  1. There has been many papers to discuss the in - medium quark and gluon condensates in nuclear matter which use the models with su ( 2 ) l su ( 2 ) r sym - metry. now, we make use of the chiral model su ( 3 ) l su ( 3 ) n including the baryon octet to discuss the quark condensate < qq > in strange matter, where q is an up or down quark field. on the one hand, from the experimetal data, it is found that < qq > vac = - ( 225 25mev ) 3, on the other hand, with the hellmann - feynman theorem, quark condensate can be evaluated on the hadronic level. in this paper, we will investigate the quark condensate in strange matter with the chiral symmetry su ( 3 ) l x su ( 3 ) rspontaneous breaking lagrangian to obtain the variation of the quark condensate in the strange matter when the baryon number change. it can be applied to understand the neutron stars when the neutron star are considered to be constructed by the strange matter. because nertron stars are homogeneous and at very low temperature, we will use the mean - field approximation and zero temperature throughout this paper

At the other hand, we can perform the rrpa calculation with the continuum replaced by a set of outgoing single particle resonances, it indicates that the resonances in the continuum play an important role in the description of nuclear dynamical processes, such as collective giant resonances. energies, widths and wave functions of the single particle resonant continuum are determined by solving scattering states of the dirac equation with proper asymptotic conditions for the continuous spectrum in the r ' elativistic mean field theory. the relativistic regular and irregular coulomb wave functions are calculated numerically

    在進行相對論無規位相近似計算時將連續譜中所有的正能態用單粒子共振態來代替,並且在計算中採用單粒子共振態的真實寬度,利用這種方法我們計算了核的同位旋標量巨八極共振響應函數,並且和考慮了連續譜中所有正能態貢獻的結果進行比較,計算結果表明,連續譜中只考慮單粒子共振態對核的集體激發的貢獻時,給出的響應函數基本上能夠重現考慮了所有正能態貢獻時的計算結果,這說明了在核的集體激發中,連續譜中主要是單粒子共振態的貢獻。
  11. The relativistic random phase approximation ( rrpa ) is a relativistic extension of the random phase approximation for studying microscopically nuclear dynamical excitations and giant resonances. the consistency of rrpa calculations requires two aspects : first, it demands that the relativistic mean - field wave " function of nucleus and the particle - hole residual interactions in the rrpa are calculated in a same effective lagrangian. second, the consistent treatment of rrpa within rmf approximation requires the configurations including not only the pairs formed from the occupied fermi states and unoccupied stat es but also the pairs formed from the dirac states and occupied fermi states
