摘要

凸透镜焦距的不确定度评价和减小实验误差的方法已经有很多研究，本文着重研究如何最大发挥透镜的作用，通过合适的测量方法适应凸透镜焦距、光阑直径以减小实验误差，提出了导致实验误差的重要因素———焦深与透镜参数的关系，并研究了近轴光线对实验误差的影响。研究结果为减小实验误差提供了一种新的思路，同时更加深入地研究了透镜成像的规律。

Abstract:

There have been many studies on the evaluation of the uncertainty of the focal length of convex lensand the methods to reduce the experimental error.lt focuses on how to correctly select the appropriate focallength and aperture diameter of convex lens to reduce the experimental error,puts forward the important factorcausing the experimental error-the relationship between the focal depth and the lens parameters , and studies theinfluence of paraxial light on the experimental error.The research results provide a new way to reduce theexperimental error,and further study the law of lens imaging.

Key words: focal depth convex lens imaging focal length diaphragm diameter
