科学实验表明,当物质被分割到它的极限尺寸——十亿分之一米(纳米)的时候,就会出现一些鲜为人知的奇异现象:1克具有这种尺寸的微粒,它的表面积可高达几万平方米,由于表面积增大,活性就会增强,还很容易引起燃烧和爆炸;五颜六色的金属,当它被分割成纳米超微细粉末时,由于吸光能力增加而一律变成黑体,熔点也随之降低;在素以坚硬耐磨著称的结构陶瓷中,加入纳米粒子,会出现令人惊奇的超塑现象,延伸率可提高2倍。科学家们认为,这些奇异现象的产生,是来源于继物质的晶态、非晶态结构之后的一种新的物质结构形态——纳米态结构。这种新的物质结构形态,是一位长期从事晶体物理研究的德国科学家,在一次驱车于漫无边际的大沙漠旅行中构想出来的。空旷、寂寞的大自然环境,使他的思
Scientific experiments show that when the material is segmented to its limit size of one billionth of a nanometer (nm), some little-known strange phenomenon occurs: 1 gram of particles of this size whose surface area Can be as high as tens of thousands of square meters, due to increased surface area, the activity will be enhanced, but also very easy to cause burning and explosion; colorful metal, when it is divided into nanometer ultrafine powder, due to increased absorption capacity will become black body, The melting point will also be reduced; known to be hard and wear known in the structural ceramics, adding nanoparticles, there will be a surprising super-plastic phenomenon, the elongation can be increased 2 times. Scientists believe that these strange phenomena are derived from the material after the crystalline, amorphous structure after a new kind of material structure - nanostructures. This new form of physical structure is a German scientist who has long been involved in the study of crystal physics, conceived in a journey through the vast and marginal desert. Open, lonely natural environment, make him think
