美国开发出一种红外检测器，它能区分出是真正燃烧着的火，还是其它热源（诸如燃着火的煤气灶或热铁），故而可能比一般烟火检测器能更早地发现失火，从而采取消防措施。将该检测器的红外波长调整到９００～１０００ｎｍ火焰发射出辐射的范围，就能区分是火焰还是热源，也... The United States has developed an infrared detector that can tell whether it is a real burning fire or another heat source such as a gas stove or hot iron that burns a fire and may detect a fire earlier than normal fireworks detectors Take fire fighting measures. The detector infrared wavelength is adjusted to 900 ~ 1000nm flame emitted radiation range, you can distinguish between flame or heat source, also ...
