本研究项目详细分析了利用3^<rd>代量子同步辐射建立高定性和定量地面模拟的空间环境模拟实验条件。我们得到了以下结论：1。模拟实验中原子碰撞能量对材料侵蚀的影响2. 氟化材料不出现与紫外线的协同效应；3. 除氧原子外的中性气体的作用不容忽视；4. DLC中氢的释放受原子氧碰撞能量的影响；和5。通过原子氧暴露在Si或ti掺杂的DLC上形成保护氧化层。这些实验结果和结论是利用同步辐射和高能离子加速器进行精密表面分析得到的。通过本课题的研究，发现了可靠的空间环境模拟的许多重要关键点。

This research project reveals the detail analysis of experimental conditions in space environmental simulation for establishing the highly qualitative and quantitative ground-based simulation by using the 3^<rd> generation quantum synchrotron radiation. We have obtained the following conclusions: 1. Collision energy of atoms influences the erosion of materials in simulation experiments; 2. Synergistic effect with ultraviolet does not appear on fluorinated materials; 3. Effect of neutral gases beside atomic oxygen cannot be neglected; 4. Release of hydrogen from DLC is affect by the collision energy of atomic oxygen; and 5. Protective oxide layer is formed at the Si- or Ti-doped DLC by atomic oxygen exposure. These experimental results and conclusions are obtained by the precise surface analysis with the use of synchrotron radiation and high-energy ion accelerators. Many important key points for the reliable space environmental simulation are discovered through this research project.
