雾霾英语介绍

随着空气质量的恶化，阴霾天气现象出现增多，危害加重。中国不少地区把阴霾天气现象并入雾一起作为灾害性天气预警预报。统称为“雾霾天气”。其实雾与霾从某种角度来说是有很大差别的。譬如：出现雾时空气潮湿；出现霾时空气则相对干燥，空气相对湿度通常在60%以下。其形成原因是由于大量极细微的尘粒、烟粒、盐粒等均匀地浮游在空中，使有效水平能见度小于10KM的空气混蚀的现象 With the deterioration of the air quality, haze weather phenomenon to appear increasing, harm aggravated.

In fact the fog and haze in some point of view there's a big difference. Such as: appear fog air moisture; Appear when air is relatively dry haze, air relative humidity usually under 60%. The forming reason is due to a large number of very small dust particles, smoke particle, such as YanLi evenly suspended in the air, make effective horizontal visibility less than 10 km air mixed corrosion phenomenon 吸入过多可致死亡 Haze in the suction of respiratory tract after harmful to human body, long-term intake may can lead to death.

写雾霾的英语作文

冬天，北方的雾霾频繁爆发。北京等多地多次PM2.5浓度“爆表”。人们出门都带上了口罩，空气净化器也成为了现时段的热销品……以“雾霾”为题怎么写一篇作文?下面是我整理的关于雾霾的英语作文，希望能帮到大家!

During the 15 days from New Year’s Eve to Lantern Festival, Beijing was affected by smog for more than half the time, because of which people suffered a lot. On the road people drove slowly because they could not see clearly. People also suffered from many illnesses caused by smog.

The smog in Beijing has been caused by many factors, in which the increase of cars in the city area plays an important role. The carssend off a lot of poisonous gases, which in turn adds to the already seriousair pollution.

In my opinion, the number of cars should be limited.We should call on the people to use more public transport. Only in this way canwe expect to have more sunny days.

Recently,haze weather has become a daily one right here in large part of China.People are forced to wear the mask to avoid breathing poisonous air.So it is necessary to find out the reason why leads to that and work out the resolution.If we trace the cause for haze weather ,the main points are as follows .

First,china 's air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects.Second,some people just go for economic interests instead of turning out products according to relevant law and regulations.They tend to use obsolete equipment in which they are high likely to emit a great deal of wasted air.Third,across our society ,relevant protection awareness has not built up so that people havent formed a habit of using green product and saving energy as much as possible. Just for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for the haze weather.

To settle this problem,a series of meaures should be taken as follows.First of all ,we should strengthen air monitor to lower the levels of small particulate pollutants.What's more,we should enact more strict laws and regulations and keep perfecting our current law on environmental protection to regulate people 's daily action and the industrial production and punish those factories that ignore the protection and keep emitting dangerous material that cause haze.Last but not least,we should develop green and energy-saving energy to lower the emission of haze and improve air quality.

As far as I am concerned ,if we work together to be able to do such measures ,our environment will getting better and better and haze weather will vanish completely.

①haze和smog。《新牛津英语词典》给haze和smog提供的释义分别为“a slight obscuration of the lower atmosphere, typically caused by fine suspended particles”和“fog or haze intensified by smoke or other atmospheric pollutants”。haze是由细小的悬浮颗粒引起的`，而smog是指受烟或其他大气污染物影响的雾或霾。所以我们有时可以把smog当作是haze的一种。haze表示雾霾更为合理。

②AQI，air quality index。空气质量指数。

③PM2.5，particulate matter。大气中直径小于或等于2.5微米的颗粒物，可直接进入人体的肺泡。
