Qhov sib txawv tseem ceeb ntawm hexagon thiab monoclinic unit cell yog tias hexagon unit cell muaj ob lub axes nrog qhov ntev sib npaug thiab ib lub axis nrog qhov ntev sib txawv whereas monoclinic unit cell muaj tag nrho peb axes nrog qhov ntev tsis sib xws.
Ib chav tsev cell yog lub hauv paus ntawm lub tshuab siv lead ua uas sawv cev rau cov qauv rov ua dua ntawm cov siv lead ua. Thiab chav tsev cell no yog ib lub thawv zoo li cov qauv. Yog li ntawd, nws zoo ib yam li tag nrho cov atoms nrog lawv spatial kev npaj. Ntxiv mus, lub thawv no muaj peb axes (a, b thiab c) thiab peb lub ces kaum (α, β thiab γ). Cov axes thiab cov ces kaum no muaj txiaj ntsig hauv kev txhais hom chav tsev cell.
Hexagon Unit Cell yog dab tsi
Hexagon unit cell los yog hexagonal unit cell yog lub hauv paus chav tsev uas sawv cev rau tag nrho cov atoms thiab lawv cov kev npaj nyob rau hauv ib tug hexagonal siv lead ua system. Lub hexagon chav cell no muaj ob lub axes nrog qhov ntev sib npaug, thiab cov axis seem muaj qhov ntev sib txawv ntawm ob lub axes.
Daim duab 01: Hexagonal Unit Cell
Lub axis no nrog qhov ntev sib txawv yog nyob rau ntawm ob lub axes. Ntawd yog, a=b≠c. Thaum xav txog cov ces kaum ntawm cov axes, lub kaum sab xis ntawm a thiab b axes (axes nrog qhov ntev sib npaug) yog 120◦ thaum lwm ob lub kaum sib npaug rau 90◦.
Monoclinic Unit Cell yog dab tsi?
Lub monoclinic chav cell yog lub hauv paus chav tsev uas sawv cev rau tag nrho cov atoms thiab lawv cov kev npaj nyob rau hauv ib tug monoclinic crystal system. Yog li ntawd, nyob rau hauv lub cell unit, tag nrho peb axes muaj tsis sib npaug lengths. Ntawd yog, a≠b≠c. Tsis tas li ntawd, hom chav tsev no muaj cov duab plaub.
Daim duab 02: Monoclinic Unit Cell
Lub hauv paus ntawm chav tsev cell no yog ib qho parallelogram (uas muaj ob khub ntawm ob sab sib luag). Lub kaum sab xis ntawm chav tsev cell yog α, γ, β qhov twg α=γ=90◦ thiab β≠90◦.
