中文摘要本文研究了强磁场结构在18—240R_s的行星际空间的膨胀效应。模拟结果表明,强磁场结构的膨胀能够形成典型的磁云剖面结构;膨胀速度明显依赖于磁场强度的大小;强磁场结构运动的速度直接影响到它的动力学特性。
英文摘要This paper studies the expansion effects of strong magnetic field structure (SMFS) in interplanetary space (from 18 R8 to 240 R8). Simulation results show that the main body of SMFS is typically with a strong magnetic field, low β, high μp, μk, low temperature and low density, but high temperature and density existing in the front and rear of the structure; expansion of SMFS results in the saw-tooth profile of radial velocity; expansion velocity of SMFS obviously depends on the strength of magnetic field;there is almost no relation between propagati,rn velocity of the structure center and the strength of magnetic field when SMFS is motionless relative to the inner boundary; the s ructure can intensify (weaken) the compression to the plasma in The front (rear) of the structure when SMFS moves relating to the inner ho undary. The expansion of SMFS can generate a typical profile of magnetic cloud.
