摘　　要：本文从薄凸透镜的反射成象原理出发,定性地解释了为什么物光经透镜后表面反射形成的倒立等大的实象时,其物距、象距都小于透镜焦距;另外介绍了逆向光路的计算方法。最后,通过薄凸透镜的反射成象原理和逆向光路的计算,推导出测量薄凸透镜的光学参量的简便方法。From the reflection imaging theory of thin convex lens,this text explains why,when the object through the back face of lens forms the same size and headstand image,the object length and image length are both less tham the lens focal length;And this text introduces the calculating method of the converse light route.At last,from the reflection imaging theory and the calculating method of the converse light route,this test deduces the easy way to measure thin convex lens's optics parameter.
