Thaum twg infrared hluav taws xob hits ib yam khoom ib co ntawm lub zog yog absorbed, ua rau cov khoom kub nce, thiab ib co yog reflected. Tsaus, mat nto yog zoo absorbers thiab emitters ntawm infrared hluav taws xob . Lub teeb, ci nto yog cov tsis zoo absorbers thiab emitters ntawm infrared hluav taws xob.
Ib yam li ntawd, cov ntaub ntawv dab tsi tuaj yeem cuam tshuam cov hluav taws xob infrared?
Iav, Plexiglas, ntoo, cib, pob zeb, asphalt thiab ntawv tag nrho nqus IR hluav taws xob. Thaum tsis tu ncua nyiaj -Cov iav tsom iav pom pom lub teeb pom kev, tso cai rau koj pom koj qhov kev xav, lawv nqus cov hluav taws xob infrared. Kub, manganese thiab tooj liab kuj nqus IR hluav taws xob zoo.
Ib yam li ntawd, vim li cas cov khoom emit infrared tawg? Infrared tuaj yeem siv los ua ib txoj hauv kev los ntsuas cov cua sov radiated los ntawm ib qho khoom . Qhov no yog qhov hluav taws xob tsim los ntawm kev txav ntawm atoms thiab molecules hauv ib khoom . Qhov kub thiab txias, qhov ntau atoms thiab molecules txav thiab ntau dua infrared lawv tsim.
Tsis tas li ntawd, tib neeg lub cev puas tawm hluav taws xob infrared?
Yog lawm, tib neeg muab tawm hluav taws xob . Tib neeg muab tawm feem ntau infrared hluav taws xob , uas yog electromagnetic hluav taws xob nrog lub zaus qis dua qhov pom lub teeb. Thiab vim hais tias qhov kub ntawm qhov tseeb xoom yog lub cev tsis tuaj yeem, txhua yam khoom muab tawm thermal hluav taws xob.
Yam dab tsi cuam tshuam rau emission thiab nqus cov hluav taws xob infrared?
- Xim thiab kev ntxhib los mos ntawm qhov chaw. Npub, qhov chaw dub yog qhov zoo dua absorbers thiab emitters ntawm infrared hluav taws xob tshaj ci, dawb nto.
- Qhov kub thiab txias. Qhov siab dua qhov kub ntawm qhov chaw ntawm cov khoom txheeb ze rau qhov ntsuas kub ib puag ncig, qhov siab dua ntawm cov hluav taws xob infrared.
- Qhov chaw saum npoo.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Dab tsi yog qhov piv txwv ntawm hluav taws xob hluav taws xob?
Tsis yog piv txwv - hluav taws xob mus los ntawm lub tshuab hluav taws xob mus rau qhov hluav taws xob. Kev hloov hluav taws xob - kev txav ntawm lub zog uas lub zog tsis hloov daim ntawv. Piv txwv li - hluav taws xob mus los ntawm lub tuam txhab hluav taws xob mus rau qhov hluav taws xob. Tsis yog piv txwv – tshuaj zog los ntawm zaub mov hloov mus rau txhua yam
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov txawv ntawm tus kws tshaj lij hluav taws xob thiab tus kws tshaj lij hluav taws xob?
Qhov sib txawv tseem ceeb ntawm cov kws tshaj lij hluav taws xob thiab cov kws tshaj lij xov tooj cua yog lawv cov qib kev kawm.Lawv yuav tau dhau ob qho kev xeem ntawv pov thawj RN thiab theradiology cov kws saib xyuas neeg mob daim ntawv pov thawj xws li ib tus tswj hwm los ntawm Lub Koom Haum rau Radiologic & ImagingNursing
