| 摘 要： | 黑腔材料的大气寿命是点火黑腔的重要指标之一，寿命实验是黑腔研制中的必要环节。本文通过X射线光电子能谱方法分析了DU/Au平面膜储存于大气环境中O含量及其分布随时间的变化规律，利用X射线衍射仪测试了相同情况下薄膜的结晶状态。实验证明，这种平面膜大气寿命（O原子百分数低于5%）在18～21 d之间，此期间内薄膜晶体结构无明显变化，未检测到氧化物结晶信号。

| Abstract: | The period of validity of hohlraum in atmosphere is an important parameter, and the measurement for it is a crucial step in the R&D of hohlraum. By the surface analysis, the evolvement of O in the DU/Au foils in atmosphere was researched, and the crystal state of this foil was analyzed through XRD. It’s proved that the period of validity of this foil (O atomic percentage <5%) is between 18 d and 21 d, the crystal oxide isn’t discovered, and the crystal state of this foil doesn’t obviously change. |
