Electron microscopy muaj ntau qhov zoo. Cov no suav nrog: Kev nthuav dav thiab kev daws teeb meem siab dua - raws li cov khoom siv hluav taws xob ntau dua li siv lub teeb nthwv dej, nws tuaj yeem siv los txheeb xyuas cov qauv uas tsis tuaj yeem pom.
Vim li cas koj thiaj siv lub tshuab ntsuas hluav taws xob?
Electron microscopes yog siv los tshawb xyuas cov txheej txheem ntawm ntau yam ntawm cov kab mob lom neeg thiab cov kab mob tsis muaj kab mob suav nrog cov kab mob, cov hlwb, cov molecules loj, kuaj biopsy, hlau, thiab muaju. Industrially, electron microscopes feem ntau yog siv rau kev tswj kom zoo thiab tsis ua hauj lwm tsom xam.
Vim li cas electron micrograph zoo dua lub teeb?
Electrons muaj ntau lub wavelength luv dua li pom lub teeb, thiab qhov no tso cai rau cov tshuab hluav taws xob hluav taws xob los tsim cov duab daws teeb meem dua li cov qauv teeb pom kev zoo. … Ntau yam nthuav dav tuaj yeem pom nyob rau hauv scanning electron micrograph.
Dab tsi yog qhov zoo ntawm scanning electron microscope?
Qhov zoo ntawm Scanning Electron Microscope suav nrog nws qhov dav-array ntawm daim ntawv thov, cov ncauj lus kom ntxaws txog peb sab thiab qhov chaw nyob thiab cov ntaub ntawv muaj ntau yam tau khaws los ntawm cov khoom sib txawv.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm lub teeb kis tau tus mob thiab tshuaj ntsuam xyuas electron microscope?
Qhov zoo: Hauv lub teeb microscopes, lub teeb beam tsis tua lub cell. Electron microscopes muaj txiaj ntsig zoo hauv kev saib cov ntsiab lus tsis sib xws ntawm cov qauv thiab muaj kev daws teeb meem siab. Disadvantage: Lub teeb microscopes muaj lub zog daws teeb meem tsawgElectron microscopes raug nqi thiab yuav tsum tua cov qauv.
