傅里叶变换红外光谱仪在烟幕测试中的应用

The Application of Fourier Transform Infrared Spectrometer to the Smoke Determination

用自制的小型烟幕箱在ＦＴＩＲ光谱仪上测试抗红外烟幕剂燃烧形成的烟幕。通过动态测试烟幕不同时间的红外光谱图，得出烟幕随时间的变化规律及烟幕沉降规律。由测试同一配方不同量烟幕剂燃烧形成烟幕的红外光谱图，得出其主产物浓度与吸光度之间的定量关系，结果表明符合Ｌａｍｂｅｒｔ－Ｂｅｅｒ定律。而对不同药量烟幕剂在３个大气窗口遮蔽能力的计算，得出烟幕遮蔽能力与药量之间的定量关系。

The smoke of anti-infrared smoke agent in a self-made miniature smoke chamber was determined by using Forier transform infrared spectrometer. The smoke changing and settling regulation with time were obtained by measuring the IR spectra of smoke at different time dynamically. Through testing the smoke of different quantity of the same smoke agent, it was found that the relationship between the concentration of the main smoke products and the absorbance obeyed Lambert-Beer's Law. Finally, the relationship between the smoke screening ability and reactant agent amounts was obtained by calculating the screening ability of different amounts of reactant agent in three 'atmosphere windows'.
