摘　　要：文章从实际应用出发,给出低阶的有理插值函数的简便构造方法;利用叠加思想及一元向量Lagrange插值公式,给出一种便于操作的有理插值函数方法;该方法灵活、简便,可根据需要构造所需要类型的有理插值函数。A simple method of constructing low degree rational interpolation functions is meaningful in view of the practical application. A method of rational interpolating functions which can be operated easily is presented on the basis of the superposition thought and univariate vector Lagrange interpolation formula. The method is so flexible and simple that whatever types of rational interpolating functions which are needed can be constructed.
