通过使用原始模拟方案来研究高能电子的共振扩散过程，在该方案中，冷电子被视为流体，热电子被视为包括完全相对论效应的颗粒。当前的仿真方案使我们能够研究内部磁层中的谐振散射过程，这很难使用PIC代码研究。我们通过比较当前的数值实验和准线性理论在惠斯勒模式波和高能电子之间相互作用的情况下，通过比较当前的数值实验和准线性理论来研究电子分布的变化。他们的结果之间的差异表明，在逼真的血浆条件下对理论验证的重要性，与外部辐射带中观察到的参数相对应。
Resonant diffusion processes of high energy electrons are studied numerically by using an original simulation scheme where cold electrons are treated as a fluid and hot electrons are treated as particles including fully relativistic effects. The present simulation scheme enables us to investigate the resonant scattering process in the inner magnetosphere, which has been difficult to study by using the PIC code. We investigated the variation of the distribution of electrons through the resonant diffusion process by comparing the present numerical experiment and the quasi-linear theory under the same condition of the interaction between whistler-mode waves and high energy electrons. The difference between their results suggests the importance of the verification of the theory under the realistic plasma condition corresponding to the observed parameters in the outer radiation belt.
