Thaum xaiv lub mount rau cov khoom siv rhiab heev xws li lub tshuab suab, cov cuab yeej tshawb fawb, lossis cov tshuab lag luam, kev xaiv cov khoom siv tuaj yeem cuam tshuam rau kev ua tau zoo. Cov ntaub ntawv siv feem ntau suav nrog granite, txhuas thiab hlau. Txhua yam khoom siv muaj cov yam ntxwv tshwj xeeb uas cuam tshuam rau nws lub peev xwm los nqus kev co, uas yog qhov tseem ceeb rau kev tswj hwm qhov tseeb thiab meej hauv ntau yam kev siv.
Cov hauv paus granite paub txog lawv cov peev xwm nqus tau zoo heev. Qhov ntom thiab tawv ntawm granite ua rau nws nqus tau thiab tshem tawm cov kev co. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov kev co sab nraud yuav cuam tshuam rau kev ntsuas rhiab heev lossis lub suab zoo. Granite cov yam ntxwv ntuj tsim pab kom cov khoom siv ruaj khov, ua rau nws yog qhov kev xaiv zoo rau cov khoom siv suab zoo thiab cov twj paj nruag precision.
Piv rau qhov ntawd, cov hauv paus txhuas thiab hlau, txawm tias muaj zog thiab ruaj khov, tsis nqus tau kev co zoo li granite. Aluminium yog lub teeb thiab tuaj yeem tsim rau kev siv tshwj xeeb, tab sis nws feem ntau xa kev co es tsis yog nqus nws. Hlau, ntawm qhov tod tes, hnyav dua thiab tawv dua li txhuas, uas pab txo qhov kev co rau qee qhov. Txawm li cas los xij, nws tseem tsis muaj cov yam ntxwv zoo tshaj plaws ntawm granite uas nqus tau kev co.
Tsis tas li ntawd xwb, feem ntau cov granite muaj cov zaus resonant qis dua li txhuas thiab hlau, uas txhais tau tias nws tuaj yeem tswj tau ntau yam zaus zoo dua yam tsis tau ua kom lawv loj dua. Qhov no ua rau cov granite bases zoo tshwj xeeb hauv cov chaw uas muaj kev co qis zaus yog qhov txhawj xeeb.
Xaus lus, thaum nws los txog rau kev nqus dej poob siab, granite yog qhov kev xaiv zoo tshaj plaws piv rau cov hauv paus txhuas lossis hlau. Nws qhov ceev, qhov tawv thiab qhov zaus resonant qis ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab kev cuam tshuam kev co tsawg kawg nkaus. Rau cov neeg uas tab tom nrhiav kev ua tau zoo tshaj plaws hauv lawv cov khoom siv rhiab heev, kev nqis peev hauv granite hauv paus yog qhov kev txiav txim siab zoo.
