【摘要】：为设计一种合理的月壤主量元素无损分析方案,本文以CAS-1模拟月壤为研究对象,对美国Apollo样品常用的探熔珠法的制样过程进行了改进,提出了一种月壤样品主量元素无损分析的方案。分析结果显示,该方案可以在较低取样量(10~20mg)的条件下准确地获得月壤样品中的主量元素含量,分析精度与美国Apollo样品常用的探针熔珠法具有相同的精度。这一方案可为合理利用中国探月工程三期采集的月壤样品提供有益借鉴。
[Abstract]:In order to design a reasonable nondestructive analysis scheme for the main elements of lunar soil, this paper takes CAS-1 simulation of lunar soil as the research object, and improves the process of sample preparation of American Apollo sample by the method of probe beads, which is commonly used in the United States. A scheme for nondestructive analysis of major elements in lunar soil samples is presented. The results show that the principal element content in the lunar soil samples can be accurately obtained by this scheme under the condition of low sampling amount (10~20mg). The accuracy of the analysis is the same as that of the probe melting bead method commonly used in Apollo samples in the United States. This scheme can provide a useful reference for the rational use of lunar soil samples collected in the third phase of Chinese lunar exploration project.
