研究了回旋相位聚束离子对近垂直超临界激波前沿离子压力张量结构的影响。反射离子的存在导致压力张量的显著非对角元素的出现。在离子镜面反射模型内分析了足部压力张量的行为。压力张量的非对角元素直接与冲击波阵面中的电势电场相关，并且可以对交叉冲击电势做出实质性贡献。
We study the influence of the gyrophase-bunched ions on the tensorial structure of the ion pressure in the front of a nearly-perpendicular supercritical shock. Presence of reflected ions results in the appearance of significant off-diagonal elements of the pressure tensor. Behavior of the pressure tensor in the foot is analyzed within the model of the specular reflection of ions. The off-diagonal elements of the pressure tensor are directly related to the potential electric field in the shock front and can substantially contribute to the cross-shock potential.
