据中新网兰州5月17日电，记者17日从中国科学院兰州化学物理研究所（以下简称“兰州化物所”）获悉，我国液体润滑材料在太空中完成了首次舱外暴露实验。71件舱外暴露实验装置及科学实验样品已移交至该所，研究人员正对其展开深入研究。
据了解，这次实验的液体润滑材料及装置已经在轨实验满一年，其暴露舱外的过程标志着我国在太空材料科学领域的一次重要突破。这批材料主要包括18台套动态摩擦学装置和134项科学实验样品。
此次实验的成功，不仅验证了我国液体润滑材料在极端太空环境下的稳定性和可靠性，还为我国空间站的长期运行提供了重要的技术支持。舱外暴露实验是为了研究太空环境下材料的性能变化，这对于我国未来空间站长期运行和宇航员的生活保障具有重要意义。
兰州化物所表示，接下来将对这些实验数据和样品进行详细分析，以期在液体润滑领域取得更多科学突破，进一步推动我国空间科技的发展。
这次太空舱外暴露实验的成功，展示了中国在空间科技领域的强大实力和国际领先地位，也为我国液体润滑材料的研究和应用开辟了新的天地。未来，我国将继续加大在空间科技领域的投入，为人类的太空探索做出更大的贡献。

#### Liquid Lubricant Extravehicular Exposure Experiment Successfully Completed in China
According to a report from the Lanzhou Institute of Chemical Physics (hereinafter referred to as “Lanzhou IP”) of the Chinese Academy of Sciences on May 17th, via the China News Service, the country’s liquid lubricant has completed its first extravehicular exposure experiment in space. Seventy-one extravehicular exposure experiment devices and scientific experiment samples have been handed over to the institute, and researchers are now conducting in-depth studies on them.
It is understood that the liquid lubricant and its devices from this experiment have been in orbit for a full year, and the process of exposing them to the outside of the module marks an important breakthrough for China in the field of space materials science. The batch of materials mainly includes 18 sets of dynamic tribology devices and 134 scientific experiment samples.
The success of this experiment not only verifies the stability and reliability of China’s liquid lubricants in extreme space conditions but also provides significant technical support for the long-term operation of China’s space station. Extravehicular exposure experiments are conducted to study the performance changes of materials in space environments, which is of great importance for the long-term operation of China’s future space station and the life support of astronauts.
Lanzhou IP stated that they will conduct a detailed analysis of these experimental data and samples in order to achieve more scientific breakthroughs in the field of liquid lubricants and further promote the development of China’s space technology.
The success of this extravehicular exposure experiment demonstrates China’s strong capabilities in the field of space technology and its leading international position, and it also opens up new horizons for the research and application of China’s liquid lubricant materials. In the future, China will continue to increase its investment in the field of space technology to make greater contributions to human space exploration.
