烟雾探测器的一个缺陷是,有烟不一定有火。有时也可能是吱吱作响的熏肉或烤焦的土司。如今,英格兰哈维尔的原子能机构(AEA)实验室研究人员们制造了一种不容易误报的火灾探测器,它探测的是一氧化碳而不是烟雾。传统的烟雾探测器以两种方式工作。其一,使用光学传感器,当烟微粒阻挡了光束时警报鸣响;其 One of the drawbacks of smoke detectors is that there is not necessarily fire in the presence of smoke. Sometimes it may be creaky bacon or scorched toast. Now, researchers at the Atomic Energy Agency (AEA) in Javier, England, have created a fire detector that can be easily misstated, detecting carbon monoxide instead of smoke. Traditional smoke detectors work in two ways. First, the use of optical sensors, when the smoke particles block the beam when the alarm sounds;
