Kev tua hluav taws yog ib qho kev ua ub ua no uas yog tsom rau kev tua hluav taws. Txoj kev no suav nrog ntau txoj hauv kev.
Txoj hau kev tseem ceeb ntawm kev tua hluav taws yog yuam kom tshem tawm cov nplaim hluav taws, ua kom txias ntawm qhov nruab nrab combustion thiab combustible khoom thiab depletion ntawm cov pa oxygen hauv huab cua. Tag nrho cov no yog qhov tsim nyog txhawm rau txhawm rau txo qhov kub ntawm txheej txheej sab saud ntawm cov khoom siv hluav taws xob los ntawm kev tshem tawm cov cua sov ntau. Qhov feem pua ntawm cov ntsiab lus ntawm cov pa oxygen yog txo los ntawm kev qhia cov khoom sib xyaw ntawm cov roj tsis muaj zog lossis cov vapors ntawm qee yam khoom, thiab qhov no, kev tua hluav taws yog ua tiav los ntawm kev ua kom cov oxidation ntawm cov combustible lub cev.
Ntxiv rau, ib txoj hauv kev cais cov khoom siv hluav taws xob tau dav siv, uas muaj kev tiv thaiv cov pa oxygen nkag mus rau thaj tsam oxidation. Txhawm rau ua qhov no, nws yog ib qho tsim nyog yuav tsum tau npog qhov chaw kub hnyiab nrog cov tshuaj tua hluav taws, piv txwv li, tshuaj ua npuas ncauj lossis hmoov.
Txoj hau kev tseem ceeb ntawm kev tua hluav taws kuj suav nrog cov tshuaj lom neeg thiab kev siv tshuabKev tshem tawm hluav taws, uas txhais tau hais tias qhov inhibition ntawm ib qho nyuaj ntawm redox cov tshuaj tiv thaiv, nrog rau kev tshem tawm ncaj qha nrog lub dav hlau dej los yog roj nyob rau hauv siab.
Kev tua hluav taws tau ua tiav nrog kev sib koom ua ke ntawm kev tua hluav taws (dej thiab dej vapor, xuab zeb, ua npuas ncauj, hluav taws tua hluav taws sib xyaw, nrog rau cov ntaub uas tiv taus cov teebmeem no) thiab cov txheej txheem (cranes, hydrants, hoses, twj, thiab lwm yam)..
Kev xaiv ntawm kev siv cov tshuaj tua hluav taws yog nyob ntawm hom, xwm thiab qhov tsis zoo ntawm cov hluav taws, lub xeev ntawm ib puag ncig thiab cov khoom sib sau ua ke, kev ua haujlwm thiab kev ua haujlwm ntawm cov hluav taws tua hluav taws.
Technical txhais tau tias siv los tua hluav taws suav nrog cov hydrants. Cov no yog cov cuab yeej siv los nqa dej los ntawm cov dej xa dej. Hluav taws kub hydrants yog ib qho khoom siv tiav uas muaj cov kav dej, lub valve, lub hose thiab lub thoob. Muaj ntau yam yuav tsum tau khaws cia lub tshuab tua hluav taws no kom nws ua haujlwm.
Kev tshem tawm cov hluav taws kub nruab nrab tuaj yeem ua tau nrog kev pab los ntawm cov txheej txheem ntawm kev tua hluav taws, uas ib txwm muaj xws li cov tua hluav taws ntawm ntau yam qauv, nrog rau cov cuab yeej hluav taws xob thiab khoom siv. Cov hluav taws tua hluav taws raug cais raws li hom kev tua hluav taws. Muaj roj, ua npuas ncauj thiab hmoov.
Kev tua hluav taws nrog cov hluav taws tua hluav taws yog ua los ntawm kev siv cov pa roj carbon dioxide, uas yog tsim nyog los tua cov khoom thiab cov kua. Nyob rau hauv lem, ua npuas ncaujCov hluav taws tua hluav taws yog siv los tshem tawm cov hluav taws kub nyhiab ntawm cov kua thiab cov khoom siv. Qhov tsis zoo ntawm cov tshuaj tua hluav taws zoo li no yog txwv tsis pub siv los tua cov khoom siv, kev sib cuam tshuam nrog uas tuaj yeem ua rau tawg. Piv txwv li, lawv tsis tuaj yeem tshem tawm qhov hluav taws kub ntawm cov khoom siv hluav taws xob uas muaj zog. Hmoov hluav taws tua hluav taws tau pom daim ntawv thov rau cov khoom ntawm txhua lub xeev. Qhov tseem ceeb, lawv tuaj yeem siv los tua hluav taws xob txuas mus txog 1000 V, uas muaj zog.

Hluav taws ua rau muaj kev phom sij ntau ntxiv rau lub ecosystem tag nrho thiab rau txhua yam kab mob nyob hauv nws. Tam sim no, muaj ntau hom hluav taws kub tswj tsis tau. Piv txwv li, txiv neej tsim, teb, hav zoov, peat, steppe hluav taws, nyob rau hauv lub tsev thiab nyob rau hauv ntau yam tsheb
Cov ntaub ntawv xav tau: lub tswv yim, hom thiab cov npe ntawm cov kev xav tau yooj yim
Kev xav tau rau cov ntaub ntawv thiab cov ntaub ntawv muaj qee qhov sib txawv, vim qhov tseeb tias cov ntsiab lus no, txawm tias ze rau lub ntsiab lus, tsis zoo ib yam. Cov ntaub ntawv yog ib daim ntawv teev cov ntaub ntawv, cov lus qhia, cov ntsiab lus thiab qhov tseeb uas tuaj yeem txheeb xyuas, ua tiav thiab rov qab siv dua
Qhov txawv ntawm cov nyiaj tau los thiab cov nyiaj tau los yog dab tsi? Dab tsi yog qhov txawv ntawm cov nyiaj tau los thiab cov nyiaj tau los, lawv cov yam ntxwv
Thaum pom thawj zaug, cov no yog tib lub tswv yim nyiaj tau los, txhais tau tias tau txais cov nyiaj, tab sis cov nyiaj tau los tsis yog cov nyiaj tau los, thiab cov nyiaj tau los tsawg dua cov nyiaj tau los. Tej zaum peb yuav tsum ua raws li cov kev lag luam no, nkag siab txog lawv qhov zoo sib xws thiab qhov sib txawv kom hais lus tib yam nrog cov kws lag luam nyiaj txiag

Txawm hais tias kev ua tsov ua rog tsis yog ib yam li tam sim no, nws tseem tuaj yeem khob qhov rooj. Yog li ntawd, kev npaj rau nws tseem cuam tshuam. Qhov no txhais li cas? Ua ntej tshaj plaws, lawv tham txog kev cob qhia lub cev thiab kev tua, kev muaj peev xwm tsav tsheb, kov yeej cov teeb meem, thiab cov lus txib. Tab sis, dhau li ntawm qhov no, muaj ntau lub ntsiab lus tseem ceeb, tsis muaj qhov nyuaj ua. Tab sis lawv tseem tseem ceeb heev
