主　　题：Valence HgBa2Can-1CunO2n+2+δ(n=1 2 3 4). 

摘      要：Valence of elements in HgBa2Can-1Cu_nO2n+2+δ（n=1, 2, 3, 4） （both argon and oxygen annealed samples） were calculated. The result indicated for both argon and oxygen annealed samples, Hg had the lowest valence for the highest Tc sample. For fixed n, the valence of Cu in oxygen annealed samples was larger than that in argon annealed samples, indicating that oxygen annealed samples produce more carriers than argon annealed samples.
