用垂直入射法测非等腰三棱镜的折射率

Measuring Refractivity of Irregular Triangular Prism with Method of Vertical Incidence

介绍了一种测量横截面为非等腰三角形的棱镜玻璃折射率的新方法,即用光线垂直入射的方法来测量非等腰三棱镜的玻璃折射率。其原理和公式比较简洁,操作方便,而且容易保证精度。

This article introduces a new method of measuring the glass refractivity of a prism with a cross section in the shape of irregular triangle,namely measuring the glass refractivity of an irregular triangular prism with the method of vertical light incidence.The author concludes that principle and formula are comparatively simple,the precision is easy to guarantee,and the operation is not complicated.
