Cov khoom siv hluav taws xob yuav tsum tau sim ua ntej lawv ua tiav rau hauv cov khoom tiav. … Thaum cov tuam txhab ua lag luam ua cov txheej txheem tswj xyuas thiab siv cov qauv sib txawv kom ntseeg tau tias lawv cov khoom tsim los rau cov lus qhia tshwj xeeb, yuav xav tau kev sim ntau ntxiv kom ntseeg tau tias muaj kev ntseeg siab thiab ua tau zoo thawj zaug.
Dab tsi yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob?
Cov khoom siv hluav taws xob yogtseem ceeb ntawm kev tsim cov khoom siv hluav taws xob. Qhov zoo tshaj plaws ntawm cov khoom siv hauv cov txheej txheem tsim tau yooj yim txiav txim siab koj lub neej yav tom ntej thiab kev loj hlob hauv kev lag luam. Cov khoom zoo kawg nkaus txhim kho qhov zoo ntawm cov khoom kawg kom zoo raws li nws ua tau ntev.
Kev ntsuas qhov zoo yog dab tsi?
Kev ntsuas yuav tsum suav nrog kev muab qhab nia, kev kawm, thiab kev txhawb siab rau koj cov tub ntxhais kawm. Txoj kev ntsuam xyuas tau tsim zoo muab cov ntaub ntawv tseem ceeb ntawm cov tub ntxhais kawm kev kawm. Lawv qhia peb tias cov menyuam kawm ntawv kawm tau dab tsi, lawv kawm tau zoo npaum li cas, thiab lawv nyuaj rau qhov twg.
Vim li cas peb yuav tsum sim cov khoom siv hluav taws xob thaum peb ua qhov kev xeem?
Kev ntsuas kev nyab xeeb yog xav tau ntawm qhov chaw tsim khoom, ua ntej cov khoom muaj rau cov neeg siv kawg. Cov neeg tsim khoom ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yuav tsum xyuas kom meej tias tsis muaj cov hluav taws xob txaus ntshai lossis cov khoom siv hluav taws xob nkag mus rau cov neeg siv. Lawv yuav tsum tausim lawv cov khoom txhawm rau txiav txim siab seb lawv puas ua tau raws qib kev nyab xeeb yam tsawg kawg.
Vim li cas peb thiaj xav tau kev xeem?
Lawv siv los txiav txim seb cov tub ntxhais kawm tau kawm qhov lawv xav tau kawm los yog qib lossis qib uas cov tub ntxhais kawmtau kawm cov ntaub ntawv. Tej zaum lawv yuav raug siv los ntsuas kev kawm tau zoo thiab kev ua tau zoo thiab ntsuas qhov ua tau zoo ntawm cov kev kawm.

Puas yog kev siv hluav taws xob siv hluav taws xob?
Usability engineering yog kev qhuab qhia uas tsom mus rau kev txhim kho kev siv tau ntawm kev sib tham sib. Nws rub tawm cov kev xav los ntawm kev tshawb fawb hauv computer thiab kev puas siab puas ntsws los txhais cov teeb meem uas tshwm sim thaum siv cov kab ke.
Hauv cov khoom siv hluav taws xob tsim hluav taws xob?
Nyob hauv cov khoom siv hluav taws xob tsim hluav taws xob, xws li hlau, hluav taws xob rhaub, boiler, toaster thiab lwm yam, ib qho hlau xws li Nichrome Nichrome Nichrome (tseem hu ua NiCr, nickel-chromium lossis chromium-nickel) yog ib tsev neeg ntawm cov alloys ntawm npib tsib xee, chromium, thiab feem ntau hlau (thiab tejzaum nws muaj lwm yam) feem ntau siv raws li cov hlau tsis kam, cov khoom cua sov hauv cov khoom xws li toasters thiab qhov chaw tso cua sov, hauv qee qhov
Puas yog cov hluav taws xob muaj hluav taws xob zoo?
Ntau yam tseem ceeb, lossis subatomic, cov khoom ntawm cov khoom muaj cov khoom siv hluav taws xob. Piv txwv li, electrons muaj tus nqi tsis zoothiab protons muaj tus nqi zoo, tab sis neutrons muaj pes tsawg tus nqi. Yuav ua li cas them electrons e nqa?
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
