mechanism of nanoparticles insulate infrared and electromagic wave has two main aspects: ? The size of nano particle is much smaller than the infrared‘s and radar wavelength’s, so the wave transmissivity(透射率) of nanoparticles materials is much stronger than conventional materials‘. This greatly reduced wave reflectivity(反射率) and weakened the received reflection signals of infrared and radar, achieving the effect of stealth. ? The surface area of nanometer particle material is much larger than conventional coarse powder39。納米技術(shù)在軍事上的運(yùn)用 Nanotechnology in Military Application 張玉麒 龔曉怡 黃楠楠 ? Appearance of nanotechnology indicates that humans make progress from micron(微米 ) level perates into the atomic(原子 ), molecular (分子 )level of the nanometer level, manipulating single atom and molecule according to their own desires finally and realizing effective control on mesoscopic world(介觀世界) . As a significant technology in 21st century, although present condition of nanotechnology is not mature enough, it still has obvious potential in military, greatly stimulating people to seek nanotechnology applications in military. Nano car Manufacture of Catalysts(催化劑 ) ? The technical principle: Nanometer particle has a small size and larger than specific surface area, thus increasing the contact surface of the chemical reaction and the surface effective reaction center can be widely used as catalyst. Moreover, nanocatalyst has high chemical activity, plex grain microstructure( 微觀結(jié)構(gòu) ) , the unique crystal structure and surface properties of the nan
