雾霾的形容词用英语怎么说

The market for dust masks and air purifiers is booming in Beijing because the capital has been shrouded for several days in thick fog and haze。

近几日北京持续被浓重雾霾笼罩,市场上防尘口罩和空气净化器的销量剧增。

雾(fog)和霾(haze)是这两天我们经常听到的两个词,二者的区别为:雾的相对湿度(the relative humidity)一般在90%以上,而霾在80%以下,但通常两者并存。能见度(visibility)在1公里以下的称为雾,1公里以上但小于10公里的属于灰霾(dust haze)现象。

近两日,部分地区的空气质量指数(air quality index, AQI)可能达到极重污染,北京多地PM2.5浓度“爆表”。PM2.5就是指“可入肺颗粒物”,PM的英文全称为particulate matter(微粒物、悬浮微粒),PM2.5就是指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alveoli of the lungs(肺泡),它的直径还不到人头发丝粗细的1/20。PM2.5主要来自burning of fossil fuels in vehicles(机动车燃油), power plants(发电厂) 以及 various industrial processes(各类工业生产)。

在口罩的各项指标中,大家最关心的是对颗粒物的过滤效率。所以选购口罩前可以多了解一下各种标准对应的颗粒物过滤效率。NIOSH中的“N95”表示对小至0.3微米的颗粒物过滤效率达95%。实际上, ASTM和FFP标准中的最高级别对颗粒物过滤效率的要求都是高于NIOSH N95的。比如ASTM Level 3要求对小至0.1微米颗粒物的过滤效率达98%。美国进口普卫欣天 猫有效防雾霾

1、雾霾天气少开窗。出门在外一定要戴口罩,平常多饮水,可多泡饮菊杞茶这类中医茶饮,预防疾病,多食用水果,从外回家后要深度清洁皮肤和头发,此外喜爱晨练以及买菜遛弯的老年人要注意减少出门,因为雾霾对老年人的身体危害极大。

2、外出戴口罩

3、多喝茶

4、适量补充维生素D

5、饮食清淡多喝水

6、多吃蔬菜

7、在雾霾天气尽量减少出门[6]

8、开车注意车速

9、出门时,做个自我防护,佩戴专门防霾的PM2.5口罩、防霾鼻罩,过滤PM2.5,随时随地呼吸新鲜空气。

10、避免雾天锻炼。可以改在太阳出来后再晨练。也可以改为室内锻炼。

11、患者坚持服药。呼吸病患者和心脑血管病患者在雾天更要坚持按时服药

12、别把窗子关得太严。可以选择中午阳光较充足、污染物较少的时候短时间开窗换气。

13、尽量远离马路。上下班高峰期和晚上大型汽车进入市区这些时间段,污染物浓度最高。

14、补钙、补维D,多吃豆腐、雪梨等

阻止雾霾的措施英语作文

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 ,we should strengthen air monitor to lower the levels of small particulate pollutants.Second,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.

Third,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.awareTM

关于雾霾天气的英语作文初中

The environment around us has suffered serious damage, take recently around the fog haze weather.

On January 28, China's central and eastern regions in a broad range of haze weather, the ash haze area exceeds 100 square kilometers. The national meteorological center outside the fog warning, also issued a haze of blue warning signal

Is that when the haze of relative humidity is not big, and the relative humidity in the fog is saturated (such as the presence of a large number of condensation nuclei, relative humidity 100% saturated) may appear not necessarily.

Haze weather graphic symbol average relative humidity is less than 80% when the atmospheric turbidity of blurry vision led to the deterioration of visibility is caused by haze, when relative humidity is more than 90% of atmospheric turbidity blurry vision led to the deterioration of visibility is caused by fog, when relative humidity between 80-90% of atmospheric turbidity blurry vision led to the deterioration of visibility is caused by a mixture of haze and fog together, but its main component is haze. The thickness of the haze is thick, up to 1-3 km. Haze and fog, cloud, with no obvious boundary between sky area, haze particles distribution is more even, and the scale of the ash haze particles is small, from 0.001 micron to 10 microns, the average diameter of about 1 to 2 micron, invisible to the naked eye of air floating particles. Because the particles such as dust, sulfuric acid, nitric acid haze, the longer light scattering wavelength is more, so look yellow or orange gray haze.

Haze formation has three elements: one is the physical base of granularity dust generated source. Our country has the world's largest in loess plateau area, the soil texture are the most easy to granularity dust particles. The second is movement caused by dust. The middle of the road, for example, flower beds and street after rain or water in the soil of the road opposite sides-to hold if any mud flow to the road, an hour after drying, was the wheel a spin can cause a lot of dust, even if the particulate material falls back to earth, also can by car drove by, was once again to the city. Three is the difference in dust source and movement process of concentration within a certain space, TB gathered into a haze particles with water molecules. Now, more than 350 cities in flat loess plateau region in our country, the fog haze of the three elements of structure quite abundant stocks.

My friends, the earth would damage like this? What's the reason to continue to be broken? Let's take action together to protect our earth.

我们身边的环境已经受到了严重的破坏,就拿最近各地的雾霾天气来说。

1月28日起,中国中东部地区出现了大范围的雾霾天气,全国灰霾面积超100万平方公里。中央气象台在大雾预警之外,也同时发布了霾蓝色预警信号

在于发生霾时相对湿度不大,而雾中的相对湿度是饱和的(如有大量凝结核存在时,相对湿度不一定达到100%就可能出现饱和)。

雾霾天气图形符号一般相对湿度小于80%时的大气混浊视野模糊导致的能见度恶化是霾造成的,相对湿度大于90%时的大气混浊视野模糊导致的能见度恶化是雾造成的,相对湿度介于80-90%之间时的大气混浊视野模糊导致的能见度恶化是霾和雾的混合物共同造成的,但其主要成分是霾。霾的厚度比较厚,可达1-3公里左右。霾与雾、云不一样,与晴空区之间没有明显的边界,霾粒子的分布比较均匀,而且灰霾粒子的尺度比较小,从0.001微米到10微米,平均直径大约在1-2微米左右,肉眼看不到空中飘浮的颗粒物。由于灰尘、硫酸、硝酸等粒子组成的霾,其散射波长较长的光比较多,因而霾看起来呈黄色或橙灰色。

雾霾形成有三个要素:一是生成颗粒性扬尘的物理基源。我国有世界上最大的黄土平高原地区,其土壤质地最易生成颗粒性扬尘微粒。二是运动差造成扬尘。例如,道路中间花圃和街道马路牙子的泥土下雨或泼水后若有泥浆流到路上,一小时干涸后,被车轮一旋就会造成大量扬尘,即使这些颗粒性物质落回地面,也会因汽车不断驶过,被再次甩到城市上空。三是扬尘基源和运动差过程集聚在一定空间范围内,颗粒最终与水分子结核集聚成霾。目前来看,在我国黄土平高原地区350多座城市中,雾霾构造三要素存量相当丰裕。

朋友们,地球都破坏成这样了?我们还有什么理由继续破环下去呢?让我们行动起来一起保护我们的地球吧。
