摘　　要：利用费马原理,以凹透镜为例推导薄透镜的成像公式,发现在成虚像的情况下,光程可以用一种较简单的等价方式替代.球面反射、球面折射成像都可以看作是薄透镜成像的特例,因此本文对薄透镜成像公式的推导和分析具有一定的实用性和通用性.By means of Fermat principle, the imaging formula of filmy lens is deduced from concave lens,and the optical path can be replaced by a simple and equivalent way when a virtual image is present. The imaging of spherical reflex and spherical refraction can both be regarded as a special case in the imaging of filmy lens. As a result, the deduction and analysis are of practical value and universality concerning the imaging formula of filmy lens.
