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。In order to design a method for nondestructively measuring major elements of lunar soil,the CAS-1 lunar soil simulant has been applied for demonstration. On the basis of the analytical method which has been used for measuring major elements of Apollo＇s samples,a new nondestructive method for measuring major elements of lunar soil has been proposed in this paper. Analytical results indicate that this new method can precisely analyze major elements of limited amount of lunar soil samples（ 10- 20 mg）,with similar accuracy of the microprobe fused bead method applied for the Apollo＇s samples. This will be helpful for the rational study of lunar soil taken by the Chang＇E 5 in future.
