摘要
分析了现行的红外遮蔽烟幕性能测试方法中存在的问题,进而提出,利用一部高级的热像仪来对红外烟幕的遮蔽能力进行定量评估的方法——相对测量法。文中详细地介绍了测试的方法,引入了等效温度的概念,使测试的方法更合理。并通过工程事例介绍了计算过程,同时讨论了这种测试方法的优缺点和测试中存在的问题。
This paper analyses some questions in actual measuring method about capability of anti-infrared smoke screen, then introduces a way of quantitative assessment about screening capacity of anti-infrared smoke screen with an advanced thermal imager,—relative measuring means. The measuring method is presented in detail and the conception of equivalent temperature is defined to become the measuring means suitable even more. The paper gives an example to explain method by calculation, analyses merits and drawbacks and analyses some question on this means also.
