摘　　要：用解析方法和数值模拟方法研究了用冲击波测量黑腔辐射温度的可能性及其可能达到的精度。结果表明，通过精确测量镶嵌于黑腔靶侧面中间的Ａｌ楔形靶中冲击波的传播速度和压力的变化来推断黑腔的辐射温度随时间的变化是一种可行的方法，而且可以大幅度地提高辐射温度的测量精度。The possibility of measuring radiative temperature inside the hohlraum by shock wave method and the possible measuring precision have been studied using analysis and numerical simulation. The results show it is reliable method that the radiative temperature inside the hohlraum is deduced by accurately measuring the variations of speed and pressure of shock wave in the Al cuniform target, and whick can also greatly improve measuring precision.
