摘　　要：运用球面成像原理,应用物像同屏和物像异屏方法,采用透镜折反折和折折成像,测定双凸厚透镜的曲率半径和折射率,并利用焦距公式计算得双凸厚透镜的焦距.该实验测定方法,体现了透镜成像的过程,得到了双凸厚透镜曲率半径和折射率的计算公式,拓展了透镜光学参量测定的方法和途径.By adopting refraction-reflection-refraction and refraction-refraction imaging process,in which the object and image could be on the same screen or on separate screens,the radius of curvature and refractive index of thick double-convex lens were measured,and the focal length of the thick double-convex lens was calculated.The experimental method revealed the process of imaging,enriched the methods of determining the optical parameters of lens.
