摘要: 目前,国内公安消防部门在烟雾浓度测试时,规定使用某地生长的有一定干燥度的核桃壳,适当处理后在特定装置内进行不充分燃烧,以此作为烟源进行烟雾浓度的测量.对这种方法,我们甚感不便.

Abstract: In this paper, the relative concentration of smoke in the dynamical atate is determined by means of scatter light. Experiments demonstrate that scatter light is increased with the increase of smoke concentration in a given scale; that scatter light has to do with its wavelength, there being an optimal scatter light wavelength; and that with the change of Smoke concentration, scatter light manifests three character regions. Upon this, a model is suggested for the float system consisting of large particles of smoke. The three character regions can be explained by means of this model qualitatively.
