摘　　要：火灾探测器的价值在于能及时响应真实火灾而不响应干扰源的激励。离子和光电感烟探测器对于进入感应腔内的烟颗粒有着一定的响应能力,但却不容易区分干扰源产生的烟颗粒。本文主要通过FE/DE平台上一系列的实验,测量了离子感烟探测器、光电感烟探测器在不同环境下的抗干扰性,并进行了一些理论分析。The worth of the fire detector is determined by its ability of sensitive respondence to real fires and immunity to stimuli generated from nuisance sources. Ionization and photo-electric smoke detectors react in some degree to all the particles that enter the sensing chamber, however, by themselves, the detectors can not distinguish smoke from a nuisance aerosol. By a series of experiments in the Fire Emulator/Detector Evaluator, we get the nuisance immunity features of ionization and photo-electric smoke detector, with some theoretical analysis conducted.
