物理公式中的比例系数

Scals Coefficient in Physical Formulas

从量纲理论来讨论物理公式中的比例系数取值不同的原因，并给出具体的分析方法。在物理公式的教学与学习中，有意识的注意比例系数的取值以及取不同值所代表的物理意义，可以加深我们对物理规律和公式的认识，增进对事物本质的洞察能力。

Dimensional theory is applied to analyze the different values of the scale coefficient in physical formulas, and the analytic methods are also offered. In teaching and learning physical formulas, special attention should be paid to the different values of the stale coefficient and their specific physical meanings as well in order to deepen our understanding of physics laws and formulas.
