本文用数值方法求解了欧姆电阻分流的电流驱动约瑟夫森弱连接结的初值问题的稳态解。结的非线性混频作用导致DC响应中的Shapiro阶跃，其中阶跃高度以混频频率为单位。混频器增益已被计算与广泛的参数值和内在的混沌观察时，夏皮罗步骤是普遍的。>
We have numerically solved the steady-state solutions of the initial value problem associated with a current-driven Josephson weak-link junction shunted by an ohmic resistance. The nonlinear mixing action of the junction leads to Shapiro steps in the DC response with step height in units of the mixing frequency. Mixer gains have been calculated with a wide range of parameter values and intrinsic chaos is observed whenever Shapiro steps are prevalent. >
