在“神光Ⅱ”三倍频装置上,由黑腔产生的辐射驱动铝台阶样品产生冲击波,采用光学条纹相机测量冲击波速度,利用冲击波速度与黑腔辐射温度的定标关系,获得了与软X光能谱仪测量相一致的辐射温度;采用热波关系和能量守恒原理对辐射温度进行了分析,计算结果与实验结果一致。
In “ShenGuang Ⅱ” triple frequency multiplier device, the radiation generated by the black cavity drives the aluminum step sample to produce the shock wave. The optical streak camera is used to measure the shock wave velocity. Based on the scaling relationship between the shock wave velocity and the black cavity radiation temperature, X-ray spectrometer to measure the same radiation temperature. The radiation temperature was analyzed by the theory of heat wave and the principle of energy conservation. The calculated results are consistent with the experimental results.
