一 | 　　中新社北京8月25日电 (记者刘亮)中国国家市场监管总局25日公布，由中国专家牵头制定的国际标准《电子和通信设备用变压器、电感器的测量方法和试验程序》，由国际电工委员会(IEC)与电气电子工程师学会(IEEE)近日联合发布，正式成为全球电子通信磁性元件检测领域统一技术规范。

二 | Teens in the city of Prayagraj in India's Uttar Pradesh are making headlines for manufacturing crude bombs from easily available explosive materials for just INR 60 to 80 ($1.01), and hurling them at educational institutions and shops.,As many as 35 students, including 27 minors, have recently been arrested in Prayagraj after learning how to make bombs by watching viral videos on social media and putting their newly-acquired skills to practice. The adult students have been sent to jail, according to the police.,Shocked by the details that emerged during the interrogation of the students, Shailesh Kumar Pandey, Superintendent of Police in Prayagraj city, told Indian news agency IANS that the minors between 14 and 17 years of age have become experts in making a low-intensity crude bomb within minutes.,"They would take electrical tape from their houses, and purchase two low or high-intensity firecrackers from the market. Then they collect its explosive material on a piece of paper, add pieces of glass bottle and stones, and wrap it with electrical tapes," Pandey added.,During the interrogation, the cyber unit of the Prayagraj District Police found that students would coordinate the production of bombs through social media groups and share videos on how to make them at home via these groups.,Several such groups are now under scrutiny, with the authorities asking the parents of the adult students sent to jail to talk to their children.,At least 10 such groups, as well as student profiles on social media, are now being monitored by police.。　　国家市场监管总局介绍，该标准的发布标志着中国在该领域正式跻身全球标准引领行列，为5G通信、算力基建、新能源汽车等新一代信息技术与新能源产业高质量发展，筑牢了底层标准根基。　　据介绍，该标准精准适配5G和AI(人工智能)服务器电源、新能源功率变换等前沿产业发展需求，统一规定动态电容、热电偶温升、增量电感、差分电感、能量电感、振幅电感测量等关键测试方法，以及高频工况损耗、交流电阻等十余项试验流程，为全球磁性元件的研发设计、性能检测、质量评定提供了统一、权威的国际技术标尺。
