摘要:  本文简要介绍在Ｘ射线发射光谱测定法（ＸＲＳ）中的实验设备、研究方向和定量分析方法等的当前趋势．尽管ＸＲＳ是核技术应用的一个老的领域，但在各种形式的ＸＲＳ中，当前的进步是引人注目的．现在，ＸＲＳ是强有力的可实现的用于样品日常分析和物质精细结构研究的分析技术．This paper briefly introduces the developing trends of the experimental instruments,the study direction and the quantitative analysis methods on X-Ray Spectrometry(XRS).Although XRS is an old field in the application of nuclear technique, the recent progresses, in various forms of XRS, are dramatic. XRS is now a powerful and well establishedanalytical technique for routine analysis of samples and study of material fine structures.
