Differential Aeration Corrosion tshwm sim thaum muaj qhov tsis sib xws ntawm cov pa oxygen rau thaj chaw ntawm tib cov hlau tivthaivNws yog hom electrochemical corrosion uas cuam tshuam rau cov hlau xws li hlau thiab hlau.. … Qhov no yog qhov uas cov oxidation tshwm sim, cov khoom siv corrosion thiab ib lub qhov ua rau cov hlau tsis muaj zog.
Dab tsi yog qhov txawv ntawm aeration corrosion piv txwv?
Corrosion vim ua ntej oxidation thiab txhuam. Qhov sib txawv aeration tshwm sim thaum ib feem ntawm ib daim hlau nyob twj ywm ntub ntev(thaum tsau rau ntawm phab ntsa lossis rau txoj kev pav, piv txwv li) thaum cov khoom seem qhuav. Tom qab ntawd qhov corrosion tshwm sim hauv thaj tsam nruab nrab ntawm ob sab (Daim duab 13.30).
Ntawm qhov twg ntawm cov hlau sib txawv aeration ntawm corrosion yuav tshwm sim?
Hauv qhov sib txawv aeration corrosion, cheeb tsam nrog cov pa oxygen ntau dua dhau los ua cov cathodethaj chaw uas muaj cov pa oxygen qis dua ua cov anode. Yog li ntawd, qhov seem ntawm cov hlau uas muaj cov pa oxygen tsawg dua yog qhov feem cuam tshuam rau corrosion.
Qib ntawm aeration cuam tshuam rau corrosion li cas?
Nyob rau hauv cov ntsiab lus, aeration accelerates anodic corrosion txheej txheem… Tsis tas li ntawd, qhov tseeb corrosion puas tuaj yeem ua phem dua vim tias muaj cov pa oxygen ntau ntxiv, kev txhim kho hauv cheeb tsam tuaj yeem nce tus nqi ntawm kev tawm tsam los ntawm Lwm qhov kev txiav txim ntawm qhov loj me uas tuaj yeem ua rau tag nrho 100 npaug ntawm qhov nkag mus.
Dab tsi yog qhov sib txawv aeration cell?
Ib qhov sib txawv aeration ntawm tes ua rau xeb ntawm cov hlau vim yog kev tsim cov pa oxygen concentration cell, uas yog tshwm sim los ntawm huab cua tsis sib xws ntawm cov hlau. … Ib lub xov tooj cua sib txawv tseem hu ua oxygen concentration cell.

Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Pfaffian qhov sib txawv qhov sib txawv yog dab tsi?
Daim ntawv dav dav ntawm Pfaffian equations hauv ob qhov sib txawv x thiab y yog P dx + Qdy=0, qhov twg P=P(x, y) thiab Q=Q(x, y) yog cov haujlwm ntawm x thiab y. … Yog hais tias peb tuaj yeem nrhiav cov haujlwm f=f (x, y) thiab g=g(x, y) xws li ω=gdf, ces ω=0 tuaj yeem raug txo kom df=0 nrog kev daws f(x, y)=c (c yog qhov tsis tu ncua) .
Dab tsi yog qhov sib txawv ntawm qhov sib txawv?
Nyob rau hauv nplooj ntawv no koj tuaj yeem tshawb pom 12 lub ntsiab lus, cov lus sib piv, cov lus qhia tsis zoo, thiab cov lus hais txog qhov tsis sib xws, xws li: antithesis , contraposition contraposition Nyob rau hauv ib txwm logic, contraposition yog ib daim ntawv ntawm tam sim no inference nyob rau hauv uas ib tug proposition yog inferred los ntawm lwm tus thiab qhov twg tus qub muaj rau nws cov ntsiab lus contradictory ntawm tus thawj logical proposition tus predicate
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
Nyob rau hauv fraunhoffer qhov sib txawv ntawm qhov sib txawv wavefront yog?
Nyob rau hauv qhov sib txawv no qhov xwm txheej thiab qhov sib txawv yoj pem hauv ntej yog spherical lossis cylindrical (b) Fraunhoffer diffraction: Hauv fraunhoffer diffraction, lub teeb qhov chaw thiab qhov taw qhia kev soj ntsuam nyob ntawm qhov kev ncua deb ntawm lub teeb meem.
