北京科学家研制成比纸还薄的“铁纸”,表明我国在纳米材料技术领域实现重大突破。把沸腾的铁水以每秒钟100万摄氏度的速度快速冷却,会发生什么奇迹?近日在北京市重大科技项目“非晶、纳米晶制品研究及产业化”验收会上,见到了这种神奇的东西:一片薄得像玻璃纸一样的“铁片”和
The “iron paper” that Beijing scientists developed even thinner than paper shows that our country has made major breakthroughs in the field of nanomaterials technology. What will happen to the rapid cooling of boiling hot metal at the rate of 1 million degrees centigrade per second? Recently, I was able to see such a magical experience at the acceptance test of the major science and technology project of Beijing Municipality on the research and industrialization of amorphous and nanocrystalline products Something: a piece of thin iron-like “iron piece” and
