本文分析了由于测试不慎而导致超导转变曲线产生畸变的因素:样品所处温场的不均匀、样品与温度计之间未达到热平衡、寄生电动势等。并提出了消除这些因素的方法。 This paper analyzes the factors that lead to distortion of the superconducting transition curve due to inadvertent testing: the temperature field in which the sample is located is not uniform, the thermal equilibrium between the sample and the thermometer is not reached, and the parasitic EMF and so on. And put forward ways to eliminate these factors.
