圆弧圆心 meaning in Chinese

arc center

With the new - simple method , the equation of circle - arc - enveloping curve are deduced . also the relationship between the arc radius , the radius of center distribution and the distance of centers is given to avoid undercutting
文中采用新方法推导出了圆弧包络线转子型线方程，还给出了避免出现根切现象的圆弧半径、圆弧圆心分布圆半径以及中心距三者之间的关系。
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
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
