Cov yield zog feem ntau txhais los ntawm "0.2% offset zog". yield zog ntawm 0.2% offset yog txiav txim los ntawm kev nrhiav kev sib tshuam ntawm cov kev ntxhov siab -strain nkhaus nrog ib kab sib npaug mus rau qhov pib txoj kab nqes ntawm qhov nkhaus thiab uas cuam tshuam cov abscissa ntawm 0.2%.
Yog li ntawd, dab tsi yog vim li cas lub zog tawm los txhais tau tias yog 0.2% offset zog?
Cov yield zog yog txhais raws li qib ntawm kev ntxhov siab uas ua rau ib qho tshwj xeeb ntawm cov txheej txheem tas mus li. Qhov no txhais tau hais tias los ntawm lub sijhawm yield zog mus txog, cov khoom siv hauv paus twb tau yielded (undergone mus tas li) los ntawm txhais . Cov 0.2 % offset yield zog ( 0.2 % YOG, 0.2 % pov thawj kev ntxhov siab , rp0 ua.
Qhov thib ob, vim li cas lub zog tawm los tseem ceeb? Kev paub txog cov yield zog yog heev tseem ceeb thaum tsim cov khoom siv, vim nws feem ntau sawv cev rau qhov txwv siab tshaj ntawm cov khoom thauj uas tuaj yeem siv tau. Yield zog yog heev tseem ceeb rau kev tswj ntau cov ntaub ntawv 'cov txheej txheem ntau lawm, xws li forging, dov los yog nias.
Tom qab ntawd, lo lus nug yog, koj ua li cas txiav txim siab lub zog ntawm cov hlau?
Tensile xeem yog ib qho ntawm feem ntau kev xeem rau hlau . Cov xeem tau piav qhia los ntawm tus qauv EN 10 002. Cov xeem suav nrog straining a xeem daim los ntawm tensile quab yuam, feem ntau mus rau tawg, rau lub hom phiaj ntawm kev txiav txim tensile lub zog , yield zog , kev tshwm sim. ductility thiab txo qhov chaw.
Dab tsi yog tus qauv rau lub zog tensile?
Faib cov ntaub ntawv thov los ntawm qhov chaw hla ntu mus rau xam qhov siab tshaj plaws tensile kev nyuaj siab . Piv txwv li, ib tus tswv cuab nrog thaj tsam ntawm 2 hauv sq thiab qhov kev thov ntawm 1000 phaus muaj qhov siab tshaj plaws tensile kev nyuaj siab ntawm 500 phaus ib square inch (psi).

Yuav ua li cas koj thiaj paub tias muaj ib qho kev lav phib xaub ntawm ib qho khoom hauv Indiana?
Koj tuaj yeem siv peb cov kev pabcuam online lossis cov ntaub ntawv tshawb fawb ntawm Marion County Recorder's Office kom pom tias muaj kev lav phib xaub rau koj lub tsev. Yog tias muaj ntaub ntawv tsis txaus siab rau koj cov khoom, hu rau tus neeg tuav ntaub ntawv kom paub ntau ntxiv. Feem ntau, tus neeg tuav pov hwm yog tib tus neeg tuaj yeem tso cai tso cai
Yuav ua li cas koj xam bursting zog ntawm corrugated box?
Lub diaphragm yog nthuav dav siv hydraulics thiab raws li lub diaphragm nthuav, lub corrugated board bursts underpressure. Peb ntsuas lub zog tawg hauv Kilograms ib square centimeter. Qhov tshwm sim Bursting yog muab raws li ib txhiab npaug ntawm lub zog tawg, faib los ntawm grammage ntawm lub rooj tsavxwm

Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
