High Potassium Glass, Lead Barium Glass, Spearman Correlation Coefficient, Principal Component Analysis.Abstract
To compare the differences in chemical composition correlation between high potassium glass and lead barium glass. Firstly, the Spearman correlation coefficient was used to observe whether there is a correlation between different chemical components. If there is a correlation, the degree of correlation has been indicated. At the same time, principal component analysis was used to reduce the dimensionality of 14 chemical composition indicators for high potassium glass and lead barium glass. The principal components corresponding to the characteristic values with a cumulative contribution rate of over 80% have been taken, and the meanings represented by these principal components have been explained. The specific differences in the correlation between the chemical composition content of different types of glass products have been studied, revealing the differences in the production processes of high potassium glass and lead barium glass.
