Query: Nonminimal Macroscopic Models of a Scalar Field Based on Microscopic
  Dynamics. II. Transport Equations   The article proposes generalizations of the macroscopic model of plasma of
scalar charged particles to the cases of inter-particle interaction with
multiple scalar fields and negative effective masses of these particles. The
model is based on the microscopic dynamics of a particle at presence of scalar
fields. The theory is managed to be generalized naturally having strictly
reviewed a series of its key positions depending on a sign of particle masses.
Thereby, it is possible to remove the artificial restriction contradicting the
more fundamental principle of action functional additivity. Additionally, as a
condition of internal consistency of the theory, particle effective mass
function is found.
