摘要：
旨在讨论基于音叉式石英晶振(石英音叉)的石英增强光声光谱技术最新进展及应用.从石英音叉的基本原理以及标准32.7 kHz石英音叉的局限性开始,介绍了新型石英音叉的设计及改进方案,然后依据石英音叉的振动模式,将其按照基频振动模式以及第一泛频振动模式进行分类并展开详细描述.此外,基于这些定制音叉的特性,介绍了它们应用于石英增强光声光谱气体传感领域的最新进展,阐述了基于新型定制石英晶振的石英增强光声光谱传感系统的稳定性以及可靠性.
This article aims to discuss the latest developments and applications of quartz-enhanced photoacoustic spectroscopy technology based on tuning fork quartz(QTF).Starting from the basic principle of the QTF and the limitations of the standard 32 kHz QTF,the design and improvement of the novel QTF are introduced.Then the vibration mode of the QTF is classified into the fundamental flexural mode and the 1st overtone flexural mode,and the detailed description is given.In addition,the latest developments in their applications in the field of quartz-enhanced photoacoustic spectroscopy gas sensing are introduced based on the characteristics of these novel custom tuning forks,proving the stability and reliability of the gas sensing system.
