利用二维辐射流体动力学程序LARED-H模拟了在SGIII原型装置上进行的黑腔物理实验，研究了激光强度对二维黑腔模拟的影响。模拟得到的辐射温度和X射线谱都与观测值吻合得很好，只是模拟得到的M带部分（大于2 keV）明显小于观测值。根据我们的研究，从激光到X射线的耦合效率约为70%的SGIII原型激光设施黑腔。
The Hohlraum physics experiments performed on the SGIII-prototype laser facility are simulated by using our two-dimensional radiation hydrodynamic code LARED-H, and the influence of laser intensity on the two-dimensional Hohlraum simulations is studied. Both the temporal radiation temperature and the x-ray spectrum from the simulations agree well with the observations, except that the simulated M-band fraction (greater than 2 keV) is obviously smaller than the observation. According to our study, the coupling efficiency from laser to x-ray is around 70% for SGIII-prototype laser facility Hohlraums.
