Teb: Cov tshuaj tiv thaiv ntawm hlau (III) oxide (Fe203) thiab txhuas ua rau cov cua sov ntau. Nws yog hu ua thermit reaction. Qhov kev tshem tawm cov tshuaj tiv thaiv no yog siv los koom nrog kev tsheb ciav hlau lossis cov tshuab tawg. Lub tshav kub uas muab tawm hauv cov tshuaj tiv thaiv melts hlau tsim.
Koj txhais li cas los ntawm cov tshuaj tiv thaiv thermite?
Cov tshuaj tiv thaiv thermite yog lub npe dav rau ib qho exothermic (heat-tso tawm) cov tshuaj tiv thaiv ntawm ferrous oxides thiab txhuas (feem ntau hauv cov hmoov hmoov). Qhov sib xyaw ntawm txhuas thiab hlau oxide, tseem hu ua thermite, paub txog nws lub peev xwm los tsim cov cua sov thaum combustion.
Cov tshuaj tiv thaiv thermite yog dab tsi yog nws daim ntawv thov chav kawm 10?
Teb: Cov tshuaj tiv thaiv thermite yog cov tshuaj tiv thaiv exothermic ntawm cov hlau thiab hlau oxidePiv txwv li cov tshuaj tiv thaiv ntawm txhuas nrog cov hlau oxides, qhov twg txhuas ua raws li tus neeg sawv cev txo. Cov txhuas txo cov hlau oxide feem ntau yog hlau (lll) oxide los tsim ferrous thiab txhuas oxide.
txheej txheem thermite yog dab tsi qhov twg cov txheej txheem no siv Chav Kawm 10?
Nws tseem yog feem ntau hu ua Goldschmidt thermite txheej txheem lossis aluminothermy. -Cov tshuaj tiv thaiv ua kom muaj cua sov ntau uas txaus kom ncav cuag qhov kub ntawm li 3500oC. Cov hlau yog li tau txais yog nyob rau hauv lub xeev molten. -Cov txheej txheem no yog siv nyob rau hauv vuam ntawm railway lem, hnyav machinery, thiab lwm yam
Cov tshuaj tiv thaiv thermite yog dab tsi sau nws daim ntawv thov?
Kev siv cov txheej txheem thermite: 1) Cov tshuaj tiv thaiv ntawm Iron Oxide (Fe 2 O 3) nrog txhuas yog siv los koom nrog railings ntawm railway lem los yog mus koom lub tshuab tawg. 2) Nws kuj tseem siv tau los koom nrog cov khoom siv hlau tawg hauv tsev.

Dab tsi yog cov tshuaj tiv thaiv catalyzed los ntawm cov enzymes tseem ceeb gluconeogenic?
Plaub qhov tshwj xeeb ntawm gluconeogenesis yog pyruvate carboxylase, nyob hauv mitochondrialmatrix, phosphoenolpyruate (PEP) carboxykinase nyob rau hauv mitochondrial matrix thiab cytosol, fructose-1, 6-bisphosphatase nyob rau hauv cytosol thiab qabzib-6-phosphatase nyob rau hauv endoplasmic reticulum (ER) .
Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Dab tsi yog ob pawg tseem ceeb ntawm cov khoom thiab cov tshuaj tiv thaiv?
Cov tub ntxhais kawm yuav kawm tias cov khoom tuaj yeem raug cais raws li hadrons - baryons thiab mesons- thiab lepton, txhua tus nrog nws cov khoom tiv thaiv, thiab lawv yuav tsum paub tias kev cuam tshuam ntawm cov khoom no tuaj yeem ua tau.
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
