【 摘 要 】

Expressions for the dependencies of the specific surface energy σ and its isochoric derivative with respect to the temperature (∂σ/∂T)V versus of the relative volume V/V0 of the simple matter crystal are received. It is shown that isotherm σ(V/V0) has a maximum at (V/V0)max<1, it decreases at compression or spraining, and it is passing at the definite value (V/V0)frS< (V/V0)max<1 and (V/V0)frL>1 to negative region: σ(V/V0) fr=0. It must cause the fragmentation of the crystal at V/V0<( V/V0)frS or V/V0>( V/V0)frL.
