Vim li cas granite siv rau hauv cov khoom siv ntsuas precision?

Granite yog ib yam khoom siv uas siv ntau hauv cov khoom siv ntsuas qhov tseeb vim muaj ntau yam laj thawj. Nws cov yam ntxwv tshwj xeeb ua rau nws zoo tagnrho rau kev ua kom muaj kev ntsuas raug thiab txhim khu kev qha hauv ntau yam lag luam.

Ib qho ntawm cov laj thawj tseem ceeb uas ua rau granite siv rau hauv cov khoom siv ntsuas qhov tseeb yog nws qhov ruaj khov thiab ua tau ntev. Granite yog cov khoom siv ntom thiab tawv uas tiv taus kev hnav thiab kev hloov pauv, ua rau nws ntseeg tau heev ntawm kev tswj hwm qhov tseeb dhau sijhawm. Nws qhov kev tiv taus kev hloov pauv kub thiab kev xeb ntxiv txhim kho nws qhov ruaj khov, ua kom ntseeg tau tias kev ntsuas sib xws thiab raug.

Ntxiv rau nws qhov ruaj khov, granite kuj muaj cov khoom zoo heev uas tiv thaiv kev co. Qhov no yog qhov tseem ceeb rau cov khoom siv ntsuas qhov tseeb vim nws pab txo cov teebmeem ntawm kev co sab nraud thiab ua kom cov kev ntsuas tsis cuam tshuam los ntawm kev txav mus los lossis kev co tsis xav tau. Granite lub peev xwm los nqus thiab tshem tawm kev co ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tswj hwm kev ntsuas kev ncaj ncees hauv cov ntawv thov rhiab heev.

Tsis tas li ntawd xwb, granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tsis tshua muaj peev xwm nthuav dav lossis cog lus nrog kev hloov pauv ntawm qhov kub thiab txias. Cov cuab yeej no tseem ceeb rau cov khoom siv ntsuas qhov tseeb vim nws pab tswj kev ruaj khov ntawm qhov ntev thiab txo qhov kev pheej hmoo ntawm kev hloov pauv thermal, ua kom ntseeg tau tias kev ntsuas tseem raug nyob rau hauv ntau yam xwm txheej ib puag ncig.

Lwm qhov zoo ntawm granite yog nws txoj kev tiv thaiv kev khawb thiab kev sib txhuam, uas pab tswj qhov chaw ntawm koj cov khoom siv ntsuas kom raug raws sijhawm. Qhov no ua kom qhov chaw siv los ntsuas tseem du thiab tiaj tus, ua rau muaj kev ntsuas tas mus li thiab txhim khu kev qha yam tsis muaj kev pheej hmoo ntawm qhov tsis zoo ntawm qhov chaw cuam tshuam rau cov txiaj ntsig.

Zuag qhia tag nrho, qhov kev sib xyaw ua ke ntawm kev ruaj khov, kev co damping, thermal stability thiab hnav tsis kam ua rau granite yog cov khoom siv zoo tagnrho rau cov khoom siv ntsuas qhov tseeb. Nws lub peev xwm los tswj qhov tseeb thiab kev ntseeg tau nyob rau hauv cov xwm txheej nyuaj ua rau nws yog thawj qhov kev xaiv rau ntau yam kev siv metrology, suav nrog cov tshuab ntsuas sib koom ua ke, theem thiab cov khoom sib piv optical. Yog li ntawd, granite tseem ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau qhov tseeb thiab zoo ntawm kev ntsuas hauv ntau yam lag luam.
