| Abstract | 首先通过引入电子朗道能级稳定性系数 gn 和 Dirac-δ 函数，给出在超强磁场下相对论电子压强 pe的表达式. 然后，讨论了中子星内部超强磁场的量子电动力学效应. 最后，选择中子星的外壳层晶格物质和外核中理想的 n-p-e (中子？质子？电子) 物质系统为代表，讨论了超强磁场对物态方程的影响效应，研究发现，在中子星“中子滴出密度”以下的晶格物质中，核素 (A, Z) 转化为核素 (A′, Z′) 时发生相变，超强磁场会使相变发生在较低的物质密度区域，理想的 n-p-e 物质总的压强随磁场强度的增加而增大. |
| Other Abstract | In this paper, we firstly deduced a modified formula for pressure of relativistic electrons in superhigh magnetic fields (SMFs) by introducing the electron Landau level stability coefficient gn and the Dirac -δ function. Then we discuss the quantum electrodynamics effects of SMFs on the phase space, spin polarization and paramagnetic magnetization of electron gas in strongly magnetized neutron stars. Finally, the lattice mater below the "neutron drop density" in the crust and the ideal n-p-e system in the outer core of neutron stars are selected as representatives, and the effects of SMFs on the equation of state are discussed in detail. It is shown that when the nuclide (A, Z) is converted to (A′, Z′) in the lattice below the "neutron drip-out density" in the neutron star outer crust, the phase transition will occur in a lower density due to the SMF effects, and the total pressure of an ideal np- e system will increase with the increase of the magnetic field strength. |
