Radiation vs Irradiation
Radiation thiab irradiation yog ob txheej txheem sib tham hauv physics thiab lwm yam kev kawm. Radiation yog ib qho txheej txheem uas qee lub zog tau tawg los ntawm ib qho chaw. Irradiation yog txheej txheem uas lub zog hluav taws xob yog qhov tshwm sim ntawm ib qho chaw. Cov ntsiab lus ntawm hluav taws xob thiab irradiation yog ib qho tseem ceeb heev nyob rau hauv cov teb xws li physics, tsis thiab vibrations, quantum mechanics, electromagnetic teb txoj kev xav thiab ntau yam hauj lwm. Hauv tsab xov xwm no, peb yuav tham txog dab tsi hluav taws xob thiab irradiation yog, lawv cov ntawv thov, cov ntsiab lus ntawm hluav taws xob thiab irradiation, qhov zoo sib xws thiab thaum kawg qhov sib txawv ntawm hluav taws xob thiab irradiation.
Radiation
Radiation yog txheej txheem uas lub zog tawm ntawm qhov chaw. Lub zog tuaj yeem tso tawm los ntawm qhov chaw hauv peb txoj kev. Cov txheej txheem ntawm emitting zog los ntawm ib tug nto yog convection, conduction thiab hluav taws xob. Cov txheej txheem ntawm hluav taws xob tsis tas yuav muaj qhov nruab nrab los hloov cov cua sov thiab lub zog. Radiation feem ntau muab faib ua ob hom. Cov no yog hluav taws xob electromagnetic thiab thermal tawg. Cov khoom ntawm ob hom hluav taws xob no zoo sib xws. Tsuas yog qhov sib txawv ntawm ob hom hluav taws xob no yog cov txheej txheem uas lawv tsim. Cov hluav taws xob hluav taws xob yog tsim los ntawm qhov chaw thermal thaum hluav taws xob hluav taws xob yog tsim los ntawm kev oscillation ntawm lub teb hluav taws xob thiab ib qho chaw sib nqus. Lub zog emissions los ntawm hluav taws xob yog quantized. Qhov no yog hu ua quantum nyhuv ntawm hluav taws xob. Ib pob ntawv ntawm lub zog no hu ua photon. Lub zog ntawm photon no tsuas yog nyob ntawm qhov zaus ntawm cov hluav taws xob.
Wien txoj cai kuj yog ib txoj cai tseem ceeb heev hauv thermal tawg. Wien txoj cai lij choj hais tias qhov kub ntawm lub cev dub txiav txim siab lub wavelength uas nws tso tawm ntau tshaj plaws ntawm photons.
Irradiation
Irradiation yog txheej txheem ntawm hluav taws xob poob rau ntawm qhov chaw. Irradiation yog qhov tshwm sim tseem ceeb heev uas tau tham hauv physics. Irradiation tseem ceeb heev nyob rau hauv phenomena xws li cov nyhuv photoelectric, Compton nyhuv, Raleigh scattering thiab ntau yam txheej xwm. Thaum cov nplaim yog irradiated nrog hluav taws xob, cov hluav taws xob yog absorbed los yog reflected. Tus nqi ntawm absorbance los yog qhov reflectance los ntawm ib qho chaw nyob ntawm qhov nqus los yog qhov cuam tshuam ntawm qhov chaw. Lub cev dub nqus tag nrho cov hluav taws xob uas yog irradiated ntawm qhov chaw. Yog li ntawd, lub absorptivity coefficient ntawm lub cev dub yog sib npaug rau ib. Lub absorptivity coefficient thiab lub reflectivity coefficient sib txawv ntawm 0 thiab 1. Qhov ntau ntawm absorptivity coefficient + lub reflectivity coefficient yog sib npaug rau 1, rau txhua qhov chaw.
Dab tsi yog qhov txawv ntawm Radiation thiab Irradiation?
• Radiation yog ib lub npe siv los piav txog ib pawg ntawm photons tawm los ntawm ib qho chaw. Radiation kuj yog siv los ua ib qho lus qhia, los piav txog cov txheej txheem ntawm kev tsim cov photons. Irradiation tsuas yog siv los ua cov lus qhia los piav txog cov txheej txheem ntawm hluav taws xob poob rau ntawm qhov chaw.
• Radiation tuaj yeem tsim los ntawm cov txheej txheem electromagnetic thiab los ntawm tshav kub, thiab.
• Radiation ntawm lub zog los ntawm lub cev ib txwm txo cov zog hauv lub cev. Irradiation ntawm lub cev ib txwm ua kom muaj zog hauv lub cev.
