Dab tsi yog kev tshawb fawb tom qab lub ntsuas kub infrared?
Hauv qhov xwm txheej, txhua qhov kev txav siab siab tshaj qhov xoom (-273 degree C) muaj nyob rau hauv kev txav ntawm molecular thiab atomic irregularities. Hauv cov txheej txheem no, cov khoom siv tas li tso hluav taws xob hluav taws xob tawm sab nraud. Qhov luaj li cas ntawm lub zog hluav taws xob yog ze ze rau qhov kub ntawm qhov chaw ntawm qhov khoom. Piv txwv li: qhov kub ntawm tib neeg lub cev yog nyob nruab nrab ntawm 36 thiab 37 ° C, thiab lub zog hluav taws xob yog infrared nrog lub wavelength ntawm 9 ~ 13 μm. Lub hauv paus ntsiab lus ntsuas kub ntawm infrared tus pas ntsuas kub yog txhawm rau txheeb xyuas qhov infrared wavelengths ntawm qhov tshwj xeeb ntawm tib neeg lub cev thiab hloov mus rau qhov ntsuas kub los ntawm kev siv hluav taws xob.
Cov ntsuas kub infrared sib txawv, qhov sib txawv loj tshaj plaws tsis yog lub hauv paus ntsiab lus ntawm kev ntsuas kub, tab sis nrhiav cov txheej txheem ntawm cov khoom tshwj xeeb. Muaj kev qhia tsis siv neeg, feem ntau yog siv rau hauv qhov chaw nrog cov neeg loj; muaj cov neeg uas muaj peev xwm "manually aim" los ntawm qhov deb, thiab feem ntau ntawm lawv tuaj yeem tso lub teeb liab me ntsis rau taw ntawm qhov ntsuas kub; tseem muaj cov neeg uas yuav tsum ntsuas lub taub hau ntsuas mus rau qhov ntsuas. Yog li yuav ua li cas siv phau ntawv qhia kev siv kom raug.
Kev siv cov ntsuas kub infrared
- Ua ntej siv thawj zaug, nco ntsoov nyeem cov khoom siv phau ntawv kom nkag siab txog kev siv, kev ceev faj thiab kev saib xyuas.
- Xyuas seb lub roj teeb ntawm tus pas ntsuas kub puas txaus. Rau rechargeable thermometers, xyuas kom tseeb tias nws tau them tag nrho.
- Muab tus pas ntsuas kub tso rau hauv qhov ntsuas qhov ntsuas tsawg kawg 15 mus rau 20 feeb kom hloov mus rau qhov kub ntawm qhov chaw tam sim no.
- Siv lub pob kws kho mob cawv kom maj mam so lub taub hau kom paub tseeb tias tsis muaj stain, thiab tom qab ntawd tos kom dej cawv kom tag nrho ua ntej ntsuas.
- Thaum ntsuas, cia li tuav tus kov ntawm tus ntsuas kub infrared, tom qab ntawd 3-5 cm deb ntawm qhov yuav tsum ntsuas (xws li hauv pliaj, caj npab), thiab tom qab ntawd nias lub pob nrog koj tus ntiv tes.
