一、引言通常测量液体折射率是用临界角折射仪,如阿贝折射仪或普夫雷奇折射仪。这种临界角折射仪有一定的缺点,比如,当试样的折射率高于折射仪中棱镜玻璃的折射率时,则无法进行测量。本文所介绍的这种方法对测量试样的折射率却没有这个限制。而且使用的装置非常简单。
I. INTRODUCTION Liquid refractive index is usually measured with a critical angle refractometer, such as Abbe refractometer or Pflec refractometer. This critical angle refractometer has certain disadvantages, such as the inability to measure when the refractive index of the sample is higher than the refractive index of the prism glass in the refractometer. The method described in this article does not limit this to measuring the refractive index of a sample. And the device used is very simple.
