摘　　要：在对传统平均原子模型(AAM1)作动态自由电子判据改进的基础上,在中心场近似下使用了带边界条件的正能态波函数,提高电子压强的计算精度,使得电子压强满足常态物理条件.作为算例,计算了Fe,Ni,Pb,Am的电子压强.On the basis of dynamic criterion for free electrons, a traditional averaged atomic model （AAM1 ） is improved in several aspects. The continuum radial wave function in central field approximation is normalized in a certain boundary condition. The contributions of the free electrons are dealt with in four parts to improve the precision of electron pressure. The condition of normal density is spontaneously satisfied. As samples electron pressure of Iron, Nickel, Lead and Americium are calculated and compared with the results other theories and experiments.
