Theoretical study of electronic eqution of state for plasmas with transitional region

On the basis of the improved averaged atomic model,the distribution of the free electrons is dealt with by partial wave method in central field approximation to improve the precision of energy level and electron populations, The broadening of high electronic levels into bands is taken into account in a uniform approximation. Therefore,the precision of atomic inner energy and pressure is improved. As samples, the parameter of EOS of Mo, Au are calculated, respectively.
