摘要
在烟幕性能测试评价实验室中测试分析了纳米铁粉作为烟幕干扰材料对1.06μm和10.6μm激光的消光特性。在容积为20m3的烟箱中分别喷撒30g纳米铁粉,通过测量其在不同时刻的激光透过率和烟幕质量浓度,测得纳米铁粉对1.06μm和10.6μm激光的质量消光系数分别为1.833m2.g-1,1.474m2.g-1,表明纳米铁粉对双波长激光均具有显著的干扰效果。
The extinction characteristic of nano-Fe powders smoke screen to 1. 06μm and 10.6μm laser was tested in our ＂Laboratory of Test of Smoke Screen Character＂. After 30g nano-Fe powders were sprayed into 20m^3 smoke screen chamber,their transmission rate of laser and mass concentration were measured in different time. Consequently, the mass extinction coefficients of nano-Fe powders to 1. 06μm and 10. 6μm laser were calculated, which were 1. 833m^2·g^-1 and 1. 474m^2 · g^-1 The experiment results showed that nano-Fe powder had excellent interference capability to 1.06μm and 10.6μm laser.
