摘　　要：在假设任意形状类圆均质刚板的转动惯量为其周长和面积的函数基础上,提出了一种计算绕垂直其板面质心轴转动惯量的新的近似方法,并讨论了几种典型算例.结果表明该方法简单而有效.The paper presents a new method of calculating the rotational inertia of an arbitrary shape similar-circle plane uniform rigid around the perpendicular center-of-mass axis, by assuming that the rotational inertia is a func- tion of its areas and perimeters. As example, the classical cases are solved using our method and are compared with those by other method.
