摘　　要：在容积为20 m3的烟幕箱中测试了30 g纳米镍粉形成的烟幕对1.06μm和10.6μm激光的消光性能。其质量消光系数分别为1.542 m2.g-1、1.078 m2.g-1,沉降速度为1.035×10-3m.s-1,与常规材料的烟幕性能比较表明,纳米镍粉形成的烟幕消光性能好,悬浮时间长,是一种能有效干扰1.06μm和10.6μm激光的新型烟幕材料。The extinction performance of 30 g nano-Ni powder smoke to 1.06 μm and 10.6 μm laser were tested in 20 m^3 smoke chamber. Its mass extinction coefficient is 1. 542 and 1. 078 m^2·g^-1 respectively, and the sedimentation rate is 1. 035 ×10^-3 m·s^-1. Compared with the smoke performance of conventional materials such as HC, RP, oil, graphite, carbon black, nano-Ni powder smoke has better extinction capability to 1.06 μm and 10.6 μ m laser and possesses the better suspending characteristic in the air.
