中文摘要	Using the multi-configuration Dirac-Fock self-consistent field method and the relativistic configuration interaction method with quantum-electrodynamics corrections performed by the GRASP code, we calculate the fine-structure energy levels of the ground-state configuration (1s(2)2s(2)2p(3)) of the nitrogen isoelectronic sequence, according to the L-S coupling scheme with atomic number Z up to 22. Based on the calculated results, we elucidate the mechanism of the orderings of fine-structure energy levels of D-2(3/2,5/2) and P-2(1/2,3/2) respectively, i.e. for D-2(3/2,5/2) orderings, the competition between the spin-orbit interactions and the Breit interactions; for 2P(1/2,3/2) orderings, the electron correlations, especially the electron correlations owing to the 2p(5) configuration interactions.
