摘要
基于对量纲基本概念和量纲分析法基本原理的分析,探讨了量纲分析在物理实验中的应用.在物理实验教学中,采用物理量的量纲表示可以方便单位换算,利用量纲基本规则可判断物理公式的正确性,通过量纲的分析可使寻找物理量间复杂关系或规律变得简单.
Dimensional analysis is one of the important approaches in investigating physics problems.It gives facilities for conversion of units by the expression of dimensional relations among variables in physics experiment teaching, the estimation of the validity of formulae by basic rules of dimension, and simplify the complicated relations among variables.
