| Abstract: | The mathematical model of one of the main surfaces of a three-edge bronze arrow from QinshihVang's Army Vaults is first established in this paper by using stepwise regression analysis. Then,the geometric shape of the main surface is analysed, and the mathematical models of the other two main surfaces are obtained by using the rotation transformation of coordinates. Based on this, the mathematical models,of the three main edges are derived,and the convex trait of the main surface is quantitatively analysed. |
