Ac-cording to the definition of the radial circular run-out error a mathematical model of the error has been established. 根据单一基准径向圆跳动误差的定义建立了该项误差的正交最小二乘评定数学模型。
The radial vibration of isotropic thin elastic circular plates is studied and the equivalent circuit is obtained. 摘要对各向同性弹性薄圆盘的径向振动进行了研究，得出了其等效电路。
