Hauv kev siv cov khoom siv kho qhov muag kom raug, kev xaiv cov khoom siv rau kev teeb tsa yog qhov tseem ceeb heev. Granite yog ib yam khoom siv uas sawv tawm rau nws cov yam ntxwv tshwj xeeb. Cov txiaj ntsig ntawm kev siv granite rau kev teeb tsa cov khoom siv kho qhov muag muaj ntau yam, ua rau nws yog thawj qhov kev xaiv rau cov kws tshaj lij hauv daim teb no.
Ua ntej tshaj plaws, granite paub txog nws qhov ruaj khov. Nws yog qhov ruaj khov heev kom txo qis kev co thiab kev txav mus los uas tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm qhov muag. Qhov kev ruaj khov no yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev sib dhos thiab kev ntsuas kom raug, xws li telescopes, microscopes, thiab laser systems. Los ntawm kev siv lub granite sawv ntsug, cov neeg siv tuaj yeem ua kom lawv cov khoom siv kho qhov muag tseem nyob hauv qhov chaw ruaj khov rau kev ntsuas thiab kev soj ntsuam kom raug.
Lwm qhov zoo ntawm granite yog nws qhov thermal stability. Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov feature no yog qhov tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog kev hloov pauv ntawm qhov kub thiab txias, vim nws pab tswj kev ncaj ncees ntawm kev sib dhos optical. Yog li ntawd, granite txhawb nqa muab kev ua tau zoo sib xws nyob rau hauv ntau yam kev ua haujlwm.
Tsis tas li ntawd xwb, granite ruaj khov heev thiab tiv taus kev hnav thiab rhuav. Tsis zoo li lwm yam khoom siv uas yuav lwj mus raws sijhawm lossis yooj yim puas tsuaj, granite tswj nws cov qauv kom ruaj khov, ua kom ntseeg tau tias nws txhawb nqa cov khoom siv kho qhov muag tau ntev. Qhov kev ruaj khov no txhais tau tias cov nqi kho qis dua thiab lub neej ntev dua ntawm lub kaw lus.
Tsis tas li ntawd xwb, qhov zoo nkauj ntawm granite tsis tuaj yeem tsis quav ntsej. Nws qhov kev zoo nkauj ntuj thiab qhov tiav tiav ua rau nws zoo tagnrho rau cov chaw soj nstuam thiab cov chaw tshawb fawb los txhim kho qhov chaw ib puag ncig uas ua haujlwm kho qhov muag.
Hauv kev xaus lus, cov txiaj ntsig ntawm kev siv granite rau kev teeb tsa cov khoom siv kho qhov muag yog qhov tseeb. Nws qhov kev ruaj khov, kev ua haujlwm thermal, kev ruaj khov thiab kev zoo nkauj ua rau nws zoo tagnrho rau cov kws tshaj lij nrhiav kev daws teeb meem txhim khu kev qha thiab kev ua tau zoo hauv kev kho qhov muag. Los ntawm kev nqis peev rau hauv granite mounts, cov neeg siv tuaj yeem ua kom qhov tseeb thiab lub neej ntev ntawm lawv cov kab ke kho qhov muag.
