摘    要:基于二氧化硅(SiO_2)具有良好的红外透光和散射性质,探索其在单向透射烟幕配方中的应用。基于米氏散射理论分析了烟幕云团具有单向透视性能的干扰机理。其次,利用OPAG33傅立叶变换红外遥测光谱仪测试含有不同晶型SiO_2烟幕的红外透过率。结果表明:SiO_2可以作为中远距离的单向透射红外烟幕材料,在15m距离内,当烟幕位置发生变化时,红外透过率发生明显变化。说明SiO_2粒子具有良好的前向散射性能,其衰减特性与粒子的粒径和形状有一定的关系。

关 键 词:烟幕  单向透视  透过率  散射  二氧化硅

Study on Jamming Mechanism and Performance of Interference Materials with One-way Transparency
Abstract:Based on the good infrared transmission and scattering properties of SiO2,the application of SiO2 to the interference material with one-way transparency was investigated.According to Mie's scattered light theory,the interference mechanism of the smoke cloud with a one-way transparency is analyzed.OPAG 33 Fourier transform infrared spectrometer telemetry was used to detect the transmittance of smoke screen,which were placed in different positions.The experimental results show that SiO2 can be used as the infrared smoke screen,which is one-way transparent in the infrared spectrum material at long-range.Within 15 meters range,when the smoke position is changed,the transmittance spectra is different,which shows the particles of SiO2 have good scattering properties,its scattering characteristics are related with size and shape of particles.
Keywords:Smoke screen  One-way transparent  Transmittance  Scattering  Silicon dioxide
