Geometry dictates that only two -, three -, four - and six-fold rotational symmetry can exist.

几何规定旋转对称只能以二次，三次，四次和六次存在。

That is impossible. Geometry dictates that only two-, three-, four- and sixfold rotational symmetry can exist.

然而几何学告诉我们，只有二次、三次、四次和六次的旋转对称是能够存在的形式。

The results show that the static stress and displacement states are symmetrical on opposite sides of the axis whether the sample is symmetry in geometry or not.

证明在静态情况下，几何对称试件和几何非对称试件的轴线两侧均具有对称的应力和位移分布状态；
