Kev piav qhia: Orientation yam yog tus lej uas nyob nruab nrab ntawm 0 thiab 1. Nws sawv cev rau feem ntawm kev sib tsoo nrog ib qho kev taw qhia uas tso cai rau cov tshuaj tiv thaiv tshwm sim. Cov tshuaj tiv thaiv tshwm sim thaum ob daim ntawv cog lus nyob rau hauv ze rau qhov zoo hydrogen kawg ntawm daim ntawv cog lus.
Ua li no, puas yog qhov kev taw qhia nyob ntawm qhov kub thiab txias?
Transition State Theory Pre-exponential Theory Lub empirical yam kuj rhiab heev rau kub . Raws li kub nce, molecules txav ceev; Raws li cov molecules txav nrawm dua, lawv feem ntau yuav sib tsoo thiab yog li cuam tshuam rau kev sib tsoo zaus, A.
Qhov thib ob, tus qauv kev sib tsoo yog dab tsi? Raws li cov kev sib tsoo qauv , cov tshuaj tiv thaiv tuaj yeem tshwm sim tsuas yog thaum cov reactant molecules, atoms, lossis ions sib tsoo nrog ntau tshaj li ib qho nyiaj ntawm kinetic zog thiab nyob rau hauv qhov kev taw qhia kom raug. Cov kev sib tsoo qauv piav qhia vim li cas, piv txwv li, feem ntau kev sib tsoo nruab nrab ntawm cov molecules tsis ua rau cov tshuaj tiv thaiv.
Yog li ntawd, kev taw qhia txhais li cas hauv chemistry?
Kev taw qhia hauv chemistry txhais tau tias uas thaum tshuaj tshuaj tiv thaiv kev sib tsoo ntawm cov atoms. Lub reactant molecules yuav tsum sib tsoo nrog dej siab kev taw qhia . Qhov tseeb kev taw qhia yog qhov uas ua kom muaj kev sib cuag ncaj qha ntawm lub atom koom nrog hauv kev tawg thiab tsim kev sib txuas.
Dab tsi yog postulates ntawm kev sib tsoo txoj kev xav?
Kev sib tsoo txoj kev xav yog nyob ntawm peb postulates : Cov tshuaj tiv thaiv nyob rau hauv cov roj theem yog vim lub kev sib tsoo ntawm cov reactant particles. A kev sib tsoo ua rau cov tshuaj tiv thaiv tsuas yog tias qee qhov pib lub zog dhau lawm. A kev sib tsoo ua rau cov tshuaj tiv thaiv tsuas yog tias cov kev sib tsoo particles raug taw qhia rau ib leeg.

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 ionic packing factor?
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
Dab tsi yog ply orientation?
Ply orientation. Lub ply orientation txhais cov txheeb ze orientation ntawm txhua ply. Nyob rau hauv cov pa thiab continuum plhaub layups Abaqus tej yaam num cov txheej txheem ply orientation mus rau saum npoo ntawm lub plhaub kom lub ply ib txwm kev taw qhia raws li zoo raws li lub plhaub ib txwm thiab layup stacking kev taw qhia
