摘　　要：为解决某些实际问题,需要引入逼近函数,常用的是样条函数。本文以三次样条函数为例,研究基样条法和三弯矩法的逼近程度,分析它们的优劣及二者的异同,以便在许多实际问题中更广泛地应用最佳逼近。To solve some practical problems, approximating function is needed. Spline function is usually used. By taking cubic spline function as an example, the study of the approximation of spline - based method and three - moment method and the analysis of their merits and their similarities and differences can be used in the wider application of best approximation in many practical problems.

关 键 词：样条函数 基样条法 三弯矩法 异同
