摘　　要：一道经典习题，因对平行于透镜主轴的光线经透镜折射后形成亮斑的差异认识不足，被误讲多年．本文以实验为依据，对其中的问题精准剖析．It is a classical exercise. Because there is a lack of awareness to the difference of the bright spot formed by the ray of light parallel to the main optical axis lens, which is refracted through the lens, and it has been misexplained for years. Based on the experiment, this paper analyzes the problem.

关 键 词：习题 凸透镜 凹透镜 亮斑 光斑
