我们测量了国产常用低温热偶材料的绝对热电势率,给出了镍铬、金铁、铜和康铜从4.2到273 K的测量结果.根据材料的热电势率计算了这些热偶材料配对组成的热电偶的热电势率和热电势与温度的关系.结果表明与实验一致.
We measured the absolute thermoelectric power potential of commonly used cryogenic thermocouples in China and gave the results of measurement of Ni-Cr, Au-Fe, Cu, and Cu from 4.2 to 273 K. These thermocouple pairs were calculated according to their thermoelectric power potential The composition of the thermocouple thermoelectric power potential and thermoelectric power and temperature relationship. The results show that consistent with the experiment.
