基于Visual C++的电子光栅衍射模拟

Visual C++-based Simulation of Electron Diffraction Grating

根据光栅衍射的强度分布函数和德布罗意物质波理论,在Visual C++的环境下采用蒙特卡罗舍选法对大量电子进行舍选,从而对电子光栅衍射进行模拟.该模拟形象、直观,有助于学生理解电子的波粒二象性和概率波的概念.

According to the intensity distribution function of diffraction grating and the theory of De Broglie wave, electrons were selected by means of Monte Carlo＇s acceptance-rejection method to simulate Visual C＋＋-based electron diffraction grating. The simulation is vivid, intuitive and helpful to understand the wave-particle duality and the concept of probability wave for students
