| Abstract: | In this paper,a scattering electricity and smoke detector is influenced by photo radiant power,wavelength,particle concentration,particle size,scattering angle,dispersion volume,illuminating acreage of photo sensor,and so on.Scattering intensity refers to scattering angle and particle size.At the same time,it'll become possible to design a new scattering photo electricity and smoke detector which is sensitive to black smoke as well as the white one through backward scattering in the future. |

| Keywords: | photo electricity and smoke detector backward scattering particle diameter scattering angle |
