再论周期表中的相对论性效应

ON RELATIVISTIC EFFECT IN PERIODIC TABLE AGAIN

简要地论述了多电子原子体系的主要相对论性效应,即相对论性收缩、自旋-轨道分裂和相对论性自洽扩展等。随着元素原子序数增加,上述效应的影响迅速增大,这是决定重元素及其化合物“反常现象”的主要因素。诸如某些重金属元素的“反常性”、特殊性、差异性和相似性均可用相对论性效应予以解释。

The article briefly discusses the essential relativistic effect of multi-electron atom, such as relativistic contract, self-spin splitting and relativistic selfconsistency expand etc.. The influence of this effect increases quickly with increase of atomic number. They are the main factors to determine the abnormal phenomena of heavy elements and their compounds. The abnormality, particularity, difference and relativism of some heavy metal elements all may be explained by means of relativistic effect.
