mean curvature of surface

基本解釋

Integral absolute mean curvature is introduced to describe average curving of an orientable closed surface.
引入積分絕對(duì)平均曲率來描述可定向閉曲面的平均彎曲程度。
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.
采用平均曲率流方法使鏡片漸進(jìn)表面上符合設(shè)定條件的區(qū)域更加趨近于球面，從而減小鏡片表面該區(qū)域處的像散。
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質(zhì)，給出了等距曲面第一、二基本形式，平均曲率，高斯曲率的具體表達(dá)式。
