Ntxiv La-Ce alloys rau cov ntaub ntawv no txhim kho lawv cov khoom sib nqus, ua rau lawv muaj txiaj ntsig zoo thiab ua haujlwm zoo hauv lawv cov ntawv thov.

Kev ua haujlwm siab hydrogen cia alloy

Lwm daim ntawv cog lus rau lanthanum-cerium alloys yog nyob rau hauv hydrogen cia. Cov alloy yog siv los tsim cov kev ua haujlwm siab tsis tshua muaj hauv ntiaj teb hydrogen cia alloys, uas yog qhov tseem ceeb rau cov khoom siv hauv xeev hydrogen cia daws teeb meem. Raws li lub ntiaj teb hloov mus rau lub zog huv si, qhov kev xav tau ntawm cov khoom siv hydrogen khaws cia tau nce ntxiv. Cov khoom ntawm La-Ce alloys ua rau lawv cov neeg sib tw zoo tshaj plaws rau kev txhim kho cov khoom siv hydrogen siab heev uas muaj peev xwm khaws tau zoo thiab tso tawm hydrogen.

Lub zeem muag yav tom ntej ntawm thermal rwb thaiv tsev thiab cov khoom siv thermal cia

Lanthanum-cerium alloys muaj peev xwm siv tau tshaj lawv cov kev siv tam sim no. Cov kws tshawb fawb tab tom tshawb nrhiav nws lub peev xwm hauv kev rwb thaiv tsev thiab thermal cia daim ntaub ntawv. Cov khoom tshwj xeeb ntawm La-Ce alloys tuaj yeem pab txhawb kev txhim kho cov ntaub ntawv rwb thaiv tsev siab heev nrog kev ua haujlwm kub zoo, ua rau lawv tsim nyog rau kev siv hluav taws xob txuag hluav taws xob thiab kev lag luam. Tsis tas li ntawd, nws lub peev xwm khaws cia thermal tuaj yeem siv rau cov ntawv thov hauv lub tshuab hluav taws xob tauj dua tshiab uas muaj lub zog khaws cia yog qhov tseem ceeb.

Hauv kev xaus

Hauv cov ntsiab lus, lanthanum-cerium (La-Ce) alloy hlau yog cov khoom siv ntau yam nrog ntau yam kev siv hauv ntau yam lag luam. Nws cov khoom siv hluav taws xob zoo heev, sib nqus thiab kho qhov muag ua rau nws tsim nyog siv rau hauv cov hlau tsis tshua muaj hauv ntiaj teb, cov alloys sib zog, cov hlau nplaum ruaj khov thiab cov khoom siv hydrogen. Raws li kev tshawb fawb txuas ntxiv mus nthuav tawm cov ntawv thov muaj peev xwm tshiab, La-Ce alloys xav tias yuav ua lub luag haujlwm tseem ceeb hauv kev tsav tsheb thev naus laus zis thiab txhawb kev txhim kho kom ruaj khov rau yav tom ntej.
