Crystallography yog siv los ntawm cov kws tshawb fawb los ua tus yam ntxwv sib txawv. Nyob rau hauv ib lub crystals, qhov cuam tshuam ntawm crystalline kev npaj ntawm atoms yog feem ntau yooj yim pom macroscopically, vim hais tias cov duab ntawm ntuj crystals qhia txog cov qauv atomic.
Qhov tseem ceeb ntawm crystallography yog dab tsi?
Nws yuav tsis yog cov kws paub txog kev tshawb fawb tshaj plaws rau txhua tus, tab sis crystallography yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv kev pab kom nkag siab lub ntiaj teb nyob ib puag ncig peb. Crystallographers tuaj yeem ua haujlwm tawm cov qauv atomic ntawm yuav luag txhua yam. Thiab lawv siv qhov kev paub no los teb vim li cas txhua yam coj li lawv ua.
crystallography siv niaj hnub no li cas?
Hnub no, cov kws tshawb fawb siv lead ua kawm txog cov qauv atomic ntawm txhua yam khoom siv uas tuaj yeem tsim cov siv lead ua, los ntawm cov tshuaj yooj yim heev rau cov kab mob, cov protein lossis cov protein ntau ntau. Tab sis lawv kuj tshawb xyuas ntau yam ntawm lwm yam ntaub ntawv, xws li daim nyias nyias, kua muaju, fibers, iav, kua, gases thiab quasicrystals.
Koj piav qhia txog crystallography li cas?
Crystallography, ceg ntawm kev tshawb fawb uas deals nrog kev paub txog kev npaj thiab kev sib txuas ntawm atoms hauv crystalline solids thiab nrog cov qauv geometric ntawm siv lead ua lattices. Classically, cov khoom siv kho qhov muag ntawm cov khoom siv lead ua muaj txiaj ntsig hauv mineralogy thiab chemistry rau kev txheeb xyuas cov khoom.
Peb kawm dab tsicrystallography?
Crystallography yog kawm txog atomic thiab molecular qauv. Crystallographers xav paub yuav ua li cas cov atoms nyob rau hauv ib cov khoom yog teem nyob rau hauv thiaj li yuav nkag siab txog kev sib raug zoo ntawm atomic qauv thiab cov khoom ntawm cov ntaub ntawv. … Crystallography pib nrog kev kawm ntawm cov muaju, zoo li quartz.
