摘　　要：利用复变函数关于差商的表示法得出了偶次叠基样条插值误差的渐近展开式系数的简易计算法 ,并利用算符运算法给出了叠二次、叠四次基样条渐近展开式系数的递推公式。In this paper,A simply method for calculating coefficient of Asymptotic expansion form of even cardinal spline-on-spline interpolation is obtained by taking advantage of difference quotient expression methods of complex functions,and the recurrence formula of Asymptotic expansion form coefficient of twice and quadrtic cardinal spline-on-spine interpolation is resolved.
