Kab qhov tsis xws luag , los yog dislocations, yog cov kab uas tag nrho cov kab ntawm atoms nyob rau hauv ib qho khoom yog teem anomalously. Qhov tshwm sim ntawm qhov tsis sib xws hauv qhov sib txawv yog qhov hnyav tshaj plaws raws kab hu ua kab ntawm dislocation. Kab qhov tsis xws luag tuaj yeem ua kom tsis muaj zog lossis ntxiv dag zog.
Ib yam li ntawd, dab tsi yog qhov kev tsis haum xeeb ntawm cov qauv?
A Planar Defect yog qhov tsis sib xws ntawm cov qauv siv lead ua zoo meej thoob plaws lub dav hlau. Txiaj Ntsig. Ib qho Kev Ciam Tebchaws yog ib qho dav dav planar defect uas cais cov cheeb tsam ntawm txawv crystalline orientation (piv txwv li nplej) nyob rau hauv ib tug polycrystalline khoom.
Ib yam li ntawd, dab tsi yog qhov tseem ceeb ntawm cov khoom siv lead ua? Muaj yooj yim chav kawm ntawm siv lead ua tsis xws luag : Point qhov tsis xws luag suav nrog lattice vacancy, self-interstitial atoms, hloov impurity atoms, thiab interstitial impurity atoms. kab tawm qhov tsis xws luag , uas yog pawg ntawm atoms nyob rau hauv tsis xwm yeem txoj hauj lwm. Tawm qhov tsis xws luag feem ntau hu ua dislocations.
Yog li ntawd, dab tsi yog qhov txawv ntawm cov ntsiab lus tsis xws luag?
Muaj peb yam tseem ceeb ntawm cov ntsiab lus tsis xws luag pom nyob rau hauv cov hlau: vacancy, interstitial defects thiab hloov pauv tsis xws luag
- Cov hauj lwm. Qhov chaw seem yog qhov tsis xws luag uas ib qho atom ploj ntawm nws qhov chaw ib txwm nyob hauv cov qauv siv lead ua (Fig.
- Interstitial defects.
- Kev hloov pauv tsis xws luag.
Dab tsi yog qhov defects?
Qhov Defects . Deg tsis xws luag yog cov ciam teb, lossis dav hlau, uas cais cov khoom siv rau hauv cheeb tsam, txhua cheeb tsam muaj cov qauv siv lead ua tib yam tab sis txawv kev taw qhia.

Dab tsi yog txhais los ntawm kev sib xyaw linear?
Los ntawm Wikipedia, dawb encyclopedia. Hauv kev ua lej, ib qho kev sib xyaw ua ke yog ib qho kev qhia tsim los ntawm cov ntsiab lus los ntawm kev sib faib txhua lub sij hawm los ntawm qhov tsis tu ncua thiab ntxiv cov txiaj ntsig (xws li linear ua ke ntawm x thiab y yuav yog ib qho kev qhia ntawm daim ntawv ax + los ntawm, qhov twg a thiab b yog tas li)
Dab tsi yog qhov tsis zoo linear correlation?
Ib qho kev sib raug zoo tsis zoo txhais tau hais tias muaj kev sib cuam tshuam ntawm ob qhov sib txawv - thaum ib qho kev sib txawv tsawg, lwm qhov nce ntxiv
Dab tsi yog linear tsim?
Cov txheej txheem linear lossis kev txhim kho yog ib qho uas qee yam hloov pauv lossis nce ncaj qha los ntawm ib theem mus rau lwm qhov, thiab muaj qhov pib thiab qhov xaus. Ib daim duab los yog daim ntawv muaj cov kab ncaj. cov ntse, linear designs ntawm Xya caug thiab yim caum
Dab tsi yog proportional linear kev sib raug zoo?
Proportional thiab linear functions yuav luag zoo tib yam nyob rau hauv daim ntawv. Qhov txawv tsuas yog qhov sib ntxiv ntawm qhov "b" tas mus li rau txoj haujlwm linear. Qhov tseeb, kev sib raug zoo ntawm kev sib raug zoo tsuas yog ib qho kev sib raug zoo uas b = 0, lossis muab tso rau lwm txoj hauv kev, qhov twg kab hla dhau los ntawm keeb kwm (0,0)
Dab tsi yog qhov teeb meem tsis yog linear?
Ib qho piv txwv ntawm qhov teeb meem tsis-linear isy=x^2. Yog tias koj pib nrog x = 1,2,3,4 qhov tshwm sim y = 1,4,9,16. Alinear teeb meem yog ib qho teeb meem uas daws tau los ntawm kev teeb tsa tsuas yog cov kab zauv sib npaug lossis cov kab sib npaug ntawm qhov sib npaug los daws. Ib qho kev qhia hauv cov variablesx1,, xn yog linear yog tias nws yog ntawm forma1x1 +
