磷烟雾的全遮蔽能力检测与分析

Testing and analysis for total obscure power of phosphorus-derived smoke

发烟剂的全遮蔽能力TOP(total obscuring power)值是国内外烟幕技术领域表征发烟剂生成的烟雾对人眼视觉产生遮蔽能力的特征参数。基于辐照度测量法成功研制了烟雾全遮蔽能力检测系统。该系统可以实现对TOP的全过程自动化测量,具有可靠性强,工作效率高,实时性好和可扩展性强等优点。在温度26℃、相对湿度80%的条件下对黄磷烟雾的TOP进行了检测,所得到的测试结果与经验值很接近。

In the field of smoke screen technology, the total obscure power （TOP） is a characterization parameter of smokescreen obscure power for human visual. A smokescreen TOP testing system, which can implement the automatic TOP measurement, was developed based on the irradiance measurement technology. This system is stable, efficient, real-time and reconfigurable. Under the conditions of 26℃ and 80% relative humidity, a test for yellow phosphorus-derived smoke TOP was performed. It was verified that the test result conformed with the empirical value.
