Is
established, that the basic reason both deformation, and reduction of speed of
radial compression, is the forward moving of cavities caused by influence of a
gradient of pressure in non-uniform hydro-dynamical, hydroacoustic or
hydrostatic fields. The special method of the mobile potentials allowing to
execute on a long interval time the analysis of transformation spherical babble
in a deformed cavity is developed and also to calculate the characteristics of
movement cumulative of stream for various phases of compression and expansion
of a cavity. The interaction of radial and forward movement deformed bubbles
and formation cumulative hydraulic of stream on a direction of a gradient is
investigated. The account of dynamics deformed of bubbles near to surfaces of
the unit is executed or at their arrangement close from each other. The
distinction of dynamics cumulative of stream is established at expansion and
compression of bubbles. The influence of the next cavities on processes them
coagulation, union or splitting is established.
