Cov cuab yeej ntsuas sib luag ntawm granite yog cov cuab yeej tseem ceeb hauv ntau qhov chaw, tshwj xeeb tshaj yog hauv kev tsim kho, kev tsim kho, thiab kev ua haujlwm kom raug. Lawv cov yam ntxwv tshwj xeeb, suav nrog kev ruaj khov, kev ua haujlwm ntev, thiab kev tiv taus kev nthuav dav thermal, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau qhov tseeb thiab kev ua haujlwm raug. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qee qhov kev siv feem ntau rau cov cuab yeej ntsuas sib luag ntawm granite.
Ib qho ntawm cov ntawv thov tseem ceeb ntawm cov granite parallel rulers yog nyob rau hauv thaj chaw ntawm metrology. Cov rulers no feem ntau siv ua ke nrog cov cuab yeej ntsuas kom ntseeg tau tias qhov kev ntsuas yog qhov tseeb. Piv txwv li, thaum calibrating lub tshuab lossis ntsuas ib qho khoom, ib tug granite parallel ruler tuaj yeem muab ib qho chaw ruaj khov, tso cai rau kev sib phim thiab kev ntsuas kom raug. Qhov no yog qhov tseem ceeb hauv kev lag luam uas txawm tias qhov kev hloov pauv me me tuaj yeem ua rau muaj qhov yuam kev loj.
Hauv kev tsim vaj tsev, cov kav hlau granite parallel yog cov cuab yeej siv tau zoo rau kev kos duab thiab cov phiaj xwm kom raug. Cov kws kes duab vajtse feem ntau siv cov kav hlau no los xyuas kom meej tias lawv cov qauv tsim yog sib npaug thiab hauv qhov loj. Qhov ruaj khov ntawm granite tso cai rau nws kos cov kab huv si, ncaj, uas yog qhov tseem ceeb rau kev tsim cov phiaj xwm qib siab. Tsis tas li ntawd, qhov hnyav ntawm granite pab kom tus kav hlau nyob hauv qhov chaw, txo qhov kev pheej hmoo ntawm nws swb thaum lub sijhawm kos duab.
Lwm qhov kev siv tseem ceeb yog ua haujlwm ntoo thiab ua hlau. Cov kws ua tes siv cov kav hlau granite parallel los teeb tsa cov jigs thiab fixtures, kom ntseeg tau tias muaj kev txiav thiab sib txuas meej. Qhov chaw tiaj tus ntawm cov kav hlau granite muab lub hauv paus ruaj khov rau kev ntsuas thiab cim, uas yog qhov tseem ceeb rau kev ua tiav qhov zoo hauv cov haujlwm ntoo thiab hlau.
Tag nrho hauv txhua qhov, kev sib qhia cov ntaub ntawv siv ntawm cov granite parallel rulers qhia txog lawv qhov kev ua tau zoo thiab qhov tseem ceeb thoob plaws ntau yam lag luam. Txij li metrology mus rau kev tsim kho thiab kev ua haujlwm tes ua, cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev ua kom raug thiab meej, ua rau lawv tsis tseem ceeb hauv txhua qhov chaw ua haujlwm.
