| 中文摘要: |
| 目的 分析“天舟一号”（TZ-1）货运飞船的空间污染探测器的在轨探测数据。方法 TZ-1货运飞船上的污染探测器采用石英晶体微量天平（QCM），利用污染物沉积在QCM探测器传感晶片表面引起的振荡频率变化情况来分析航天器在轨空间污染环境。根据其探测原理，通过分析下传的原始数据，得到航天器在轨的污染累积量结果。结果 航天器在轨飞行过程中，污染累积已达到会导致污染敏感器件光学性能明显退化的程度，并且污染源温度是影响航天器污染累积量的一个重要因素，可以将其作为航天器在轨污染控制的重要措施。结论 该研究结果可以为航天器污染设计、控制提供参考，为提高航天器可靠性设计提供数据支持。 |

| Objective To analyze on-orbit detection data of the space contamination detector for “TZ-1” Cargo Spaceship. Methods Quartz Crystal Microbalance (QCM) was used to detect contamination the TZ-1 to make use of the changes of oscillation frequency caused by contaminant deposited on the sensor crystal. The on-orbit contamination accumulation of the spacecraft was obtained by analyzing the downloaded original data based on the detecting principle. Results The detection data showed that optical properties of contamination sensitive components deteriorated significantly udder the influence of accumulation of contaminants. The contamination source temperature was an important influencing factor of contamination accumulation. Consequently, temperature could be taken as an important method for on-orbit contamination control on spacecraft. Conclusion These results can be references for contamination control design, and also provide data support for improving spacecrafts reliability. |
