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。
According to the theory of scattering, the absorption of many kinds of materials on infrared incident is described. Firstly, by calculating the parameters of a single particle, the transmissivity relationship of the particles of aerogels under certain conditions with the change of parameters is deduced. Then the minimum transmittance of some far-infrared materials under certain incident wavelength is calculated. From the calculated transmittance The curve shows that each successive transmittance curve has a minimum value. Obviously, the choice of the corresponding particle diameter can provide theoretically optimized basis for smokescreen processing. Finally, the experimental results are given.
