The coaxiality tolerance assesses the deviation of the axis from the datum axis, while the radial run-out tolerance assesses the deviation of the circumference line from a coaxialcircle.
同轴度公差评估的是轴线相对于基准轴线的偏差,而径向跳动公差则评估的是圆周线相对于同轴圆的偏差。

By means of Cauipotential lines, exact formulas for calculating the characteristic impedance of the coaxial systems consisting of a circle and a N- resular polygon are derived in this paper.
