Cov khoom siv granite, xws li cov phaj granite thiab cov granite blocks, feem ntau siv rau hauv kev siv computer tomography (CT) vim lawv qhov ruaj khov siab thiab cov coefficient thermal expansion qis. Hauv tsab xov xwm no, peb yuav tham txog yuav ua li cas siv cov khoom siv granite kom zoo rau kev siv CT hauv kev lag luam.
Ua ntej, cov phaj granite siv tau ua lub hauv paus ruaj khov rau lub tshuab CT scanner. Thaum ua CT scans, kev ruaj khov yog qhov tseem ceeb heev kom ntseeg tau tias qhov tseeb thiab sib xws ntawm cov txiaj ntsig. Cov phaj granite paub txog lawv qhov kev ruaj khov siab thiab cov coefficient thermal expansion qis, uas txhais tau tias lawv tsis tshua muaj peev xwm nthuav dav lossis cog lus vim muaj kev hloov pauv kub. Qhov kev ruaj khov no muab lub hauv paus ruaj khov rau lub tshuab CT scanner, txo qhov kev pheej hmoo ntawm kev ntsuas yuam kev.
Qhov thib ob, cov pob zeb granite siv tau ua cov qauv siv lossis cov cuab yeej ntsuas. Qhov ceev thiab qhov sib xws ntawm granite ua rau nws yog cov khoom siv tsim nyog rau kev tsim cov qauv siv lossis cov cuab yeej ntsuas rau CT scanners. Cov pob zeb no siv tau los ntsuas CT scanner rau kev ntsuas kom raug thiab kom ntseeg tau tias muaj cov txiaj ntsig zoo sib xws.
Qhov thib peb, cov khoom granite siv tau los txo cov suab nrov thiab kev co thaum lub sijhawm CT scans. Granite nqus cov kev co thiab txo cov suab nrov, ua rau nws yog cov khoom siv zoo tagnrho rau cov khoom uas xav tau kom ruaj khov thaum lub sijhawm CT scans. Piv txwv li, cov pob zeb granite siv tau los ua cov khoom txhawb nqa rau cov khoom uas raug scanned kom txo cov kev co thiab xyuas kom meej tias muaj kev ntsuas raug.
Qhov thib plaub, cov khoom granite siv tau los txhim kho qhov tseeb ntawm CT scans. Qhov ruaj khov siab thiab qhov coefficient thermal expansion qis ntawm granite pab txo qhov yuam kev ntsuas thiab txhim kho qhov kev daws teeb meem ntawm CT scans. Qhov kev ntsuas no yog qhov tseem ceeb rau cov ntawv thov xws li kev kuaj mob, qhov twg txawm tias qhov yuam kev ntsuas me tshaj plaws tuaj yeem muaj qhov tshwm sim loj.
Xaus lus, kev siv cov khoom granite hauv kev lag luam CT tuaj yeem txhim kho qhov tseeb, qhov tseeb, thiab kev sib xws ntawm kev ntsuas. Los ntawm kev siv cov phaj granite ua lub hauv paus ruaj khov, cov pob zeb granite ua cov cuab yeej calibration, thiab siv cov khoom granite los nqus suab nrov thiab txo kev co, qhov zoo ntawm CT scans tuaj yeem txhim kho tau zoo heev. Yog li ntawd, kev siv cov khoom granite hauv kev lag luam CT yog ib txoj hauv kev tseem ceeb uas tuaj yeem txhim kho qhov tseeb thiab kev ntseeg siab ntawm cov txiaj ntsig ntsuas.
