Lub ecological teeb meem ntawm txoj kev siv ntawm tshav kub xyaw. txoj kev tshuaj

Cov Xwm Conservancy - ib tug tseem ceeb ua hauj lwm, vim hais tias cov qib ntawm tus civilized ntiaj teb no rau pem hauv ntej ua rau lub inevitable teeb meem thiab txaus ntshai nyob rau hauv lub qhov teeb meem ntawm ib puag ncig kev ua qias tuaj. Cov lwm yam kev piam sij ntawm ib qho ntawm cov thawj qhov chaw nyob los ntawm cov ib puag ncig teeb meem txuam nrog rau kev siv ntawm tshav kub xyaw.

Yuav ua li cas teplodvigateli rau peb

Txhua txhua hnub, peb nrog lub tshuab tsav tsheb lub tsheb, ships, industrial machinery, railway locomotives thiab aircraft. Nws yog ib lub zoo li thiab thoob plaws siv thaum tshav kub kub xyaw sai sai propelled kev ua lag luam rau pem hauv ntej.

Lub ecological teeb meem ntawm txoj kev siv ntawm tshav kub xyaw yog hais tias lub thermal zog emissions yuav inevitably ua rau cua sov ntawm lub surrounding khoom, nrog rau cov cua. Zaum tau tawm tsam nrog lub teeb meem ntawm lub melting ntawm glaciers thiab hiav txwv theem sawv, piv txwv tias yog ib tug loj tshaj nyob rau hauv tej yam ntawm tib neeg kev ua ub no. Cov kev hloov nyob rau hauv cov xwm yuav ua tau kom ib tug kev hloov nyob rau hauv lub tej yam kev mob ntawm peb lub neej, tab sis nyob rau hauv cov kev phem ntawm hais tias txhua txhua xyoo lub zog noj qab.

Qhov twg thaum tshav kub kub xyaw siv

Tsheej lab ntawm cov tsheb nyob rau hauv lub internal combustion xyaw koom nqa coob uas xam nrog thiab cargo. Nyob rau railways khiav haib locomotives, dej-paths - ships. Aircraft muab piston, turbojet thiab turboprop xyaw. Foob pob ua ntxaij xyaw "thawb" mus rau hauv chaw noj, ships thiab satellites. Internal combustion xyaw nyob rau hauv ua liaj ua teb combines mounted rau, siv noj, tsheb laij thiab lwm yam khoom.

Lub ecological teeb meem ntawm txoj kev siv ntawm tshav kub xyaw

Siv tus txiv neej lub tsheb teplodvigateli, tsheb ntau lawm, siv cov roj-turbine propulsion systems, aircraft thiab community launch tsheb, dej muaj kuab paug hlab ntsha - tag nrho cov ntawm no catastrophically puas ntxim rau cov ib puag ncig.

Firstly, thaum cov cua nyob rau hauv lub combustion ntawm thee thiab roj yog faib nitrogen thiab leej faj tebchaw muaj teeb meem rau tib neeg. Ob, cov txheej txheem siv nyob rau hauv atmospheric oxygen cov ntsiab lus nyob rau hauv cov huab cua uas vim rau qhov cov nco.

Lub emissions ntawm teeb meem tshuaj mus rau hauv cov cua - tsis tsuas yog qhov zoo tshaj yuav kom ua qhov xwm ntawm tshav kub xyaw. Qhuav ntawm cov neeg kho tshuab thiab hluav taws xob lub zog tsis tau nqa tawm tsis muaj tshem tawm ntawm qhov chaw ntawm tseem ceeb nyiaj ntawm tshav kub, uas muaj peev xwm tsis ua rau ib qho kev nce nyob rau hauv nruab nrab kub nyob rau hauv lub ntiaj teb no.

Thaum tshav kub kub kuab paug yog compounded los ntawm qhov tseeb hais tias lub combustible tshuaj tsub kom lub concentration ntawm cov pa roj carbon dioxide nyob rau hauv cov cua. Qhov no nyob rau hauv lem ua rau yus lub emergence ntawm lub "tsev cog khoom nyhuv." Ntiaj teb no ua kom sov yog ua ib tug tiag tiag kev hem thawj.

Environmental teeb meem ntawm kev siv thermal machines lus dag nyob rau hauv lub fact tias cov combustion ntawm cov roj yuav tsis tau ua kom tiav, thiab nws yuav coj mus rau qhov kev tso tawm mus rau hauv cov pa peb qus ua pa, cov ntoo tshauv thiab muaj hmoov quav plaub ya ri. Raws li statistics, cov thoob ntiaj teb txhua xyoo fais fab nroj tsuag huab cua tawm mus rau hauv ib tug 200 Zeb. Thiab ntau yam ntxiv tons ntawm tshauv 60 Zeb. Tons ntawm cov leej faj oxide.

Environmental teeb meem txuam nrog rau kev siv ntawm tshav kub xyaw, ua kom daws tau tag nrho cov civilized lub teb chaws. Peb paub qhov tseeb zog-saving technology los mus txhim kho tshav kub xyaw. Raws li ib tug tshwm sim, lub zog tau rau zus tau tej cov tib khoom yog zoo heev txo, txo teeb meem ntxim rau cov ib puag ncig.

Thermal fais fab nroj tsuag, nrog combustion xyaw ntawm tsheb thiab lwm cov cav tov nyob rau hauv loj qhov ntau tso rau hauv lub chaw thiab ces mus rau teeb meem av rau tag nrho cov nyob twj, piv txwv li, cov tshuaj, sulfur compound (lub combustion ntawm thee), cov pa roj carbon monoxide CO, nitrogen oxides thiab lwm tus neeg. tsheb xyaw txhua xyoo emit txog peb tons ntawm cov hlau lead.

Nyob rau hauv nuclear fais fab nroj tsuag siv ib tug txawv ib puag ncig qhov teeb meem thermal machines - kev ruaj ntseg thiab tej khib nyiab pov tseg.

Vim lub siab heev zog noj, ib co thaj tsam muaj coob tus muaj peev xwm ntawm nws tus kheej-purification ntawm lawv tus kheej airspace. Kev khiav hauj lwm nuclear nroj tsuag pab txo emissions, tab sis rau chav turbines yuav tsum tau lossis loj nyiaj ntawm cov dej thiab ib tug loj qhov chaw nyob rau hauv lub pas dej rau cov cua txias lub tso chav.

Txoj kev uas cov tshuaj

Tu siab, noob neej yuav tsis renounce siv thaum tshav kub kub xyaw. Qhov twg yog qhov tawm? Yuav kom siv ib tug kev txiav txim ntawm qhov ntau tsawg roj, uas yog, kom txo hwj chim noj, nws yog tsim nyog los ua rau kom cov efficiency ntawm lub engine rau tib lub chaw ua hauj lwm. Lub sib ntaus tawm tsam tus tsis zoo los ntawm kev siv ntawm tshav kub xyaw tsuas yog ua rau kom cov efficiency ntawm lub zog siv thiab switching rau lub zog txuag technologies.

Nyob rau hauv Feem ntau, nws tsis yog lawm hais tias lub ntiaj teb no tej teeb meem ntawm txoj kev siv ntawm tshav kub xyaw tsis tau solved. Ib tug zuj zus ntawm hluav taws xob locomotives hloov pa u; ua nrov tsheb roj teeb; kev lag luam nyob rau hauv lub zog-npaum technologies yog tswvcuab. Nws yog vam hais tias yuav muaj eco-friendly aircraft thiab foob pob ua ntxaij xyaw. Governments ntawm ntau lub teb chaws yog siv los ntawm thoob ntiaj teb ib puag ncig tiv thaiv kev pab cuam tiv thaiv av pa phem.
