摘　　要：文中讨论了ｄ~５离子自旋四重态和二重态对基态~６Ｓ立方零场分裂的影响机制。指出两者的影响是一种综合效应，不服从线性迭加原理；四重态的影响占主导地位；二重态对~６Ｓ态的影响是通过四重态的中介作用而间接实现的。对文献［１５］中作出的研究结论──二重态的贡献为主，四重态的贡献可以忽略──提出了疑议。The mechanism of influence of the spin quartets and doublets of a ds ion on thecubic zero--field splitting of its ground state 6S is discussed. It is indicated that theinfluence of the two sort of multiplets is a synthetic effect and does not obey the linearsuperposition theorem; the influence of the quartets plays a leading role; and theinfluence of the doublets on the 6S state is realized by means of the intermediate effect ofthe quartets. The conclusion, proposed by ref. 15, that the contribution of the doubletsis the major while the influence of the quartets is negligible has been criticized to bequestionable.
