| 摘 要： | 根据分光计测定棱镜折射率的实验方法，提出了可以用分光计测定透明液体的折射率。从理论上推倒出最小偏向角及此时入射角、折射角满足的条件，并且得出光线通过平板玻璃时不会发生折射、只会平移的结论，由此结论可用平板玻璃构成一个内部充满待测液体的棱镜。最后通过实验论证了此方法的可行性。

| Abstract: | According to the laboratorial method which uses the spectrometer to measure the refractive index of prism,the article proposes that we can use the spectrometer to measure the refractive index of liquid.The minimum deflective angle,incidence angle,the condition which the angle of refraction must meet are derived from relative theory.Furthermore,a conclusion is drawn that the light beam can only move parallel instead of deflect when it passes through the parallel glass panel.By the conclusion,using the parallel glass panel to construct a prism inside which the liquid is full.The experiment shows that the method is doable. |
