对受冲击的硅发光的绝对强度测量表明，与假设电子和离子之间的热平衡就在激波前沿后面达到的预测有很大不同。综合考虑电子-离子平衡和电子热传导，我们估算出电子-离子耦合系数为10(16)W/m~3K。这一发现还将对冲击温度的高温测定产生重要的影响。
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.
