Taw qhia rau cov cai thiab cov ntsiab cai ntawm cov ntsuas kub
Kev cai hluav taws xob hluav taws xob ntawm tus pas ntsuas kub online: yog kom muaj cov qauv hluav taws xob, tab sis kom muaj cov qauv kev faib tawm hauv hluav taws xob, thiab kom muaj cov qauv kev sib tw yog 1. Qhov no yog cov Quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob tau npaj los ntawm Dub Mirdians ntawm Blackbody Radiation qhia nyob rau hauv wavelength. Qhov no yog qhov pib ntawm txhua qhov hluav taws xob ntsuas hluav taws xob theoriariation, li no nws yog hu ua Blackbody Browiay txoj cai lij choj.
Tus yam ntxwv ntawm lub cev muaj emissivity ntawm kev ntsuas kub ntsuas: yuav luag txhua cov khoom tiag tiag hauv cov xwm tsis yog blackbodies. Kev ntsuas hluav taws xob ntawm txhua qhov khoom siv hluav taws xob nyob ntawm tsis tsuas yog nyob ntawm cov khoom siv hluav taws xob thiab kub, tab sis kuj tseem muaj cov txheej txheem, thiab ib puag ncig lub xeev, thiab ib puag ncig cov mob uas ua rau cov khoom. Yog li ntawd, txhawm rau ua kom tus Dub Tsis Muaj Peev Xwm Hluav Taws Xob uas muaj feem xyuam nrog cov khoom siv thiab cov xeev tau xwm txheej, yuav tsum tau ua qauv. Qhov no coefficent sawv cev rau cov qib uas lub thermal hluav taws xob ntawm cov khoom siv hluav taws xob zoo nkauj, muaj nuj nqis ntawm cov khoom muaj txiaj ntsig ntawm 1. Lub ntsiab tseem ceeb cuam tshuam nrog kev ua emissivity suav nrog cov khoom siv, nto roughness, lub cev thiab cov ntaub ntawv tuab.
Thaum siv tus pas ntsuas kub infrared los ntsuas qhov kub ntawm lub hom phiaj ntawm lub hom phiaj hauv lub hom phiaj, thiab tom qab ntawd tus pas ntsuas kub ntsuas qhov ntsuas kub ntawm lub hom phiaj ntsuas. Monochromatic Sov Hluav Taws Xob yog sib npaug rau cov hluav taws xob hauv cov band zaus; Cov pas ntsuas kub ob lub pas ntsuas kub yog sib npaug ntawm hluav taws xob hauv ob pawg.
Qhov tsis yog hu rau infrared txhuas txhuas siv thev naus laus zis ntau zaus kom nrawm nrawm thiab ntsuas qhov ntsuas kub. Hom twj paj nruag no tuaj yeem tsim kho qhov kub thiab txias nyeem tsis muaj kov cov khoom. Qhov ntsuas kub tau tshwm sim ntawm LCD npo. Lub teeb yuag, sophisticated, thiab yooj yim-siv infrared thermometers thiab nyuaj rau kev nyab xeeb, lossis nyuaj rau kev nyab xeeb yam tsis muaj kev phom sij lossis ua kom lub hom phiaj ntsuas. Tsis tas li ntawd, cov ntsuas kub tsis muaj peev xwm ua kom muaj ntau ntau kev nyeem ib ob, thaum sib tham nrog cov thermometers yuav siv sijhawm ntau feeb los ntsuas txhua lub sijhawm.
