【正文】 ady been familiar to us, especially in Beijing and in Nanjing, I experienced the haze and had a deep thought about , making use of the opportunity, I will talk it Words : Haze。solutionsi 金陵科技學院學士學位論文 and the EmbodimentThe longest distance in the world is that I couldn’t see Chairman Mao even though I am right in front of the Tiananmen!Nowadays,“”and “Haze” have already been familiar to us, especially in Beijing and of the most popular iPad apps in Beijing at present is China Air Pollution app is both addictive and checked the numbers and discovered that the AQ level, which measures fine particulates that are especially dangerous, was 250 – about five times the level deemed in Nanjing, I experienced the that time, all the middle school students had two days off to keep away from the , we university students had classes as we are stronger than middle school students, but even they are kept indoors, it is hard to escape from the harm of , let’s talk about haze in the following definition of hazeWHO guidelines say average concentrations of the tiniest pollution particlesshould be no more than 25 microgrammes per cubic is unhealthy above 100 microgrammes and at 300, all children and elderly people should remain the deterioration of air quality, haze got worse and areas incorporated haze into the fog together as weather warning fact, there is a big difference between fog and haze in some example: fog occurs when the air is humid, while haze occurs when the air is relatively dry, the relative air humidity is usually below 60%.Its formation is due to a large number of very fine uniform floating dust particles, soot, salt, the air, causing the effective horizontal visibility less than 10KM air variation haze there is no large change in the air mass, haze lasts for a long time, sometimes over more than 10 the haze, mist, dust storms, blowing sand, dust, smoke and other weather phenomena are caused by floating in the air and a lot of very fine dust or smoke particles , in effective horizontal visibility is less than sometimes it is difficult for weather professionals to distinguish order to draw the right conclusions, weather professionals must bined the weather background, sky conditions, air humidity, odor and color satellite monitoring and other factors to make a prehensive analysis, but sometimes fog and haze can harm of haze The haze will affect not only health of people but also the economic, as well as the future of , once inhaled, the tiny particles can make people more vulnerable to respiratory infections, as well as leading to increased mortality from lung cancer and heart all know that losing a family member is how sorrowful, so haze may destroy not only a person, but 金陵科技學院學士學位論文 and the Embodiment also a , a number of foreigners won’t go to China for travelling because of haze, which will bring a loss to our , the decline of economic will in turn weaken national all, economic decides politics and this way, it will be difficult for us to make China Dream e and haze are “ killer ” for patients with cardiovascular disease, especially for those who with respiratory and cardiovascular diseases, the had better not go out, nor do morning exercises, otherwise, it may induce the disease, or a heart attack, even causing point out that the reason why fog and haze are “dangerous days” for patients with cardiovascular disease is that the air pressure is low, oxygen decreases in the air when there is haze, so it39。s air quality will be difficult when their personal and political fortunes are still tied to increasing the rate of economic of the necessary environmental measures are fairly on cleaner fuel for cars and stricter emission standards for factories and power stations is enforcing those rules will involve facing down powerful interests in the stateowned energy and power nothing is done, the problem will certainly power stations continue to open at a great pace and the number of cars on the roads is projected to quadruple by latter is, of course, part of the Chinese dream of rising personal fulfillment threatens to create a collective can take some fort from the fact that notoriously polluted cities elsewhere, such as London and Los Angeles, have been cleaned the task for Beijing will be particularly , the environmentalist, says: “London39。楊文豐,

是北方的冬季燒煤供暖產(chǎn)生的廢氣；第三，是工業(yè)生產(chǎn)排放的廢氣。其中有害人類健康的主要是直徑小于10微米的氣溶膠粒子，如礦物顆粒物、海鹽、硫酸鹽、硝酸鹽、有機氣溶膠粒子等，它能直接進入并粘附在人體上下呼吸道和大氣污染與控制論文肺葉中。2013年初，著名醫(yī)學雜志《柳葉刀》（Lancet）發(fā)表了最新的全球疾病負擔評估（global burden of disease，GBD）項目研究結(jié)果。大霧天會給人造成沉悶、壓抑的感受，會刺激或者加劇心理抑郁的狀態(tài)。使區(qū)域極端氣候事件頻繁，氣象災害連連。具體可參考桐桔梗茶、桔梗湯的百度百科介紹；適量補充維生素D冬季霧多、日照少，由于紫外線照射不足，人體內(nèi)維生素D生成不足，有些人還會產(chǎn)生精神懶散、情緒低落等現(xiàn)象，必要時可補充一些維生素D；飲食清淡多喝水霧天的飲食宜選擇清淡易消化且富含維生素的食物，多飲水，多吃新鮮蔬菜和水果，這樣不僅可補充各種維生素和無機鹽，還能起到潤肺除燥、祛痰止咳、健脾補腎的作用。因此，患有心血管疾病的人，尤其是年老體弱者，不宜在霧天出門，更不宜在霧天晨練，以免發(fā)生危險；深層清潔人體表面的皮膚直接與外界空氣接觸，很容易受到霧霾天氣的傷害。污染物排放到大氣后，在一定限度內(nèi)，大氣可通過本身的物理、化學反應，把污染物稀釋和消化掉，使大氣質(zhì)量達標，但是污染排放量超出了這個限度。（１）國家應頒布強制性的法律法規(guī)，加大處罰力度。（２）完善執(zhí)法相關制度。部分貪污腐敗官員對污染環(huán)境的行為睜一只眼閉一只眼，放縱工廠、企業(yè)任意破壞環(huán)境，排放污染物，這在一定程度上助長了不法分子的行為，使污染得不到有效解決。（５）規(guī)范政府行為，加強政府責任。（２）減少機動車的使用，或者安裝汽車尾氣處理裝置。但是在霧霾天氣的催化下，油品升級必須要提上日程。那么，我們何不以清潔能源代替煤炭石油呢？專家建議，制定更多引導、扶持政策，如拓展清潔能源籌資渠道、加大自主核心技術研發(fā)、發(fā)展延伸產(chǎn)業(yè)和服務等大氣污染與控制論文
