【摘要】 测定了0—60 KG范围内Cu+0.13％Fe-NiCr热偶的磁场效应。该效应与热偶的使用方法有关。在第一类用法中,没有观测到磁场效应。第二类用法中液氦温度,60 kG磁场下[E_H,T—E_O,T]/E_O,T=5.7％。更多还原

【Abstract】 The effect of magnetic field on emf of CuFe-NiCr thermocuple has been measuerd. It shows that the effect depends on the methods used. In some methods, no effect of magnetic field is observed and in others, the effect is not larger than 5,7% at the liquid helium temperature, at the magnetic field of 60kG.更多还原
