曲面

Even a young architect who has attained success like Ma Yansong is also criticized for imitation his heteromorphic style and curved surfaces are criticized for having imitated Zaha Hadid.

即使像马岩松这样已经步入成功的年轻建筑师，也面临着被指模仿的批评（他的异形和曲面风格被指模仿Zaha Hadid）。

The authors show that the hyperboloid of one sheet and the hyperbolic paraboloid are ruled surfaces.

作者证实：单叶双曲面和双曲抛物面是直线曲面。

We discover that under a general configuration the twist system of this mechanism belongs to the seventh special three-system, and all the twist axes are distributed on a hyperbolic paraboloid that is special and unusual and rarely studied. Under original configuration it belongs to the fourth special three-system.
