摘要: 用一维多群辐射输运程序对X光加热金平面靶的物理过程进行了数值模拟, 计算出了X光再发射延迟时间, 与最近的双盘靶测得的再发射延迟时间的实验结果相当吻合。在各种因素的影响下, X光各能区再发射的延迟时间的变化趋势与实验结果一致的。这说明这个一维多辐射输运程序可以较好的模拟X光打击平面靶的实验结果。Abstract: One dimensional multi-group radiation transport program is used to simulate the process of X-rays heating Au disk. The reemission delay times of Au disk vs X rays photon energy were given and compared with recent experimental results. It is found that the theoretical results fitted well with the experimental results, especially the trend of reemission delay time. This proved that the one dimensional multigroup radiation transport program can do well in simulating the experimental process of X rays heating Au disk．
