摘要
改进了测量液体色散的棱镜法,并用于测量水的色散,得到了与文献一致的结果．利用该方法测量氯化钠和葡萄糖在不同浓度下的色散曲线,按照Cauchy经验公式拟合实验数据,得到了拟合常数与浓度的关系．通过理论分析,实验规律得到了合理的解释．
Chromatic dispersal curves in sodium chloride and glucose solutions with different concentrations are measured with triangular prism method, According to Cauchy experimental formula, the relationship between some constants in the formula and the concentrations is obtained. After theoretical analysis, the results of our experiment are interpreted and a useful and simple rule is obtained.
