摘　　要：凸透镜焦距的测量方法和不确定度评价已经有很多研究,本文着重研究测量方法,提出了应用实物成虚像、虚物成实像方法来测量凸透镜的焦距,并与实物成实像方法进行比较和分析。本文的实验研究拓展了透镜焦距测量的方法,同时更加深入研究了透镜成像的规律,开拓了实验思路。The measuring method of convex lens focal length and uncertainty evaluation has been a lot of research, this paper focuses on the study of measuring method,puts forward the application of real virtual image, virtual object to measure real method of convex lens focal length, the comparison and a- nalysis of real image method and physical. Experimental study on the expansion of the lens focal length measurement method, at the same time, more in-depth understanding of the imaging lens, broaden the experimental method.
