New Approach to the Construction of the Equation of State of Matter with a Phase Transition at the Shock-Wave Front. Equation of State of Phenylone

摘要

The parameters of the second phase state of phenylone are refined based on a set of independent measurements of three physical parameters simultaneously in shock-wave experiments (full experiment). It is experimentally confirmed that the reflection method of determining Hugo-niots gives correct results only for the cases where the phase state of the material at the shock-wave front remains unchanged. This technique must be supplemented by direct pressure measurements in the test material with a phase transition and methods of determining the start point of the Hugoniot of the second adiabatic phase state (P_(e)sw, U_(e)sw).
