摘要
给出了运用定积分水平面图形绕任一直线旋转一周所产生的旋转体体积及侧面积的计算公式，并就旋转平面的不同情况，分别用Ｇｕｌｄｉｎ第二定理及积分学的微元法思想给出详细的证明．
Give formulae to calculate volume and side area of a kind of revolutionusing difinite integral that the solid of revolution is prduced by a face(above the line) rotating around any line,and give the detailed proof of them,using Guldin 2th Theorem and the analysis idea about different cases of the rotating face.
