摘　　要：A screened hydrogenic model for 1 splitting （SHML） is used to calculate the Rosseland mean opacities of high-Z Au, Ta, Yb, Ho, C-d, Sm, Nd, Sn, Ag plasmas and mixtures of gold and these elements at high temperature （ T = 200 - 400 eV） and dense （ρ= 1 g/cm^3）. From the calculated Rosseland mean opacities of the mixtures, Au-Nd seems to be a better choice than other mixtures. Simultaneously, the reason that the mean opacities of mixture of Au-Sn decrease slightly when T = 400 eV is analyzed.A screened hydrogenic model for 1 splitting （SHML） is used to calculate the Rosseland mean opacities of high-Z Au, Ta, Yb, Ho, C-d, Sm, Nd, Sn, Ag plasmas and mixtures of gold and these elements at high temperature （ T = 200 - 400 eV） and dense （ρ= 1 g/cm^3）.
