薄透镜焦距测定实验的误差讨论

ERROR DISCUSSION OF THE CXPERIMENT IN MEASUREMENT OF A THIN LENS FOCAL LENGTH

在现行的普通物理实验教材中,薄透镜焦距测定是理工科大学生的一个重要的必修实验,而对薄透镜焦距测定误差的讨论可以说是众说纷芸,没有较统一的看法,这给教学带来了不必要的混乱。为了有利于实验教学,我们对薄透镜焦距测定实验中的误差估算、光心引入的误差、测焦距误差最小的条件等几个方面作初步的探讨。

Among the university text-book of physical experiment, the experiment in determination of a thin lens focal length is a very important regnircd experiment for science student. error disscussion of the expesiment has many of opinions, there is no unified opinions. Of course it brings unnessary confusion, In order to benefit the teaching of the experiment. We make a initial discussion about, such as the error estimate and optical centre error among determinatcd experiment of a thin lens focal length.
