摘要

摘要: 考虑窗口不透明性、界面发射率和热传导等因素对冲击温度测量中辐射度的影响，认为在冲击压缩下窗口不透明性的增大是导致辐射度随时间变化的重要因素。用流体动力学方程、辐射输运方程并计及热传导数值模拟了辐射度，得到了与实验一致的结果。

Abstract: Considering the effects of the window opacity, the interface emissivity and the heat conduction on the radiance in shock temperature measurements, we present that the increase of opacity under shock compression is an important factor that influences the time dependence of the radiance. Using the equation of hydrodynamics, the equation of radiation transport and the heat conduction, we numerically simulate the radiance, which agrees with the experimental result.
