According to the current situation and prospect of applying OET in substation automation, the opinion of digital electro-optical secondary circuit is given out.

结合光电传感器在变电站自动化系统中的应用现状和前景，提出了二次回路光电数字化的设想。

On the basis of the principle, the OET (orbital-energy topological index) was proposed by revising the valence electron distance matrix with the orbital energy.

根据该原理，利用价电子轨道能量对价电子距离矩阵进行修正。
