| 摘 要： | The crystal structure stability as well as electric conductance of （Sr/Ca）2CuO2Cl2 compound with K2NiF4 structure was investigated up to 31 GPa using diamond anvil technique. It seems that （Sr/Ca）2CuO2Cl2 is quite stable under pressure but with obvious anisotropic compressibility. The equation of state （EOS） obtained shows relative large bulk modulus.
