摘　　要：微束X射线荧光(microbeam X-ray fluorescence,micro-XRF)光谱技术是近年来兴起的一种微束分析技术,以其灵敏度高、所需检材微少、检测精确、非破坏性等优点而得到广泛的应用,近年来micro-XRF在司法鉴定中的应用也逐渐增多。本文根据国内外近期micro-XRF在法医学应用方面的研究进展,概述了其在射击残留物、指纹显像、毒品来源及生产工艺等物证鉴别方面及其在犯罪现场分析等方面的应用。近年来智能、便携化的micro-XRF技术设备已经开始得到应用,相信其在法医学鉴定中将得到更广泛的普及和应用。Microbeam X-ray fluorescence （micro-XRF） spectrometry has been raised as an analytical tech- nique of microbeam during the recent years. With its advantages of high sensitivity, small sample re- quirement, high testing accuracy and non-destruction, the technique is widely utilized in forensic science. This review bases on recent researches at home and abroad, describes its applications including identifi- cation of gunshot residue, visualization of fingerprints, discrimination of drug source, production process, and other material evidences of analysis in crime scene. Thanks to the advances in technology, intelli- gent and portable micro-XRF equipment has appeared to be applied. It is believed that it may be more popular and frequent in administration of forensic science in the near future.
