Yas deformation yog qhov txawv txav mus tas li uas tshwm sim thaum cov khoom raug rau tensile, compressive, dabtsi yog khoov, lossis torsion stresses uas tshaj nws lub zog tawm los thiab ua rau nws elongate, compress, buckle, khoov, los yog twist.
Dab tsi yog qhov ua rau deformation?
Definition of Deformation
Nws feem ntau tshwm sim vim kev ntxhov siab uas tuaj yeem hais tias lub zog siv rau thaj chaw tshwj xeeb. Tsis tas li ntawd, muaj ntau yam laj thawj rau cov txheej txheem no tshwm sim. Piv txwv li, kev hloov ntawm qhov kub thiab txias, hloov ntawm lub ntiaj teb lub phaj sediment build-up thiab ntau yuav ua rau nws yooj yim.
Vim li cas cov yas deformation tshwm sim hauv cov hlau?
Plastic deformation ntawm cov hlau tshwm sim feem ntau los ntawm shearing: lattice dav hlau hauv cov khoom swb dhau ib leeg, tso cai rau macroscopic cov duab hloov yam tsis muaj kev cuam tshuam rau kev txiav txim thiab kev npaj ntawm atoms nyob rau hauv lub structure.
Plastic deformation tshwm sim qhov twg?
Plastic deformation nyob rau hauv daim ntawv ntawm plam tshwm sim nrog rau cov dav hlau uas kaw ntom nti, qhov twg lub zog xav tau rau kev txav txav txav tsawg. Slip hauv ib lub pob zeb siv lead ua mus txog thaum cov kab dislocation mus txog qhov kawg ntawm cov siv lead ua, qhov uas nws ua rau pom cov kauj ruam - yog li hu ua swb band.
Dab tsi ua rau plasticity?
Plasticity hauv cov hlau feem ntau yog tshwm sim los ntawm dislocations Hauv cov ntaub ntawv nkig xws li pob zeb lossis pob zeb, plasticity yog tshwm sim feem ntau los ntawm slippage ntawm microcracks. Cov ntaub ntawv yas nrog hardening yuav tsum tau nce siab kom ua rau cov yas deformation ntxiv.
Pom zoo:
Puas yog kev tshwm sim lossis kev tshwm sim?
Reveling, kuj spelled reveling, txhais tau tias muaj lub sij hawm zoo, los yog zoo siab rau ib yam dab tsi. Yog tias koj tawm mus ua kev zoo siab rau koj kawm tiav thiab koj haus dej haus, tog thiab muaj lub sijhawm zoo, qhov no yog qhov piv txwv ntawm thaum koj rov qab los .
Puas yog nws tshwm sim lossis tshwm sim?
Raws li lub npe qhov txawv ntawm qhov tshwm sim thiab qhov tshwm sim. yog happenchance is a coincidental happen while happenstance is (countable) a chance or random event or random events . Puas yog ib lo lus? Ib qho xwm txheej tsis tau xav txog:
Yuav ua li cas tshwm sim hauv kuv mob siab heev tshwm sim?
Thaum zaj yeeb yaj kiab tsis qhia meej raws li ib zaj dab neeg tseeb, nws yog tsim los ntawm cov xwm txheej hauv lub neej tiag tiag: yog, ntau tus neeg saib xyuas kev dag ntxias tau nyiag kev nplua nuj thiab kev ywj pheej ntawm suav tsis txheeb.
Yuav ua li cas cov yas siv los ua cov khoom noj uas tsis yog lo thiab vim li cas?
Teflon (Polytetrafluoroethylene) -Teflon yog tsim los ntawm cua sov tetrafluoroethene nrog cov dawb radical los yog ib qho sulphate catalyst ntawm kev kub ntxhov. Kev siv Teflon-Teflon yog siv los ua cov khoom siv uas tsis yog-stick txheej coated thiab ua cov roj foob thiab gaskets.
Cov siphons tshwm sim thiab tshwm sim nyob qhov twg?
Ntawm ob qhov qhib ntawm tom qab kawg ntawm clam. Qhov qhib qhov ntau dua yog cov siphon uas tshwm sim uas nqa dej mus rau hauv cov clam thiab qhov qhib qhov rooj ntau dua yog cov siphon uas tshwm sim uas cov khib nyiab & dej tawm . Cov kab mob dab tsi muaj tshwm sim thiab Excurrent siphon?
