Dab tsi yog qhov ua haujlwm ntawm cov khoom noj khoom haus rwb thaiv tsev
Nyob rau hauv cov ntaub ntawv ntawm tas mus li cua sov ntawm peb cov tais diav, cov kab lus ntawm cov zaub mov nws tus kheej yuav txo tau heev.
Tsis tas li ntawd, cov as-ham hauv cov tais diav yog yooj yim dua. Qhov no yog vim hais tias feem ntau muaj ntau ntau cov as-ham hauv cov zaub mov, ntawm cov dej- cov vitamins soluble, xws li cov vitamins C thiab E, ntshai heev kub.
Cov as-ham ntawm zaub thiab txiv hmab txiv ntoo tsuas yog tshwm sim hauv cov nplua nuj thiab muaj yeeb yuj cov vitamins, yog li cov nqaij rov ua dua tshiab muaj kev puas tsuaj loj rau cov as-ham.
Tsis tas li ntawd, cov ntsev ntawm qhov chaw ntawm cov khoom noj yuav ua rau muaj nitrate, uas yog teeb meem rau nws tus kheej. Thaum nws ntsib cov protein nyob rau hauv lub plab, nws yuav ua rau carcinogen nitrous, uas yuav ua rau kom muaj peev xwm ntawm carcinogens rau txhua leej txhua tus.
Thiab tam sim no txhua leej txhua tus siv cov khoom noj khoom haus rwb thaiv tsev rau tag nrho cov teeb meem ntawm cua sov cov zaub mov tsis tu ncua.
Lub luag haujlwm tseem ceeb ntawm cov khoom noj khoom haus rwb thaiv tsev yog ua kom sov thiab ua kom sov cov zaub mov. Nws tuaj yeem tsim hluav taws xob tsis tu ncua rau cov zaub mov, ua kom cov zaub mov kub thaum pib mus txog thaum xaus, thiab daws qhov txaj muag ntawm cov cua sov thib ob.

Dab tsi yog cov ntsiab lus ntawm thermal rwb thaiv tsev board
Lub hauv paus ntsiab lus ntawm lub rooj noj mov rwb thaiv tsev yog siv cov ntawv hluav taws xob cua sov, hluav taws xob cua sov zaj duab xis thiab lwm yam ntaub ntawv kub los ua kom sov rau cov tswj vaj huam sib luag. Tom qab cov tswj vaj huam sib luag yog rhuab, lub tshav kub hloov mus rau hauv chav ua noj cov tais diav rau cua sov rwb thaiv tsev thiab qhuav lauj kaub tais diav. Qhov no kuj yog ib qho hluav taws xob rwb thaiv tsev ntawm cov plua plav rwb thaiv tsev. Lwm txoj hauv kev txuag hluav taws xob yog siv dej vapor. Txhua leej txhua tus paub tias cov dej vapor nce thiab cov cua txias hauv lub dab dej. Tom qab lub vapor yog rhuab, yog tias qhov zoo tsis hloov tab sis lub ntim nthuav dav, nws tuaj yeem xam raws li cov qauv: txheeb ze ntom ntom=zoo / ntim, thiab cov txheeb ze ntom ntom.
According to Archimedes' principle and the floating and sinking standards of objects, we can understand:
Cov Cheebtsam nrog cov ntom ntom tsawg yuav nce thiab thaum kawg ntab; thaum lub Cheebtsam uas muaj siab ceev yuav txav mus thiab thaum kawg tog.
Nws tuaj yeem nkag siab raws li cov kev paub dhau los saum toj no: cov dej vapor floats, thiab lub tshuab cua txias.
Lub hauv paus cua txias uas txhua tus neeg feem ntau siv feem ntau yog ntsia saum phab ntsa, cia lub tshuab cua txias txav mus, thiab thaum kawg txias tag nrho chav; thiab cov phaj cua sov yuav tsum tau muab tso rau hauv qab phab ntsa, ua rau cov dej vapor ntab tuaj, thiab thaum kawg sov txhua yam. chav.
Qhov no kuj yog lub hauv paus ntsiab lus.
Cov khoom noj khoom haus rwb thaiv tsev siv lub hauv paus ntsiab lus no, siv cov txheej txheem ntawm kev sib kis thiab cov txheej txheem ntawm cov dej vapor encapsulation, kom sov cov zaub mov ntawm cov khoom noj khoom haus rwb thaiv tsev rau qhov kub thiab txias tus nqi teev los ntawm txhua tus neeg, thiab tswj qhov kub ntawm tus nqi yuav tsis hloov.
