| Abstract: | The formula about the caloric capacity with the iso - strain of the solid is derived anddefined. On this basis, the differential formulas of the internal energy and the entropy with theelastic solid system are set up. The puremetals being taken as an example, the internal energy andthe entropy under the condition with the variable coefficient of the thermal - expansion areanalysed. |
