摘要
本文首先简单介绍了量纲分析中的齐次定理和∏定理,然后具体例举了量纲分析在大学物理热力学部分的教学应用.我们的求解过程是:分析例举可能相关的物理量;写出各个物理量的量纲表;分析量纲表,确定相关的物理量和独立量纲;设定无量纲量等式;列出量纲指数方程组并求解.
This paper briefly introduces the homogeneous theorem and the ∏ theorem in dimensional analysis,and then specifically cites the teaching application of dimensional analysis in the thermodynamics part of college physics.Our solution process is:analyzing and listing the possible physical quantities;writing a dimension table of all physical quantities;analyzing the dimension table,determining the relevant physical quantities and independent dimension;setting the dimensionless quantity equation;listing and solving the dimension index equations.
