【正文】 的嚴重事件。s Zhang Weiwei, argue that the oneparty system does not need a democratic mandate because it has “performance legitimacy”, derived from improving the lot of ordinary solutions to haze The pollution problem suggests the leadership needs urgently to adopt a “greener” measure of “performance”.It is not just the rivers are often polluted by industrial waste, and the country has had a series of foodsafety leaders and businesspeople also need to change the past 30 years, every provincial governor with an eye on a big job in Beijing knew that they would be judged by the local growth them that they should now care as much about their city39。we make apologies to polluted riverthe mother who nurtures us, for it is stink because of contamination and it may be unwilling to continue to nurture us。霧霾天氣對人的情緒會產(chǎn)生影響,霧霾天時太陽光被大氣顆粒物散射和吸收,使日照減少,容易增加人的瞌睡感和抑郁感。霧霾天氣不僅會影響農(nóng)業(yè)生產(chǎn),還會造成視程障礙,甚至引發(fā)交通事故。第四,垂直方向的逆溫現(xiàn)象。霧霾給人們生產(chǎn)生活及交通安全帶來了嚴重的危害。霧霾現(xiàn)象頻發(fā)。主要市級城市有鄭州、開封、許昌、平頂山、漯河、周口、舞陽、駐馬店、信陽等地。霾是指懸浮在大氣中的大量微小塵粒、煙粒或鹽粒的集合體,使空氣渾濁,水平能見度降低到10km以下的一種天氣現(xiàn)象[1]。haze situation。適當(dāng)補充點兒維生素。減少污染廢氣排放和廢氣處理。霧霾的防治:在現(xiàn)在的技術(shù)經(jīng)濟條件下,不能對氣象條件進行有效干預(yù),解決霧霾污染問題只能依靠減少污染物排放量,也就是要全方位地控制各種大氣污染物的排放行為,不斷減少各種細顆粒物及其前體污染物的排放量。霧霾的影響:霧霾會引起急性上呼吸道感染、急性氣管支氣管炎及肺炎、哮喘發(fā)作,誘發(fā)或加重慢性支氣管炎等。霧霾天氣形成原因其中既有氣象原因,也有污染排放原因。參考文獻:[1] : 氣象出版社, 1979 [2] 吳兌. 霾與霧的識別和資料分析處理[J]. 氣象學(xué)報,2008,27(3): 327 -330.
