摘　　要：一种新型结构的四引线金属壳线绕铑铁电阻温度计已经研制成功，这种温度计具有尺寸小、使用温区宽的特点，同一批温度计具有较好的互换性．本文介绍了这种温度计的结构、Ｒ－Ｔ特性、自热效应、稳定性和互换性，讨论了少数点标定和内插方法．Abstract A new type of rhodium-iron resistance thermometer has been developed. The wire-wound thermometer has a nominal resistance of 50Ω at the ice point and is designed to be used over the temperature range from 1K to room temperature. The resistance-temperature chatacteristies,selp-heating effect and stability of the thermometer have been studied in the range. This paper also gives the interchange abilities for some cases.
