Granite yog ib lub pob zeb ntuj uas muaj ntau yam zoo uas ua rau nws tsim nyog rau kev siv computer tomography (CT) hauv kev lag luam. Cov khoom siv granite muab cov txiaj ntsig zoo hauv kev ruaj khov, raug, ruaj khov, thiab pheej yig.
Kev ruaj khov yog ib qho tseem ceeb tshaj plaws hauv cov khoom lag luam CT. Granite paub txog nws qhov kev ruaj khov siab, cov coefficient qis ntawm thermal expansion, thiab cov khoom zoo heev rau kev co. Qhov no ua rau nws zoo tagnrho rau kev siv hauv thaj chaw uas muaj kev co siab lossis kev hloov pauv kub, xws li hauv cov chaw kuaj engineering lossis cov chaw tsim khoom. Cov khoom siv granite pab kom ntseeg tau tias CT scanner tsim cov txiaj ntsig raug, tsis muaj kev cuam tshuam lossis kev cuam tshuam los ntawm cov yam sab nraud.
Lwm qhov txiaj ntsig ntawm cov khoom granite yog lawv qhov tseeb. Granite yog cov khoom siv ntom ntom heev, uas muab kev ruaj khov thiab kev ruaj khov zoo heev. Qhov no txhais tau tias nws tsis tshua muaj kev cuam tshuam rau kev hloov pauv lossis kev sib txhuam dhau sijhawm dua li lwm cov ntaub ntawv, xws li txhuas lossis yas. Yog li ntawd, cov khoom granite tuaj yeem muab cov qib siab ntawm kev raug thiab qhov tseeb uas xav tau rau kev luam theej duab CT ntxaws. Qhov no tseem ceeb heev thaum ua haujlwm nrog cov khoom me me lossis cov khoom me me, qhov twg txawm tias qhov yuam kev me me tuaj yeem muaj kev cuam tshuam loj rau qhov tshwm sim kawg.
Kev ruaj khov yog lwm qhov zoo tseem ceeb ntawm cov khoom granite. Granite yog cov khoom siv tawv, ruaj khov uas tuaj yeem tiv taus kev siv hnyav thiab kev tuav tsis zoo. Tsis zoo li lwm cov ntaub ntawv uas tuaj yeem ua rau tawg lossis tawg dhau sijhawm, cov khoom granite tiv taus kev hnav thiab tsim kua muag, thiab tuaj yeem kav ntev ntau xyoo nrog kev saib xyuas kom zoo. Qhov no ua rau lawv yog qhov kev xaiv txhim khu kev qha thiab tsis tas yuav saib xyuas rau cov khoom lag luam CT, txo qhov xav tau kev kho lossis hloov pauv ntau zaus.
Kev siv nyiaj tsim nyog kuj yog qhov tseem ceeb thaum xaiv cov khoom siv rau cov khoom lag luam CT. Txawm hais tias granite yuav muaj tus nqi pib siab dua li lwm cov ntaub ntawv, nws muab kev txuag nyiaj mus sij hawm ntev. Qhov no yog vim tias cov khoom granite xav tau kev saib xyuas tsawg dua li lwm cov ntaub ntawv, thiab tsis tas yuav kho lossis hloov pauv. Tsis tas li ntawd, granite muaj qhov cuam tshuam tsawg rau ib puag ncig, ua rau nws yog cov khoom siv ruaj khov thiab zoo rau ib puag ncig.
Zuag qhia tag nrho, qhov zoo ntawm cov khoom granite rau cov khoom lag luam CT yog qhov tseeb. Lawv muab kev ruaj khov, qhov tseeb, kev ruaj khov, thiab kev siv nyiaj tsim nyog, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv cov chaw kuaj engineering, cov chaw tsim khoom, thiab lwm qhov chaw ua haujlwm uas qhov tseeb thiab kev ntseeg tau yog qhov tseem ceeb. Txawm hais tias koj tab tom nrhiav lub tshuab luam theej CT zoo rau koj lub lag luam lossis tus neeg muab khoom txhim khu kev qha, kev xaiv cov khoom granite yog kev nqis peev ntse uas yuav them rov qab rau lub sijhawm ntev.
