Cov ntsuas granite tau dhau los ua ib qho cuab yeej tseem ceeb hauv kev ua cov txheej txheem kho tshuab, muab kev ua haujlwm raug thiab ruaj khov uas yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo. Kev siv cov ntsuas granite hauv thaj chaw no yog vim lawv cov yam ntxwv, uas ua rau lawv zoo tagnrho rau ntau yam kev ntsuas thiab kev sib dhos.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov granite rulers yog lawv qhov ruaj khov. Granite yog cov khoom siv ntom thiab khov kho, uas txo qhov kev pheej hmoo ntawm kev hloov pauv hauv qab cov khoom hnyav lossis thaum muaj kev hloov pauv kub. Qhov kev ruaj khov no ua kom ntseeg tau tias kev ntsuas tseem raug raws sijhawm, ua rau granite rulers yog qhov kev xaiv txhim khu kev qha rau cov kws kho tshuab thiab cov engineers. Hauv kev ua cov khoom siv kho tshuab, qhov twg qhov tseeb yog qhov tseem ceeb, kev siv cov granite rulers tuaj yeem txhim kho qhov zoo ntawm cov khoom tiav.
Cov ntsuas granite feem ntau siv rau kev teeb tsa tshuab, sib dhos cov khoom ua haujlwm, thiab xyuas seb qhov chaw tiaj tus. Lawv cov npoo ncaj tso cai rau kev ntsuas kom raug, uas yog qhov tseem ceeb thaum ua cov khoom uas xav tau kev kam rau siab. Tsis tas li ntawd, cov ntsuas granite tuaj yeem siv ua ke nrog lwm cov cuab yeej ntsuas, xws li calipers thiab micrometers, kom ntseeg tau tias muaj kev raug thoob plaws hauv cov txheej txheem tsim khoom.
Lwm qhov tseem ceeb ntawm kev siv cov cuab yeej granite yog nyob rau theem tshuaj xyuas ntawm kev ua haujlwm kho tshuab. Lawv ua haujlwm ua qhov chaw siv rau kev ntsuas qhov loj ntawm cov khoom siv tshuab, pab txheeb xyuas txhua qhov kev hloov pauv ntawm qhov kev kam rau siab tshwj xeeb. Lub peev xwm no yog qhov tseem ceeb rau kev tswj hwm zoo thiab xyuas kom meej tias cov khoom ua tau raws li cov qauv kev lag luam.
Tsis tas li ntawd xwb, cov ntsuas granite tiv taus kev hnav thiab xeb, uas ua rau lawv siv tau ntev hauv chaw ua haujlwm. Qhov kev ruaj khov no tsis yog tsuas yog txo qhov xav tau hloov pauv ntau zaus xwb tab sis kuj ua kom ntseeg tau tias kev nqis peev rau cov cuab yeej ntsuas zoo yuav them rov qab raws sijhawm.
Xaus lus, kev siv cov granite rulers hauv kev ua cov khoom siv yog qhov tseem ceeb heev. Lawv qhov kev ua kom raug, kev ruaj khov, thiab kev ua kom ruaj khov ua rau lawv yog qhov kev xaiv zoo rau cov kws tshaj lij uas nrhiav kev ua tiav zoo hauv lawv txoj haujlwm. Thaum thev naus laus zis txuas ntxiv mus, lub luag haujlwm ntawm granite rulers hauv kev ua kom zoo thiab raug hauv kev ua cov khoom siv yuav tseem ceeb heev.
