Nyob rau hauv cov qauv cubic yooj yim muaj tsuas yog ib lub pas nrig ntawm txhua lub ces kaum ntawm lub voos xwmfab-zoo li lub cell. Lawv khij txoj hauj lwm ntawm ib qho atom, lossis tib pab pawg ntawm atoms, hu ua motif, uas tau rov ua dua hla lub lattice.
Puas yog piv txwv ntawm cov qauv cubic yooj yim?
Ntau qhov piv txwv ntawm cov lattices yooj yim tau paub (alpha - polonium yog ib qho ntawm ob peb paub yooj yim cubic lattices). Hauv qab no peb rov pom ib ntu ntawm cov kab laum yooj yim li nws "tiag" yog - nrog cov atoms kov ib leeg. Nco ntsoov cov channel uas tsim los ntawm kev sib koom ua ke ntawm interstitials.
Cubic unit cell yog dab tsi?
Qhov yooj yim cubic unit cell yog the simplest repeating unit in a simple cubic structure. Txhua lub ces kaum ntawm chav tsev cell yog txhais los ntawm ib tug lattice point uas muaj ib tug atom, ion, los yog molecule yuav pom nyob rau hauv lub siv lead ua. … Lub ntsej muag-centered cubic unit cell kuj pib nrog cov khoom zoo ib yam ntawm yim fab ntawm lub voos xwmfab.
cubic lattice hauv chemistry yog dab tsi?
Nyob rau hauv ib lub cubic lattice yooj yim, chav tsev cell uas rov qab nyob rau hauv tag nrho cov lus qhia yog ib lub voos xwmfab txhais los ntawm cov chaw ntawm yim atoms, raws li qhia hauv daim duab 10.49. Atoms ntawm cov ces kaum uas nyob ib sab ntawm chav tsev cell sib cuag ib leeg, yog li cov ntug ntev ntawm lub xovtooj ntawm no yog sib npaug rau ob lub atomic radii, los yog ib txoj kab uas hla atomic.
Tus lej sib koom ua ke hauv qhov yooj yim cubic lattice yog dab tsi?
Lub cubic yooj yim muaj kev sib koom testus naj npawb ntawm 6 thiab muaj 1 atom ib chav cell.
