NIR spectrum originates los ntawm hluav taws xob xa mus rau lub zog siv hluav taws xob cuam tshuam nrog kev txav ntawm atoms tuav ua ke los ntawm cov tshuaj sib txuas hauv cov molecule.
NIR hluav taws xob yog dab tsi?
NIR yog cov lus luv rau Nyob ze InfraRed spectroscopy, thiab nws yog hais txog cov txheej txheem tshuaj xyuas ntawm kev siv hluav taws xob ze-infrared los tshuaj xyuas cov qauv rau cov khoom sib xyaw lossis cov yam ntxwv. NIR kuj tau siv los piav txog Ze-Infrared Reflectance.
Dab tsi yog qhov chaw ntawm hluav taws xob hauv IR spectroscopy?
Infrared qhov chaw muaj ib qho khoom inert uas yog hluav taws xob rhuab mus rau qhov kub ntawm 1, 500 thiab 2, 200 K. Cov khoom rhuab yuav ces emit infrared tawg. Lub Nernst glower yog tsim los ntawm tsawg lub ntiaj teb oxides nyob rau hauv daim ntawv ntawm ib tug hollow cylinder.
Qhov twg siv rau thaj tsam deb infrared?
Qhov kub silicon carbide qhov chaw siv hauv kev lag luam infrared spectrometers, feem ntau hu ua "glow bar," yog txwv rau wavelengths luv dua 100 µm los ntawm λ −2 dependence ntawm kev siv ntawm lub teeb, raws li tau zoo raws li qhov tseeb hais tias nws emissivity poob ntawm ntev wavelengths, txo qhov kev siv tseem ntxiv.
Dab tsi yog qhov tsis zoo ntawm cov hluav taws xob infrared?
Ntev ntev raug rau IR hluav taws xob ua rau maj mam tab sis hloov tsis tau ntawm lub lens. Lwm yam kev puas tsuaj rau lub qhov muaglos ntawm IR raug suav nrog scotoma, uas yog qhov tsis pom kev vim kev puas tsuaj rau lub retina. Txawm tias qis qis IR nqus tuaj yeem ua rau cov tsos mob xws li redness ntawm qhov muag, o, lossis hemorrhaging.

Dab tsi yog qhov txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob?
Gramophone: Txhua lub suab kaw suab, lossis cov cuab yeej ua si yav dhau los-cov suab kaw, tshwj xeeb tshaj yog tias nws siv lub tiaj tiaj tiaj. Phonograph: Txhua lub suab kaw suab, lossis cov cuab yeej siv rau kev ua si cov suab uas tau kaw dhau los, tshwj xeeb tshaj yog tias nws siv lub tog raj kheej tig.
Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Lub tshuab hluav taws xob tsim hluav taws xob nyob qhov twg?
Generac G-FORCE® thiab OHVI cov cav yog tsim thiab tsim los ntawm Generac Power Systems Inc. ntawm peb cov chaw hauv Wisconsin. Cov khoom lag luam Generac nyob qhov twg? Generac yog lub hauv paus hauv Waukesha, Wisconsin, thiab muaj chaw tsim khoom hauv Berlin, Oshkosh, Jefferson, Eagle, thiab Whitewater;
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
