| 摘 要： | 在计算机机辅助测试（CAT）中，所测得的数据一般为一系列的离散系统样数据，怎样将它恢复为不失真的连续光滑曲曲线并打全出呢？本文提出了三次样条插值函数的形成法及其局限性，并对三次样条插值提取出了改进方法，使测得的一系列离散点能形成光滑的曲线。

| Abstract: | the data that it was tested are commonly a series of discrete sampling data in CAT . How do this data can be converted into a smoothy curve seemly with no disorder and also make it print out? This paper presents a method which can do the conversion above the Function of 3order sampling interpolation. At the same time , This paper also presents the limitation of the method and its improvent. As a result, a very smoothy curve can be obtained. |
