radius of circular arc 中文意思是什麼
radius of circular arc
解釋
圓弧半徑-
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 numerical solution owns possibility of no convergence and simplifies node calculation of non - circular curve
導出了曲率半徑與逼近誤差之間的關系和等誤差條件下的參數遞推公式,建立了通過逼近圓弧圓心的直線方程和圓心坐標計算公式.按這種方法用圓弧逼近平面參數曲線,不需要求解非線性方程組,避免了計算可能不收斂的麻煩,簡化了非圓曲線的節點計算過程
