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.

本研究项目对空间环境模拟的实验条件进行了详细的分析，为利用第三代量子同步辐射建立高质量和定量的地面模拟奠定了基础。得到了以下结论：1.模拟实验中原子的碰撞能影响材料的腐蚀；2.含氟材料不存在紫外线的协同作用；3.原子氧以外的中性气体的影响不容忽视；4.原子氧的碰撞能影响DLC放氢；5.原子氧暴露在掺硅或掺钛的DLC表面形成了保护性的氧化层。这些实验结果和结论是通过使用同步辐射和高能离子加速器进行精密表面分析而得到的。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。
