Cov hluav taws xob infrared ua rau cov kev sib txuas ntawm cov molecules txav mus los, tso lub zog uas xav tias muaj cua sovTxhua yam khoom siv niaj hnub tso tawm thermal zog-txawm tias cov dej khov nab kuab! Qhov kub tshaj qhov khoom yog, lub zog thermal ntau nws tawm. Lub zog tawm los ntawm ib qho khoom raug xa mus rau qhov khoom siv thermal lossis kub kos npe.
Puas infrared ua mob rau lub cev?
IR raug mob thermal tuaj yeem muaj qhov tseem ceeb biological teebmeem ntawm tib neeg daim tawv nqaij. IR-A rays induce dawb radicals nyob rau hauv lub dermis thiab txo cov tawv nqaij lub peev xwm antioxidant, lub ntsiab ua rau cov tawv nqaij laus ntxov ntxov. Ob leeg ntawm daim tawv nqaij thiab lub pob ntseg yog opaque rau wavelengths >1, 400 nm.
Lub teeb infrared cuam tshuam rau tib neeg li cas?
Kev tshawb fawb kho mob qhia tau tias qhov ntev ntawm IR tuaj yeem ua rau lens, cornea thiab retina puas, suav nrog cov kab mob cataracts, corneal ulcers thiab retinal burns, feem. Txhawm rau pab tiv thaiv kev raug IR mus ntev, cov neeg ua haujlwm tuaj yeem hnav cov khoom siv nrog IR lim lossis cov coatings reflective.
Puas infrared pom ntawm phab ntsa?
Tsis yog, lub koob yees duab thermal tsis tuaj yeem pom ntawm phab ntsa, yam tsawg kawg tsis zoo li hauv cov yeeb yaj kiab. Phab ntsa feem ntau yog tuab txaus-thiab insulated txaus-los thaiv cov hluav taws xob infrared los ntawm lwm sab.
Yuav mus deb npaum li cas infrared?
Infrared hluav taws xob txuas ntxiv los ntawm lub npe liab ntug ntawm qhov pom spectrum ntawm 700 nanometers (nm) txog 1 millimeter (mm) Qhov ntau ntawm wavelengths sib haum rau ntau zaus ntawm kwv yees 430 THz mus rau 300 GHz. Tshaj li infrared yog qhov microwave feem ntawm electromagnetic spectrum.
