Tej zaum koj yuav ntsib teeb pom kev dub ntawm cov chaw ua si lom zem, tsev cia puav pheej tshawb fawb, thiab cov khoom pov thawj Halloween. Cov teeb dub zoo ib yam li cov teeb fluorescent lossis cov teeb ci, txawm tias lawv ua haujlwm txawv. Ua kom muaj ib qho, thiab cov ris tsho dawb, kho hniav enamel, thiab ob peb lwm yam khoom luminesce hauv qhov tsaus ntuj.
Piv txwv li, illuminating ib daim ntawv fluorescent nrog ib lub teeb dub nyob rau hauv ib chav tsaus nti yuav ua rau cov ntawv tshaj tawm emitting lub ci ntsa iab. Tej zaum koj yuav tau ntsib cov nplooj ntawv uas zoo nkaus li dawb paug nyob rau hauv ib txwm teeb pom kev zoo tab sis nthuav tawm cov lus luminous thaum raug ultraviolet teeb. Ntau qhov chaw ua si lom zem siv cov ntawv luam tawm uas pom tsis pom hauv qab lub teeb ultraviolet.
Nplooj ntawv no yuav qhia txog qhov xwm txheej tam sim no. Peb yuav tshuaj xyuas seb vim li cas lub teeb dub ua rau qee yam khoom fluoresce thaum lwm tus tsis ua, thiab peb yuav tshawb xyuas ntau qhov kev xav ntawm lub teeb dub.
Dab tsi yog "Lub teeb dub"?
Ua kom lub teeb dub nyob rau hauv ib chav tsaus nti ua rau cov ntshav luminescence. Lub teeb ultraviolet emitted los ntawm lub teeb yog imperceptible rau qhov muag liab qab.
Tib neeg lub qhov muag pom lub teeb pom kev hauv ib lub spectrum uas suav nrog liab, txiv kab ntxwv, daj, ntsuab, xiav, thiab violet.Ultraviolet lub teeb, uas yog imperceptible rau tib neeg lub qhov muag, lies dhau lub violet spectrum. Yuav ua li cas Sunburns thiab Sun Tans tshuaj xyuas UV hluav taws xob thiab nws qhov cuam tshuam rau tib neeg daim tawv nqaij. Lub teeb dub dub emits UVA lub teeb, sib piv rau UVB hluav taws xob, uas yog qhov cuam tshuam ntau dua.
Ultraviolet lub teeb frequencies tshaj violet ntawm lub spectrum thiab yog imperceptible rau tib neeg lub qhov muag.
Cov ntsiab lus luminous pom nyob rau hauv lub teeb dub, txawm nyob rau ntawm daim ntawv fluorescent, ib daim ntawv tsis pom kev, lossis ib lub tsho dawb T-, yog phosphors.
phosphor yog ib yam khoom uas emits pom lub teeb thaum raug hluav taws xob. Ib tug phosphor hloov lub zog los ntawm ultraviolet hluav taws xob tawm los ntawm lub teeb dub rau hauv pom lub teeb.
Hauv qhov txuas ntxiv, peb yuav tshuaj xyuas cov ntawv thov ntawm phosphors hauv cov teeb pom kev zoo fluorescent thiab cov teeb dub.
Dab tsi ua rau kuv lub tsho ci ntsa iab?
Dawb T-shirts thiab thom khwm feem ntau fluoresce nyob rau hauv ultraviolet lub teeb vim yog siv phosphors nyob rau hauv niaj hnub detergents uas hloovUV hluav taws xobmus rau hauv lub teeb pom kev dawb. Qhov no ua rau cov nqaij dawb zoo li "dawb dua li dawb" nyob rau hauv ntuj tshav ntuj. Qhov koj tab tom pom nyob rau hauv tshav ntuj yog qhov kev xav ntawm lub teeb pom kev dawb ntawm cov ntaub, nrog rau kev tawm ntawm lub teeb dawb uas cov phosphors tsim los ntawm UV rays nyob rau hauv tshav ntuj. Lub tsho T- yeej yog dawb dua li dawb.
Lub teeb dub muaj nyob rau hauv ob lub raj thiab lub teeb teeb.
Tus qauv teeb pom kev zoo dub tsuas yog lub teeb fluorescent nrog ntau qhov kev hloov pauv tseem ceeb. Cov teeb fluorescent tsim lub teeb los ntawm kev xa hluav taws xob los ntawm lub raj uas muaj cov roj inert thiab tsawg kawg ntawm mercury.
Thaum qhib, mercury atoms emit zog nyob rau hauv daim ntawv ntawm lub teeb photons. Lawv emit ib tug tsawg tus naj npawb ntawm pom lub teeb photons, feem ntau emitting photons nyob rau hauv lubultraviolet(UV) wavelength ntau yam. Lub teeb fluorescent yuav tsum hloov cov teeb ci ultraviolet, uas yog imperceptible rau tib neeg lub qhov muag, mus rau qhov pom kev. Ib txheej phosphor encircles rau sab nraud ntawm lub raj.
Phosphors yog cov khoom siv uas tawm lub teeb, lossis fluoresce, thaum raug teeb pom kev zoo. Raws li qhov cuam tshuam ntawm photon rau ntawm phosphor atom, ib qho hluav taws xob hauv phosphor nce mus rau lub zog siab dua, ua rau muaj kev co atomic thiab tsim hluav taws xob. Thaum rov qab mus rau hauv av, lub electron emits lub zog raws li ib tug photon. Cov photon no muaj lub zog qis dua qhov pib photon vim lub zog poob thaum tshav kub. Lub teeb fluorescent emits lub teeb nyob rau hauv qhov pom kev, raws li phosphor tsim perceivable dawb lub teeb.
Lub teeb dub ua haujlwm ntawm qhov chaw zoo ib yam. Muaj ob hom sib txawv ntawm lub teeb dub, txawm li cas los xij lawv ua haujlwm hauv qhov zoo sib xws.
Lub raj dub lub teeb yog qhov tseem ceeb ntawm lub teeb fluorescent nrog ib hom phosphor txheej. Cov txheej no absorbs cov teeb meem luv luv UV-B thiab UV-C hluav taws xob thaum emittingUV-Ib lub teeb, zoo ib yam li yuav ua li cas phosphor nyob rau hauv lub teeb fluorescent absorbs UV hluav taws xob thiab emits pom lub teeb. Lub raj iav "dub" cuam tshuam rau feem ntau ntawm cov teeb pom kev zoo, tsuas yog tsis muaj teeb meem ntev ntev -yoj UV-Ib hluav taws xob, nrog rau qee qhov xiav thiab violet pom lub teeb, kom permeate.
Lub teeb dub incandescent zoo li lub teeb lub teeb hauv tsev, tshwj tsis yog nws siv lub teeb lim kom nqus tau cov teeb pom kev zoo los ntawm cov cua sov filament. Nws absorbs tag nrho cov wavelengths tshwj tsis yog rau infrared, UV-Ib hluav taws xob, thiab ib feem me me ntawm pom lub teeb.
Nyob rau hauv ob qho tib si lub teeb tsim, lub teeb tsim UV cuam tshuam nrog cov phosphors sab nraud tib yam uas UV teeb nyob rau hauv lub teeb fluorescent cuam tshuam nrog nws cov phosphor txheej. Sab nraud phosphors emit luminescence thaum raug UV hluav taws xob.
Daim ntawv thov ntawmLub teeb dub
Taug kev nyob ib puag ncig txhua hmo nrog lub teeb txawb nqa tau yooj yim yuav nthuav tawm qhov muaj phosphor ubiquitous. Ntau cov phosphors ntuj muaj nyob, suav nrog cov uas pom hauv cov hniav thiab cov rau tes, ntawm lwm yam khoom. Cov ntaub ntawv uas neeg tsim, xws li cov ntxaij vab tshaus TV, qee cov xim, ntaub, thiab cov yas, kuj muaj cov phosphor ntau heev. Ntau yam khoom fluorescent, nrog rau cov ntsiab lus tseem ceeb, suav nrog phosphors, uas tseem muaj nyob rau hauv tag nrho cov ci ntsa iab - hauv - cov khoom tsaus nti. Cov koom haum thiab cov chaw ua si lom zem siv cov xim dub tshwj xeeb uas tawm ntau xim thaum pom kev. Fluorescent dub lub teeb npuas, pom tsis pom lub teeb dub cwj mem, fluorescent dub lub teeb ntaub pua plag, thiab fluorescent dub lub teeb plaub hau gel kuj muaj rau kev yuav khoom.
Standard highlighters ua hauj lwm zoo li "dub lub teeb cwjmem." Lub luminous number case radiates hauv qablub teeb tsaus!
Dhau li ntawm kev txhim kho kev zoo nkauj ntawm cov tib neeg thiab cov ntawv tshaj tawm fluorescent, lub teeb dub muab ntau yam kev siv. Piv txwv li:
Cov neeg soj ntsuam siv lawv los txheeb xyuas cov khoom cuav ntawm cov khoom qub. Cov xim niaj hnub no feem ntau suav nrog phosphors uas tawm luminescence nyob rau hauv ultraviolet lub teeb, tab sis feem ntau cov xim tsis muaj phosphors.
Technicians utilise them to detect imperceptible leaks in machinery by injecting a little amount of fluorescent dye into the fuel supply and illuminating it withultraviolet lub teeb. Piv txwv li, lawv tuaj yeem txheeb xyuas qhov tsis zoo ntawm lub tshuab cua txias los ntawm kev sib xyaw cov xim fluorescent rau hauv cov tub yees. Ultraviolet teeb tuaj yeem ua haujlwm los txheeb xyuas cov txiaj ntsig cuav.
Cov tub ceev xwm tuaj yeem siv lawv los txheeb xyuas cov txiaj ntsig cuav. Tebchaws Asmeskas thiab ntau lub tebchaws suav nrog cov khoom siv hluav taws xob tsis pom zoo hauv lawv cov ntawv sau nyiaj siab dua, uas pom tau tsuas yog nyob rau hauv lub teeb ultraviolet.
Cov chaw ua si lom zem thiab cov koom haum siv lawv kom paub txog cov ntawv luam fluorescent uas tsis tuaj yeem nkag mus rau hauv.
Cov kws tshawb fawb forensic ntiav lawv los tshuaj xyuas qhov xwm txheej ua txhaum cai. Txhawm rau rho tawm cov ntiv tes, lawv nquag siv cov xim fluorescent thiab tshuaj xyuas nws hauv qab lub teeb ultraviolet. Qhov no ua kom yooj yim tshem tawm cov ntiv tes los ntawm cov khib nyiab uas nyob ib sab. Lub teeb dub tuaj yeem ntes cov phev thiab lwm cov kua dej hauv lub cev uas muaj cov fluorescence ntuj.
Ntau ntawm cov ntawv thov no, nrog rau ntau ntxiv, ua raws li lub ntsiab lus tseem ceeb: lub teeb dub ua rau pom tsis pom lossis cais cov tshuaj tshwj xeeb los ntawm nws ib puag ncig. Raws li kev xav, ntau qhov xwm txheej muaj nyob rau hauv uas qhov tshwm sim no tuaj yeem siv tau. Kev siv tau yog txwv tsis pub.
