Cov cheeb tsam tseem ceeb ntawm cov phiaj xwm tungsten
Khoom siv science
Tungsten hom phiajtuaj yeem siv los ua cov cuab yeej sim hauv kev tshawb fawb cov ntaub ntawv los npaj cov ntaub ntawv tshiab, kawm cov khoom siv thiab ua tus yam ntxwv ntawm cov khoom siv. Piv txwv li, tungsten lub hom phiaj tuaj yeem siv los npaj cov ntaub ntawv nyias nyias los ntawm thermal evaporation lossis ion beam deposition technology, thiab siv rau kev tshawb fawb txog kev hloov kho deg, kev npaj nanomaterial, thiab lwm yam.
Electronics
Tungsten lub hom phiaj muaj cov ntawv thov tseem ceeb hauv kev siv hluav taws xob. Tungsten lub hom phiaj tuaj yeem siv los ua cov khoom siv hluav taws xob los tsim cov khoom siv xws li cov raj electron, cathode ray tubes thiab electron microscopes. Tsis tas li ntawd, tungsten lub hom phiaj tseem tuaj yeem siv los tsim cov khoom siv optoelectronic xws li thaj chaw emission tso saib tungsten filament teeb.
Lub zog teb
Nyob rau hauv lub zog teb, tungsten lub hom phiaj yog dav siv nyob rau hauv nuclear fusion thwmsim thiab nuclear reactor technology. Tungsten lub hom phiaj tuaj yeem siv los ua lub hom phiaj hauv plasma fusion reactors los tiv thaiv kev cuam tshuam los ntawm cov kab hluav taws xob siab thiab tsim cov kev xav tau fusion. Tsis tas li ntawd, tungsten lub hom phiaj tseem tuaj yeem siv rau hauv kev sim ua kua hlau cuam tshuam hauv kev siv roj nuclear.
