finite nucleus meaning in English
有限核
Examples
- It is widely known that the relativistic mean field ( rmf ) method is rather successful in the researches of nuclear matter , finite nuclei and other fields . in our paper , we use the basical spirit of rmf in practical calculation
鉴于相对论平均场( rmf )理论在对核物质，有限核，以及其他领域研究中的运用取得了较大的成功，在本文的实际计算中，我们亦采用相对论平均场的思想。 - The contribution to the giant resonances from the currents of vector mesons are also examined , it shows that currents of vector mesons play an important role in collective giant resonances . by studying the properties of collective multipole excitations of nuclei , a general conclusion is that those effective lagrangians recently developed can well describe not only the nuclear ground state properties of finite nuclei , stable and unstable ones up to the nuclei drip lines , but also the collective excited states and giant resoancnes in doubly closed shell nuclei
通过对核的电多极巨共振性质的研究，我们发现现有的这些非线性的有效相互作用不但能够很好地描述有限核的基态性质，包括球形和变形核以及远离稳定线核，而且对一些双满壳核的集体激发态和巨共振性质也能进行合理地解释，包括巨共振峰的位置和中心能量。 - 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。
