Granite yog ib hom pob zeb igneous uas tau siv dav hauv ntau yam lag luam. Ib qho ntawm cov ntawv thov tshiab thiab tshiab tshaj plaws rau cov khoom siv no yog nyob rau hauv kev lag luam suav tomography (CT), uas koom nrog kev siv tshuab X-ray los tsim cov duab ntxaws ntawm cov khoom siv sab hauv. Hauv tsab xov xwm no, peb yuav tshawb txog qhov zoo thiab qhov tsis zoo ntawm kev siv granite hauv kev lag luam CT.
Qhov zoo:
1. Kev kub ceev: Granite yog cov khoom siv tuab heev, ua rau nws tiv taus tawg thiab deformation nyob rau hauv kev ntxhov siab. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv CT scanners, uas yuav tsum muaj cov qauv ruaj khov thiab ruaj khov los tuav lub tshuab luam ntawv hauv qhov chaw.
2. Tsawg thermal expansion: Granite muaj qhov thermal expansion coefficient tsawg heev, txhais tau hais tias nws tsis nthuav lossis cog lus loj heev nyob rau hauv qhov kev hloov ntawm qhov kub thiab txias. Qhov no yog qhov tseem ceeb rau CT scanning, vim thermal expansion tuaj yeem ua rau muaj kev cuam tshuam ntawm cov duab tsim.
3. High radiopacity: Granite muaj lub siab radiopacity, txhais tau hais tias nws absorbs X-rays yooj yim dua li ntau lwm yam ntaub ntawv. Cov cuab yeej no tso cai rau cov duab meej dua thiab cov ncauj lus kom ntxaws ntxiv kom tsim tau thaum CT scanning.
4. Ntev ntev: Granite yog cov khoom siv ruaj khov heev, uas txhais tau hais tias nws tuaj yeem tiv taus rov siv dua thiab raug rau cov xwm txheej hnyav yam tsis muaj kev puas tsuaj. Qhov no ua rau nws xaiv zoo rau lub tshuab CT ntev ntev.
5. Zoo acoustic damping: Granite yog ib qho zoo acoustic damper, txhais tau tias nws tuaj yeem pab txo cov suab nrov los ntawm CT scanner. Qhov no tuaj yeem txo qhov kev pheej hmoo ntawm kev puas tsuaj rau lub scanner thiab txhim kho tag nrho cov txheej txheem duab zoo.
Qhov tsis zoo:
1. Nqi: Granite yog ib yam khoom kim heev, uas tuaj yeem ua rau nws raug nqi txwv rau qee lub tuam txhab lossis cov koom haum. Qhov no tuaj yeem txwv nws qhov muaj thiab siv tau rau kev lag luam CT.
2. Nyhav: Txawm hais tias nws cov khoom muaj zog thiab ruaj khov, granite tuaj yeem hnyav thiab yuav xav tau kev txhawb nqa ntxiv rau hauv lub tshuab CT. Qhov no tuaj yeem ua rau tag nrho qhov hnyav thiab qhov loj ntawm lub scanner, ua rau nws tsis tshua muaj txav thiab nyuaj rau nruab.
3. Brittle: Txawm hais tias granite paub txog nws lub zog thiab ua haujlwm ntev, nws kuj yog cov khoom siv tawv tawv uas tuaj yeem ua rau tawg lossis tawg hauv qee yam mob. Qhov no tuaj yeem ua rau muaj kev pheej hmoo rau kev ncaj ncees thiab raug ntawm CT scans.
4. Txwv tsis pub customization: Raws li granite yog cov khoom siv ntuj tsim, nws tuaj yeem nyuaj rau kev kho lossis hloov kho kom tau raws li cov kev xav tau tshwj xeeb. Qhov no tuaj yeem txwv nws ntau yam thiab yoog raws rau qee yam kev siv CT.
Xaus:
Zuag qhia tag nrho, granite yog cov khoom cog lus siv rau hauv kev lag luam CT scanning. Nws lub siab ntom ntom ntom ntom, tsis muaj hluav taws xob kub ua rau nws zoo rau kev tsim cov duab ntshiab thiab cov ncauj lus kom ntxaws ntawm cov qauv sab hauv. Txawm li cas los xij, nws cov nuj nqis, qhov hnyav, thiab brittleness tuaj yeem txwv nws txoj kev siv hauv qee qhov kev siv, thaum nws qhov kev txwv tsis pub muaj peev xwm kuj tuaj yeem yog qhov tsis zoo hauv qee qhov xwm txheej. Txawm hais tias muaj qhov tsis zoo no, cov txiaj ntsig ntawm kev siv granite hauv kev lag luam CT tshaj qhov tsis zoo, ua rau nws muaj txiaj ntsig zoo rau cov txheej txheem thev naus laus zis tseem ceeb no.
