Ionic packing factor (IPF), zoo ib yam txhais ntawm APF. Tib txoj cai raws li cov hlau w / hwm rau siv lead ua symmetry. Yuav ua li cas yog ions los ntawm cov qauv siv lead ua? Qauv: CsCl hom Bravais lattice: yooj yim cubic Ions /unit cell: 1 Cs + 1 Cl ? Cl? Cs + 7 (tsis yog atoms) 1.
Ib yam li ntawd, txhais li cas los ntawm atomic packing factor?
Los ntawm Wikipedia, dawb encyclopedia. Hauv crystallography, atomic packing factor (APF), ntim efficiency los yog packing feem yog cov feem ntawm ntim nyob rau hauv ib tug siv lead ua qauv uas yog nyob los ntawm constituent hais. Nws yog ib qho dimensionless kom muaj nuj nqis thiab ib txwm tsawg dua kev sib sau.
Ib tug kuj yuav nug, dab tsi yog ntim cov feem hauv physics? Kev txhais ntawm packing feem .: ib qho kev ntsuas ntawm qhov poob los yog nce ntawm tag nrho cov huab hwm coj nyob rau hauv ib pawg ntawm nucleons thaum lawv raug coj los ua ib tug atomic nucleus: qhov ratio multiplied los ntawm 10, 000 ntawm cov loj defect rau cov huab hwm coj.
Tsis tas li ntawd, vim li cas atomic packing factor tseem ceeb?
Ib lub dav hlau plam nrog qhov siab tshaj plaws atomic Qhov ntom yog nyiam rau deformation vim qhov kev ncua deb ntawm atoms me me heev uas dislocation txav los ntawm kev siv qis dua yog yooj yim dua thiab siab dua atomic packing factor yog ib qho qhia txog qhov yooj yim ntawm deformation.
Dab tsi yog packing feem nyob rau hauv solid state?
Atomic packing feem Feem ntau muab peb lub tswv yim txog kev npaj ntawm atoms / ions hauv cov khoom khib nyiab . Nws yuav muab qhov ua tau zoo uas qhov chaw muaj nyob tau sau los ntawm atoms. Packing feem txhais tau tias yog qhov piv ntawm ntim ntawm atoms nyob hauv chav tsev cell mus rau qhov ntim ntawm chav tsev cell.

Ceev Yus Tswj yam Lub ceev nyob yam yog yam tseem ceeb uas nws los nyob rau hauv lub me me los yog txoj kev loj hlob ntawm cov pejxeem sib txawv nrog cov pejxeem ceev. Muaj ntau ntau yam ntawm qhov ntom ntom ntawm qhov txwv tsis pub muaj xws li; muaj zaub mov, predation, kab mob, thiab tsiv teb tsaws
Radiation weighting factor yog dab tsi?
Qhov ntsuas hluav taws xob hnyav yog qhov kwv yees ntawm qhov ua tau zoo ntawm ib chav tsev ntawm qhov muab hluav taws xob cuam tshuam rau tus qauv qis-LET. Gy (joule / kg) tuaj yeem siv rau txhua hom hluav taws xob. Gy tsis piav txog cov teebmeem lom ntawm cov hluav taws xob sib txawv
Dab tsi yog txhais los ntawm steric factor?
Kuj hu ua qhov tshwm sim qhov tshwm sim, qhov steric tau txhais tias yog qhov piv ntawm qhov kev sim ntawm tus nqi tas li thiab qhov kwv yees los ntawm kev sib tsoo txoj kev xav. Nws tseem tuaj yeem txhais tau tias yog qhov piv ntawm qhov ua ntej exponential thiab qhov sib tsoo zaus, thiab nws feem ntau tsawg dua kev sib sau
Dab tsi yog qhov null factor?
Txoj Cai Null Factor Yog tias qhov khoom ntawm ob tus lej yog xoom, ces ib lossis ob tus lej yog xoom. Ntawd yog, yog tias ab = 0, ces a = 0 lossis b = 0 (uas suav nrog qhov ua tau tias a = b = 0). Qhov no hu ua Null Factor Law; thiab peb siv nws ntau zaus los daws qhov sib npaug ntawm plaub fab
Dab tsi yog atomic packing factor ntawm cov qauv siv lead ua?
Atomic packing factor tseem hu ua packing efficiency ntawm crystal. Nws txhais tau tias yog qhov ntim tau los ntawm kev sib txuas tag nrho cov atoms ntawm ib lub cell hauv kev sib piv rau tag nrho cov ntim ntawm ib chav tsev cell, piv txwv li nws yog ib feem ntawm lub ntim nyob los ntawm tag nrho cov atoms nyob rau hauv ib chav tsev cell mus rau tag nrho cov ntim ntawm ib chav tsev cell
