Peb muaj 12/4 +1=4 txoj haujlwm hauv ib chav cell. Ntawm no peb muaj qhov chaw octahedral hauv bcc lattice. Peb muaj 12/4 + 6/2= 6 txoj haujlwm ib chav cell.
Muaj pes tsawg qhov chaw octahedral nyob hauv BCC?
A BCC muaj 6 octahedral qhov thiab 12 tetrahedral qhov.
Puas muaj octahedral voids hauv BCC?
Yog li, bcc muaj 2 atoms, ces tus lej ntawm octahedral voids yuav yog 2 thiab tag nrho cov tetrahedral voids yuav yog=2 x 2=4. Nco tseg: Tus tag nrho cov octahedral voids hauv fcc (lub ntsej muag-centered cubic) yuav yog 4 thiab tag nrho cov tetrahedral voids yuav yog 8 vim hais tias tus naj npawb ntawm atoms nyob rau hauv fcc yog 4.
Muaj pes tsawg octahedral interstices muaj nyob rau hauv fcc?
Muaj 8 qhov tetrahedral thiab 4 octahedral qhov hauv fcc chav cell.
Muaj pes tsawg qhov chaw tetrahedral nyob hauv BCC?
Muaj plaub qhov chaw tetrahedral ntawm txhua lub rau ntawm BCC lub ntsej muag (½, ¼, 0).
