直径在大于1 μ m且小于1 μ m范围内的超细颗粒可称为纳米颗粒。化学纯的纳米粒子通常是通过在受控环境中蒸发和冷凝来生产的。科学工程师可能认为纳米粒子是适合制造宏观产品的微米级元素的材料，而科学家则考虑纳米粒子的原子和电子结构和性质。我们先前提出了一种称为气体沉积工艺的沉积和/或侵蚀工艺，其中夹带在微小载气射流中的纳米颗粒碰撞并沉积到目标衬底上（Jpn. J.应用物理学，23（1984）L910-L912）。电路图案（大约40 μ m宽）、电容器（BaTiO 3）、氧化物超导接触（钇、铋）等是该工艺的组成部分的示例。将讨论在该过程中的纳米颗粒的热行为的分析。我们认为，这一过程或任何其他无污染和局部化的过程应该作为宏观世界和原子世界之间的桥梁技术加以开发。
Ultrafine particles having diameters in the range larger than 1 mum and less than 1 mum can be called nanoparticles. Chemically pure nanoparticles are usually produced by evaporation and condensation in a controlled environment. Scientific engineers may consider nanoparticles as materials suitable for the fabrication of micrometer-sized elements of macroproducts, while scientists consider the atomic and electronic structure and properties of nanoparticles. We previously proposed a deposition and/or erosion process called the gas deposition process, where nanoparticles entrained in a tiny carrier gas jet collide and are deposited onto a target substrate (Jpn. J. Appl. Phys., 23 (1984) L910-L912). The electrical circuit pattern (approximately 40 mum width), the capacitor (BaTiO3), oxide superconducting contacts (yttrium, bismuth) etc. are examples of components of the process. Analysis of the thermal behavior of nanoparticles during the process will be discussed. We believe that this process or any other pollution-free and localized process should be developed as a bridging technology between the macro and atomic worlds.
