摘要
The results of experiments on simultaneous registration of optical emission intensity and electrical resistivity of hydrogen layer at a multiple shock compression to pressure 106, 123 and 150 GPa are presented. The experimentally determined thermodynamic parameters of hydrogen at the first step of compression are consistent with results of a semi-empirical equation of state for molecular hydrogen. Hydrogen electrical conductivity was traced from 0.1 to 1000 1/(Omega cm) under various regimes of compression and subsequent expansion. (C) 1999 Elsevier Science B.V. All rights reserved.
