摘要
在Ｗａｌｅｃｋａ模型、热场动力学和相对论Ｄｉｒａｃ－Ｂｒｕｃｋｎｅｒ－Ｈａｒｔｒｅｅ－Ｆｏｃｋ计算结果基础上，研究了在不同核密度和各种温度情况下的核子相对论微观光学势及其相应的薛定谔等效势和平均自由程，计算结果表明，对于不同的温度，核子的薛定谔等效势与平均自由程随核密度变化较为敏感，而核温度对核子的薛定谔等效势和平均自由程的影响随着核密度的增加变大。
The relativistic microscopic optical potential,the Schrodinger equivalent
potenlial and mean free paths of a nucleon at finite temperature in nuclear matter with different nuclear density are initially studied on the basis of Walecka' s model, the
thermo-fielddynamics and the relativitic Dirac-Brueckner-Hartree-Fock approach. The
calculatted results show that the dependences of the Schrodinger equivalent potential
and mean free path of a nucleon on nuclear density are fairly sensitive and the
dependences on nuclear temperature become more sensitive when nuclear density is
larger.
