摘要
根据固体物理电子气理论物理模型，提出了一个计算金属表面电子脱出功的计算公式对２３个主族金属元素电子脱出功的理论计算结果表明，计算值与实验值基本吻合（标准偏差仅为 １．０３ ｅＶ）；同时发现该理论计算值与电子脱出功实验值的关联结果优于
An effective method is presented for calculating the work function of solid metal atom, X, that is: X =-[Z*e2/(4πεr)]exp(Ksr), where 1/Ks is the Thomas--Fermi screening length, r is the covalence radius. For 23 main group metal elements, the calculated work functions, X, are agree well with experimental data (the standard error is only 1.03 eV). In addition, it is found that the calculated work function has a better linear relationship with the experimefltal work function than that of the Pauling's electronegative.
