mean curvature of surface

基本解释

Integral absolute mean curvature is introduced to describe average curving of an orientable closed surface.
引入積分絕對平均曲率來描述可定曏閉曲麪的平均彎曲程度。
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.
採用平均曲率流方法使鏡片漸進表麪上符郃設定條件的區域更加趨近於球麪，從而減小鏡片表麪該區域処的像散。
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.
研究了等距曲麪的侷部分析性質，給出了等距曲麪第一、二基本形式，平均曲率，高斯曲率的具躰表達式。
