摘　　要：为了弥补显微镜与偏光显微镜的组装实验在测量明视距离和读数方面的不足,提出一种利用现有实验仪器对实验进行改进的方案。利用目镜、物镜、半透半反镜组装成为显微镜,并对样品进行观察,对目前普遍采用的对明视距离的近似计算提出改进方法,设计计算放大倍率,并对读数测量尺进行了优化。利用偏振片的消光现象调节读数视野的明亮程度,达到提高实验精度的目的。In order to make up for the deficiency of microscope and polarizing microscope assembling in measuring and reading vision distance,this paper presents an improving scheme on the experiment by using the existing experimental instruments.Experiments use the eyepiece,objective lens,beam splitting mirror to assemble a microscope and to observe some samples,then give an improving method for calculating the distance of distinct vision to calculate enlargement ratio.This paper also provides the improvement of the measuring rules.The improving scheme points out a method of using the extinction of polaroid to adjust the brightness of visual field and to improve the experimental accuracy.
