人的活动绝大部分时间是在室内,因此室内空气新鲜程度对人的身心健康影响很大。有些人认为室内多养几盆花草,空气会更新鲜。理由是人呼出二氧化碳,花草则吸二氧化碳放出氧气。其实不然,绿色植物包括花草都具有双重作用,一是光合作用,二是呼吸作用。在进行光合作用时,它吸进二氧化碳,吐出氧气,进行呼吸作用时,则吸进氧气,吐出二氧化碳。而花草的光合作用,只有在阳光下进行,呼吸作用却每时每刻都不能停顿。特别在夜间,室内的花草会猛烈地进行呼吸,这必然使室内空气的氧气减少,二氧化碳增多,影响人的健康。所以,在室
The vast majority of human activities are indoors, so the freshness of indoor air has a great impact on people’s physical and mental health. Some people think that if you have more pots and flowers in the room, the air will be more fresh. The reason is that people exhale carbon dioxide, flowers take carbon dioxide release oxygen. In actual fact, green plants, including flowers and plants have a dual role, one is photosynthesis, the second is breathing. In the photosynthesis, it inhaled carbon dioxide, spit out oxygen, respiration, the inhalation of oxygen, spit out carbon dioxide. The photosynthesis of flowers, only in the sun, breathing, but can not pause at all times. Especially at night, indoor plants will violently breathe, which will inevitably reduce the indoor air oxygen, carbon dioxide increased, affecting human health. So, in the room
