摘要
本文讨论了ｄ轨道常见曲面的各瓣封闭曲面绕其伸展轴的旋转对称性。证明了除ｎｄｚ２轨道外的其余四个ｎｄ轨道的各瓣封闭曲面不是绕其伸展轴的旋转曲面。
The rational symmetry of closed surfaces of the curved surfaces of d chitals on their expasion axes has been studied in the article. It has been proved in the article that each closed surface of four nd chitals except ndz2 chital is not the surface of revolution on its expasion axis.
