研究了在氢原子流存在的情况下日光层顶停滞点附近的等离子体流。日球层顶两侧的等离子体被认为是单一流体。忽略等离子体流对H原子流的逆反应，取H原子流的密度、温度和速度恒定。描述等离子体流的解以相对于距对称轴的径向距离的幂级数展开的形式获得。根据所得解得出的主要结论是日球层顶不再是不连续面。相反，它是将太阳风和星际介质流分开的表面，所有等离子体参数在该表面上都是连续的。
The plasma flow in the vicinity of the heliopause stagnation point in the presence of the H atom flow is studied. The plasma at both sides of the heliopause is considered to be a single fluid. The back reaction of the plasma flow on the H atom flow is neglected, and the density, temperature and velocity of the H atom flow are taken to be constant. The solution describing the plasma flow is obtained in the form of power series expansions with respect to the radial distance from the symmetry axis. The main conclusion made on the basis of the obtained solution is that the heliopause is not the surface of discontinuity anymore. Rather, it is the surface separating the flows of the solar wind and interstellar medium with all plasma parameters continuous at this surface.
