#### abstract

It is shown that quantum
mechanics can be presented as a hydrodynamic of some quantum fluid. In this
case the quantum mechanics ceases to be an axiomatic conception, because the
axiomatic object of QM (wave function) ceases to be an axiomatic object. In the
hydrodynamics the wave function is a method of an ideal fluid description. The
quantum mechanics becomes to be a classical dynamics of the stochastic
particles. Problems of the quantum mechanics interpretation disappear, because
the interpretation is determined by the mathematical formalism of classical
dynamics.
