Abstract
The thermal emission from a water layer shock-compressed by an incident wave and a wave reflected from a LiF window was recorded in the range of incident-wave intensity of 28-36 GPa. Losses of the luminous flux at the boundaries were estimated. The temperature of water compressed by one and two shock waves were calculated, and the calculation results are in good agreement with experimental data.
