Study on Properties and Composition of Ancient Glass

Abstract

To help archaeologists to better study the ancient glass, open the mystery of the early of the silk road, also better protect the cultural heritage at the same time, this thesis will glass types, such as grain and color and whether the relationship between the surface weathering consider as a binary classification problem, and the characteristics of three types of value through the target code into numerical characteristics, build a gradient increase tree model, to score the importance of features, it is found that type has the greatest impact on weathering, followed by ornamentation and color. For the composition reduction of weathering points, this thesis transformed the problem of weathering point reduction into a mathematical problem of adjusting the characteristic values of weathering attributes. Firstly, this thesis checked the changes of the composition, and established a prediction model for the composition reduction of the weathered sites based on the qualitative assumption that "the sum of the composition contents remains unchanged" and the characteristic equation of the weathering attributes. Finally, the reduction calculation of the weathered sites was carried out.
