| 声学测温在日常生活、生物医学和工业生产等领域有着广泛的应用，对拓宽温度测量应用范围具有重要意义。本文以敏感元件是否直接与待测物接触对声学测温方法进行分类，分别阐述了超声内部测温、声表面波测温、声速法测温以及声共鸣法测温的基本原理、计算公式、主要参数；并介绍了各声学测温方法的主要代表性产品、实际使用情况和目前的应用局限性。通过比较分析目前声学测温方法存在的精度问题和测温难点，得出总结与展望，为继续优化发展声学测温技术提供参考。 |
| 英文摘要: |
| Acoustic thermometry is widely used in daily life, medical research and industrial production, with great significance to broaden the application range of temperature measurement. In this paper, the acoustic thermometry methods are classified according to whether the sensitive element is in direct contact with the object to be measured. Also, this paper describes the basic principle, calculation formula and main parameters of ultrasonic internal thermometry, surface acoustic wave thermometry, sound-velocity thermometry and acoustic resonance thermometry respectively. Next, this paper introduces the main representative products, practical application and current application limitations of acoustic thermometry methods. By comparing and analyzing the precision problems and difficulties of acoustic thermometry methods, the conclusions and prospects are drawn, which can provide reference for further optimization and development of acoustic thermometry technology. |
