The first chapter gives the summary of basic theories of EOS for solids, including often-used thermodynamic theories and phenomenological expressions during the study progress of EOS along with the finite strain theory. Furthermore, from the view of solid-state theory the general expression of EOS of solids P =Pc+Pn is given, and the microcosmic mechanism of compression for solids, i.e., the interactive potential energy between atomics, is also analyzed, subsequently several different forms of cold energies and pressures are derived.
