Kev lag luam suav nrog microelectronics, semiconductors, cov khoom siv kho mob, kev tsim khoom dav dav, kev tuav pov hwm thiab kev hais plaub ntug, thiab kev ua zaub mov, txhua tus siv cov tshuab ntsuas hluav taws xob hauv tshuab hluav taws xob ua ib txoj hauv kev los tshuaj xyuas qhov sib xyaw ntawm qhov chaw. Cheebtsam thiab cov khoom.
Vim li cas thiaj siv tshuaj ntsuam xyuas electron microscopes?
Taw qhia. Lub tshuab ntsuas hluav taws xob siv hluav taws xob siv lubua kom pom tseeb ntawm cov hluav taws xob los qhia cov ncauj lus kom ntxaws ntawm tus qauv thiab muab cov ntaub ntawv hais txog nws cov qauv peb sab. Nws kuj muaj qhov zoo tshwj xeeb ntawm kev muab qhov tob tob ntawm thaj teb.
SEM scanning electron microscope siv rau dab tsi?
A scanning electron microscope (SEM) scans lub tsom teeb hluav taws xob hla saum npoo los tsim cov duab. Cov electrons hauv beam cuam tshuam nrog cov qauv, ua ntau yam teeb liab uas siv tau kom tau txais cov ntaub ntawv hais txog qhov chaw saum npoo av thiab muaj pes tsawg leeg.
Cov kws kho mob puas siv electron microscopes?
Txawm hais tias muaj ntau ntau hom electron microscopes (xws li, high-voltage, scanning, analytic), lub kis tau tus mob electron microscope feem ntau yog siv rau kev kuaj kab mob(thiab yog hom electron microscope raug xa mus rau thoob plaws hauv tshooj no, tshwj tsis yog sau ua lwm yam).
Yuav ua li cas kev lag luam siv electron microscope?
Lwm kev lag luam uas feem ntau siv hluav taws xobmicroscopes ua ib feem ntawm lawv cov txheej txheem tsim khoom suav nrog aeronautics, automotive, khaub ncaws, thiab kev lag luam tshuaj. Electron microscopy kuj tseem tuaj yeem siv rau hauv kev lag luam tsis ua haujlwm tsom xam thiab kev tswj xyuas cov kev lag luam sib txawv.

Dab tsi yog qhov txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob?
Gramophone: Txhua lub suab kaw suab, lossis cov cuab yeej ua si yav dhau los-cov suab kaw, tshwj xeeb tshaj yog tias nws siv lub tiaj tiaj tiaj. Phonograph: Txhua lub suab kaw suab, lossis cov cuab yeej siv rau kev ua si cov suab uas tau kaw dhau los, tshwj xeeb tshaj yog tias nws siv lub tog raj kheej tig.
Puas yog lub tshuab hluav taws xob xav tau lub tshuab hluav taws xob?
Diesels tsis xav tau lawv - pob tseg li qub / tshuab tawm li qub yog tsim los rau qhov chaw nruab nrab ntawm lub turbo thiab lub throttle. Nyob rau hauv ib tug petrol engine, ntawm siab boost, thaum koj snap lub throttle kaw lub turbo tseem tig.
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.
Puas yog lub tshuab hluav taws xob puas muaj lub tshuab hluav taws xob?
Vim li cas lub tshuab hluav taws xob sab hauv combustion yuav tsum tsis muaj lub tshuab hluav taws xob los ua kom cov roj tsis zoo li roj av? Spark plugs yog siv nyob rau hauv cov roj cav mus ignite cov pa roj sib tov whereas nyob rau hauv diesel engines lub xub ntiag ntawm lub txim plugs yog tsis tsim nyog.
