摘要：

Inhomogeneity of dilute magnetic CuFe thermocouple was studied. A set of test equipment was designed and constructed based on the double-medium method. The thermoelectric potential inhomogeneity of CuFe wires and NiCr wires were measured, and the results were analyzed with statistical methods. Through these analysis, and coupled with microstructure studies, it is possible to reveal the characters and the source of inhomogeneity of thermoelectrode, thus providing a way to improve the processing technic of CuFe thermocouple and to promote the application of the dilute magnetic copper-iron thermocouple, and creating a quality-control system for the manufacture of thermocouples, which is also suitable for other thermocouples. © 2017, Editorial Board of Journal of Huazhong University of Science and Technology.
