摘要
稀土化学键的共价性和４ｆ轨道在成键中的作用是化学界长期争论的问题之一。近年来的理论和实验研究结果表明，４ｆ轨道参与了稀土化合物化学键的形成，稀土化学键具有相当大程度的共价性。４ｆ轨道的参与比例和稀土化学键共价性成分的定量确定还需做大量的工作。
A controversial question has long been the role of 4f orbitals and the covalent characteristics of rare earth compounds bonds. The recont theories and experiments indicate that the 4f orbitals play a part in forming the rare earth compounds bonds and that the bonds are quite covalent. Too much is yet to be done in finding the accurate role and ratioes of the 4f oritals and the quantitative determination of the rare earth bond covalence constituents.
