摘　　要：采用分段圆弧逼近样条曲线，求出按圆弧弧长等分的 ｘ 坐标，再用样条函数计算相应的 ｙ坐标。Approach a spline curve by using subsections of circles, and divide the curve by the equal length of the subsection. Calculate the values of x-coordinate of the curve that is approached, and then solve the values of y-coordinate by using the original spline function. Finally divide the spline curve by equal arcs.

关 键 词：圆弧逼近 样条曲线 弧长等分 样条曲线
