Core Viewpoint - A significant cold wave is affecting a large part of China, bringing extreme low temperatures, rain, snow, and ice, with the China Meteorological Administration issuing multiple weather warnings and emergency responses [1][2]. Group 1: Weather Impact - The cold wave has led to a drastic drop in temperatures, particularly in southern regions, with some areas experiencing freezing rain [1]. - The cold air mass from Siberia is responsible for this cold wave, which is characterized by a broad impact area, prolonged duration, and significant temperature drops [1][2]. - The central and eastern parts of China will experience extensive rain and snow, with specific regions like Hubei, Anhui, Jiangxi, Hunan, and Guizhou facing freezing rain lasting 2 to 3 days, accumulating between 5 to 10 millimeters [2]. Group 2: Mechanism of Freezing Rain - The formation of freezing rain is linked to a temperature inversion where warm air exists above cold air, causing ice crystals to melt into supercooled water droplets that freeze upon contact with surfaces [2]. - Many affected areas have low cloud layers, resulting in freezing rain primarily from supercooled droplets rather than ice crystals [2]. Group 3: Risks and Precautions - The combination of low temperatures and freezing rain poses risks such as road icing, damage to electrical and communication infrastructure, and agricultural harm [3]. - Public safety measures are advised, including precautions against slipping and freezing, as well as ensuring proper warmth during outdoor activities [3].

为验证新材料的长期稳定性，团队构建了自动化测试系统，在40天内对材料连续实施1000次"破坏—修 复"循环。每次实验均人为制造50毫米长的分层裂纹，随后触发加热自愈机制，并检测修复后的承载能 力。结果显示，这一材料在经历千次循环后仍保持优异性能，抗断裂能力显著优于传统复合材料，且韧 性衰减极为缓慢，创下自愈次数新纪录。 目前，广泛使用的纤维增强聚合物（FRP）复合材料，因其轻质高强特性，被广泛应用于飞机、汽车、 风力发电机和航天器中。但这类材料长期面临"层间分层"难题，即内部裂纹导致纤维层与树脂基体分 离，严重影响结构完整性。自20世纪30年代以来，这一问题始终制约着复合材料的耐久性，传统FRP设 计寿命通常仅为15年至40年。 团队表示，在实际应用中，材料仅在遭遇冰雹、鸟撞等突发损伤或定期维护时才启动修复程序。据此推 算，此类部件理论上可持续使用达125年以上，甚至在500年内仅需修复4次即可维持功能稳定。这项技 术将大幅降低工业设备的维修成本与能源消耗，减少废弃部件带来的环境污染，对难以返修的航天器具 有革命性意义。 美国北卡罗来纳州立大学科学家研发出一种新型自愈复合材料，可实现上千次自我修复，预计能使飞 ...
