Abstract Temperature dependences of self‐diffusion coefficients, scattered electron intensities, lattice parameters and atomic bond energies are considered. All curves representing the dependences are “splitted” into two linear ones: for a surface and for a volume of the crystal. This splitting can be eliminated and the lines representing the two linear dependences be matched, if a new variable T c = nT (where n is a scale factor and T e is an effective temperature) is introduced. The value of n is shown to vary over not a wide range (from 1.6 to 8) for all the processes considered and in all cases n > 1. A possible physical sense of the effective temperature has been considered.
