摘要

我们计算了由电磁机制形成的星系宇宙射线的各向异性特征。该机制是基于感应电场和移动太阳风的规则磁场的共同作用。对于能量为10 GeV的宇宙射线，得到了以下结果：(1)矢量各向异性为0.4 ~ 0.6%，方向自西向东垂直于日地线；(2)张量各向异性具有双轴椭球的形式，其小轴沿行星际磁场方向。计算结果与实测结果相吻合。

Electromagnetic Mechanism for Formation of Galactic Cosmic Rays Anisotropy

We calculated the characteristics of the anisotropy of galactic cosmic rays formed by an electromagnetic mechanism. The mechanism is based on the combined action of the induction electric field and the regular magnetic field of the moving solar wind. For cosmic rays with an energy of 10 GeV, the following was obtained: (1) vector anisotropy of 0.4–0.6% is directed perpendicular to the Earth–Sun line from west to east; (2) tensor anisotropy has the form of a biaxial ellipsoid, the minor axis of which is directed along the interplanetary magnetic field. The calculation results correspond to the measurements.
