Then, using vector analysis, you use rotational symmetry, and you get this next set.
但是当你使用矢量形式时，一种轮换对称的形式，你们会看到接下来这种形势。

Rotational symmetry is one of the important structural properties of shape analysis in computer vision.
旋转对称性是计算机视觉形状分析中的一类重要结构属性。

As special topic, we discussed cranking shell model, BCS method of pairing force, spin assignment of rotational spectra and inertia analysis and new development of identical bands.
