冲击波在变密度、运动介质中的传播

本文得到了点源爆炸波在变密度、运动介质中传播的分析解(ω=2,γ=5/3),讨论了耀斑引起的击波在太阳风中传播的一些特性。发现1AU附近区域恰是击波各种重要效应的过渡区;击波减速等效指数i(D=K(u_o,E_s)R-i(u_o,E_s,R))是介质运动速度u_o.击波能量E_s,和击波传播距离R的函数,通常是小于1/2的,不是自型理论预言的那样简单;太阳风的对流效应使击波可以传播到10-20AU以远,与飞船(先躯者10、11号)新近的观测相吻合。 

THE BLAST WAVE PROPAGATING IN A MOVING MEDIUM WITH VARIABLE DENSITY

The blast wave propagating from a point source in a moving medium with variable density has been treated.On the basis of the analytical solutions obtained by the paper some important characteristics of the flare-generated shock waves propagating in the Solar wind are discussed.It is found that the 1AUregion is just a transitional region of various important effects of the flare-generated shock waves; the equivalent power of the deceleration of Shock wave (D=K(u_o,E_s)R-t(u_o,E_s,R) is the function of Selar wind velocity u_o,Shock wave energy E_s and Shock's propagation distance R,usually i<1/2 and the convection effect of Solar wind is very important when R>1AU,due to this effect a stronger Shock wave could propagate to the 10-20 AU beyond,it consists with the recent observations of the space-crafts Pioneer 10 and 11.
