量纲分析的方法和实践——试论量纲分析在大学化学教学中的应用

Methods and Practices of Dimensional Analysis——On the Application of Dimensional Analysis in College Chemistry teaching

通过引入量纲的概念,阐述了量纲分析在一些数理经典公式与化学常数和公式中的应用,并用量纲分析澄清了化学概念中的一些问题。量纲分析可增强化学专业学生的总结归纳和逻辑分析能力,还可提高化学专业学生的学科素养。

By introducing the concept of dimensionality,the role of dimensional analysis in understanding some classic mathematical formulas and chemical constants and formulas has been explained,and some issues in chemical concepts have been clarified through dimensional analysis.Dimensional analysis can enhance the summarizing and logical analysis abilities of chemistry students,as well as improve their discipline literacy.
