摘要
本文根据光在烟雾中传播的能量守恒、视觉对比度、烟雾的生成率等推导出烟雾的遮蔽效应公式,进而获得了发烟剂的示性参数遮蔽能力(TOP).根据本文研究内容建立的实验技术,测得了各类发烟剂的遮蔽能力值,温度25℃±1℃,相对湿度80%±2时,黄磷的遮蔽能力为1050.2?m^2/kg.目视法和光电法在原理和实测中得到统一。测试精度在±4%之内。
This paper derives the equation for obscuringeffect in accordance with the conservation of energy in aecr-osol transmission, the visual contrast and the yield factor ofsmoke. consequsntly the obscuring Power of the smoke agsnt maybe obtained. The experimental technique by the Paper is used tomeasure the values of the obscuing Power for various kinds ofsmoke agents. The temperature is 25℃±1℃ and the ralativehumidity is 80%±2. Under these conditions, the obscuring powerof yellow phosphorus is equal to 1050.2 m^2/kg. The visual methodand the photoelectric method may be unified both in Principlesand in the actual mesurement. The mesurement precision iswithin ±4%.
