英文: The relation of radius of curvature and error as well as formulas of increasing parameters on condition of constant error are diverted.The equation of the line on the center of approximate circular arc is obtained,and it can avoids the trouble that numeri
中文: 导出了曲率半径与逼近误差之间的关系和等误差条件下的参数递推公式,建立了通过逼近圆弧圆心的直线方程和圆心坐标计算公式.按这种方法用圆弧逼近平面参数曲线,不需要求解非线性方程组,避免了计算可能不收敛的麻烦,简化了非圆曲线的节点计算过程.
