红外烟幕消光性能及选材途径分析

从烟雾气溶胶的光学和微物理特性角度，叙述了红外烟幕技术的基本原理，通过对影响微粒消光性能的主要因素分析，提出了抗红外烟火剂选材的原则和技术途径。研究表明，折射率、颗粒形状和大小在决定红外烟幕的悬浮性能和衰减性能中起重要作用，该原则和途径对红外烟幕的研究和生产具有指导意义。

Extinction Property of Par ticulate and Technique Path forChoosing Material of IR Smoke Screen

The paper introduced the fundamental theory of the IR jamming technology with the approaches of optical and characteristics of smoke aerosol. The influence factors of IR extinction property are discussed, based on which some principles and techniques for choosing the material of IR smoke screen are put forward. The study shows that refractive index, shape and size play important roles in determining the smoke performance of float and attenuation. The method offers actual significant guidance to the study and production of infrared smoke.
