Cubic Close Packing. Qhov ntim ze tshaj plaws txhais tau hais tias cov atoms tau ntim ua ke kom ze li sai tauFCC chav tsev cell yog ua los ntawm plaub lub cubic kaw cov txheej (nyem los qhia cov chav tsev cell nrog txheej). Thawj txheej ntawm atoms ntim ua ke kom ze li sai tau.
Lub npe ntawm cubic kaw yog dab tsi?
Lawv hu ua face-centered cubic (FCC) (tseem hu ua cubic close packed) thiab hexagonal close-packed (HCP), raws li lawv symmetry.
cubic close packing class 12 yog dab tsi?
Cov qauv siv lead ua no hu ua cov qauv ntawm cubic close-packed (ccp) lossis face-centered cubic (fcc). Nyob rau hauv txhua tus ntawm lawv, txij li txhua tus sphere yog nyob rau hauv kev sib cuag nrog kaum ob spheres, tus lej sib koom yog 12. Hauv cov ntim kaw no, 74% ntawm qhov chaw nyob hauv cov khoom siv lead ua tau ntim.
3 seem yog dab tsi?
Lub lattice peb sab tej zaum yuav xav txog raws li tsim los ntawm ntau pawg ntawm cov dav hlau sib npaug Txhua txheej dav hlau muaj qhov taw qhia tshwj xeeb hauv qhov chaw. Qhov chaw txoj hauj lwm ntawm ib lub dav hlau crystallographic yog txiav txim los ntawm peb cov ntsiab lus lattice tsis dag ntawm tib txoj kab ncaj nraim.
Nyob rau hauv ib khub uas muaj txiaj ntsig zoo tshaj plaws yog tam sim no?
Yog li, cov lus teb raug yog (B) hcp thiab ccp cov qauv muaj cov khoom kaw zoo.

Nyob rau hauv cubic millimeter ntshav?
Nquag, ib lub cubic millimeter ntawm cov ntshav muaj ntawm 150,000 thiab 400,000 platelets. Yog tias tus lej poob qis dua li qhov no, cov ntshav uas tswj tsis tau yuav ua rau muaj kev pheej hmoo, qhov nce siab tshaj qhov txwv ntawm qhov ntau no qhia tau tias muaj kev pheej hmoo ntawm cov ntshav tsis tswj hwm .
Puas yog cubic zirconia tig ntsuab?
Puas yog cubic zirconia tig koj ntiv tes ntsuab? Tsis yog, nws tsis yog tias, tau kawg, koj xaiv qhov tsis zoo. Qee cov jewelers yuav sib tov lub cubic zirconia jewels nrog tooj dag, tooj liab, thiab xws li hlau. … Feem ntau, tab sis, cubic zirconia yog cov hlau zoo heev uas yuav tsis ua rau tawv nqaij .
