单电子双缝及多缝衍射的定量分析

A Quantitative Analysis of Two-slit and Multiple-Slit Diffraction of Single Electron

以单电子的双缝和多缝衍射为例 ,用费曼的路径积分理论对量子衍射态进行了定量分析 ,方法简单、明了 .

The quantum interference effect and diffraction effect have been widely applied in modern technology.In this paper the two slit diffraction and multiple slit diffraction of a single electron are taken for example,Feynman's path integral theory is used to analyse quantitatively the electron diffraction state.This method is brief and clear.
