Abstract Results of experimental studies of the electron concentration and near-solar plasma velocity dependences on the heliocentric distance obtained in 1970–2012 by the method of radio transillumination by signals of spacecraft for the region of 3–50 solar radii are presented. A comparative analysis of different approximations of these dependences is given and it is shown that joint analysis of the data on the plasma velocity and concentration with allowance for independence of the plasma integral flux on the heliocentric distance makes it possible to find analytical expressions corresponding well to experimental data. Analytical approximations and graphs of dependences of the velocity, concentration, acceleration, force, and kinetic energy on the distance in the regions of solar wind acceleration for low and moderate solar activity are presented.
