In situ measurements at heliospheric shocks show that inside the shock front large-scale electric and magnetic fields are accompanied with strong small-scale fields. Until recently, it was widely believed that particle dynamics is determined by the large-scale fields. During the last several years, claims have been made that the small-scale fields are of primary importance. Here we show that the large-scale fields govern the ion motion while both large- and small-scale fields are important for electrons.

激波前沿的大场与小场：对粒子运动的影响

对日球震荡的原位测量表明，在震荡内部，大的电场和磁场伴随着强的小尺度场。直到最近，人们普遍认为，粒子动力学是由大型场决定的。在过去的几年中，有人声称小规模领域是最重要的。在这里，我们证明了大型场控制离子运动，而大型场和小型场都对电子很重要。
