Cov khoom no yog dab tsi?
Krypton yog ib qho ntawm 6 lub suab nrov nrov, uas yog cov ntsiab lus uas muaj cov yam ntxwv ntawm lawv qhov tsis tshua muaj zog, cov ntsiab lus kub kub, thiab tag nrho cov hluav taws xob sab nraud. Krypton tsis muaj xim, tsis muaj ntxhiab, thiab tsis qab. Nws yog denser tshaj huab cua thiab muaj ib tug ntau dua melting thiab boiling point tshaj lighter noble gases. Nws yog ib qho inert thiab tsis nkag siab nrog lwm cov ntsiab lus. Raws li ib qho tsis tshua muaj roj, Krypton pom nyob rau hauv cov lej hauv lub ntiaj teb huab cua thiab tau muab rho tawm los ntawm cov txheej txheem ntawm fractional distillation ntawm cov kua cua.
Qhov twg siv cov khoom no?
Teeb pom kev zoo: Krypton feem ntau yog siv nyob rau hauv high-intensity discharge (HID) teeb, tshwj xeeb tshaj yog nyob rau hauv automotive headlights thiab tshav dav hlau khiav teeb pom kev zoo. Cov teeb no tsim lub teeb ci, dawb haum rau kev siv sab nraum zoov.
Laser technology: Krypton yog siv los ua qhov nruab nrab hauv qee hom lasers, xws li krypton ion lasers thiab krypton fluoride lasers. Cov lasers no tau ua haujlwm hauv kev tshawb fawb tshawb fawb, kev siv kho mob, thiab cov txheej txheem kev lag luam.
Kev yees duab: Krypton flash teeb yog siv nyob rau hauv high-speed photography thiab hauv flash units rau kev yees duab.
Spectroscopy: Krypton yog siv rau hauv kev ntsuas ntsuas, xws li huab hwm coj spectrometers thiab roj chromatographs, kom paub tseeb thiab tsom xam ntawm ntau lub tebchaw.
Thermal rwb thaiv tsev: Nyob rau hauv tej yam thermal rwb thaiv tsev ntaub ntawv, xws li rwb thaiv tsev qhov rais, krypton yog siv los ua ib tug filling gas nyob rau hauv lub inter-pane qhov chaw kom txo tau tshav kub thiab ua kom lub zog efficiency.
Nco ntsoov tias cov ntawv thov tshwj xeeb thiab cov cai rau kev siv cov khoom siv / cov khoom no yuav txawv ntawm lub teb chaws, kev lag luam thiab lub hom phiaj. Nco ntsoov ua raws li cov lus qhia kev nyab xeeb thiab sab laj nrog tus kws tshaj lij ua ntej siv cov khoom siv / cov khoom no hauv txhua daim ntawv thov.
