摘　　要：光具有波粒二象性,从量子力学的几率波出发,利用描述微观粒子的波函数,导出了光的单缝和多缝夫琅禾费衍射光强分布规律,所得结果与波动光学中用惠更斯-菲涅耳原理给出的结论一致,此方法有利于学生对量子力学中波函数的概念和统计意义的理解,进一步认识光的本性。The characteristic of light is the wave and particle.From the perspective of probability wave in quantum mechanics,the thesis describes the wave function of microcosmic particle and derives the distributive law of light intensity of the single slit and multiple-slit fraunhofer diffraction by means of the probability wave.The result accords with that obtained through the Huygens-Fresnel Principle.This method could help students to understand the wave function concept and the statistical meaning of wave function in quantum mechanics and understand the essence of light.
