We attempted to take a complex approach to estimation 
of the energy introduced by microparticles into a metallic obstacle 
and the energy expended for their superdeep penetration realized in 
the case where they penetrate into the obstacle to a depth of tens 
or hundreds of millimeters. The disbalance (two- to ninefold) arising 
in this case between the expended and the introduced energy was explained 
by the appearance of an additional energy source under the conditions 
of dynamic compression of microcavities in the process of superdeep 
penetration.
