摘要
根据元素、合金和化合物，特别是高温氧化物超导材料的一些新的实验结果，重新分析了Ｍａｔｔｈｉａｓ经验规律．发现碱金属、碱土金属元素发生超导电性的峰值出现在平均价电子数为２，５和７处，Ａ－１５化合物、碳和氨化合物超导转变温度的峰值出现在５和７处．对于分析Ｃｈｅｖｒｅｌ硫化物和氧化物超导体的特性，合理的方法是计算其平均化合价，二者Ｔｃ的峰值在２附近，处于同一区．
According to some new experimental results for elements, alloy and compounds, especially High-Tc oxide superconductors, Matthias experimental law has been re-analyzed. The analysis shows that the maximum value of superconductivity happenning is located at the average valence electron mumber 2, 5 and 7 for alkalin, alkalin earth and transition metal, 5 and 7 for A-15 compounds, carburet and nitride superconductors. For Chevrel sulfide and oxide superconductors, the reasonable method is to calculate the average valence, and their maximum value of To is at 2 in the same region.
