纳米科技为什么要进行这方面研究,它的意义何在呢,我们知道著名的科学家爱因斯坦曾经说过,他说未来科学的发展,无非是继续向宏观世界和微观世界进军。那么宏观世界是什么?宏观世界就是说我们人类的肉眼可以分辨出来的物体,大至宇宙,宇宙的深处。微观世界指的是原子分子,以及原子分子以下那些层次。纳米是个长度单位,如果我们把科学家目前所研究的这个物质世界的对象,都给予一个长度单位来表征出来。比如以米作为单位,那么10的25次方米大约十亿光年,这个范围是人类目前已经观测到的宇宙大致范围。如果减小到10的21次方米,大约是十万光年,在这个范围内我们可以看到银河系的全貌,到10的14次方米,这是一千亿公里,可以看到冥王星的完整轨道,那么到10的7次方米,这是一万公里,我们就可以分辨出地球的一部分,像从航天飞机上可以看到,到10的3次方米是一公里,从飞机上,我们看到分辨城市建筑物的排列,街区,到10的1次方米,这是十米,那么我们就可以看到足球场上运动员,看得很清楚,如果说我们把我们目光聚焦在运动员的腿部、膝盖,继续缩小我们的观测范围,到10的-2次方米,是一个厘米,就可以看到他腿上汗毛孔了,皮肤表面的皱纹就可以看到。再继续往下走,到10的-4次方
What is the significance of nanotechnology for conducting research in this area? We know that famous scientist Albert Einstein once said that the future development of science is nothing but to continue marching toward the macro-world and the microcosmic world. So what is the macro-world? The macro-world means that the human beings can distinguish the naked eye from the object, as far as the universe, the depths of the universe. The microscopic world refers to atomic molecules, as well as those below atomic molecules. Nanometer is a unit of length, if we give a unit of length to the object of the material world that scientists are currently studying. Take rice as a unit, for example, 10 billion 25-nanometers are about one billion light-years. This range is the approximate range of the universe that mankind has observed so far. If it is reduced to 10 times 21 meters, about one hundred thousand light years, in this range we can see the whole picture of the Milky Way, to 10 14 meters, which is one hundred billion kilometers, you can see the Pluto Complete orbit, then to 10 7 of 7 meters, which is 10,000 km, we can distinguish a part of the earth, as can be seen from the space shuttle, to 10 3 km is one kilometer from the plane , We see that we can see the arrangement of urban buildings, blocks, 10 meters to 10, which is 10 meters, then we can see the football players on the field, see clearly, if we put our eyes on the Athletes leg, knee, continue to narrow our observation range to 10 -2 -2 meters, is one centimeter, you can see his legs sweat pores, the skin surface wrinkles can be seen. Go ahead and go down to the 10th-4th power
