  The results of the analysis of the deviation of the force equilibrium for
ions from the neoclassical theory prediction, calculated using the direct
measurements of the radial electric field, in the view of its possible local
and nonlocal correlation with the profiles of electron, Te, and ion, Ti,
temperatures in the T-10 tokamak are presented. Local correlations are analyzed
by means of the Pearson's correlation. Nonlocal correlations are treated with
an inverse problem under the assumption of an integral equation relationship
between the deviation and Te and Ti profiles. The discharges with zero, weak
and strong auxiliary heating (electron cyclotron resonance heating) are
analyzed. It is found that the electrons substantially (not less than ions)
contribute to the deviation of the ion equilibrium from the neoclassical theory
prediction both in the local and nonlocal models.
