摘　　要：严格推导了测定纤维双折射的色那蒙公式并给出相应的实验条件。根据双折射和旋光理论论证了消光角与旋光无关；运用色散理论导出双折射和消光角与人射波长的关系式，证实了色那蒙公式与实验结果付合得很好，由此，本文提出了对制定合成纤维双折射测定标准的建议。We have deduced the formula used in determining the double refraction in synthetic fibre and given the experimental condition of determination.According to the theory of double refraction and optical rotation, we conclude that the extinction angle depends only on double refraction effect and has no relation with optical rotation. Using the theory of dispersion we have deduced the relation retween doulbe re faction and extinction angle in synthetic fibre andthe wave length of incident light. We have proved that the formula conforms well to the experiment result. From this,we put fOCward a su ggestionin deciding the determination standard of double refraction in synthetic fibre.
