Cov kws tshawb fawb siv cov kev txawj ntse txawj ntse los nrhiav cov khoom sib nqus tshiab uas tsis siv cov ntsiab lus tseem ceeb. Ib pab neeg tshawb fawb ntawm US Department of Energy's Ames National Laboratory tau tsim ib lub tshuab kawm tshiab rau kev tshawb pom cov khoom siv hlau nplaum ruaj khov uas tsis muaj cov ntsiab lus tseem ceeb. Tus qauv kwv yees Curie kub ntawm cov khoom siv tshiab ua ke. Qhov no yog thawj kauj ruam tseem ceeb hauv kev siv kev txawj ntse txawj ntse los kwv yees cov khoom siv hlau nplaum ruaj khov tshiab. Tus qauv txhawb pab pawg neeg tsis ntev los no tau tsim muaj peev xwm los tshawb pom cov ntaub ntawv tsis tshua muaj hauv ntiaj teb thermodynamically ruaj khov.
Cov kws tshawb fawb ntawm Ames National Laboratory tau tsim cov qauv kev kawm tshuab uas tuaj yeem kwv yees cov khoom siv hlau nplaum tshiab yam tsis siv cov khoom tsawg. Txoj hauv kev tshiab no tsom rau Curie qhov kub ntawm cov ntaub ntawv muab txoj hauv kev zoo dua rau kev siv thev naus laus zis yav tom ntej.
Qhov tseem ceeb ntawm High-Performance Magnets
Cov hlau nplaum ua haujlwm siab yog qhov tseem ceeb rau cov thev naus laus zis xws li cua zog, cov ntaub ntawv khaws cia, hluav taws xob tsheb thiab cov tub yees sib nqus. Cov hlau nplaum no muaj cov ntaub ntawv tseem ceeb xws li cobalt thiab lub ntiaj teb tsis tshua muaj xws li neodymium thiab dysprosium. Cov khoom siv no muaj kev xav tau siab, tab sis cov khoom siv tsawg. Qhov xwm txheej no tau ua rau cov neeg tshawb nrhiav nrhiav txoj hauv kev los tsim cov khoom siv hlau nplaum tshiab uas txo cov ntaub ntawv tseem ceeb.
Lub luag haujlwm ntawm kev kawm tshuab
Machine Learning (ML) yog ib hom kev txawj ntse txawj ntse. Nws yog tsav los ntawm lub computer algorithms, siv cov ntaub ntawv thiab sim-thiab-yuam kev algorithms los txuas ntxiv txhim kho kev kwv yees. Pab neeg tshawb fawb siv cov ntaub ntawv sim thiab theoretical qauv ntawm Curie kub los qhia ML algorithm. Qhov kub Curie yog qhov kub siab tshaj plaws uas cov khoom tseem sib nqus.
Yaroslav Mudryk, tus kws tshawb fawb hauv Ames Laboratory thiab tus thawj coj loj ntawm pab pawg tshawb fawb tau hais tias "Nrhiav cov tebchaw nrog kub Curie siab yog thawj kauj ruam tseem ceeb hauv kev tshawb pom cov ntaub ntawv uas tuaj yeem sib nqus ntawm qhov kub thiab txias. "Qhov no yog qhov tseem ceeb tsis yog rau kev tsim cov hlau nplaum ruaj khov, tab sis kuj yog rau kev tsim ntawm lwm cov khoom siv hlau nplaum ua haujlwm."
Mudrick ntseeg tias kev tshawb nrhiav cov ntaub ntawv tshiab yog qhov nyuaj vim tias kev tshawb nrhiav cov ntaub ntawv tshiab tau ua ib txwm ua los ntawm kev sim, uas yog kim thiab siv sijhawm. Txawm li cas los xij, siv txoj hauv kev ML tuaj yeem txuag sijhawm thiab peev txheej.
Qauv kuaj thiab validation
Txhawm rau kom paub tseeb tus qauv, pab pawg siv cov khoom sib txuas raws li cerium, zirconium thiab hlau. Lub tswv yim tau thov los ntawm Andriy Palasyuk, tus kws tshawb fawb ntawm Ames Laboratory thiab tus tswv cuab ntawm pab pawg tshawb fawb. Nws vam tias yuav tsom mus rau cov khoom siv hlau nplaum tsis paub raws li lub ntiaj teb-ntau cov ntsiab lus. Palaschuk tau hais tias: "Lub super hlau nplaum tom ntej yuav tsum tsis yog tsuas yog muaj kev ua tau zoo, tab sis kuj vam khom cov khoom siv hauv tsev ntau.
Palaschuk koom tes nrog pab pawg tshawb fawb Tyler Del Rose, lwm tus kws tshawb fawb Ames Laboratory, los ua ke thiab ua tus yam ntxwv ntawm cov hlau. Lawv pom tias tus qauv ML tau ua tiav qhov ntsuas kub ntawm Curie ntawm cov ntaub ntawv sib tw. Qhov kev vam meej no yog thawj kauj ruam tseem ceeb hauv txoj hauv kev los ntawm kev tsim cov hlau nplaum ruaj khov tshiab rau kev siv thev naus laus zis yav tom ntej.
"Peb tab tom sau physics-kev paub tshuab kev kawm rau lub neej yav tom ntej," Singer hais.
