摘　　要：利用格林公式构造被积函数组,化二重积分为线积分,得到计算任意闭曲线边界的均质薄平板转动惯量的一般公式,并用该公式简捷地求出了教材上不常见的几种均质薄平板的转动惯量.A general formula for calculating the homogeneous thin plate rotation inertia with arbitrary closed curvilinear boundary is derived. We construct integrand group and change double integral into the Green formula, and then some infrequent examples are calculated by this formula tersely in the textbook.

关 键 词：格林公式 均质薄平板 转动惯量
