        <p>При взрыве мощных: зарядов ВВ в массиве образуются зоны испарения, плавления, дробления и трещинообразования. Предельное состояние породы при испарении и плавлении характеризуется через энтропию-характеристику, которая не зависит от условий опыта. Энтро­пия испарения, плавления являются константами пропорциональности в соотношениях между энергией испарения, плавления породы и температурой кипения, плавления ...</p>

        <p>At explosion of powerful: charges of explosives in a massif zones of evaporation, melting, crushing and cracking are formed.The limiting state of a rock at evaporation and melting is characterized through entropy-characteristic, which does not depend on conditions of experience. Entropy of vaporization, melting are constants of proportionality in the relations between the energy of vaporization, melting of the rock and the boiling, melting temperature ...</p>
