mean curvature of surface

基本解释

Integral absolute mean curvature is introduced to describe average curving of an orientable closed surface.
引入积分绝对平均曲率来描述可定向闭曲面的平均弯曲程度。
It is presented that the more the surface of the progressive lens becomes closer to spherical by the process of mean curvature flow, the more the astigmatism is smaller.
采用平均曲率流方法使镜片渐进表面上符合设定条件的区域更加趋近于球面，从而减小镜片表面该区域处的像散。
This paper is to study local analytic properties of offset surface and gives its first and second fundamental forms as well as the concret expressions of Gaussian curvature and Mean curvature.
研究了等距曲面的局部分析性质，给出了等距曲面第一、二基本形式，平均曲率，高斯曲率的具体表达式。
