对溶液法测定偶极矩实验中单位制的思考

College of Chemistry & Materials Science, Northwest University. Xi'an 710127, China

Received Date: 3 September 2021

溶液法测定偶极矩是大学物理化学的一个经典实验。尽管实验操作简单，但是数据处理相对复杂。表示实验原理的公式基本都采用电磁学中的高斯单位制(Gaussian units)，这对于几乎只学习了国际单位制(SI)的化学背景学生的理解额外增加了难度。本文介绍及比较了两个单位制下的实验原理的公式，并自然得出通过实验数据计算偶极矩的最终公式系数及其中各物理量的量纲。
- Dipole moment,
- Solution method,
- Gaussian units,
- SI units
