利用新近获得的子午面磁盔－电流片背景太阳风稳态解，对激波从盔底沿电流片方向往外传播时与磁盔间的相互作用进行了数值模拟研究，重要新结果是：１．磁盔的存在使受扰介质速度跃变中央出现下凹，随着激波传出磁盔区并沿电流片方向传播，速度下凹逐渐减弱以致消失；２．激波将磁盔拉长并把盔顶的环形（垂直赤道面）磁场带到行星际空间，成为行星际磁场南向分量的来源之一；３．５个太阳半径（Ｒ⊙）内的磁盔部分将出现精细结构，沿盔外边界形成两条高速带，以及马蹄形密度（亮）环形结构等．这些结果表明，太阳附近高速等离子体与磁盔间存在重要的动力学相互作用过程，对行星际空间的太阳风三维结构有重要影响．
Using the recently obtained steady-state solution of the meridional surface of the meridian magnetic helmet-current sheet, the numerical simulation of the interaction between the shock wave and the helmet when the shock wave propagates from the bottom of the helmet along the current sheet is presented. The main new results are as follows: 1. The presence of the magnetic helmet causes the center of the velocity jump of the disturbed medium to appear concave, and as the shock wave spreads out of the magnetic helmet zone and propagates in the direction of the current sheet, the speed concave depression gradually disappears; 2. The shock wave lengthens the magnetic helmet and brings the ring-shaped (vertical equatorial) magnetic field at the top of the helmet to the interplanetary space, becoming one of the sources of the southward component of the interplanetary magnetic field. The magnetic field within 3.5 solar radii (R⊙) The helmet section will appear fine structure, forming two high speed belts along the outer boundary of the helmet, and horseshoe density (bright) ring structure. These results show that there is an important dynamic interaction between the high-speed plasma near the sun and the helmet, which has an important influence on the three-dimensional structure of the solar wind in the interplanetary space.
