早上看到参考消息上的这篇文章，没想到中国的纳米技术进步得这么快。没准过不了多久，纳米产品就成为我们生活的主流了。

        在中国最先进的科学实验室里，两名博士生穿着白色防护服，专注地听玛利亚.凯莉的流行经典《hero》。吸引他们注意力的不是这首歌，而是发出这种声音的几毫米厚的透明条----他们希望这种纳米扬声器能根本改变我们在哪里听音乐以及如何听音乐。

        北京清华大学纳米技术实验室主任范守善说：“这非常先进。”这个看起来只不过薄薄一条透明塑料的扬声器没有磁铁、扩音器或锥形部件，可以用来把几乎任何表面转换成音乐厅。它由碳纳米管薄膜制成，加热后使周围空气振动，发出声音。范守善说：“这个扬声器柔韧灵活。你可以把它贴在汽车后窗上，在那儿放音乐。”

中、美、欧齐头并进

         哈珀（CMP公司总裁）预计，到2010年，纳米技术和生物这两个领域将完成合并，开始生产大批新型药物和临床设备。哈珀的调查认为，到2012年，军事用途的纳米技术产品将占该市场总额的14%。汽车产业的纳米技术产品将占4%的市场份额，而纳米食品可能占2%。到2012年，为解决水、空气和土壤污染而设计的纳米技术产品也将形成巨大市场。哈珀说：“在环保材料领域，中国在某些方面的思路甚至走在美国前面。他们已经在形成一套关于应当如何利用这些技术改善环境的制度。”美国可能在纳米技术的总体上领先，但哈珀认为，到2012年，中国可能与欧盟和美国齐头并进。

        加州大学的理查德.阿佩尔鲍姆预计，到2014年，全球纳米技术市场总额将达到2.6万亿美元，占当年制造业的15%。他说，中国、美国、英国和日本等40多个国家正在投资于被视为“全球经济竞争力关键”的纳米技术。

        阿佩尔鲍姆还说，如果其中任何一个国家能成功地在这个市场抢得巨大份额，那么“该国将足以成为全球经济领袖”。

China's giant step into nanotech

Seated inside one of China's most advanced science laboratories, two PhD students dressed from head to toe in protective white suits listen intently to Mariah Carey's pop classic Hero. It is not the song, but the millimetre-thin, transparent strip making the sound that captures their attention - a nano-speaker they hope will revolutionise where, and how, we listen to music.

"This is cutting edge," says Professor Shoushan Fan, director of the nanotechnology lab at Beijing's prestigious Tsinghua University. Without a cone, magnet or amplifier, the speaker, which looks little more than a slim film of see-through plastic, can be used to transform almost any surface into an auditorium. It is made from nanocarbon tubes which, when heated, make the air around them vibrate, producing the sound. "The speaker's bendy and flexible," says Fan. "You could stick it to the back window of your car and play music from there."

Harper predicts that by 2010, areas of nanotechnology and biology will have merged, setting in motion the production of a wealth of new drugs and clinical equipment (such as the vials of nanomaterials for use in health products, clothes and cosmetics). His research sees nanotech pharmaceutical and healthcare products worth an estimated $3.2tn by 2012, with military-use nanotech products taking 14% of the total market and worth $40bn.

Nanotech products for the motor industry will make up a 4% chunk of the market, while nano-foods are likely to corner up to 2%. Nanotech products designed to tackle water, air and soil pollution will also be big business in 2012. "In terms of environmentally beneficial materials, in some ways the Chinese are further along in their thinking than even the US," says Harper. "They are already putting together a system to work out how we can use these technologies for the good of the environment." The US may still lead the nano surge overall, but Harper believes China will be on a par with the EU and US by 2012.

Richard Appelbaum, from the Center for Nanotechnology in Society at the University of California, puts the global nanotech market figure at $2.6tn by 2014, or 15% of manufacturing output in that year. China, along with 40 other countries including the US, UK and Japan, is investing in nanotechnology "as a major key to global economic competitiveness", he says.

If any one nation succeeds in cornering the giant's share of the market, it "would be sufficient to confer global economic leadership on the country", he adds.
