Tus pas ntsuas kub infrared yuav tsum raug xaiv kom raug
Kev ntsuas kub infrared thev naus laus zis tau ua lub luag haujlwm tseem ceeb hauv kev tswj cov khoom zoo thiab kev saib xyuas, cov cuab yeej siv hauv online kuaj xyuas qhov txhaum, kev tiv thaiv kev nyab xeeb, thiab kev txuag hluav taws xob hauv Suav teb. Hauv ob xyoos dhau los, cov ntsuas kub tsis sib cuag infrared tau tsim sai hauv kev siv thev naus laus zis, txuas ntxiv txhim kho kev ua tau zoo, nthuav dav hauv kev siv tau, thiab nce hauv kev lag luam sib koom txhua xyoo. Piv nrog rau kev ntsuas qhov kub thiab txias, kev ntsuas kub infrared muaj qhov zoo xws li lub sijhawm teb ceev, tsis sib cuag, siv ntev thiab kev pabcuam lub neej. Lub ntsuas suab nrov digital kuj tseem ua lub luag haujlwm hauv kev ntsuas suab qib.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tus pas ntsuas kub sab nraud:
Nkag siab txog kev ua haujlwm, kev qhia tshwj xeeb, ib puag ncig kev ua haujlwm, kev ua haujlwm thiab kev saib xyuas ntawm cov ntsuas kub sab nraud yog los pab cov neeg siv xaiv thiab siv cov ntsuas kub infrared kom raug.
Txhua yam khoom uas muaj qhov kub thiab txias saum toj no * xoom yog tas li emitting infrared hluav taws xob hluav taws xob mus rau qhov chaw nyob ib puag ncig. Cov yam ntxwv ntawm cov hluav taws xob infrared ntawm ib yam khoom muaj feem cuam tshuam nrog qhov loj thiab qhov sib txawv ntawm lub zog hluav taws xob, nrog rau nws qhov kub thiab txias. Yog li ntawd, los ntawm kev ntsuas lub zog infrared tawm los ntawm ib qho khoom nws tus kheej, nws qhov kub thiab txias tuaj yeem ntsuas qhov tseeb, uas yog lub hom phiaj rau kev ntsuas kub ntawm infrared.
Thermometer blackbody hluav taws xob txoj cai:
Blackbody yog lub tshuab hluav taws xob zoo tshaj plaws uas nqus cov hluav taws xob hluav taws xob ntawm tag nrho cov wavelengths yam tsis muaj kev xav lossis kev xa tawm ntawm lub zog. Nws qhov emissivity saum npoo yog 1. Nws yuav tsum tau taw qhia tias tsis muaj lub cev dub tiag tiag hauv qhov xwm txheej, tab sis txhawm rau nkag siab thiab tau txais txoj cai faib tawm ntawm cov hluav taws xob hluav taws xob, nws yuav tsum xaiv cov qauv tsim nyog hauv kev tshawb fawb theoretical. Qhov no yog qhov quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob tau npaj los ntawm Jintai Science Instrument, uas muab txoj cai ntawm blackbody hluav taws xob ntawm Jintai Science Instrument, uas yog, spectral radiance ntawm blackbody qhia nyob rau hauv wavelength. Qhov no yog qhov pib ntawm tag nrho infrared radiation theories, yog li nws yog hu ua blackbody radiation law.
Kev cuam tshuam ntawm emissivity ntawm cov khoom siv ntsuas kub ntawm qhov ntsuas hluav taws xob ntsuas kub:
Yuav luag txhua yam khoom tiag tiag uas muaj nyob hauv qhov tsis yog lub cev dub. Tus nqi hluav taws xob ntawm tag nrho cov khoom tiag tiag tsis yog nyob ntawm lub wavelength ntawm cov hluav taws xob thiab qhov kub thiab txias ntawm cov khoom, tab sis kuj yog nyob ntawm cov khoom xws li hom khoom, kev npaj, txheej txheem thermal, deg lub xeev, thiab ib puag ncig tej yam kev mob uas ua rau cov khoom siv. khoom. Yog li ntawd, txhawm rau txhawm rau txoj cai lij choj ntawm lub cev hluav taws xob siv rau txhua yam khoom siv, nws yog ib qho tsim nyog yuav tsum ua kom paub qhov sib npaug ntawm cov khoom sib txuas nrog rau cov khoom siv thiab lub xeev saum npoo, uas yog emissivity. Qhov coefficient no sawv cev rau qhov sib thooj ntawm cov hluav taws xob hluav taws xob ntawm cov khoom siv tiag tiag thiab cov hluav taws xob lub cev dub, nrog tus nqi ntawm xoom thiab tus nqi tsawg dua 1. Raws li txoj cai ntawm hluav taws xob, tsuav yog qhov emissivity ntawm ib yam khoom paub, lub infrared. hluav taws xob yam ntxwv ntawm tej yam khoom yog paub.
