摘　　要：X射线光谱分析技术(X-ray spectrometry, XRS)的发展已历经100多年历程,其独有的无损、原位和微区分析特性与主成分准确定量分析能力,使其在自然探索、科学研究、技术进步和生产应用中,发挥了十分重要的作用。但XRS也面临灵敏度不足、轻元素分析困难、元素氧化态识别不易等困境和挑战。随着近年激发光源、探测手段、光学部件制备技术的发展和基本粒子物理学研究的深入,XRS技术在降低检出限、发展实验室型元素形态分析装置、进行轻元素μ子X射线发射光谱(μXES)分析等领域,呈现出了新的发展趋势,成为当前和未来一段时期内值得重视和关注的学科发展方向。Over more than 100 years, the development of X-ray spectrometry(XRS) has made great progress. Due to its unique analysis ability in nondestructive testing, in situ and micro-size analysis as well as accurate quantitative analysis of major components, XRS has played important roles in natural exploration, scientific research, technical progress and production application. However, the greatest challenges for XRS are insufficient sensitivity, difficulty in determination of light elements and identification of elemental species. In recent years, with the development of excitation light source, detection means and preparation technology of optical components as well as the in-depth research of elementary particle physics, XRS analysis technique has showed new development trend in some fields, such as reducing detection limit, developing new types of laboratory spectrometers to determine elemental species, and analysis of light elements by muonic X-ray emission spectrometry(μXES). Those studies have become the new trend of discipline development which should be paid attention at present and in near future.
