11月13日，第十三届国际宇宙日（ICD）活动圆满落幕。来自全球13个国家的60余所中学、大学及研究机构的青年科研团队齐聚线上，围绕天体粒子物理学展开深度探索与交流。湖南师大附中金宏宇、唐博、周子皓、彭思然四名学子在马顺存老师的指导下，在国际舞台崭露头角，其研究成果获得与会专家与同行的高度评价。
国际宇宙日活动是全球青年学子参与天体粒子物理研究的重要平台，旨在通过实践探索宇宙射线等前沿科学领域。今年活动中，各国参与者通过实验观测、数据分析与科学推理，近距离体验科研全过程。湖南师大附中团队于10月底启动备赛，经过10多天系统学习，快速掌握宇宙射线基本原理与科学研究方法，确定以“宇宙射线强度与大气压强的关系”为研究主题。团队成员分工协作，结合文献调研与数据分析，最终形成完整研究论文。
11月13日晚的国际交流环节中，湖南师大附中学子通过视频会议向全球团队汇报研究成果，详细阐述了实验数据处理及结论推导过程，并与来自中国、美国、德国、意大利、不丹、立陶宛、希腊、格鲁吉亚、肯尼亚、法国、阿拉伯联合酋长国、土耳其、伊朗等国的青年研究者展开热烈交流，针对宇宙线相关问题交换见解。
此次活动中，中国共有包括大湾区大学、北京市东直门中学、江苏省姜堰中学、石家庄市第一中学、江苏省兴化中学、清澜山学校、朝阳垂杨柳中学等在内的多所单位及中学参与交流活动。湖南师大附中学子不仅通过项目研究深化了对现代科学前沿的认知，更在团队协作中收获跨国友谊，锤炼了科学探究能力。
湖南师大附中表示，学校将持续推进国际化科研育人实践，鼓励学生立足全球视野探索未知，为培养新时代创新型人才搭建更广阔的平台。此次国际交流不仅是对学生科研能力的肯定，更是中国基础教育阶段科创教育成果的生动体现。
附：研究论文
Research
This study is based on data collected in March 2024 by a cosmic ray detector array installed at Beijing Dongzhimen Middle School (latitude 39.933°N, longitude 116.417°E, elevation 46.4 meters). The relationship between cosmic ray intensity and atmospheric pressure was analyzed using local atmospheric pressure observations. The array consists of nine plastic scintillator detectors arranged in a 3×3 matrix, with a spacing of 10 meters between detectors. Each detector has a sensitive area of 0.5 square meters. When charged particles, such as muons, pass through the scintillator, they excite fluorescence, which is then converted into electrical signals via photomultiplier tubes. Due to the strong penetrating ability of muons, the experiment was designed to record a valid cosmic ray event only when all detector units generated signals simultaneously within a specific time window, effectively excluding noise interference. Based on 31 consecutive days of observational data from March, we statistically analyzed the local atmospheric pressure and the daily muon count (Figure 1) and plotted the relationship between cosmic ray intensity and atmospheric pressure (Figure 2). The results show that as atmospheric pressure increases, cosmic ray intensity gradually decreases. This phenomenon can be explained by the atmospheric shielding effect: higher pressure corresponds to a greater equivalent atmospheric thickness, increasing the probability of cosmic rays being absorbed or scattered as they pass through the atmosphere. As a result, only higher-energy primary cosmic rays can reach the ground, leading to a reduction in detected cosmic ray intensity.

Experimental Paper on the Relationship Between Cosmic Ray Intensity and Atmospheric Pressure
The High School Attached to Hunan Normal University
Background Information
Cosmic rays refer to streams of high-energy subatomic particles originating from outer space, primarily composed of charged particles. Approximately 89% of these particles are protons, 10% are helium nuclei, and the remaining 1% consists of heavier atomic nuclei. When these high-energy particles enter Earth's atmosphere, they interact with atomic nuclei in the air, producing a large number of secondary particles and forming extensive air showers. A significant amount of secondary charged particles generated during the shower process reach the ground almost simultaneously. By detecting these "shower events," scientists can indirectly study the properties of the primary cosmic rays. Generally, the higher the energy of the cosmic rays, the larger the spatial distribution range of the shower they trigger.The High School Attached to Hunan Normal University
