density dependent meaning in Chinese
密度制约的,密度依赖的
Examples
- The nucleon dbhf self - energy in the nuclear medium , therefore , can be calculated with the g matrix in the relativistic hartree - fock approximation . with the calculated nucleon self - energy in the dbhf , we extract nucleon effective interactions hi the framework of the relativistic mean field theory ( rmf ) , which contains the effect of the nucleon - nucleon short - range correlation and information of the isospin structure . applying the effective interaction , which is composed of density dependent meson - nucleon coupling constants , we study the properties of finite nuclei and come to some useful conclusions
本文应用相对论dirac - brueckner - hartree - fock ( dbhf )方法，利用新的g矩阵分解方式g = v + g ，用g矩阵在相对论hartree - fock近似下，即等效的dbhf方法，系统地讨论了对称、不对称核物质及中子物质的性质，利用对称及不对称核物质中自能的dirac结构，我们提取出含有核子-核子短程关联效应和同位旋结构信息的有效相互作用介子耦合常数，并对有限核的性质做了详细的讨论，得到不少有意义的结果。 - The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent . it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger . we compare our results with those in a simple method , where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy
首先我们要求在每一个密度及各种不对称系数的核物质中，相对论平均场（ rmf ）计算出的核子标量与矢量自能与dbhf计算出的标量与矢量自能一致，从而得到在rmf下的密度依赖的有效介子核子耦合常数，包括同位旋标量介子。
