摘要

提出了计算折光系数nR的新公式。这个公式是用作者开发的普朗克粒子模型推导出来的。新公式用于计算水和糖溶液在不同温度和/或波长下的nR。在波长为361.05 ~ 632.80nm的10 ~ 60°C范围内，计算出的nR值与已知的nR值的平均差异为0.033%;对于葡萄糖、果糖和蔗糖溶液，在20℃和589.00nm下，干物质含量在10 ~ 40g/100g之间，分别为0.047%、0.029%和0.087%。

Calculation of refractive index of light in water, glucose, fructose and sucrose solutions

A new formula to calculate refractometric indexes nR is presented. This formula was deducted using a Planck dimension particles model developed by the author. The new formula is used to calculate nR for water and sugar solutions at various temperatures and/or wavelengths. The average differences, between calculated and known nR values were: 0.033% for water from 10 to 60°C and wavelengths between 361.05 and 632.80nm; and 0.047%, 0.029% and 0.087% for glucose, fructose and sucrose solutions, respectively at 20°C and 589.00nm, between 10 g and 40g/100g dry substance content.
