考虑了存在阿尔芬漂移的情况下信噪比中的宇宙射线加速。考虑了宇宙射线压力的非线性冲击修正。结果表明，在存在放大磁场的情况下，加速粒子的光谱可能会变得相当柔和。
Cosmic ray acceleration in SNRs in the presence of the Alfvenic drift is considered. A nonlinear shock modification by the cosmic ray pressure is taken into account. It is shown that spectra of accelerated particles may be considerably softer in the presence of amplified magnetic fields.
