【摘要】 利用烟尘微粒对光的散射作用，通过测量散射光的强度，可以作为烟尘的传感信号，这种信号可用于火警初期的报警信号，进行火警探测，从而扩充了光散射现象的应用范围。更多还原

【Abstract】 The density of the smokecan be determined by measuring the intensity of light scattered by the smoke. The smoke is the early signal of fire and the detection of the scattered light canact as an alarm to fire. Therefore the application of light scattering can be broadened to include fire detection.更多还原
