(shù)據(jù),可以提供月球地質(zhì)演化歷史的重要信息。探月工程"嫦娥二號(hào)"衛(wèi)星搭載了一臺(tái)X射線譜儀,自2010年10月1日發(fā)射以來(lái),獲得了豐富的觀測(cè)數(shù)據(jù)。在X射線譜儀長(zhǎng)達(dá)7個(gè)月的對(duì)月球觀測(cè)期間,發(fā)生過(guò)多次太陽(yáng)爆發(fā)。文中利用2011年2月16日9時(shí)一次太陽(yáng)M級(jí)爆發(fā)事件時(shí)X射線譜儀的觀測(cè)數(shù)據(jù),建立了定量反演元素豐度的方法,獲得了月球正面風(fēng)暴洋地區(qū)Mg、Al、Si、Ca和Fe的含量。通過(guò)各區(qū)域的元素含量比較,從風(fēng)暴洋南部沿飛行軌跡向北,Si含量逐漸升高,這種差異可能反映了不同時(shí)期玄武巖漿的成分差異。Ⅱ區(qū)域的Fe含量高于其他5個(gè)區(qū)域,但Ca、Mg、Al含量低于其他5個(gè)區(qū)域,說(shuō)明II區(qū)域相對(duì)其他地區(qū)受高地物質(zhì)的混染影響較小。月球風(fēng)暴洋中6個(gè)探測(cè)區(qū)域的元素平均含量分別是Mg 7.3%、Al 8.4%、Si 15.8%、Ca 6.0%、Fe 18.6%。最后,分析了"嫦娥二號(hào)"XRS數(shù)據(jù)反演月表元素含量可能存在的誤差。
[Abstract]:The element abundance of the lunar surface is the basic data for studying the distribution of the lunar surface material, which can provide important information on the history of the lunar geological evolution. The lunar engineering "Chang 'e-2" satellite is equipped with an X-ray spectrometer, and has obtained abundant observation data since it was launched on October 1,2010. A number of solar bursts have occurred during the 7-month observation of the moon in the X-ray spectrometer. The content of Mg, Al, Si, Ca and Fe in the sea area of the lunar surface was obtained by using the observation data of the X-ray spectrometer at the time of the M-scale explosion at 9:00 on February 16,2011. Through the comparison of the elements in each region, the content of Si is gradually increased from the south of the storm to the north along the flight path, which may reflect the composition difference of the basalt slurry in different periods. The Fe content in the II region is higher than that of the other 5 regions, but the content of Ca, Mg and Al is lower than that of the other 5 regions, indicating that the mixed-dyeing effect of the high ground substance in the region II is small. The mean content of the elements in the six detection areas in the lunar storm ocean was Mg 7.3%, Al 8.4%, Si 15.8%, Ca 6.0%, and Fe 18.6%, respectively. Finally, the error of the element content of the monthly table element in the data of the "Chang 'e-2" XRS is analyzed.
