Qhia luv luv ntawmUltraviolet phototube:

Ultraviolet phototube yog hom ntawm ultraviolet nrhiav lub raj nrog cov nyhuv photherelectric. Cov photocell siv cov cathode los tsim cov duab duab, thiab ionization tshwm sim vim kev sib tsoo hauv lub raj hauv lub raj thaum lub sijhawm ionization; Cov tshuab hluav taws xob tshiab thiab cov photoelectrons tsim los ntawm cov txheej txheem ionization yog ob qho tib si tau txais los ntawm anode, thaum zoo ionsde, thaum lub ntsej muag zoo tau txais los ntawm cathode hauv kev coj rov qab. Yog li ntawd, lub photocrrent nyob rau hauv anode Circuit Court yog ob peb npaug loj dua li ntawd hauv lub tshuab nqus tsev. Ultraviolet photocells nrog hlau photovoltaic thiab roj ntau zaus tuaj yeem tshawb xyuas cov ultraviolet hluav taws xob hauv ntau yam ntawm 185-300mm thiab tsim cov ntaub ntawv.

Nws yog qhov tsis txaus ntseeg rau hluav taws xob sab nraum cheeb tsam spectral cheeb tsam no, xws li pom kev tshav ntuj thiab sab hauv teeb pom kev zoo. Yog li nws tsis tsim nyog siv lub teeb pom kev ntawm cov ntaub thaiv npog raws li lwm cov khoom siv sliconduct, yog li nws yooj yim dua rau kev siv.
Ultraviolet phototube tuaj yeem pom tsis muaj zog ultraviolet hluav taws xob. Nws tuaj yeem siv rau hauv boiler roj roj, roj xyuas, hluav taws kub, hluav taws xob tiv thaiv kev tiv thaiv kev saib xyuas ntawm cov chaw tsis muaj kev saib xyuas, thiab lwm yam.
