对于纯径向和螺旋磁场的情况，考虑了具有各向异性质子温度并允许扩展日冕质子加热的太阳风双流体模型。质子-质子库仑碰撞与螺旋行星际磁场一起被发现足以将质子气体中的热各向异性降低到与观测结果一致的值。获得了地球轨道附近的流速、数密度和质子温度的合理值。
A two-fluid model of the solar wind with anisotropic proton temperature and allowing for extended coronal proton-heating is considered for the case of a purely radial and of a spiral magnetic field. Proton-proton Coulomb-collisions together with a spiral interplanetary magnetic field are found to be sufficient to reduce the thermal anisotropy in the proton gas to a value in agreement with observations. Reasonable values are obtained for the flow-velocity, number density and the protontemperature near the orbit of the Earth.
