本文对“用交流四引线电阻法测量转变温度Tc——连续超导体出现多相转变台阶”一文报道的典型实验曲线中各转变台阶所包含的物理信息进行了进一步的分析、测量及计算,并描述了几个判别性实验:由此得出结论:样品自感所产生的感抗以及由于超导交流损耗和超导线母材等原因产生的阻抗是该法能测出连续多相Tc的主要原因. In this paper, we further analyze, measure and calculate the physical information contained in the typical experimental curves reported in the article “Measuring the transition temperature Tc by AC four-lead resistance method - Multi-phase transition step in continuous superconductor” Several discriminant experiments were conducted: From this, it is concluded that the inductive reactance of the sample self-inductance and the impedance due to the superconducting AC loss and the superconducting wire base material are the main determinants of the continuous heterogeneous Tc .
