【摘要】 本文研究烟幕对1.06μm、10.6μm激光的消光性能及影响因素，为探索更适用于激光遮蔽的发烟剂提供一定的思路。 通过对激光产生与传输机理的探讨，以及与红外辐射的对比，为在发烟剂设计的基础上为激光消光提供了方向。同时，选择C₆Cl₆、赤磷为发烟物的发烟剂配方，通过理论计算，得出了在绝热真空条件下的燃烧产物组成，并对其计算产物二次反应的研究讨论，探索发烟剂燃烧产物对消光效果的影响因素。通过实验测试结果，讨论了实验现象产生的原因及相应在配方设计时需要注意的问题，为探索新型激光遮蔽的发烟剂提供基础。 文中还分析了附加的组成对激光消光性能影响，通过实验系统测试了混合烟雾的消光性能。通过实验测试，发烟剂质量浓度为9.1g，10.6μm激光透过率T可以降低到30％。当发烟剂的质量为4.0g，1.06μm激光无法透过。更多还原

【Abstract】 The paper relates to the extinction properties and factors of smoke agent by burning for the laser in 1.06μm and 10.6μm bands. To provide the way for searching for the more useful smoke agent in order to extinct the laser.By discussing the produce and transportation of the laser and comparing to the infrared spectrum , the way of the extinction of the laser for smoke agent design has been reached. According to the formula of smoke agent including the phenyl-hexachloride and the red phosphorus, the composition formula of combustion smoke is calculated without heat transportation and atmosphere. Then discussing the next step reaction of the smoke agent , the factor of the extinction properties of smoke agent in different composition is researched. The indeed result of the composition formula is provided .The influence of the extinction of smoke agent by different additive substance in laser is researched. The extinction properties of the all smoke agent are tested in experiments. According to the test, for the mass of the smoke agent is 9.1g, the laser transmittance is decreased below 30% in 10.6μm band. The laser in 1.06μm band can’t transmit when the mass of smoke agent is 4.0g.更多还原
