摘　　要：本文分析推导了透镜的凹面反射成像与凹透镜焦距的关系 ,介绍了利用此关系较方便地测量凹透镜焦距的方法。The relation between the focal length of a concave lens and its reflective image properties is analysed and deduced.The method of measuring the focal length of concave lens conveniently by making use of the relation is introduced.

关 键 词：凹透镜 反射成像 焦距 推导 反射法
