摘　　要：颠倒温度表是一种特殊的玻璃水银温度表,可分为测量水温的闭端颠倒温度表和测量水深的开端颠倒温度表。由于其特殊的结构和制作方法,在现场观测时,当颠倒温度表取上来后,温度表示数仍为颠倒处当时的温度和深度,至今仍在海洋调查中使用。为了保证颠倒温度表测量数据的质量,颠倒温度表应经计量检定机构检定合格后使用。介绍了颠倒温度表的检定原理、检定设备和检定方法、并对检定结果进行了不确定度评定。Reversing thermometer is a special mercury thermometer, and it can be divided into the protected reversing thermometeris used to measure temperature and the non-protected reversing thermometer used to measure depth. For its special structure and making method, the reversing thermometer could hold the reading at the deployment depth when being taken up. It is stiU used in the ocean survey up to now. In order to ensure the quality of reversing thermometer measurement data, reversing thermometer should be verified by metrology institutes. The verification principle, procedure, and uncertainty assessment method of verification data for reversing thermometer were introduced.
