摘要
为了减少烟幕温度对8-14μm波段烟幕透过率的影响,分析了有红外辐射源和没有红外辐射源的燃烧型红外烟幕的透过率。结果发现两种情况下5 g发烟剂被点燃后的透过率分别是40%-50%和15%-20%,燃烧形成的红外烟幕导致烟幕云团具有很强的红外辐射。为此提出了减差修正法,烟幕的透过率通过减去没有红外辐射源时的透过率得到修正,5 g发烟剂的透过率减小为25%-35%。
To reduce the effects of smoke temperature on the transmittance measurement in 8 - 14 μm waveband, the transmittanees of infrared smoke was analyzed with and without infrared radiation source. Results show that the transmittanees of 5 g smoke agent is 40% -50% and 15% -20%. And the infrared smoke formed by burning leads to smoke cloud with a strong radiation. Then, a different correcting method was carried out. The transmittance is corrected by subtracting from the transmittance of infrared smoke without infrared radiation source, and transmittance of the smoke agent with infrared radiation source decrease to 25% -35%.
