THE BLAST WAVE PROPAGATING IN A MOVING MEDIUM WITH VARIABLE DENSITY

Wei Feng-si(Institute of Space Physics, Academia Sinica)  
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 1AU region 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(u0,Es)R-t(u0,Es,R) is the function of Selar wind velocity u0,Shock wave energy Es and Shock's propagation distance R,usually i1/2 and the convection effect of Solar wind is very important when R1AU,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.
