Nws tau siv nyob rau hauv cov ntaub ntawv cathhoe, electron tsom iav pov thawj, hluav taws xob vuam cov ntawv thov hauv cov teb uas xav tau siab emission cov dej khib nyiab, xws li kev ua yeeb yaj.
Linthhanum Hexaborate Hexaboratemuaj cov tshuaj ruaj khov thiab tsis muab tshuaj tiv thaiv nrog dej, oxygen, lossis txawm tias hydrochloric acid; Nyob rau hauv chav tsev kub, nws tsuas yog rov qab nrog nitric acid thiab aqua regia; Oxidation tsuas yog tshwm sim ntawm 600-700 ℃ hauv ib qho chaw aerobic. Nyob rau hauv lub tshuab nqus tsev, LANCT6 cov khoom siv yog qhov ua rau muaj kev cuam tshuam nrog lwm cov tshuaj lossis roj av los ua cov khoom siv tsawg tsawg; Thaum muaj cov tshuaj kub, cov tshuaj tsim tau yuav txuas ntxiv pov tseg, ua kom muaj kev khiav tawm ntawm cov lus ntawm cov lus qhia txog kev tawm tsam thaj chaw, yog li muab cov tshuaj tiv thaiv kab mob hauv qab, yog li muab cov tshuaj tiv thaiv kab mob caj ces, yog li muab cov tshuaj tiv thaiv zoo heev rau nws tej peev xwm.
TusLinthhanum Hexaborate HexaborateCathode muaj qhov tsawg evaporation tus nqi thiab lub neej kev pabcuam ntev thaum muaj kub. Thaum rhuab rau ib lub siab dua, cov nplaim hluav taws xob cov Atoms tsim kev tshaj lij, thaum lub caij Boron Coronutic cov qauv hloov pauv. Cov cuab yeej no maj mam ploj ntawm lab6 cathode thiab tswj hwm ib qho kev ua haujlwm cathode nyob rau tib lub sijhawm. Nyob rau hauv tib qho emission tam sim no, cov evaporation tus nqi ntawm lab6 catreatures, thiab qis evaporation yog qhov tseem ceeb tshaj plaws ntawm kev pabcuam lub neej ntawm kev ua haujlwm ntawm lub neej ntawm Cathodes.

Daim Ntawv Thov:
1. Laumthanum Hexaborate Lab6 Cathohore cov khoom
Lub siab emission tam sim no ceev thiab qis evaporation tus nqi ntawm qhov kub ntawmLab6 Lanthhant Hexabonate HexabonateUa nws cathode cov khoom siv nrog kev ua tau zoo dua, maj mam hloov qee cov tungsten Cathodes hauv kev siv cov ntawv thov. Tam sim no, cov chaw thov tseem ceeb ntawm LAB6 cathode cov ntaub ntawv nrog Lanthant Hexabonum yog raws li hauv qab no:
1.1 Kev Tsim Kho Tshiab Tshiab xws li Microwave nqus hluav taws xob thiab ion burusers thiab qhov chaw muaj kev lag luam zoo li qub, thiab hluav taws xob lasers. Hauv cov kev lag luam technology high-tech no, qhov kev thov kom ua cov ntaub ntawv cathode, muaj kev sib zog ua kom muaj zog, thiab lub neej ntev ntev tau nruj heev.
1.2 Cov Hluav Taws Xob Hluav Taws Xob Vuam kev lag luam, yuav tsum muaj hluav taws xob Beamel, thiab cov khoom siv rau hluav taws xob vuam, thiab cov khoom siv ceev nrawm. Txawm li cas los xij, cov khoom siv tam sim no tsuas yog siv cov kev ua haujlwm tungsten (nrog kev khiav siab thiab qis emission qhov tsis tuaj yeem ua tiav daim ntawv thov. Yog li ntawd, lab6 Cathodes tau hloov tungsten Cathodes nrog lawv cov kev ua haujlwm zoo dua thiab tau siv dav hauv hluav taws xob vuam kev lag luam.
1.3in Kev Tshawb Fawb High-Tech Kuaj Cov Cuab Yeej,Lab66Cathode siv nws lub teeb ci siab, ntev lifespan thiab lwm cov yam ntxwv los hloov cov khoom siv kub kub xws li electronic tshuab tsom, auger spectrometers, thiab electron probes.
1.4Ir Kev lag luam nrawm, Lab 6 tau muaj kev cuam tshuam ntau dua rau ionombardment piv rau cov tsoos tungsten thiab tantalum. Raws li qhov tshwm sim,Lab66Cathodes tau siv dav hauv cov qauv kev sib txawv nrog cov qauv sib txawv xws li Synchrotron thiab Cyclotra Accelerators.
1.5CawvLab66Cathode tuaj yeem siv roj av roj, hlab ntsha laser, thiab magnetron yam nyob rau hauv lub 1.5 kev tso zis raj lag luam.
2. Lab 6, raws li hluav taws xob hauv hluav taws xob hauv kev siv thev naus laus zis, yog siv dav hauv kev lag luam thiab kev tiv thaiv kev lag luam:
2.1 electron emission canhode. Vim tias qhov qis hluav taws xob khiav dim, cov ntaub ntawv cathode nrog cov khoom siv kub siab tam sim no tuaj yeem tau, uas yog cov ntaub ntawv zoo tshaj plaws rau cov khoom siv hluav taws xob siab tshaj plaws Cathountron.
2.2 Lub teeb ci ntsa iab taw tes teeb pom kev. Cov txheej txheem tseem ceeb uas siv rau kev npaj hluav taws xob tsom iav, xws li cov kev lim ultrasonicopes, mos x-ray diffrigactors, thiab lwm yam hluav taws xob teeb pom kev.
2.3 siab ruaj khov thiab cov kev siv lub neej siab. Nws ua tau zoo heev ua rau nws cov ntawv thov hauv Betron nqaj tshav kub, electron nqaj ua kom sov, hluav taws xob welding
