本文详细研究了在Dungey磁场中辐射带电子与斜向传播哨声模式合唱波共振相互作用的共振区。Dungey磁场的参数为均匀南向行星际磁场强度（IMF）Bz或等效的D=（M/Bz，0）1/3（其中M是偶极子的磁矩，Bz，0是垂直于偶极子赤道面的均匀向南IMF）。采用背景磁场模型可以大大修正共振区的确定。与D = 50（非常接近偶极场）的情况下的结果相比，200 keV的电子与合唱波相互作用的共振区域的纬度覆盖范围往往变得更窄的较小的D值，无论赤道俯仰角，共振谐波，和波的法线角。相比之下，1 MeV电子的共振区域往往具有非常相似的空间长度沿着场线的各种邓吉磁...
The resonance regions for resonant interactions of radiation belt electrons with obliquely propagating whistler-mode chorus waves are investigated in detail in the Dungey magnetic fields that are parameterized by the intensity of uniform southward interplanetary magnetic field (IMF) Bz or, equivalently, by the values of D=(M/Bz,0)1/3 (where M is the magnetic moment of the dipole and Bz,0 is the uniform southward IMF normal to the dipole’s equatorial plane). Adoption of background magnetic field model can considerably modify the determination of resonance regions. Compared to the results for the case of D = 50 (very close to the dipole field), the latitudinal coverage of resonance regions for 200 keV electrons interacting with chorus waves tends to become narrower for smaller D-values, regardless of equatorial pitch angle, resonance harmonics, and wave normal angle. In contrast, resonance regions for 1 MeV electrons tend to have very similar spatial lengths along the field line for various Dungey magnetic ...
