Yog hais tias txiav raws li kev ntxhib los mos, yuav muaj flaky dub me ntsis ntawm lub rooj tsavxwm, uas yog qhov phem heev. Txhawm rau kom muaj txiaj ntsig zoo nkauj, lub rooj tsavxwm tsuas tuaj yeem txiav kab rov tav, thiab cov khoom siv dub ntawm lub rooj tsavxwm yuav tsim cov kab txaij. American dawb granite uas tuaj yeem pom ntawm lub khw yog cov khoom ntawm kab rov tav txiav. Yog li ntawd, muaj longitudinal textures thiab micropores ntawm sab sauv thiab qis ntawm lub rooj tsavxwm. Cov pores yog nplua nuj thiab cov dej nqus phenomenon yog pom tseeb. Nws yog ib qho yooj yim heev rau pollute lub siv lead ua zoo ntawm lub pob zeb thaum ntub paving. Yog tias lub pob zeb tawg nrog rauj, nws yuav pom tias lub pob zeb ntawm ntu yog nyias thiab granular crystal. Qhov loj tshaj plaws pom crystal nto tsis ntau tshaj {{0}}.1mm, thiab feem ntau yog qis dua 0.1mm. Nws tuaj yeem pom meej nrog 20x magnifying iav. Xws li lub xeev siv lead ua yuav coj tau ob qhov txiaj ntsig: ua ntej, thaum ob peb lub teeb xim thiab cov pob zeb zoo nkauj sib xyaw ua ke, qhov saum npoo yuav tshwm dawb, thiab cov siv lead ua uas yuav tsum tau pob tshab thiab translucent yuav tshwm dawb vim qhov sib txawv thiab qhov sib txawv ntawm txhua lub siv lead ua; Qhov thib ob, thaum muaj dej los yog lwm yam ntaub ntawv pob tshab sau qhov sib txawv ntawm cov muaju, qhov tshwm sim ntawm refraction hloov, thiab lub pob zeb zoo li tsis dawb, tab sis cov xim translucent thiab semi-grey nyob rau hauv lub xeev ntub dej, tag nrho cov hniav zoo nkauj ntawm American dawb hemp. , uas yog qhov tshwm sim ntawm cov dej me me uas feem ntau paub hauv kev lag luam pob zeb.
