平面的

A new method for ab initio energy partition is being developed in order to gain new insight into the nature of electron delocalization, and it is able to provide any molecule with a fragment MO basis set in which the π and σ systems have been separated out no matter whether molecule is planar or nonplanar as well as whether the π system is conjugated or cumulated.

我们的方法可以为任何一个共轭分子(无论是平面的还是非平面的，是含共轭双键的还是含累积双键的)，提供一个π与σ体系彻底分离的片断分子轨道基组。这个轨道基组不仅满足分子特殊的对称性，而且还具有确切的电子占据数。

The geoid is used to be regarded as the theoretic global vertical reference .The actual national height references are regional mean sea levels determined by tide gauge station. The difference between them is apparent. The satellite altimetry has developed as a kind of important space geodetic technique since 1970s.
