摘要
根据散射理论,描述了多种物质对红外入射的吸收问题。首先通过计算单个粒子的有关参数,推导出了一定条件下气悬体粒子随参量变化时的透射关系,进而计算出一定入射波长条件下某些远红外材料的最低透射率,从绘制的透射率曲线看出,每个连续的透射率曲线都有一个最小值。显然,选择对应的粒子直径可以为烟幕加工提供理论上优化的依据。最后给出了实验结果。
The problem of IR absorption and the way how to optimize far IR smokescreen are described. Based on particles dispersion theory, the dispersion of one material particle is calculated. Then the relationship between transmissivity and diameter of some materials is analyzed. For each material, the minimum transmissivity value is obtained. Finally, the IR absorption spectrum of the smokescreen is given and the result is satisfactory.
