摘要: 在室温和液氮温度下,压强在0-20kbar(1bar=105Pa)变化范围内,测量了NiCr-NiCu热电偶的压力热电势随压强的变化关系.测量结果表明:在室温和液氮温度下,压力热电势均随压强增高,在0.1K的温度测量精度、0-20kbar的压强范围内,压力热电势不会对温度测量带来影响.

Abstract: The pressure effect on the NiGr-NiCu thermocouple was measured at room and liquid nitrogen temperatures up to 20 kilobar. The results showed that the pressure effect on the thermo-emf of this thermocouple was enhanced by the pressure. From 0 to 20 kilobar and in the accuracy of 0.1 Kelvin the pressuer effect on the thermo-emf did not affect the temperature measurement.

Key words: high pz-essure, low temperature, NiCr-NiCu thermocouple, thermo-emf
