The main hugoniots in the data base TEFIS of thermophysical properties of substances

TEFIS – is the data base for thermo-physical characteristics of matter in extreme conditions, which is developed in IMM RAS. It is based on experimental data and some original theoretical models. The significant part of this data base is devoted to shock waves. In that paper described a part of data base which allows building of main shock adiabatic curve in wide range of pressures. Moreover the precision for several substances is extremely high and in 5–10 times better then whole the world.
