Hauv kev ua haujlwm ntawm cov khoom siv kho qhov muag kom raug, qhov ruaj khov ntawm cov tshuab kho qhov muag yog qhov tseem ceeb heev. Ib qho kev daws teeb meem tshiab uas tau nyiam ntau tus neeg saib xyuas hauv xyoo tas los no yog kev koom ua ke ntawm cov khoom granite rau hauv cov khoom siv kho qhov muag. Granite, ib lub pob zeb ntuj uas paub txog nws qhov ruaj khov thiab rigidity, muaj ntau yam zoo uas tuaj yeem txhim kho qhov kev ua tau zoo thiab kev ntseeg siab ntawm cov tshuab kho qhov muag.
Ua ntej, qhov ruaj khov ntawm granite yog qhov tseem ceeb hauv kev txo qhov kev co. Cov kab ke kho qhov muag feem ntau rhiab rau kev cuam tshuam sab nraud, uas tuaj yeem ua rau tsis sib haum thiab ua rau cov duab tsis zoo. Los ntawm kev siv cov khoom granite xws li lub hauv paus thiab kev txhawb nqa, cov kab ke tuaj yeem tau txais txiaj ntsig los ntawm granite lub peev xwm los nqus thiab txo qhov kev co. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj kev co tshuab, xws li chaw kuaj mob lossis chaw ua haujlwm.
Tsis tas li ntawd xwb, qhov ruaj khov ntawm granite ua lub luag haujlwm tseem ceeb hauv kev tswj hwm qhov sib dhos ntawm qhov muag. Kev hloov pauv ntawm qhov kub thiab txias tuaj yeem ua rau cov khoom siv nthuav dav lossis cog lus, ua rau cov khoom siv kho qhov muag tsis sib xws. Granite muaj cov coefficient qis ntawm kev nthuav dav thermal thiab tseem ruaj khov hla ntau qhov kub thiab txias, ua kom ntseeg tau tias cov khoom siv kho qhov muag tswj hwm qhov sib dhos meej. Qhov kev ruaj khov no yog qhov tseem ceeb rau cov ntawv thov uas xav tau qhov tseeb siab, xws li telescopes, microscopes thiab laser systems.
Tsis tas li ntawd xwb, qhov kev tiv thaiv kev hnav ntawm granite pab ua kom lub cev pom kev ntev dua. Tsis zoo li lwm yam khoom siv uas yuav lwj mus raws sijhawm, granite tswj nws cov qauv kom ruaj khov, muab lub hauv paus ruaj khov rau cov khoom siv pom kev. Qhov kev ruaj khov no tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub cev xwb tab sis kuj txo cov nqi kho thiab lub sijhawm tsis ua haujlwm.
Hauv kev xaus lus, kev koom ua ke ntawm cov khoom granite rau hauv cov tshuab kho qhov muag muaj qhov zoo tseem ceeb hauv kev ruaj khov, kev ua haujlwm thermal, thiab kev ua haujlwm ntev. Raws li qhov kev thov rau cov khoom siv kho qhov muag precision txuas ntxiv mus, kev siv granite yuav dhau los ua ntau dua, ua kom muaj kev ua tau zoo tshaj plaws ntawm cov tshuab kho qhov muag hauv ntau qhov chaw nyuaj.
