摘　　要：为寻求对激光精确制导武器干扰的有效途径,研究了泡沫这种新型光电干扰介质。利用Mie氏理论,对处在军事上常用1.06μm和10.6μm激光波长上泡沫的质量消光系数与泡沫自身几种重要参数的关系进行了计算和分析。结果显示,在不同波长、不同泡沫溶液复折射率情况下,最优泡沫质量消光系数对应的泡沫球尺寸不同,而且壁厚相对较小的泡沫对激光辐射具有较好的消光效果。这一研究结果可为泡沫的战术运用提供理论基础。In order to search for the effective laser interfering techniques, foam as a new passive photo-electricity interfeting medium was studied. Using the Mie scattering theory, the relationships among mass extinction coefficients （MEC） of foam and the several important parameters of foam itself in two military laser wavelengths （1.06μm and 10.61μm） were calculated and analyzed. From the results of calculation and analysis, it shows that different wavelength and different refractive index have different condition. These results of study can provide the tactics application of foam with necessary theoretical basis.
