In order to investigate and develop numerical calculation method for Schr odinger equation, we apply the finite difference method to eigenvalue problems in quantum mechanics. 摘要为研究和发展薛定谔方程的数值计算方法，本文将有限差分法应用到量子力学求解薛定谔方程本征值问题。
To avoid aimlessness in choosing design parameters, the variable permission scopes were computed and protracted by applying numerical method. 为避免机构综合过程中设计参数选取的盲目性，利用数值计算方法确定并绘制设计变量的可取值域。
