纳米,是一米的十亿分之一。自从扫描隧道显微镜发明后,世界上便诞生了一门以0.1至100纳米这样的尺度为研究对象的前沿学科,这就是纳米科技。目前,纳米技术广泛应用于光学、医学、半导体、信息通讯等。科学家预言,纳米时代的到来不会很久,它在未来的应用将远远超过计算机工业,成为未来信息时代的核心。正如著名科学家钱学森所说的那样,纳米将会带来一次技术革命,从而将引起21世纪又一次产业革命。纳米材料自10多年前诞生以来,对人类社会和经济的发展有重要的影响。在新世纪,它将促进包括生物技术、信息技术在内的几乎所有技术的 Nano is one-billionth of a meter. Since the invention of the scanning tunneling microscope, the world has created a cutting-edge subject with a scale of 0.1 to 100 nanometers as the subject of research. This is nanotechnology. At present, nanotechnology is widely used in optics, medicine, semiconductors, information and communications. Scientists predict that the arrival of the nanometer era will not be long, and its application in the future will far exceed the computer industry and become the core of the information age in the future. As the famous scientist Qian Xuesen said, nanotechnology will bring about a technological revolution that will lead to another industrial revolution in the 21st century. Since the birth of nanomaterials more than a decade ago, it has had an important impact on the development of human society and economy. In the new century, it will promote almost all technologies including biotechnology and information technology.
