| Abstract: | There is certain relation between the quality of wine and its physical and chemical index.This paper firstly uses principal component analysis to set up mathematical model, determines main physical and chemical indicators of the wine by analyzing and processing the data, then uses surface fitting to obtain function relation between the wine quality and two main indicators of the wine and intuitively illustrates the influence of physical and chemical index on the wine quality by three-dimensional simulation. |
