摘　　要：文中介绍了偏振光的特性及相关原理。利用偏振片产生偏振光并测量了光功率,利用得到的实验数据拟合了一个关于偏振片的旋转角度与光功率的经验公式。将经验公式与理论公式相对照,从一个新的角度验证了光马吕斯定律的正确性。The features of polarized light are introduced in this paper as well as the experiment process of detecting these features. In the experiment,polariods are used to create polarized light and the power of light is metered. Then according to the statistics collected in the experiment and fitted by sinusoid,a empirical formula is found. Finally,this formula is compared with the theoretical formula to testity the Malus law from a new aspect.
