摘　　要：在解三次样条函数时,最后都要归结为求解三对角型方程组。根据此类方程组的特点,该文介绍了一种追赶法,推导了使用这种方法的消元过程和回代过程,并给出了求解此类方程组的通用C语言程序,大大地节省了计算机工作量和计算机存贮单元。The method of solving the cubic spline function can be finally included in solving tridiagonal type equation group. According to the characteristic of such equations, this paper introduces a method named Chase-after, by which the processes of elimination and back substitution are derived, and also offers the general C language program applied to solve such equations. Computer workload and storage to solve such equation. Computer workload and storage unit are greatly saved by the employment of Chase-after method.
