摘要
阐述了平面图形绕坐标轴旋转产生的旋转体体积与形心坐标之间的联系,在此基础上把它推广到绕任意直线旋转的情况,并得出求旋转体体积的一般公式。
This article daborates the connection between the volume of solids of rotation produced by plane figures encircling coordinate axes and areal coordinates, introduces its application to plane figure encircling an arbitrary beeline, and presents the general expression of volume of solids of rotation.
