| 摘 要： | 本文采用自己设计的光路,根据关于各向异性材料的几个弹性光学系数的定义,推得了它们与干涉条纹变化数的关系。以聚碳酸脂、环氧树脂及有机玻璃为例,测量了它们沿主应力σ_1及σ_2方向的折射率随外力的变化规律,从而完全得到了与它们有关的几个弹性光学系数。

| Abstract: | An experimental set-up is designed to determine the general relation between elasto-optical constants and interference fringes of anisotropic materials.As examples,the rela- tions between applied forces and refractive indexes in the direction of principal stresses for mate- rials such as polycarbonat,epoxy and plexiglass are studied,and the elasto-optical constants are measured. |

| Keywords: | photoelastic material elasto-optical constant stress-optical constant optical-anisotropic constant material fringe constant |
