中国几乎与世界同时起步研究和发展纳米技术 ,并在短短的十几年内取得了一系列的成就。１９９１年碳纳米管被发现 ,它的强度比钢大１０倍、质量却只有相同体积钢的１／６。北京大学的科学家们与世界同期制备出当时世界上最长的碳纳米管。１９９３年 ,中国科学院北京真空物理实? Almost simultaneously with the rest of the world, China has started research and development of nanotechnology and has achieved a series of achievements in just a dozen or so years. Carbon nanotubes were found in 1991, its strength ten times larger than steel, the quality is only the same volume of steel 1/6. Peking University scientists at the same time with the world prepared the world’s longest carbon nanotubes. In 1993, Chinese Academy of Sciences Beijing vacuum physical reality?
