本程序基于约瑟夫森结的RSJ模型，对无微波辐照和微波辐照下约瑟夫森结的特性进行了数值计算求解，其中有微波辐照的RSJ模型求解采用了四阶龙格库塔方程函数，两种情况都给出了I-V特性曲线图（程序包中也附带），展现了量子化电压台阶。-This procedure based on the RSJ Josephson junction model, no microwave radiation and microwave radiation characteristics of Josephson junction has been calculated solving, in which microwave radiation has the RSJ model for solving a fourth-order Runge-Kutta equation function In either case, they are given IV characteristic curve chart (also included with the package), demonstrating the quantum level of voltage.
