我们研究了在均匀电场和平行于x线的磁场强分量B的情况下，在静磁x线附近试验粒子的加速问题。加速粒子的能谱被发现解析在非相对论性的限制，表现出良好的协议与数值模拟。在高能量下，光谱以指数衰减，其特征能量与假设B =0的研究中发现的能量非常不同
We study the acceleration of test particles near a static magnetic x line with a uniform electric field and a strong component of the magnetic field, B ∥, parallel to the x line. The energy spectrum of the accelerated particles is found analytically in the nonrelativistic limit, showing good agreement with numerical simulations. At high energies, the spectrum decays exponentially with a characteristic energy very different from that found in studies assuming B ∥=0
