 激波法向和速度的确定 Alternative Title The Determinalion of the Normal Directions and of the Shosks Velocities 吕建永; 顾惠成; 北京8701信箱 Department 空间天气学国家重点实验室 Source Publication 吉首大学学报 1996 Volume 17Issue:2Pages:1-7 ISSN 1007-2985 Language 中文 Keyword 行星际 激波方向 法向磁场 法向和速度 Abstract 本文列举了各种计算行星际激波方向的方法,讨论了各种计算方法的适用范围.利用激波跳跃条件,得到激波法向磁场与激波两侧介质参量的关系.这样,从行星际激波的观测数据,可以求出激波的法向磁场,判断该激波是平行激波,垂直激波或斜激波.对不同类型的激波,挑选不同的计算方法,使它合适于不同类型的跃变关系特点,从而得到正确的计算结果.最后给出三个计算激波方向的例子. Other Abstract In this paper we have listed all kinds of methods of calculating the directions of the in-terplanetary shocks and discussed the applicable regions of those calculating methods using the leap conditions of the shocks we have also obtained the relationship between the normal magnetic field of the shocks and the parameters of the media beside the shocks ,so we can e-valuate the normal magnetic field of the shock and determine whether the shock is parallel or vertical or inclinde from the observation data of the interplanetary shocks，For the different types of shocks we have chose the different calculating methods to make them suit the char- acteristics of the different types of leap conditions. Thus we have got the correct calculating results. Finally we have given three examples of calculating the directions of the shocks.
