摘　　要：讨论R(黎曼)积分的特征和意义,旨在引导学生了解R(黎曼)积分的来龙去脉,掌握两类积分之间的内在联系和区别,从而为数学建模打基础,为分析陇南电子商务助力乡村振兴等数据提供理论支撑。As one of the two major components of calculus,the integration in Higher Mathematics includes Indefinite integral and Definite integral(Riemann Integral,referred to as R integral),which are introduced from two different viewpoints.Generally speaking,Indefinite Integral regards the integration as the inverse operation of differential operation,while Definite integral regards it as a kind of special form of sum limit.In order to guide students to understand the context of R integral and master the internal relationship and difference between the two types of integral,the present paper discusses the characteristics and significance of R integral,thus laying a foundation for mathematical modeling and providing theoretical support for the analysis of data in Longnan′s E-commerce development that helps rural revitalization.
