摘　　要：由于宇宙常数的存在,时空为渐近de Sitter(dS)的时空．文中将静态dS度规作为时空的近似刻画,研究了在此度规下的一个洛伦兹破缺的电动力学模型．通过张量的标架场分解的方法,得到了静态dS时空中的电磁场方程．另外,分别研究了静态dS时空中点电荷的静电场和圈电流的静磁场,并且同时讨论了在此模型下的洛伦兹破缺效应．We propose an effective Lorentz-violating electrodynamics model via static de Sitter metric which is deviated from Minkowski metric by a minuscule amount depending on the cosmological constant. We obtain electromagnetic field equations via the vierbein decomposition of tensors. In addition, as an application of the electromagnetic field equations obtained, we get the solutions of electrostatic field and magnetostatic field due to a point charge and a circular current loop respectively. We also make some discussion on the implication of the Lorentz violation effect in our electromagnetic theory.
