Granite, ib lub pob zeb ntuj uas paub txog nws qhov ruaj khov thiab ruaj khov, ua lub luag haujlwm tseem ceeb hauv kev siv cov khoom siv kho qhov muag, tshwj xeeb tshaj yog hauv kev txo qis kev co uas tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm. Hauv cov ntawv thov siab xws li telescopes, microscopes, thiab laser systems, txawm tias qhov kev co me me tuaj yeem ua rau muaj qhov yuam kev loj hauv kev ntsuas thiab kev thaij duab. Yog li ntawd, kev xaiv cov ntaub ntawv siv los tsim cov khoom siv no yog qhov tseem ceeb.
Ib qho ntawm cov laj thawj tseem ceeb uas granite nyiam siv rau hauv kev tsim cov khoom siv kho qhov muag yog nws qhov ceev thiab kev ruaj khov. Cov khoom no tso cai rau granite kom nqus tau thiab tshem tawm lub zog co. Tsis zoo li lwm cov ntaub ntawv uas yuav ua rau muaj kev co lossis ua kom muaj zog, granite muab lub platform ruaj khov uas pab tswj kev ncaj ncees ntawm kev teeb tsa kho qhov muag. Qhov kev ruaj khov no yog qhov tseem ceeb kom ntseeg tau tias cov khoom siv kho qhov muag nyob twj ywm qhov chaw, uas yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig raug.
Qhov ruaj khov ntawm Granite kuj pab txhawb nws txoj kev ua haujlwm zoo hauv kev txo qhov kev co. Kev hloov pauv ntawm qhov kub thiab txias tuaj yeem ua rau cov khoom nthuav dav lossis cog lus, uas tuaj yeem ua rau tsis sib luag. Granite muaj cov coefficient qis ntawm kev nthuav dav thermal, uas txhais tau tias nws tswj nws cov duab thiab qhov loj me ntawm ntau qhov kub sib txawv, ua rau nws muaj txiaj ntsig zoo hauv kev txo qhov kev co.
Ntxiv rau nws cov khoom siv lub cev, granite kuj yog ib qho kev xaiv nrov rau cov khoom siv kho qhov muag siab vim nws cov yam ntxwv zoo nkauj. Qhov zoo nkauj ntuj ntawm granite ntxiv ib qho kev zoo nkauj rau cov cuab yeej uas feem ntau pom hauv cov chaw soj nstuam lossis cov chaw soj ntsuam.
Xaus lus, lub luag haujlwm ntawm granite hauv kev txo kev co hauv cov khoom siv kho qhov muag tsis tuaj yeem raug kwv yees qis. Nws qhov ceev, kev tawv, thiab kev ruaj khov thermal ua rau nws yog cov khoom siv zoo tshaj plaws rau kev ua kom raug thiab kev ntseeg siab hauv cov kab ke kho qhov muag. Raws li thev naus laus zis txuas ntxiv mus, kev siv granite hauv daim teb no yuav tseem yog lub hauv paus rau kev ua tiav qhov kev ua tau zoo tshaj plaws hauv kev siv kho qhov muag.
