摘要：

Absolute-intensity measurements of luminous emissions from shocked silicon show significant disagreement with predictions that assume thermal equilibrium between electrons and ions is reached immediately behind the shock front. Taking into account both electron-ion equilibration and electron thermal conduction, we have estimated an electron-ion coupling coefficient of 10(16) W/m3K. This finding will also have important ramifications in pyrometric determinations of shock temperatures.
