袖山曲線の方程式

抄録

The authers tried to show the top line of sleeve by an improved formula, y =β³/αx^w+β²-h, of Witch's curvature, one of algebraical one, y =a³/x²+a², which was a part of circlein the top of curvature; consequently, it was very convenient for top line of sleeve.
We were confirmed that the curvature of our formula was fully fitted to actual top line of sleeve in clothing construction.
