朋友,当你在看电视时,有时会闻到一股臭味,尤其是连续长时间观看电视,会感到有些刺鼻。这是因为电视机内的某些元件的电压高达一两万伏,如果电视机发生故障,元件受损会放出高压电,空气中的氧分子在高能量电子轰击下,便会分解出氧原子。这些氧原子,又和空气中的氧分子发生化学反应而生成臭氧,发出一股刺鼻的臭味。据有关部门测验,当空气中的臭氧的浓度达到千分之一时,就会对人体产生刺激作
Friends, when you are watching TV, sometimes smell a stink, especially if you watch TV for a long time, and you feel a bit pungent. This is because the voltage of some components in the television sets can reach as high as ten or twenty thousand volts. If the television sets break down, the components will be damaged and release high voltage electricity. The oxygen molecules in the air will be decomposed by the high-energy electron bombardment atom. These oxygen atoms, in turn, chemically react with the oxygen molecules in the air to generate ozone that emits a pungent odor. According to the relevant department test, when the concentration of ozone in the air reaches one thousandth, it will stimulate the human body
