| 摘 要： | 烟幕粒子的质量消光系数是表征其遮蔽能力的重要参数。本文提出运用红外傅立叶变换光谱仪检测微粒红外吸光度，该技术基于红外定量分析原理，无需使用烟箱装置，在实验室内即可完成对新型气溶胶粒子消光性能的快速测试和评估。将一定质量的粉末样品均匀地分散在某种有机溶剂中，制作成悬浊液，运用红外光谱仪扫描后得出相应的吸收谱图。通过分析、计算求出粒子在测试波段的质量消光系数，所得结果与烟箱试验数据吻合较好，从而证实上述测试方法准确、可靠，测试成本较低，可用于新型烟幕材料衰减性能的初步鉴定、评判，是传统测试技术的辅助和补充。

| Abstract: | The mass extinction coefficient of smoke particles is an intrinsic physical parameter to character shielding property. Infrared Absorbency of aerosol particles is measured by Fourier transform infrared spectrometer in this article. On basis of quantitative analysis,a kind of method is proposed to rapidly and accurately measure the attenuation property of particles without smoke box in laboratory. Certain mass powder is dispersed in organic solvent,and then suspended solution is scanned by FTIR. According to spectrograms,the extinction coefficients of materials are calculated at infrared frequency. Obtained results are accorded with data measured by smoke box. Consequently,it is proved that above-mentioned experiment method is exactly and reliable. This testing technology can be used to quickly choose and identify shielding effects of new aerosol materials. To traditional test method,it is supplementary and auxiliary. |
