Cov khoom siv dav hlau tau ua pov thawj ua qhov tseem ceeb ntawm cov khoom siv ua ntej. Lawv cov yam ntxwv ntawm cov siab tawv, muaj kev ruaj khov ntawm kev ruaj khov, thiab cov khoom siv hluav taws xob tsis muaj txiaj ntsig zoo ua rau lawv tsis pom kev zoo rau cov ntawv thov. Ntau yam ntawm kev lag luam embraces siv cov khoom siv granite, suav nrog metrology, semiconductor raug, ntsuas qhov muag, thiab aerospace.
Hauv cov ntawv thov metrology, ntsuas ntshav yog qhov tseem ceeb, thiab cov khoom siv granite ua haujlwm rau cov qauv tsim nyog rau kev ntsuas kom muaj kev ntsuas kom muaj kev ntsuas kom haum. Cov metrologist siv cov phiaj granite thiab cubes los teeb tsa cov dav hlau thiab cov ntsiab lus siv, feem. Cov cheebtsam no muab ib qho chaw tiaj tus neeg ncaj qha thiab ruaj khov rau qhov ntsuas pom tseeb ntawm cov micro-nta, xws li tuab, qhov siab, thiab tiaj. Cov khoom siv zoo dua ntawm cov khoom siv hluav taws xob ruaj khov ntawm cov khoom siv tau ua kom muaj zog thaum lub sijhawm, ua rau lawv zoo tshaj rau cov kev siv sijhawm ntev hauv kev txhim kho.
Hauv cov khoom lag luam semiconductor, qhov tseeb thiab zoo ntawm cov khoom yog qhov tseem ceeb rau lawv qhov kev ua tau zoo thiab kev ntseeg tau. Granite cov khoom siv xws li xws li chucks, wafer nqa khoom, thiab tuag lub pob hluav taws xob muaj cov khoom ruaj khov thiab cov kev sib dhos ntawm cov semiconductor wafers. Lub siab txhav thiab tsis muaj thermal nthuav ntawm cov khoom siv granite pab kom txo qhov tshwm sim ntawm kev ua yeeb yam tshwm sim, ua rau muaj txiaj ntsig zoo thiab tsawg dua qhov tsis xws luag. Qhov zoo tshaj corrosion tsis kam ntawm granite kom cov khoom siv nyob ua ke txhim khu kev qha thiab muaj zog nyob rau hauv kev tuag ib puag ncig.
Hauv kev ntsuas kho qhov muag, qhov kev xav tau rau qhov ntsuas thiab qhov tseeb yog qhov siab sib npaug. Cov cheeb tsam granite muab cov chaw ruaj khov thiab kev sib cav dawb rau kev txhim kho thiab kev ntsuas tshuaj xws li cov tshuaj saib xyuas tsom iav, cuam tshuam, thiab lub tshuab laser. Qhov tsawg thermal expansion ntawm cov khoom siv hluav taws xob tsawg tsawg rau qhov ntsuas kub ntawm cov twj paj nruag ntawm cov twj paj nruag, txhim kho lawv qhov tseeb thiab kev ntseeg tau. Ntxiv mus, lub siab txhav ntawm cov khoom siv granite ua rau kev tsim kho cov cuab yeej loj thiab hnyav kho qhov muag tsis muaj kev sib cuam tshuam lawv ruaj khov.
Hauv kev siv Aerospace, kev siv cov khoom siv granite yog ua kom nrov vim lawv lub teeb yuag, lub zog siab, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig. Granite-raws li cov khoom sib xyaw, xws li "Granitium," Tau txais kev txaus siab rau cov khoom zoo dua rau kev tsim kho cov tshuab hluav taws xob hauv cov dav hlau thiab satellites. Cov ntaub ntawv no muaj cov khoom siv zoo heev thiab cov cua sov uas yog qhov tseem ceeb rau kev ua tau zoo ntawm cov chaw ntawm qhov chaw thiab lub dav hlau.
Hauv kev xaus, cov khoom sib xyaw ua si lub luag haujlwm tseem ceeb hauv kev txhim kho thiab kev ua haujlwm ntawm cov khoom lag luam uas muaj kev lag luam hauv ntau yam haujlwm. Lawv cov kev sib xyaw ua ke ntawm cov khoom, suav nrog cov khoom muaj zog loj, ua rau lawv muaj qhov ntsuas tau zoo, ua kom zoo dua qub, thiab ua tau zoo tshaj plaws. Qhov kev sib xyaw ntawm cov khoom siv granite tau ua rau lawv siv hauv cov cuab yeej ntawm cov cuab yeej, suav nrog cov cuab yeej siv medrology, suav nrog cov cuab yeej siv medrology, cov cuab yeej kho qhov muag, thiab cov qauv aerospace. Raws li thev naus laus zis, kev siv cov khoom siv granite yog xav kom loj hlob, ntxiv txhim kho qhov tseeb thiab kev ntseeg tau ntawm niaj hnub muaj kev lag luam niaj hnub.
