丰富测透镜焦距实验的内容

Making experiment more contents in measuring of lens focal length

在普通物理光学实验中,焦距的测量通常使用单透镜作为待测透镜,但单透镜存在各种像差,会使测量结果的物理意义变得不清,对此本文提出了一些改进意见。

In general physics optical experiment, single lens is usually used as the object in measuring focal length. There are a number of aberrations in single lens, it makes the physical significance of result of measurement become ambiguous, therefore, improving proposal is given.
