| 摘 要： | 针对太空环境高真空的特殊性，为了研究抗红外烟幕在太空中的适用性，通过试验研究了不同真空度下，燃烧型抗红外烟幕对近红外波段(0．76—0．95μm)辐射的衰减性能，结果表明，烟幕透过率随着真空度由0．1MPa升高到0．04MPa逐渐增大，并且各相邻真空度间的透过率增幅基本一致；分析表明随着真空度的升高、烟幕炭黑含量的减小、烟幕质量浓度的降低，烟幕红外衰减性能降低。

| Abstract: | Aiming at the particularity of high vacuum and the applicability of the anti-IR smoke in outer space, the NIR attenuation performance of pyrotechnic anti-IR smoke was studied under different vacuums. (Experiment) results show that the smoke transmittance increases with the increasing of vacuum from 0.10 MPa to 0.04 MPa,and the increase amplitude between the near vacuum intervals is approximately equal. Analysis results show that the increasing vacuum,decreasing smoke mass concentration make the smoke NIR attenuation performance reduced. |
