摘要
蔗糖溶液原本是无色透明的溶液,在偏振片的帮助下,可以使蔗糖溶液呈现出多彩的颜色。本文利用偏振片这一特性,观测在不同浓度下蔗糖溶液分光能力的差异,追踪蔗糖溶液在酸性条件下的水解过程,并介绍了实验现象背后的科学道理。
Initially colorless and transparent,the sucrose solution exhibited a stunning array of colors when viewed through a polarizer.This study utilized polarization characteristics to explore the variations in beam split capacity among different sucrose solution concentrations,while also tracking the hydrolysis process of sucrose under acidic conditions.The paper further elucidates the scientific principles underlying these experimental phenomena.
