| 摘 要： | 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增公式,建立了通过逼近圆孤圆心的直线方程和圆心坐标计算公式.按这种方法用圆孤逼近平面参数曲线,不需要求解非线性方程组,避免了数值计算可能不收敛的麻烦,简化了非圆曲线的节点计算过程.

| Abstract: | The relation of radius of curvature and error as well as formulas of increasing parameters on codition of constant error are divered,the equation of the line on the centre of approximate circular arc and coordinate formulas of the centre are built up.This method doesn't solve nonlinear equations and avoids the truble that numerical solutions own possibility of no convergence and simplifies node calculation of non-circular curve. |
