centre of curvature

基本解釋

The radius of curvature, centre thickness, and centering error of a lens can be meased by this method.
可對三種表面參數(shù)進(jìn)行測量，即曲率半徑、中心厚度和偏心差。
A series of factor such as the difference about the centre of figure and the shear centre, curvature radius, central angle is discussed.
對曲線梁中的剪、形心位置的差異以及曲率半徑、圓心角、預(yù)應(yīng)力大小、摩阻損失等內(nèi)力影響因素進(jìn)行了分析。

the point on the normal at a given point on a curve on the concave side of the curve whose distance from the point on the curve is equal to the radius of curvature
