Mpweya umene dzenje - vuto masiku ano

Mpweya umene uli mu mpweya wa zinyalala, amene panamveka ndi mabizinezi, ndipo ndi mankhwala oopsa. Ndi chinthu wokangalika, ndipo angathe kuyambitsa dzimbiri kwa zinthu structural nyumba zonse zitheka. Komabe, Mpweya umene mu m'mlengalenga n'kukhala ndi lofunika kwambiri, popanda moyo padzikoli chabe kulibe.

Stratosphere otchedwa wosanjikiza mumlengalenga, chomwe chimatsatira amene limene tikukhalali. Kumtunda chimakwirira ozoni, wokhutira mu wosanjikiza ichi - 3 mamolekyulu pa mamolekyulu 10 miliyoni yosiyanasiyana ya mpweya .. Ngakhale kuti ndende ndi otsika, Mpweya umene imagwira ntchito chida - ndi angathe kutchinga njira kunyezimira ultraviolet akubwera kuchokera malo imodzi ndi dzuwa. UV cheza kungasokoneze pa kapangidwe ka maselo amoyo ndiponso angachititse chitukuko cha matenda monga ng'ala, khansa ndi matenda ena oopsa.

Pa maziko a chitetezo a wosanjikiza Mpweya umene ndi mfundo zotsatirazi. Pa nthawi imeneyi, pamene njira ya cheza ultraviolet anapeza molekyulu mpweya, pali zimene akuwaza mu maatomu awiri oxygen. Maatomu chifukwa amaphatikizidwa ndi mamolekyulu undigested, kulenga Mpweya umene mamolekyulu ongokhala maatomu 3 oxygen. Pa msonkhano kunyezimira ultraviolet ndi tinthu Mpweya umene kuwononga maatomu womaliza atatu oxygen. mamolekyulu makokedwe akuwaza limodzi ndi kumasulidwa kwa kutentha, ndi padziko lapansi, iwo akwaniritsa.

Mpweya umene dzenje

The ndondomeko ya kusintha mpweya mu Mpweya umene ndi mosemphanitsa amatchedwa mpweya-Mpweya umene mkombero. njira yake ndi moyenera Komabe, kusintha zazikulu malingana mphamvu cheza dzuwa, ndi nyengo ya masoka achilengedwe, monga kuphulika chiphala. Asayansi kuona kuti luso anthu kukhala kungasokoneze wochindikala. Mpweya umene wakuta wakhala analembedwa zaka khumi zapitazi mu malo ambiri. Nthawi zina, yasowa kwathunthu. Kodi akhoza kuchepetsa zoipa zimakhudza anthu pa mphete anati?

Mpweya umene mabowo zimachitika chifukwa chakuti ndondomeko chiwonongeko cha wosanjikiza atetezeke amapezeka kwambiri kwambiri kuposa m'badwo wake. Ichi ndi chifukwa chakuti mu moyo anthu m'mlengalenga ndi wowonongedwa ndi mankhwala osiyanasiyana Mpweya umene-akuwononganso. Izi koposa zonse, chlorine, bromine, fluorine, mpweya ndi wa hydrogen. Asayansi amakhulupirira kuti mankhwala chlorofluorocarbon ndi kuopseza waukulu wosanjikiza ozoni. Iwo ankagwiritsa ntchito mu kachitidwe refrigeration, solvents mafakitale, conditioners mpweya ndi zitini aerosol.

Chloro, kufika Mpweya umene amachitira ndi Mpweya umene tinthu kucheza. The mankhwala anachita amapanga okusayidi chlorine ndi molekyulu oxygen. Atakumana chlorine monoxide ndi ufulu mpweya kumachitika mogwirizana ina imene chlorine adzamasulidwa, ndipo pali mpweya molekyulu. Kenako unyolo akubwereza chifukwa chlorine sangathe kupitirira malire a m'mlengalenga kapena pansi. Mpweya umene mabowo - chotsatira cha yafupika ndende ya amafotokozera chifukwa pogawanikana pamawere ake mofulumira maonekedwe ake mu wosanjikiza m'nyanjazi mlendo yachilendo.

kutanthauzira

Yaikulu Mpweya umene dzenje pa Antarctic anapeza. kukula ndi pafupifupi wofanana ndi malo m'dzikoli. Kudera limeneli si anthu koma asayansi atadandaula kuti lisaoneke ingafalire m'madera ena a dzikoli, kwambiri asezare. Ndi zinadzala ndi kuwononga chilengedwe ndi imfa ya Earth.

Pofuna kupewa kuchepetsa wosanjikiza Mpweya umene uyenera uyambe kuchepetsa akuwononganso zinthu panamveka kuti m'mlengalenga. Mu 1987 iye anali yolembedwa ndi Montreal pangano m'mayiko 180, amene amathandiza kuti kuchepetsa mpweya zinthu zokhala ndi chlorine, mu mode phased. Tsopano una Mpweya umene ndi kuchepetsedwa ndi asayansi kuti akukhulupirira kuti zinthu uphungu mu 2050.
