Cov hauv paus tshuab granite tau ntev los lawm suav hais tias yog cov khoom siv zoo tshaj plaws rau cov khoom siv computer tomography hauv kev lag luam vim lawv qhov ceev ceev, kev tawv, thiab cov yam ntxwv ntuj tsim uas ua rau cov khoom ntub dej. Txawm li cas los xij, zoo li txhua yam khoom siv, granite tsis yog tsis muaj qhov tsis zoo, thiab muaj ntau qhov tsis zoo uas tuaj yeem tshwm sim hauv cov hauv paus tshuab granite uas tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom siv computer tomography hauv kev lag luam.
Muaj ib qho teeb meem uas tshwm sim hauv lub tshuab granite yog nws lub hauv paus tsis khov. Txawm hais tias nws lub cev tsis khov kho los, granite tseem tuaj yeem tsis khov thaum raug qhov kub thiab txias hloov pauv lossis thaum raug kev ntxhov siab ntau. Qhov no tuaj yeem ua rau lub hauv paus tshuab tsis sib dhos, uas tuaj yeem ua rau muaj qhov yuam kev hauv cov txheej txheem CT scanning.
Lwm qhov tsis zoo uas tuaj yeem tshwm sim hauv lub hauv paus tshuab granite yog tawg. Txawm hais tias granite yog cov khoom siv ruaj khov uas tuaj yeem tiv taus ntau qhov kev hnav thiab tsim kua muag, nws tsis tiv thaiv kev tawg, tshwj xeeb tshaj yog tias nws raug kev ntxhov siab ntau zaus lossis kev co siab. Yog tias tsis kho, cov kab nrib pleb no tuaj yeem ua rau lub hauv paus tshuab puas tsuaj thiab ua rau puas tsuaj ntxiv.
Qhov tsis zoo thib peb uas tuaj yeem tshwm sim hauv lub hauv paus tshuab granite yog porosity. Granite yog ib yam khoom siv ntuj, thiab yog li ntawd, nws tuaj yeem muaj cov hnab me me ntawm huab cua lossis lwm yam khoom uas tuaj yeem ua rau lub hauv paus tshuab tsis muaj zog. Qhov porosity no kuj tseem tuaj yeem ua rau lub hauv paus tshuab yooj yim raug puas tsuaj los ntawm cov yam ntxwv ib puag ncig xws li av noo thiab kev hloov pauv kub.
Thaum kawg, qhov tsis zoo thib plaub uas tuaj yeem tshwm sim hauv lub tshuab granite yog qhov tsis sib xws ntawm qhov chaw. Txawm hais tias granite yog lub npe nrov rau nws qhov chaw du, tseem tuaj yeem muaj qhov tsis zoo me me lossis qhov tsis sib xws uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv computer tomography. Cov kev tsis sib xws no tuaj yeem ua rau CT scan raug cuam tshuam lossis tsis meej, uas tuaj yeem ua rau qhov tseeb ntawm cov txiaj ntsig tsis zoo.
Txawm hais tias muaj cov teeb meem no los xij, cov hauv paus tshuab granite tseem yog qhov kev xaiv nrov rau cov khoom siv computer tomography hauv kev lag luam vim lawv cov khoom zoo heev. Los ntawm kev ua cov kauj ruam los txo qhov cuam tshuam ntawm cov teeb meem no, xws li siv cov granite zoo thiab saib xyuas lub hauv paus tshuab kom tsis tu ncua rau cov cim ntawm kev hnav thiab tsim kua muag, nws muaj peev xwm tswj tau qhov kev ua tau zoo ntawm cov khoom siv computer tomography hauv kev lag luam thiab xyuas kom meej tias nws txuas ntxiv ua haujlwm ntawm qib siab tshaj plaws ntawm qhov tseeb thiab qhov tseeb.
