摘　　要：用通用软件Mathematica和简并微扰论计算了氢原子n=3~7能态在一对同方向电磁场中的能级分裂（不考虑自旋）.数值结果表明：在许多情况下,一级修正可以使能级简并完全解除,这时总体能级分裂不是等间距的;但在一定条件下,总体能级分裂是等间距的,此时能级简并不能完全解除,只分裂为3n-2个不同能级.现有文章的结论是欠周全的.By using the perturbation theory and Mathematica, the energy level splitting （ n = 3 - 7） of the hydrogen atom in the electric field and magnetic field of the same direction is calculated. The numerical results show that the degeneracy of energy levels （n = 3 -7 ） is completely removed in many cases, while the overall energy level splitting is not equidistant. But under certain conditions,the overall energy level splitting is equidisatnt, and the degeneracy of energy levels is not completely removed, the energy is only split into 3n-2 different levels. The result from some recent articles is not comperhensive.
