利用坐标变换与微元法得到了空间曲线绕任一直线旋转所得旋转曲面∑的面积公式 ,以及由∑所围 (未封闭处加底圆盘 )
As to the space curve coils the arbitray right line and circles to obtain the rotational surface ∑, the body of rotational through ∑'s surround into(the part sealing off does not put the back plane disc), the integration formula about area of rotational surface and volume of the body of rotation are given by using coordinate transformation and Infinitesimal method.
