基于呼吸气体分析的疾病诊断技术，属于无损医学诊断研究范畴，是今后医学诊断的重要发展方向，将会在今后无损医学疾病诊断中发挥重要作用，尤其是在当下新冠疫情肆虐的背景下，对于无创、实时、准确性高的疾病诊断技术的需求更加迫切。针对呼吸气体诊断需求，在介绍腔增强吸收光谱技术基本原理和技术特点基础上，概述了腔增强呼吸气体诊断技术国内外发展历史及现状，并在归纳整理呼吸气体诊断特点的基础上，分析了今后腔增强呼吸气体诊断技术发展方向，可为后续技术的发展和应用提供参考。

Disease diagnosis technology based on human breath analysis, which belongs to the scope of non-destructive medical diagnosis research, is an important development direction of medical diagnosis in the future and will play an important role in non-destructive medical disease diagnosis in the future. Especially in the context of the current rampant new crown epidemic, the demand for non-invasive, real-time, and highly accurate disease diagnosis technology is more urgent. Based on the basic principles and technical characteristics of cavity-enhanced absorption spectroscopy, this paper outlines the history and current situation of the development of cavity-enhanced human breath diagnosis technology at home and abroad, and analyzes the future development direction of cavity-enhanced human breath diagnosis technology on the basis of summarizing the characteristics of human breath diagnosis, which can provide reference for the development and application of the subsequent technology.
