针对等边三棱镜顶角不精确为60°,两个底角不相等的情况,对三棱镜折射面成像规律进行了研究,得出了成像的普遍规律,为精确测量三棱镜顶角提供了理论基础及实验方法。

Aiming at the instance that the two bottom angles aren't equal to each other when the inaccuracy of the vertex angle of an equilateral prism is 60(,this paper makes some researches on the imaging rule of prism refracting surface, deduces the general rule of imaging and offers a theoretical basis and experimental method for accurately measuring the vertex angle of a prism.
