一种新的原子结构模型及其计算机演示

A Novel Model of Atom and Its Computer Visualization

通过引入电子素这一新概念,建立了基于薛定谔方程的新的原子结构模型——电子素模型.与传统模型相比,新模型更加贴近人们的日常经验,其中专门定义的电子素密度和流密度这两个量可以用来清晰地表示氢原子所处的各种状态(本征态和叠加态),而且容易进行不同的操作和应用,因而具有更强的可操作性.根据这个模型,人们可以形象地表述薛定谔方程的解,清楚地看到处于各种不同状态下的氢原子的图形,还可以看到它从一个本征态或定态跃迁至另一个定态之过程的动画演示.原子的一些性质或现象也可以由此更方便更直观地得以解释.因此,电子素模型可望有助于推进量子物理的教学和科研.

A novel model of atomic structure the electronium model, based on the Schrodinger equation, was developed by bringing in a new concept of electronium. The new model is much closer to our everyday experience with its two specially defined quantities, i. e. the electronium density and current density,which can clearly express various states of a hydrogen atom （eigenstates and superposition states）. Moreover,it has a much better operability as it can conveniently be operated and applied. In virtue of this model, the solutions of the Schrodinger equation can be visualized with computer, and it is possible that the pictures of various states of a hydrogen atom and animations of the transitions from one eigenstate or stationary state to another are distinctly demonstrated. Thus various properties or phenomena of the atom can directly and readily be explained. Therefore, it is expected that the electronium model should be conducive to improve the teaching and research of quantum physics.
