Basic txoj kev xav ntawm tshav kub hloov ntawm deb infrared cua sov phaj

1. Cov khoom uas muaj cov yam ntxwv sib txawv emit txawv infrared yam ntxwv (wavelength), cov yam ntxwv sib txawv ntawm cov infrared yog ib qho yooj yim kom tau txais tib yam ntxwv ntawm cov khoom - uas yog, lub infrared emissions los ntawm cov khoom yog yooj yim absorbed los ntawm cov khoom, tsis yooj yim rau cov khoom. yuav absorbed los ntawm cov pa.

2. Cov ntaub ntawv hloov hluav taws xob: hluav taws xob, conduction, convection.

3. Thaum tshav kub kub lub zog yog feem ntau (90 feem pua) kis nyob rau hauv daim ntawv ntawm hluav taws xob nyob rau hauv high kub, thiab nws cov hluav taws xob siv hluav taws xob yog ncaj qha proportional rau plaub lub zog ntawm kub.

4. Lub peev xwm nqus tau ntawm lub zog hluav taws xob hluav taws xob yog proportional rau lub ntsej muag blackness ntawm cov khoom rhuab.

5. Lub tshav kub conduction siv ntawm lub cev rhuab yog ncaj qha proportional rau qhov kub thiab txias gradient (nyob rau saum npoo thiab sab hauv) thiab inversely proportional rau lub thermal kuj.
