Daim ntawv thov

Sib nqus resonance cov duab (MRI): Gadolinium yog dav siv nyob rau hauv cov teb kho mob, tshwj xeeb yog tus neeg saib xyuas kev txawv tebchaws. Gadolinium-raws li cov tebchaw txhim kho qhov sib piv ntawm cov duab los ntawm kev hloov cov khoom sib nqus ntawm cov khoom sib nqus ntawm cov qauv hauv dej nyob ze. Daim ntawv thov no yog qhov tseem ceeb rau kuaj xyuas ntau yam kev kho mob, suav nrog cov qog thiab cov kab mob neurological.
Neutron ntes thiab nuclear thov: Gadolinium muaj cov Neutonndon ntes hla ntu, ua rau nws muaj txiaj ntsig zoo nyob rau hauv cov kev siv hluav taws xob nuclear thiab hluav taws xob tiv thaiv. Nws feem ntau siv hauv kev tswj cov pas nrig los pab tswj hwm cov kev ua haujlwm cuav thiab tswj hwm reactor ruaj khov. Gadolinium-based cov ntaub ntawv kuj tau siv hauv cov ntawv thov hluav taws xob thiab cov ntawv thov tiv thaiv kom muaj kev nyab xeeb ntawm nuclear zog tsim kho thiab kho mob hluav taws xob kev kho.
Sib Nqus Cov Ntaub Ntawv: Gadolinium yog siv los ua ntau cov ntaub ntawv sib nqus, suav nrog cov hlau nplaum siab ruaj khov. Nws cov khoom sib nqus magnetic ua rau nws haum rau cov ntaub ntawv cia khoom siv, cov tsheb thauj khoom, thiab cov sensors. Gadolinium-Raws li cov alloys kuj tseem siv los tsim cov cav hlau yees sib nqus, muab cov kev daws teeb meem kom muaj zog.
Phosphors thiab Cov Khoom Siv Tshuab: Gadolinium cov tebchaw tau siv los tsim cov phosphors rau teeb pom kev zoo thiab tso duab thev naus laus zis. Gadolinium oxysulfide (GD2O2S) yog ib feem siv phosphor cov khoom nyob rau hauv Cathode tshav pob (CRTS) thiab lwm yam zaub. Daim ntawv thov no ua rau muaj kev nce qib hauv lub teeb pom kev zoo thiab txhim kho cov xim zoo hauv cov khoom siv hluav taws xob.
