在对材料进行的光学两波耦合实验中，观察到了非对称能量耦合现象，本文对此进行了分析。

In the two beam coupling experiment asymmetric energy transfer was observed and the phenomenon was analyzed.

这意味着如果他们对称，那么每根键的能量是一样的。

If it's symmetric, that means that each bond has exactly the same energy.

因此能量是呈放射状的，对称的，等效全向的辐射，向各个方向，因此很简单。

And so that energy goes out radially, symmetrically, isotropically in all directions, and so it's very easy.

Same bond, symmetric bonds means equal energy, which means equal links.

相同的对称的化学键意味着相等的能量，相同的联系。
