摘要：
The structure of the averaged plasma pressure distribution in the plasma ring around the Earth at geocentric distances of similar to 6-10R(E) has been determined. The distribution function moments measured on the international THEMIS mission satellites have been used. The plasma pressure distribution in the equatorial plane at 15R(E) > X-SM > -15R(E) and 15R(E) > Y-SM > -15R(E) has been statistically studied. The radial dependence of the plasma pressure at the day-night and morning-evening meridians has been analyzed. It has been indicated that the plasma ring around the Earth has a structure, which is close to being azimuthally symmetric. The achieved results have been compared with the pressure distributions obtained previously. It has been indicated that in the overlapping regions, the achieved results agree with the previously obtained data within the pressure determination errors.
