Granite tau ntev tau lees paub txog nws qhov ruaj khov thiab ruaj khov, ua rau nws yog cov khoom siv zoo tagnrho rau ntau yam kev siv. Hauv kev siv cov cuab yeej kho qhov muag, kev ntxiv cov khoom granite tuaj yeem txhim kho kev ua tau zoo, qhov tseeb thiab lub neej ntev. Tsab xov xwm no tshawb nrhiav seb granite tuaj yeem txhim kho qhov ua tau zoo ntawm cov khoom siv kho qhov muag li cas.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv granite hauv cov cuab yeej siv kho qhov muag yog nws qhov kev ruaj khov zoo heev. Cov khoom siv kho qhov muag xws li telescopes thiab microscopes xav tau cov platforms ruaj khov kom ntseeg tau tias muaj kev ntsuas thiab kev soj ntsuam raug. Granite lub zog muaj zog txo qis kev co thiab thermal expansion, uas tuaj yeem cuam tshuam cov duab thiab ua rau tsis raug. Los ntawm kev muab lub hauv paus ruaj khov, cov khoom granite pab kom cov optics sib phim, ua rau pom tseeb dua, meej dua.
Tsis tas li ntawd xwb, qhov coefficient ntawm thermal expansion qis ntawm granite yog qhov tseem ceeb rau cov cuab yeej siv kho qhov muag uas ua haujlwm hauv ntau qhov chaw ib puag ncig sib txawv. Kev hloov pauv kub tuaj yeem ua rau cov khoom siv nthuav dav lossis cog lus, ua rau cov khoom siv kho qhov muag tsis sib xws. Kev ruaj khov ntawm granite nyob rau hauv kev hloov pauv kub ua kom muaj txoj kev kho qhov muag sib xws, ua rau muaj kev ntseeg siab ntawm kev ua haujlwm ntawm cov cuab yeej.
Tsis tas li ntawd xwb, qhov ceev ntawm granite ua rau muaj qhov hnyav thiab qhov sib npaug ntawm cov cuab yeej siv kho qhov muag. Cov cuab yeej sib npaug zoo yooj yim dua rau kev khiav lag luam thiab tso cai rau kev hloov kho kom raug dua thaum siv. Qhov no tseem ceeb heev rau cov ntawv thov siab xws li kev thaij duab astrophotography lossis kev tshawb fawb, qhov twg txawm tias qhov kev txav me me tuaj yeem cuam tshuam rau cov txiaj ntsig.
Thaum kawg, qhov zoo nkauj thiab qhov zoo nkauj ntawm granite ua rau nws yog qhov kev xaiv nrov rau cov cuab yeej kho qhov muag zoo. Cov nplaim ci tsis yog tsuas yog ua kom pom kev zoo nkauj xwb tab sis kuj muab qhov chaw du uas yooj yim ntxuav thiab tswj.
Xaus lus, kev koom ua ke ntawm cov khoom granite rau hauv cov cuab yeej siv kho qhov muag tuaj yeem txhim kho lawv cov kev ua tau zoo, muab kev ruaj khov, txo cov teebmeem ntawm kev nthuav dav thermal, xyuas kom muaj kev sib npaug thiab txhim kho tus nqi zoo nkauj. Thaum thev naus laus zis txuas ntxiv mus, lub luag haujlwm ntawm granite hauv kev tsim kho qhov muag yuav dhau los ua qhov tseem ceeb dua, paving txoj hauv kev rau cov cuab yeej siv kom raug thiab txhim khu kev qha dua.
