你的秋天
雾霾,是一种特殊的天气现象。指空气中的灰尘、硫酸、硝酸、有机碳氢化合物等非水成物使大气混浊,视野模糊并导致能见度恶化,如果水平能见度小于10000米时,会造成视程障碍.雾气中的有毒有害物质对呼吸系统疾病患者危害很大。 大气细颗粒物主要来自直接排放的污染源和排放的污染气体二次生成。直接排放的细颗粒物主要来自如钢铁、水泥等工业生产过程和风沙扬尘等。所谓二次生成的细颗粒物,主要是由污染源排放的污染气体,如二氧化硫、氮氧化物、氨气、有机物等在一定天气条件下生成的,这部分细颗粒物的生成机制非常复杂,是目前研究的热门课题, 二氧化硫主要来自煤的燃烧,氮氧化物主要来自高温燃烧过程,只要有燃烧发生,就会产生氮氧化物。如烧煤炭、烧秸秆、烧垃圾等都会产生氮氧化物。氨气主要来自养殖业、农业生产、工业生产和自然排放。此外,风沙扬尘、炊事、烧烤等也都有影响。厨房炊事如炒菜,油在高温下蒸发、燃烧,都会产生有害有机气体和有机颗粒物。 很多年就有了,特别是重工业城市。只是以前没意识到而已。直到PM2.5曝光,然后通过网络,媒体的传播,才有了对雾霾的重视。2013年 雾霾 算是年度关键词,电视台一报道,大家就都知道这么回事了。雾霾(wù mái,英语表达为smog/haze)是雾和霾的组合词。雾霾现象常见于城市。中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报,统称为“雾霾天气”。雾霾天气形成有以下几个方面的原因。1. 大气空气气压低,空气不流动时主要因素。由于空气的不流动,使空气中的微小颗粒聚集,漂浮在空气中。2. 地面灰尘大,空气湿度低,地面的人和车流使灰尘搅动起来。3. 汽车尾气是主要的污染物排放,近年来城市的汽车越来越多,排放的汽车尾气是雾霾的一个因素。4. 工厂制造出的二次污染。5. 冬季取暖排放的CO2等污染物。雾 霾天尽量减少外出,如出行要做好防护,天,,猫有美 国进口普卫 欣帮您减少雾霾吸入。祝您新年快乐!

雾霾天气自古有之,刀耕火种和火山喷发等人类活动或自然现象都可能导致雾霾天气。不过在人类进入化石燃料时代后,雾霾天气才真正威胁到人类的生存环境和身体健康。急剧的工业化和城市化导致能源迅猛消耗、人口高度聚集、生态环境破坏,都为雾霾天气的形成埋下伏笔。现在的雾霾越来越严重的情况下,市民可以通过戴口罩来过滤。九头鹰口罩。核心技术比较过硬。

关于雾霾的英语作文
北方的雾霾越来越严重了,2017年的第一天,北京迎来的就是雾霾,有网友说甚至比上次红警还要严重。下面是我整理的关于雾霾的英语作文。
Recently, haze weather has become a daily one right here in a large part of China. People are forced to wear the mask to avoid breathing poisonous air. So it is necessary to find out the reasons which lead to that and work out the resolution. If we trace the cause of 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 laws and regulations. They tend to use obsolete equipment in which they are likely to emit a great deal of wasted air. Third,across our society, relevant protection awareness has not been built up so that people haven’t formed a habit of using green product and saving energy as much as possible. Nowadays, people rely more and more on travelling and working by car. It is well known that automobile exhaust is the main reason for the haze weather.
To settle this problem, a series of measures 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 actions and the industrial production and punish those factories that ignore the protection and keep emitting dangerous materials 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 take such measures, our environment will get better and better and haze weather will vanish gradually.
参考译文:
最近,阴霾的天气已经蔓延在中国大部分地区。人们不得不戴上面罩,避免呼吸有毒空气。因此我们有必要找出导致雾霾产生的原因并找到对策,如果我们调查雾霾天气的形成原因,主要有以下几点:首先是因为中国的空气质量标准不严格,评估因素有限所导致的。所以你会发现当前空气评估体系有缺陷。第二,有些人只是追求经济利益,而不按照有关法律和规定生产产品。他们倾向于使用过时的会发出大量的废气的'老旧设备。第三,在我们的社会中,相关保护意识还没有建立起来,人们没有形成使用绿色产品和节能的习惯,当今,越来越多的人们旅行和工作都依赖于汽车,而解决雾霾天气的关键就是汽车。
解决雾霾问题应采取一系列措施:首先,我们应该加强空气监测,降低微小颗粒污染物。其次,我们应该制定更加严格的法律法规,不断完善我们目前的环境保护法。我们应规范人们日常行为和工场的生产行为,制定好违反工厂排放规定,继续排放废气的惩罚措施。第三,我们应该发展绿色和节能能源,从而降低烟雾的排放,提高空气质量。
就我看来,如果我们能够共同采取如上的措施,我们的环境将变得越来越好,雾霾的天气将逐渐消失。
Haze is air pollution in which is mixed up with dust, smoke and other dry particles ,and it obscure the clarity of the sky and interacts with the natural environment.
This kind of air pollutant come from a variety of natural and manmade sources. Natural sources can include windblown dust, and soot from wildfires. Manmade sources can include motor vehicles, and industrial fuel burning, and manufacturing operations. The one of the main cause that touches off haze is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air become air pollution.The components that make up haze may have negative effect on people's health especially that of the children and the elderly. Also not excluded are those who have certain diseases such as asthma, allergy, and pneumonia and lung disease. Workers working in the open air have a high risk in their health.
One of effective solutions to help eliminate haze is to make some chemistry changes during the manufacturing process,so it could reduce harmful emissions which are produced by manufacturing operations

阴霾是空气污染和灰尘,烟雾和其他干燥粒子,它掩盖了清晰的天空,与自然环境进行交互。
这种空气污染物来自各种自然和人为来源。天然来源可以包括风沙、烟尘从森林大火。人为来源可以包括机动车辆、工业燃料燃烧和制造业务。触动了烟雾的主要原因之一是制造业务。许多工厂测量产生的烟雾对标准和烟雾严重影响空气成为空气污染。
雾霾危害:组件构成烟雾可能对人们的健康有负面影响特别是儿童和老人。也不排除是某些疾病如哮喘、过敏、肺炎和肺部疾病。工人工作在露天有很高的风险在他们的健康。
解决方法 :一个有效的解决方案,帮助消除烟雾是让一些化学变化在制造过程中,所以它能减少有害排放产生的制造业务。
