Kev taw qhia luv luv ntawmLub raj duab ultraviolet:

Lub raj xa duab ultraviolet yog ib hom raj xa duab ultraviolet uas muaj cov nyhuv photoelectric. Hom photocell no siv cathode los tsim cov duab photoemission, cov duab electrons txav mus rau anode nyob rau hauv qhov kev ua ntawm lub zog hluav taws xob, thiab ionization tshwm sim vim kev sib tsoo nrog cov pa roj hauv lub raj thaum lub sijhawm ionization; cov electrons tshiab thiab cov duab electrons tsim los ntawm cov txheej txheem ionization ob leeg tau txais los ntawm anode, thaum cov ions zoo tau txais los ntawm cathode hauv qhov kev taw qhia rov qab. Yog li ntawd, cov duab tam sim no hauv lub voj voog anode yog ntau zaus loj dua li hauv lub raj xa duab nqus tsev. Cov duab ultraviolet nrog cov hlau photovoltaic thiab cov roj sib npaug tuaj yeem ntes cov hluav taws xob ultraviolet hauv qhov ntau ntawm 185-300 hli thiab tsim cov duab tam sim no.

Nws tsis muaj zog rau cov hluav taws xob sab nraud thaj chaw spectral no, xws li lub hnub ci pom thiab cov teeb pom kev hauv tsev. Yog li nws tsis tas yuav siv lub teeb pom kev zoo li lwm cov khoom siv semiconductor, yog li nws yooj yim dua rau siv.
Lub raj xa duab ultraviolet tuaj yeem ntes tau cov hluav taws xob ultraviolet tsis muaj zog. Nws tuaj yeem siv rau hauv roj boiler, kev saib xyuas roj, lub tswb hluav taws, lub zog hluav taws xob rau kev saib xyuas kev tiv thaiv xob laim ntawm lub transformer tsis muaj neeg saib xyuas, thiab lwm yam.
