Tuam Tshoj tam sim no cov ntaub ntawv tsim hluav taws xob feem ntau suav nrog cov hauv qab no.
(1) Thermal zog tsim.Lub tshuab hluav taws xob thermal yog lub Hoobkas uas siv cov thee, roj, thiab cov pa roj carbon monoxide los ua hluav taws xob.Nws cov txheej txheem tsim khoom yooj yim yog: roj combustion hloov cov dej hauv boiler rau hauv chav, thiab cov tshuaj siv hluav taws xob ntawm cov roj hloov mus rau hauv lub zog hluav taws xob.Lub zog siab ua rau kev sib hloov ntawm chav turbine.Hloov mus rau hauv lub tshuab hluav taws xob, thiab tom qab ntawd cov chav turbine tsav lub tshuab hluav taws xob tig, hloov cov tshuab hluav taws xob rau hauv hluav taws xob hluav taws xob.Thermal fais fab yuav tsum hlawv fossil fuels xws li thee thiab roj av.Ntawm ib sab, cov fossil fuel reserves yog txwv, thiab qhov ntau lawv hlawv, tsawg dua lawv ntsib qhov txaus ntshai ntawm kev qaug zog.Nws tau kwv yees tias lub ntiaj teb cov peev txheej roj yuav dhau mus rau lwm 30 xyoo.Ntawm qhov tod tes, cov roj hlawv yuav tawm carbon dioxide thiab sulfur oxides, yog li nws yuav ua rau lub tsev cog khoom thiab cov kua qaub los nag, thiab ua rau lub ntiaj teb ib puag ncig tsis zoo.
(2) Hydropower.Cov dej uas hloov lub zog gravitational ntawm cov dej mus rau hauv kinetic zog cuam tshuam rau cov dej turbine, cov dej turbine pib tig, cov dej turbine txuas nrog lub tshuab hluav taws xob, thiab lub tshuab hluav taws xob pib tsim hluav taws xob.Qhov tsis zoo ntawm hydropower yog qhov loj ntawm thaj av raug dej nyab, uas yuav ua rau muaj kev puas tsuaj rau thaj chaw ecological, thiab ib zaug ib lub pas dej loj loj tawg, qhov tshwm sim yuav raug puas tsuaj.Tsis tas li ntawd, ib lub teb chaws cov peev txheej dej kuj raug txwv, thiab lawv kuj raug cuam tshuam los ntawm cov caij nyoog.
(3) Hnub ci tsim hluav taws xob.Hnub ci hluav taws xob tsim hluav taws xob ncaj qha hloov lub hnub ci rau hauv hluav taws xob (tseem hu ua photovoltaic zog tsim), thiab nws cov ntsiab lus tseem ceeb yog "photovoltaic effect."Thaum lub photon ci rau ntawm cov hlau, nws lub zog tuaj yeem nqus tau los ntawm electron hauv cov hlau.Lub zog nqus los ntawm electron loj txaus los kov yeej lub ntiajteb txawj nqus sab hauv ntawm cov hlau ua haujlwm, khiav tawm ntawm cov hlau nto thiab dhau los ua photoelectron.Qhov no yog qhov hu ua "photovoltaic effect", lossis "photovoltaic effect" luv luv.Lub hnub ci photovoltaic system muaj cov yam ntxwv hauv qab no:
① Tsis muaj qhov sib hloov, tsis muaj suab nrov;② Tsis muaj pa phem, tsis muaj dej pov tseg;③ Tsis muaj txheej txheem combustion, tsis xav tau roj;④ Kev saib xyuas yooj yim thiab tus nqi tu qis;⑤ Kev ua haujlwm zoo thiab kev ruaj ntseg;
⑥ Lub hnub ci roj teeb ua lub luag haujlwm tseem ceeb muaj lub neej ua haujlwm ntev;
⑦ Lub zog ceev ntawm lub hnub ci zog yog qhov tsawg, thiab nws txawv ntawm qhov chaw mus rau qhov chaw thiab lub sijhawm.Qhov no yog qhov teeb meem tseem ceeb ntawm kev txhim kho thiab kev siv lub hnub ci zog.
(4) Cua tsim hluav taws xob.Cua turbines yog cov tshuab fais fab uas hloov cua zog rau hauv cov tshuab ua haujlwm, los yog hu ua windmills.Kev hais lus dav dav, nws yog lub tshuab hluav taws xob siv hluav taws xob uas siv lub hnub ci los ua cua sov thiab cua ua haujlwm nruab nrab.Nws muaj cov yam ntxwv hauv qab no:
①Renewable, inexhaustible, tsis xav tau cov thee, roj thiab lwm yam roj uas yuav tsum tau rau thermal hwj chim tiam los yog nuclear cov ntaub ntawv uas yuav tsum tau rau nuclear fais fab nroj tsuag los tsim hluav taws xob, tshwj tsis yog rau ib txwm tu, tsis muaj lwm yam noj;
②Clean, zoo ib puag ncig cov txiaj ntsig;③ Yooj yim installation nplai;
④ Suab nrov thiab pom muaj kuab paug;⑤ Nyob thaj tsam loj ntawm thaj av;
⑥ Tsis ruaj khov thiab tswj tsis tau;⑦Tam sim no tus nqi tseem siab;⑧ cuam tshuam rau noog cov dej num.
(5) Nuclear zog.Ib txoj hauv kev tsim hluav taws xob siv cov cua sov tso tawm los ntawm kev sib tsoo nuclear hauv lub tshuab hluav taws xob nuclear.Nws zoo ib yam li thermal zog tsim.Nuclear zog muaj cov yam ntxwv hauv qab no:
①Nuclear fais fab nroj tsuag tsis emit ib tug loj npaum li cas ntawm cov pa phem mus rau hauv cov huab cua zoo li fossil roj zog tiam, yog li nuclear fais fab tuag yuav tsis ua pa phem;
②Nuclear fais fab tuag yuav tsis tsim cov pa roj carbon dioxide uas ua rau lub ntiaj teb lub tsev cog khoom hnyav dua;
③ Cov roj uranium siv nyob rau hauv kev tsim hluav taws xob nuclear tsis muaj lwm lub hom phiaj tshwj tsis yog tsim hluav taws xob;
④ Lub zog ntom ntom ntawm cov roj nuclear yog ob peb lab lub sij hawm siab dua li ntawm cov fossil fuels, yog li cov roj siv los ntawm nuclear fais fab nroj tsuag yog me me thiab yooj yim rau kev thauj mus los thiab cia;
⑤Nyob rau hauv tus nqi ntawm lub zog tsim hluav taws xob nuclear, cov nqi roj nqi qis dua, thiab tus nqi ntawm cov khoom siv hluav taws xob nuclear tsis tshua muaj kev cuam tshuam rau kev lag luam thoob ntiaj teb, yog li tus nqi hluav taws xob tsim hluav taws xob ruaj khov dua li lwm txoj hauv kev tsim hluav taws xob;
⑥ Nuclear fais fab nroj tsuag yuav tsim cov khoom siv hluav taws xob siab thiab qis qis, lossis siv hluav taws xob nuclear.Txawm hais tias lawv nyob hauv ib lub ntim me me, lawv yuav tsum tau ua tib zoo saib xyuas vim muaj hluav taws xob, thiab lawv yuav tsum ntsib teeb meem kev nom kev tswv;
⑦ Lub thermal efficiency ntawm nuclear fais fab nroj tsuag yog tsawg, yog li ntau pov tseg tshav kub yog tawm mus rau hauv ib puag ncig tshaj li qub fossil roj fais fab nroj tsuag, yog li cov thermal pollution ntawm nuclear fais fab nroj tsuag yog hnyav dua;
⑧ Tus nqi peev ntawm cov chaw tsim hluav taws xob nuclear yog siab, thiab kev pheej hmoo nyiaj txiag ntawm lub tuam txhab hluav taws xob yog qhov siab;
⑨ Muaj ntau cov khoom siv hluav taws xob hauv lub reactor ntawm nuclear fais fab nroj tsuag, yog tias nws tso tawm rau sab nraud ib puag ncig thaum muaj xwm txheej, nws yuav ua rau muaj kev puas tsuaj rau ecology thiab tib neeg;
⑩ Kev tsim kho ntawm cov chaw tsim hluav taws xob nuclear feem ntau yuav ua rau muaj kev tsis sib haum xeeb thiab kev tsis sib haum xeeb.o Lub zog tshuaj lom neeg yog dab tsi?
Chemical zog yog lub zog tso tawm thaum ib qho khoom siv tshuaj tiv thaiv.Nws yog lub zog zais heev.Nws tsis tuaj yeem siv ncaj qha los ua haujlwm.Nws raug tso tawm tsuas yog thaum muaj kev hloov tshuaj lom neeg tshwm sim thiab dhau los ua lub zog cua sov lossis lwm yam kev siv zog.Lub zog tso tawm los ntawm kev hlawv roj thiab thee, kev tawg ntawm cov khoom tawg, thiab cov tshuaj hloov pauv hauv lub cev ntawm cov zaub mov uas tib neeg noj yog tag nrho cov tshuaj muaj zog.Chemical zog yog hais txog lub zog ntawm ib tug compound.Raws li txoj cai lij choj ntawm kev txuag hluav taws xob, qhov kev hloov pauv ntawm lub zog no sib npaug ntawm qhov loj thiab rov qab mus rau qhov hloov pauv ntawm lub zog hluav taws xob hauv cov tshuaj tiv thaiv.Thaum cov atoms nyob rau hauv cov tshuaj tiv thaiv compound rearrange los tsim ib tug tshiab compound, nws yuav ua rau chemical zog.Qhov kev hloov, ua rau exothermic los yog endothermic nyhuv
