摘　　要：同位素测试技术是同位素研究的基础。新的测试技术的创立,新的测试仪器的研制,原有仪器设备和测试方法的改进是稳定同位素地球化学研究发展的依托。因此发展同位素测试技术始终是同位素地球化学研究的一个主要方面。文章介绍了同位素测试仪器设备、稳定同位素研究对象和测试方法、同位素参考物质的研制以及同位素绝对比值测量的研究现状及近年来的发展。概括起来,总的趋势是:快速化、精确化、微量化、微区化、多样化和标准化。Isotopic analytical techniques are experimental base of isotopic study. Establishment of new analytical techniques, development of new instruments and renovation of analytical methods and instruments provide firm support to the development of stable isotope geochemistry. Therefore, development of isotopic analytical techniques is always a major task of study on isotopic geochemistry.In recent years, new techniques and new methods appear continuously, providing enormous drawing force for development of isotopic studies. The progress of isotopic analytical techniques evolves many aspects. However, in generally, it includes: quick in action, improvement of precision and accuracy, development of micro and in situ analyses, and standardization. An overview is presented in this paper on the present status and prospects on these aspects.
