When a REBCO tape carrying DC transport current is exposed to a perpendicular AC magnetic field with amplitude above certain value, flux could be triggered to traversing the superconducting tape. During the process, a biased DC response voltage, called the dynamic resistance voltage will be induced. In the paper, the calculation on the time-dependent dynamic resistance voltage was carried out by the H-formulation model implemented in the finite-element method (FEM) software package COMSOL Multiphysics. Fourier analysis on the waveform of dynamic resistance voltage was utilized to figure out the main components of the response voltage. The DC component, second harmonic component and ratio of the two components can reflect how the instantaneous dynamic resistance responds to the applied AC magnetic field and the DC transport current. The findings in the paper can be used to monitor the state of DC-carrying REBCO tapes subject to an AC magnetic field.

当承载DC传输电流的REBCO磁带暴露于幅度大于特定值的垂直AC磁场中时，可能会触发磁通量横穿超导磁带。在此过程中，将感应一个称为动态电阻电压的偏置直流响应电压。在本文中，由H进行了随时间变化的动态电阻电压的计算。有限元方法（FEM）软件包COMSOL Multiphysics中实现的混合配方模型。利用动电阻电压波形的傅立叶分析来找出响应电压的主要成分。直流分量，二次谐波分量以及这两个分量的比率可以反映瞬时动态电阻如何响应施加的交流磁场和直流传输电流。论文中的发现可用于监测承受交流磁场的直流承载REBCO磁带的状态。
