Nyob rau xyoo tas los no, cov thev naus laus zis computed tomography tau siv rau ntau yam lag luam rau kev sim thiab tshuaj xyuas tsis puas tsuaj. Cov khoom lag luam computed tomography yog cov khoom siv tseem ceeb rau kev tswj hwm zoo thiab kev nyab xeeb. Lub hauv paus ntawm cov khoom no yog qhov tseem ceeb rau kev ua kom lawv ruaj khov thiab raug. Thaum nws los txog rau kev xaiv cov khoom siv rau lub hauv paus, granite feem ntau yog qhov kev xaiv nyiam dua hlau rau ntau yam laj thawj.
Ua ntej, granite yog ib lub pob zeb ntuj uas muaj nws qhov ceev, qhov tawv, thiab kev ruaj khov. Nws muaj qhov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv ntawm qhov kub thiab txias. Yog li ntawd, nws muaj kev ruaj khov zoo heev thiab muaj kev tiv thaiv siab rau kev hloov pauv thiab kev co. Qhov no ua rau nws zoo tagnrho rau cov khoom lag luam computed tomography, uas xav tau kev ruaj khov thiab raug.
Qhov sib txawv, cov hlau feem ntau nthuav dav thiab cog lus vim muaj kev hloov pauv thermal, uas ua rau lawv tsis haum rau cov khoom siv computer tomography hauv kev lag luam. Cov hauv paus hlau kuj tseem tuaj yeem cuam tshuam los ntawm cov yam ntxwv sab nraud xws li kev cuam tshuam electromagnetic, uas tuaj yeem ua rau muaj kev cuam tshuam thiab qhov yuam kev hauv kev nyeem cov khoom siv. Hauv qhov kev nkag siab no, granite yog qhov kev xaiv txhim khu kev qha dua rau kev ua kom ntseeg tau qhov tseeb thiab qhov tseeb ntawm cov khoom siv computer tomography hauv kev lag luam.
Tsis tas li ntawd xwb, granite tiv taus kev hnav thiab xeb, uas ua rau nws yog cov khoom siv ruaj khov dua li ntau cov hlau. Nws kuj tsis yog hlau nplaum, uas ua rau nws haum rau cov ntawv thov uas muaj teeb meem cuam tshuam los ntawm hlau nplaum. Tsis tas li ntawd xwb, granite muaj kev ruaj khov tshuaj lom neeg siab, uas txhais tau tias nws tsis cuam tshuam nrog feem ntau cov tshuaj, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev ua tib zoo thiab kev nyab xeeb.
Hais txog tus nqi, granite tuaj yeem kim dua li qee cov hlau, tab sis nws muaj nqis ntau rau cov nyiaj hauv lub sijhawm ntev. Nws lub zog ruaj khov, kev ruaj khov, thiab kev raug txhais tau tias nws yuav tsum tau saib xyuas thiab hloov pauv tsawg dua, uas tuaj yeem ua rau muaj kev txuag nyiaj ntau rau cov tuam txhab tsim khoom siv computer tomography hauv kev lag luam.
Xaus lus, thaum hlau yog ib yam khoom siv tau zoo rau ntau yam kev siv hauv kev lag luam, granite yog qhov kev xaiv zoo tshaj plaws rau cov hauv paus ntawm cov khoom siv computer tomography hauv kev lag luam. Nws qhov ceev, qhov nyuaj, kev ruaj khov, thiab kev tiv taus kev hnav, kev xeb, thiab kev tshuaj lom neeg ua rau nws yog ib yam khoom zoo tshaj plaws rau kev ua kom raug, qhov tseeb, thiab kev ruaj khov ntawm cov khoom no. Tsis tas li ntawd, granite muab tus nqi rau cov nyiaj hauv lub sijhawm ntev, ua rau nws yog kev nqis peev ntse rau cov tuam txhab tsim khoom siv computer tomography hauv kev lag luam.
