超微粒是指粒径在1μm以下的颗粒。它在我们并不陌生,最常见的就是烟。它是那么细,那么轻,能袅袅飞升,会随风漂散。但很久以前,我们的祖先就能捕集它,利用它,制成了至今让我们引以为骄傲的墨。近年来,超微粒越来越引人注目。这是因为,它是大块物质到单个原子间的过渡形态。物质处于这种特殊的状态将会呈现出许多奇妙的性质。正是这些奇妙的性质预示着超微粒即将成为用途极广的材料。目前,我们可以把超微粒的特性归纳为三个效应:一、体积效应。这是因为物质的体积变
Ultrafine particles refer to particles having a particle size of 1 μm or less. It is no stranger to us, the most common being smoke. It is so fine, so light, can curl up, will drift with the wind. But long ago, our ancestors could capture it and make use of it to create the ink that has prided us so far. In recent years, ultra-particle more and more eye-catching. This is because it is a transitional form of bulk matter to individual atoms. Matter in this special state will show many wonderful properties. It is these fantastic properties that indicate that ultrafine particles will soon become a very versatile material. At present, we can summarize the characteristics of ultrafine particles into three effects: First, the volume effect. This is because the volume of matter changes
