The reemission delay times of Au disk vs X rays photon energy were given and compared with recent experimental results.

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。

The gas concentration can be obtained by measuring the laser build-up time, which is closely related with the cavity loss an.

激光激射延迟时间与激光器谐振腔损耗密切相关,气体浓度的改变将引起谐振腔损耗的改变,通过测量激光激射延迟时间可以获得气体的浓度。

The principle of intracavity laser absorption and the relationship between gas concentration and the laser build-up time is outlined.
