摘要
本文主要介绍了积分微元法的几点应用:在微元法的基础上,可用二重积分计算曲顶柱体体积和顶曲面的面积,可用曲线积分来求柱面侧面积,还可以统观二重积分和曲面积分.
In this paper, some applications of differential element method of integral are proposed. By means of differential element method, the volume of cylinder and the area of surface can be calculated by using multiple integrals ; the lateral area of cylindrical surface will be obtained through curvilinear integral. The relations between multiple integrals and surface integral are discussed on the basis of differential element method.
