摘　　要：偏振光定量测量实验是高等学校开设的一个光学实验。在验证马吕斯定律实验中,两偏振片透振方向夹角较大时,测量结果和理论值比较吻合;但夹角较小时,测量结果和理论值差别很大。测量结果和理论计算值的偏差如此之大,难以达到较好的验证马吕斯定律的目的。本文就上述问题进行了深入研究,找出了引起测量偏差的主要原因,并提出了改进办法。The quantitative measurement experiment of polarized light is a verification experiment of Malus law in college.When the angle between the two vibration directions of polarizer is large,the experimental results coincide in the theoretical value;but when the angle is small,the experimental results are far different from the theoretical values.The deviation is so large,it is difficult to achieve the purposes of verifying Malus law.After depth research of these issues,the main reasons that cause deviation of measurement are identified,and the ways to improve are proposed.
