很多人习惯于早晚开窗通风,其实,这个时间开窗不科学。清晨6点左右,大气中污染物的浓度依然很高,而清晨的温度又偏低,气压高,空气中的微小沙尘、不洁净气体等都被大气压力压到接近地面的地方,很难向高空散发,只有当太阳升起、温度升高后有害气体才会慢慢散去。 Many people are accustomed to window ventilation sooner or later, in fact, this time window unscientific. At around 6 am, the concentration of pollutants in the atmosphere is still high, and the temperature in the early morning is too low. With high air pressure, small dusts and unclean air in the air are all pressurized by atmospheric pressure to a point close to the ground. Emitted to high altitude, only when the sun rises, the harmful gases will slowly dissipate after the temperature rises.
