A fluorescent teeb , los yog cev fluorescent , yog ib qho tsis tshua muaj siab mercury-vapor gas-kua tawm teeb uas siv fluorescence rau tsim tawm pom teeb . Ib qho hluav taws xob tam sim no nyob rau hauv cov pa excites mercury vapor, uas tsim tawm luv-yoj ultraviolet teeb uas ces ua rau ib tug phosphor txheej nyob rau hauv lub teeb mus ci.

Ua kom pom qhov no, vim li cas lub teeb fluorescent dawb?

Cia peb saib ze dua ntawm lub mechanism uas fluorescent teeb emits ultraviolet rays. Electrons tawm ntawm lub electrode sib tsoo nrog cov mercury atoms uas muaj cov vapor hauv lub iav raj. Nws yog txheej txheej no ua rau fluorescent teeb kom ci dawb.

Qhov thib ob, lub teeb fluorescent muab xim dab tsi? Txias dawb fluorescent qhov muag teev muaj qhov nruab nrab mus rau siab xim kub, thiab tsim teeb uas yog dawb dawb los yog dej khov dawb hauv xim . Qhov siab tshaj xim qhov kub thiab txias tsim ib qho txawm bluer teeb , uas suav nrog cov liab thiab txiv kab ntxwv los ntawm qhov kub thiab txias dhau los tab sis ntxiv xiav wavelengths uas tint tag nrho spectrum.

Ua raws li qhov no, qhov teeb pom kev fluorescent siv nyob qhov twg?

Kev siv thiab qhov zoo Fluorescent teeb muab lub teeb los ntawm qhov loj ci ntsa iab es tsis yog qhov chaw me me. Cov no teeb feem ntau siv nyob rau hauv cov xwm txheej uas hu rau kev teeb pom kev dav dav ntawm ib theem xws li chaw ua haujlwm, chav kawm, khw muag khoom, hauv tsev, thiab tsev noj mov.

Puas yog lub teeb fluorescent zoo ib yam li lub hnub ci?

Zoo li hnub ci , fluorescent teeb kuj yog dawb teeb , thiab nws kuj yog tsim los ntawm ntau qhov sib txawv wavelengths. Tab sis, lub wavelengths nyob rau hauv fluorescent teeb tsis raws nraim cov ib yam raws li cov hauv hnub ci.
