摘要

摘要我们报告了利用电阻模型计算约瑟夫森结的电流-电压特性（I-V 特性）。我们发现，I-V 特性对超导电流与结边界阶次参数相位差 (φ) 的依赖性偏离理想约瑟夫森结所特有的简单正弦特性是稳定的。研究表明，要分析约瑟夫森结中发生的过程，必须测量这些结中产生的光谱成分。

Current‒Voltage Characteristics of Nonideal Josephson Junctions

We report calculations of current‒voltage characteristics (I‒V characteristics) of Josephson junctions using the resistive model. The I‒V characteristics are found to be stable to deviations of the dependence of the superconducting current on the phase difference (φ) of the order parameter at the junction boundaries from the simple sinusoidal one, characteristic of ideal Josephson junctions. It is shown that to analyze the processes occurring in Josephson junctions, it is important to measure the spectral composition of generation from these junctions.
