摘　　要：用薛定谔方程求解电子在缝中的衍射波函数,用路径积分方法求解电子在缝外的衍射波函数,最终推导出衍射强度的关系式.理论计算结果和实验测得数据符合相当好,验证了量子理论方法能够精确解释电子的衍射现象.The electronic wave function in the slits is obtained by the Schrodinger equation,and electron diffraction wave function outside the slits by the strict solutions of path integral method.The diffraction intensity is proportional to the square of diffraction wave function.Then,the formula of electronic double-slit diffraction intensity can be obtained.It is found that the theoretical calculation result of quantum theory and the experimental measurement data tally pretty well.So,the method of quantum theory can explain electron diffraction phenomenon precisely.
