提出了一种求解时变曲线交叉问题的快速傅里叶变换方法。详细描述了该过程，并通过计算一个双曲线，一维的例子来说明。给出并讨论了每条曲线的波函数和平均核位置和能量的时间演化。
We develop a unitary fast Fourier transform method for solving time dependent curve crossing problems. The procedure is described in detail and is illustrated by calculations for a two curve, one‐dimensional example. The time evolution of the wave function and mean nuclear positions and energies for each curve are shown and discussed.
