摘　　要：利用插值曲线,即三次样条插值和立方插值法来比较分析随机网络评审法中两个随机变量之间的相关性.经分析表明,立方插值不仅是分析相关性的实用曲线工具,而且利用Matlab所构造的函数有足够的光滑性、平顺性,且图像在考察变量的相关性时具有直观性的优点,因此对它的应用研究非常有价值.In this paper, we compare and analyse the relativity of two random variables in the Stochastic Network Assessment Method through interpolation curve, the interpolation curve is Spline interpolation and Cubic interpolation. The conclusion is that cubic interpolation is a practical curve tools in the research of relativity, and the constructed function is rather smooth and irregularity, the figure has the adavantage of intuitive, so its applied research is very valuable.
