【Abstract】

<正>The phenomenon of super deep penetration of solid micro-particles into a solid target under shock has not been interpreted convincingly until now.The conception of highly excited states,developed by the academician V.E.Panin and others,opens a new way to interpretation of this phenomenon.According to this conception,under condition of highly excited state,the number of allowable structure states in crystals exceeds significantly the number of atoms,i.e.in crystals new degrees of freedom arise.Highly excited crystals become in essence a superposition of several structures Therefore,in highly excited states,the material of target may be looked at as a system of weakly interacting particles.The application of the theory of a system of weakly interacting particles shows that,when the velocity of penetrating particles exceeds the velocity of thermal motion of particles of the target material,the decrease of the coefficient of friction is inversely proportional to the relative velocity of penetrating particles to the cube power.In this way the effect of losing of friction in penetration of solid particles into solid targets is interpreted.But the problem of the structural level of the phenomenon is still open.
