  In conventional quantum mechanics the quantum particle is a special object,
whose properties are described by special concepts and quantum principles. The
quantization is a special procedure, which is accompanied by introduction of
special concepts, and this procedure cannot be repeated. In the model
conception of quantum phenomena (MCQP) the quantum particle is a partial case
of a stochastic particle, and the quantum dynamics is a special case of the
stochastic particle dynamics. In MCQP the quantization is a dynamical
procedure, where a special quantum term is added to the Lagrangian of the
statistical ensemble of (classical) particles. This procedure can be repeated
many times, because it is not accompanied by introduction of new concepts. It
is very convenient from the formal viewpoint, because the set of dynamic
quantizations forms a one-parameter group, which allows one to separate the
dynamical and statistical (stochastic) properties.
