摘　　要：利用三阶WKB近似方法,探究了非线性电动力学中带有磁荷的规则黑洞的似正规模.分别讨论这类带有磁荷的规则黑洞中的Bardeen-class黑洞、Hayward-class黑洞和New-class黑洞,在有质量标量场扰动下的似正规模,分析标量场质量对似正规模频率的影响.结果表明,随着扰动标量场质量的增加,黑洞时空的振荡频率变快,但振荡的衰减速度则变慢,这说明似正规模在大质量场的粒子衰减较慢些.此外,研究发现,随着标量场质量的变化,似正规模频率的实部与虚部之间呈近乎线性的变化关系.Using the third-order WKB approximation method,the quasinormal modes of magnetically charged regular black holes in nonlinear electrodynamics were investigated.The study focused on the quasinormal modes of Bardeen-class,Hayward-class,and New-class black holes with magnetic charge under the perturbation of a massive scalar field,and analyzed the impact of the scalar field mass on the quasinormal mode frequencies.The numerical results indicate that as the increasing of the perturbing scalar field mass,the oscillation frequency of the black hole spacetime accelerates,while the damping rate of oscillations slows down,which means that the quasinormal modes decay more slowly for particles in a large mass field.Additionally,it was found that there is an almost linear relationship between the real and imaginary parts of the quasinormal mode frequencies as the scalar field mass varies.
