【摘要】 基于"固体与分子经验电子理论"（EET）,分析了Cu、Ag、Au的价电子结构,计算了一组表征金属单质性质的价电子结构参数统计值E′_A,T′_m,利用价电子结构参数统计值讨论了Cu、Ag、Au的熔点问题。计算结果表明,E′_A值越大,其对应金属的熔点越高,且E′_A的变化趋势与实验相吻合;Cu、Ag、Au熔点的统计值分别为T′_m^Cu=1 351.0 K、T′_m^Ag=1 126.2 K、T′_m^Au=1 305.0 K,相应的实验值偏差依次为0.41%、8.82%、2.33%,研究结果与实际符合较好。更多还原

【Abstract】 Based on the empirical electron theory of solid and molecules（EET）,the valence electron structures of Cu,Ag, and Au were analyzed.The statistical values of valence electron structure parameters E’_A and T’_m,which characterize the properties of metal single element,were calculated.Furthermore,melting points of Cu,Ag and Au were calculated by the value of T’_m and E’_A.The calculations results show that the melting point of corresponding melt is higher when the value of E’_A is bigger,and the change trend of E’_A in accordance with the experiment.The statistical values of melting point of Cu,Ag and Au were T’_m^Cu=1 351.0 K,T’_m^Ag= 1 126.2 K,T’_m^Au= 1 305.0 K,respectively.The corresponding deviation of experiment values are 0.41%,8.82%,2.33%.The research results agree well with real situations.更多还原
