用量子理论新方法研究光的双缝衍射实验现象, 首先用光的量子理论计算光在缝中双缝衍射的波函数, 再由基尔霍夫定律计算光的衍射波函数, 由衍射强度正比于衍射波函数模方, 从而得到光双缝衍射强度的解析式, 把量子理论计算结果和经典电磁理论计算结果以及与实验数据三者进行比较, 发现量子理论结果与实验数据符合更好, 而经典电磁理论计算结果与实验有一定偏差.从而说明量子理论更能精确解释光的衍射现象.该方法还可进一步研究光的单缝、多缝以及光栅衍射的实验现象.

In this paper, the light double-slit diffraction with quantum theory approach is studied. Firstly, the light wave function in slits is calculated, and the diffraction wave function is obtained with Kirchhoff′s law.The diffraction intensity is proportional to the diffraction wave function da party. Futhermore, the intensity formula of light double-slit diffraction is obtained; by comparing the quantum theory calculation results and classical electromagnetic theory calculation results and the experimental date, it is found that the calculate result of quantum theory is in accordance with the experment data, but the classical electromagnetic theory calculation result with the experiment date has certain deviation. So, the quantum theory can explain the light diffraction more precisely.The proposed method can also further study the light of the single slit,many slits and grating diffraction experiment phenomena.
