基于Visual Basic的电子干涉、衍射模拟

Simulation of Interference and Diffraction of Electrons Based on Visual Basic

根据杨氏双缝干涉、光栅的强度分布函数以及德布罗意物质波的理论,采用蒙特卡罗中的舍选法对大量电子进行舍选,并在Visual Basic中的图片框中输出显示,从而达到在Visual Basic的环境下对电子双缝干涉、光栅衍射的模拟.通过此模拟,可以更加形象地理解电子的波粒二象性以及电子波是概率波,为教学提供方便.

According to the intensity distribution function of Young two-sit interference and diffraction,and the theory of De Broglie matter wave,the program selects the electrons in the way of Monte Carlo's acceptance-rejection sampling to show on the picture box in the Visual Basic program,resulting in the sima lation of two-sit interference and diffraction of electrons in the Visual Basic environment.It is helpful in teaching for students to vividly understand the wave-particle duality and probability wave.
