| 为了在通用电路仿真软件中快速展开对超导电路的仿真研究，根据实验室制作的MgB2/B/MgB2纵向约瑟夫森结的相关参数，建立了Multisim的电路模型，对约瑟夫森结的特性进行了研究，并利用这个模型建立了超导RSFQ电路中两种不同功能的分支器；在理论分析的基础上，对电路进行了瞬态仿真。仿真结果不仅很好地验证了理论分析，且表明了这种方法的高效性及仿真实时、清楚、直观的优点，可用于进一步对超导RSFQ复杂电路的研究。 |

| Abstract: |
| In order to rapidly expand the study of superconducting circuits in general circuit simulation software, according to the experiment data of MgB2/B/MgB2 Josephson junction prepared in our laboratory, a circuit model is established in Multisim, the simulation results comply with the measured property of the junctions. Based on the theoretical analysis, transient simulation for two different functions rapid single flux quantum (RSFQ) splitters is conducted. The simulation proves the simple and intuitive working process of the circuit, and verifies the theoretical analysis well. The results indicate that the simulator is a useful tool both in feasibility and efficiency for superconducting RSFQ circuits. |
