研究了行星际波状电流片对银河宇宙线太阳调制的影响。一个简单的模型，其中有一个阿基米德螺旋磁场方向上的电流片上方的一个方向和另一个方向以下的日光层磁场。电流片本身被认为是太阳风对一个表面的延伸，在太阳上，这个表面是一个倾斜角度为。阿尔法帽。太阳赤道。因此，两个磁扇区将被观察者在一个角度内看到。阿尔法帽。日射赤道观测证据支持这一基本图片的磁场。
The effect of a wavy interplanetary current sheet on the solar modulation of galactic cosmic rays is investigated. A simple model of the heliospheric magnetic field is used in which there is an Archimedean spiral magnetic field directed in one direction above the current sheet and another direction below. The current sheet itself is taken to be the extension by the solar wind of a surface which, at the Sun, is a plane inclined at an angle ..cap alpha.. to the solar equator. Hence two magnetic sectors will be seen by an observer within an angle ..cap alpha.. of the heliographic equator. Observational evidence is presented which support this basic picture of the magnetic field.
