Kev nrawm yuav tsum ua tau raws li peb yam mob nyob rau tib lub sijhawm: cov khoom siv hluav taws xob, cov khoom siv tiv thaiv kev sib tua thiab cov khoom hluav taws Tso tawm qhov hluav taws kub yog los rhuav tshem cov xwm txheej kub hnyiab uas twb muaj lawm. Ntev npaum li ib qho kev raug mob tuaj yeem tshem tawm, hluav taws tuaj yeem tua hluav taws. Tib neeg tau sau luv luv cov hauv qab no hauv kev coj ua hluav taws kev xyaum.
1. Txias
Txau cov tshuaj tua hluav taws kub ncaj qha rau ntawm cov khoom siv hluav taws xob txhawm rau txo qhov kub ntawm cov khoom sib txuas hauv qab ntawm qhov chaw tiv thaiv tus kheej, yog li tso tseg cov khoom sib txuas, kev tiv thaiv kev ua kom txias ntawm qhov tsis kub ntawm cov khoom sib txuas nrog dej kom tiv thaiv nws kom ncav cuag qhov chaw tiv thaiv thiab txais hluav taws.
Siv dej tua hluav taws kom tua hluav taws. Nws lub luag haujlwm tseem ceeb yog ua kom txias thiab tua hluav taws. Yog tias hluav taws kub tshwm sim, dej tuaj yeem siv los txias thiab tua hluav taws.
2. Kev Txom Nyem
Cov tshuaj sib kis tsis tuaj yeem hlawv thaum tsis muaj cua lossis cov pa oxygen nyob hauv huab cua hauv qab 14%. Qhov txheej txheem ua kom tsis haum pa yog txiav tawm cov pa cua ntawm cov khoom hlawv.
Siv cov kev ntsuas tsim nyog los tiv thaiv huab cua nkag mus rau qhov chaw sib txuas, lossis zom cov ntsiab lus oxygen hauv cov huab cua nrog cov roj inert, kom cov khoom hlawv tsis txaus lossis txiav tawm oxygen thiab tawm mus. Nws yog qhov tsim nyog rau kev tua hluav taws hauv qhov chaw uas tau ntim, cov khoom tsim tawm thiab cov thawv ntim. Thaum siv cov txheej txheem ua tsis taus pa los tawm tsam qhov hluav taws kub ntawm qhov chaw tua hluav taws, siv cov ntaub plua plav, cov hnab ntim dej ntub, cov ntaub ntub dej, cov xuab zeb, ua npuas dej thiab lwm cov ntaub ntawv tsis sib txuas lossis cov khoom tsis txaus los npog lub qhov hlawv lossis kaw lub qhov, sau nrog dej vaum, chaw siv roj av (xws li carbon dioxide, nitrogen, thiab lwm yam) Thaj chaw sib xyaw, siv lub qhov rooj qub ntawm lub tsev thiab qhov chaw ntawm cov khoom siv, chaw cia khoom thiab tsheb thauj mus los kaw qhov chaw sib txuas kom tiv thaiv huab cua nkag.
3. Kev rho tawm
Cov khoom sib txuas yog ib qho ntawm cov teeb meem tseem ceeb tshaj plaws nyob rau hauv kev zawv plaub hau. Yog hais tias cov nplaim hluav taws teeb meem cais tawm los ntawm qhov chaw khaus lossis huab cua, qhov kev tawm tsam kev sib txuas yuav nres. Piv txwv li, cov txheej txheem tshuaj txau hluav taws tua tus neeg tua hluav taws kom cais tawm cov khoom sib cais los ntawm huab cua thiab cua sov, siv cov nplaim hluav taws kub tus neeg sawv cev los npog cov nplaim roj lossis cov khoom ua tau zoo, thiab sib cais sib cais los ntawm nplaim taws thiab huab cua yog txhua qhov kev sib tua hluav taws.
Muaj ntau yam kev ntsuas tshwj xeeb los cais tawm thiab tua hluav taws. Piv txwv li, hloov cov khoom siv hluav taws thiab cov khoom tawg nyob ze qhov chaw tua hluav taws mus rau qhov chaw zoo; kaw lub qhov dej ntawm cov cuab yeej lossis cov kav xa dej kom tiv thaiv cov roj thiab kua los ntawm kev ntws mus rau hauv qhov chaw sib txuas, rhuav tshem cov tsev hluav taws kub uas nyob ib sab ntawm cov hluav taws kom tiv thaiv kev sib kis ntawm thaj chaw hluav taws thiab lwm yam.
4. Kev Tiv Thaiv
Tso cov tshuaj tua hluav taws tso rau tus neeg sawv cev mus rau hauv qhov chaw sib txuas kom koom nrog cov tshuaj tiv thaiv kev sib txuas, yog li cov saw hlau ntawm cov dawb radicals (cov saw hlau txuas) tau nres, kom qhov tshuaj tiv thaiv kev sib tsoo nres lossis tsis txuas ntxiv. Cov tshuaj tua hluav taws uas siv tau rau hauv txoj kev no yog cov hmoov qhuav thiab halogenated alkane hluav taws tua hluav taws. Thaum tua cov hluav taws, qhov tsim nyog ntawm cov neeg tua hluav taws yuav tsum tau muab qhov tseeb rau hauv qhov chaw zuag kom tiv thaiv tus neeg sawv cev tiv thaiv kom tsis txhob thaiv cov tshuaj tiv thaiv kev sib txuas. Nyob rau tib lub sijhawm, ntsuas cua txias yuav tsum tiv thaiv kom tsis txhob rov ua haujlwm.
