(Photo by Qian Boyu/Xinhua)Chinese archaeologists have pieced together ancient oracle bone fragments to decipher what they say is the earliest written record of a meteor shower, dating back more than 3,000 years and shedding light on astronomical observation in the Shang Dynasty (c.1600BC-1046BC), roughly the Late Bronze Age in the West in which Homer's Odyssey was rooted.
The inscription, found among more than 80,000 fragments, consists of three characters that read "star", "all" and "west," describing a large number of meteors streaking across the night sky and falling westward like rain, Huang Tianshu, a professor at Tsinghua University's Research and Conservation Center for Unearthed Texts, told the Global Times.
"The first character is 'star'… the second means 'all' or 'in batches', depicting meteors falling in large numbers like rain, and the third is 'west,' used as a verb to mean falling westward after crossing the sky," Huang said. "This is important astronomical data recording a meteor shower more than 3,000 years ago."
The team spent years rejoining shattered oracle bones, a process of piecing fragments back together, and only after reassembly did the meaning become clear. 
"Before rejoining, you have no idea what it is saying. Once rejoined, the content becomes largely intact and turns into a very important piece of material for studying history or language," Huang added.

The discovery is part of a decade long effort that has newly rejoined more than 1,200 groups of fragments, with the results published in a major compendium of oracle bone facsimiles. The research was part of a state-backed project on inheritance and studies of ancient Chinese scripts and civilization, CCTV reported.
The first phase of the national project is about to complete, yielding a string of major findings. These findings provide vital new materials for studying early Chinese civilization and demonstrate the significant value of ancient Chinese characters in the development of Chinese and even human civilizations, per CCTV.
。    中新网上海8月20日电 (杨海燕 李秋莹 何宝新)近日，2026年第13号台风“白海豚”影响上海。中船七〇四所利用这一窗口期，在长兴岛园区对新一代船用旋筒风帆进行了实景综合性能测试验证，取得成功。

B |          　　长兴岛地处长江入海口，是台风影响的重要区域。七〇四所成立现场指挥部，依据崇明气象台信息研判天气趋势，组织安全、技术和生产人员评估现场风险，校核载荷数据，加固结构部件，制定专项测试方案和应急预案，落实防护和应急保障措施。         　　测试期间，现场持续进行状态监测和数据采集，重点跟踪旋转体、支撑机构、智能控制系统及制动装置等关键部件。经过48小时连续数据收集，直径5米、高25.5米的旋筒风帆各系统运行稳定，设备响应正常，监测数据均在设计允许范围内，结构受力、抗风稳定性和控制性能达到预期目标，验证了其在复杂恶劣气象条件下的运行能力。         　　该旋筒风帆利用旋转筒体产生压力差，将自然风转化为船舶助推力，减少燃油消耗。根据航行条件，综合节能率可达5%~25%，全生命周期投资回收周期短于5年。该产品搭载了国内首个实测推力系统，通过监测船舶运动与受力，结合算法反推真实推力，填补了数据空白。

C | 目前已获得法国船级社(BV)和中国船级社(CCS)的认可证书。                        　　值得一提的是，七〇四所还提供了“风帆本体+防漂鳍+智能航行系统+全船能效管理”的整体解决方案。防漂鳍可补偿横向漂移，协同舵机提升航向稳定性并减少能耗；智能航行系统基于AI动态优化航线；能效管理模块协调风帆与主推进系统功率分配。         　　从实验室里的技术原理，到长江口风雨中的真实考验，从一面“借风而行”的旋筒风帆，到覆盖航行控制与能源管理的系统化解决方案，中船七〇四所正持续推动风能辅助推进技术走向工程化、实船化应用。         　　此次台风条件下的实景验证，为旋筒风帆工程化应用提供了关键数据支撑，也为其在绿色低碳航行中的实际使用积累了重要经验。(完) 【编辑:万纪玮】。
