【摘要】 对开普勒望远镜的放大率计算公式进行修正，结合实验验证，对视角直接比较法进行了改进。改进后的方法可以让实验者在物距较短的情况下精确测量自组望远镜的放大率，解决了学生在实验时遇到的实验空间受限、人眼观察距离受限的问题。更多还原

【Abstract】 We improved the direct-vision-comparison method through revising the calculation formula of the magnification of a Kepler telescope combined with experimental verification.The improved method allows the experimenter to accurately measure the magnification of the self-assembled telescope when the object distance is short, which solved the problem of limited experimental space and limited observation distance of the human eye encountered by students in the experiment.更多还原
