摘要
介绍用节点法求解存在内部势Ｃｘｎ的一维无限深势阱问题的物理原理，给出了该问题的数值结果，证实用节点法解决存在内部势Ｃｘｎ的一维无限深势阱问题比用变分法和微扰法的精度更高，方法更简便．
The procedure and physical principle of solving one-dimensional infinite well with an internal potential Cx n by using node theorem and numeric intergral are introduced. Its numeric solution is given out. It shows that comparing with variational method and perturbation method, the node theorem is more effective for such problems.
