  The elements of the theory of dynamical expansion of the theory of weak
interaction working at the tree level, i.e. the model of dynamical analogy of
Cabibbo-Kobayashi- Maskawa matrices, are given.
  The equation for mass difference of $K^0_1, K^0_2$ mesons or the length of
$K^0, \bar K^0$ meson oscillations in the phase volume approach in the frame
work of the standard model of the weak interactions and the model of dynamical
analogy of Cabibbo-Kobayashi-Maskawa matrices is calculated (in this model the
oscillations of $K^0, \bar K^0$ mesons arise at violation of strangeness by $B$
bosons). Comparison of the length of oscillations in the diagram and phase
volume approaches was done. The length of $K^0 \leftrightarrow \bar K^0$
oscillations in the phase volume approach is much more than the length of these
oscillations in the diagram approach.
