摘　　要：用相对原子质量、有效主量子数定义一个原子特征参数P.P不仅对基态原子及简单离子实现惟一性表征,而且与70种固体化合物中阳离子的标准摩尔规定熵Sm具有很好的相关性,相关系数为0.9996,预测值与实验值十分吻合.Atomic characteristic parameter P is defined in terms of the atomic weight and effective principal quantum number which has good selectivity and appears uniqueness for all the ground state atoms and their simple ions. P is highly correlated with standard entropies of 70 cations in solid compounds. The correlation coefficient is equal to 0. 999 6. Results predicted by means of the P are in good agreement with those of the experiment.
