摘　　要：本研究利用智能手机、偏振片以及手动旋转镜架,改进马吕斯定律实验装置,解决了实验过程中偏振片退偏振、外界光线干扰以及两偏振片夹角测定不准确等问题,改进后的实验相对误差低,线性关系好,有效验证了马吕斯定律.In this paper,the smart phones,polarizers and manual rotating frames are used to improve the experimental device for verifying Malus’Law and solve the problems of depolarization of the polarizer,inaccurate measurement when external light interferes and the angle between the two polarizers is small.It reduces the relative error and better meets the linear relationship,thus effectively verifies Malus law.
