将求解任意势中波函数与转移矩阵技巧相结合，给出计算穿越任意势之透射系数的一种简单数值计算方法．该方法被应用于抛物势和电场中的双垒势，计算所得透射系数与采用多阶势近似所得结果相符．还给出这两种情形在共振态时的波函数．
A simple numerical method for calculating the transmission coefficient through any potential is given by combining the wave function in any potential with the transfer matrix technique. This method is applied to the dipole potential in the parabolic and electric fields. The calculated transmission coefficient is in good agreement with the results obtained using the multi-order approximation. The wave functions of these two cases at resonance are also given.
