手机是一种无线电通讯工具,无线电发射机发射出的无线电波(射频电磁辐射)能使接受无线电的天线产生射频电流。当射频电流在金属导体间环流时,遇有锈蚀或接触不良,就会产生射频火花。只要射频火花持续1微秒以上、能量大于6毫瓦就会引燃甲烷与空气的混合气。由于汽油是易挥发性物质,在油气罐及天然气管道泄漏而形成的可燃气危险区,手机产生的射频火花很容易引起爆炸,导致灾害的发生。当加油站通过油枪向汽车或摩托车油箱注加汽油时,原来空油箱内的油气便向外飘散,加之新注入的
A cell phone is a radio communication device. The radio waves emitted by a radio transmitter (radio frequency electromagnetic radiation) can cause the radio antenna to generate radio frequency current. When the RF current circulating between the metal conductors, in case of corrosion or poor contact, it will produce radio frequency sparks. As long as the RF spark lasts more than 1 microsecond, an energy greater than 6 milliwatts will ignite a mixture of methane and air. As gasoline is a volatile substance, the radio frequency sparks generated by mobile phones are likely to cause an explosion and lead to the occurrence of disasters due to the danger zone of combustible gas formed by the leakage of oil and gas tanks and natural gas pipelines. When the gas station through the oil gun to the car or motorcycle fuel tank injection of gas, the original empty tank of oil and gas will be released to the outside, coupled with the new injection
