Electron microscopes yog siv txhawm rau tshawb xyuas ultrastructure ntawm ntau hom kab mob lom thiab inorganic nrog rau cov kab mob, cov hlwb, cov molecules loj, cov qauv biopsy, hlau, thiab crystals. Kev lag luam, electron microscopes feem ntau siv rau kev tswj kom zoo thiab tsis ua hauj lwm tsom xam.
Ua raws li qhov kev pom no, dab tsi yog electron microscope thiab nws siv rau dab tsi?
Electron microscopy (EM) yog cov txheej txheem kom tau txais cov duab daws teeb meem siab ntawm cov kab mob lom thiab tsis yog lom. Nws yog siv Hauv kev tshawb fawb biomedical los tshawb xyuas cov qauv nthuav dav ntawm cov ntaub so ntswg, hlwb, organelles thiab macromolecular complexes.
Ib sab saum toj no, dab tsi yog 3 hom electron microscopes? Muaj ntau ntau hom electron microscopes, suav nrog kis tau tus mob electron microscope (TEM), scanning electron microscope (SEM), thiab reflection electron microscope (REM.)
Kuj tseem yuav paub yog, vim li cas cov electrons siv hauv lub tshuab tsom iav?
Electron Microscope . Ib electron microscope tso cai rau peb pom ntawm cov nplai me me no. Electron microscopes ua haujlwm los ntawm kev siv ib qho hluav taws xob beam es tsis txhob pom lub teeb thiab ib qho hluav taws xob detector es tsis txhob ntawm peb ob lub qhov muag. Ib hluav taws xob beam tso cai rau peb pom ntawm cov nplai me me vim electrons kuj coj tau lub teeb.
Dab tsi yog qhov siab tshaj plaws ntawm electron microscope?
Qhov kev daws teeb meem ntawm electron microscopes yog 0,2nm siab kawg pab tau magnification ib electron microscope tuaj yeem muab yog li 1,000,000x.

Dab tsi yog qhov zoo ntawm electron microscope thiab lub teeb microscope?
Electron microscopes muaj qee qhov zoo ntawm optical microscopes: Qhov zoo tshaj plaws yog tias lawv muaj kev daws teeb meem siab dua thiab yog li tseem muaj peev xwm ua kom muaj qhov loj dua (txog 2 lab lub sijhawm). Lub teeb microscopes tuaj yeem pom qhov muaj txiaj ntsig zoo tsuas yog mus txog 1000-2000 zaug
Lub zog daws teeb meem ntawm electron microscope yog dab tsi?
Cov kab hluav taws xob hluav taws xob tau siv hauv tshuab hluav taws xob hluav taws xob los teeb pom cov qauv thiab yog li tsim cov duab. Txij li thaum lub wavelength ntawm f electrons yog 100,000 lub sij hawm luv dua li pom lub teeb lub electron microscopes muaj zog daws teeb meem ntau dua. Lawv tuaj yeem ua tiav qhov kev daws teeb meem ntawm 0.2nm thiab magnifications txog 2,000,000 x
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog lub hauv paus ntawm illumination nyob rau hauv electron microscope?
Nyob rau hauv kis tau tus mob electron microscope (TEM), lub hauv paus ntawm illumination yog ib tug beam ntawm electrons ntawm luv luv wavelength, tawm los ntawm ib tug tungsten filament nyob rau sab saum toj ntawm ib tug cylindrical kem ntawm txog 2 m siab. Tag nrho cov kab ke kho qhov muag ntawm lub tshuab microscope yog kaw hauv lub tshuab nqus tsev
Dab tsi yog confocal microscope siv rau?
Confocal microscopy, feem ntau confocal laser scanning microscopy (CLSM) los yog laser confocal scanning microscopy (LCSM), yog cov txheej txheem kho qhov muag kom nce kho qhov muag thiab qhov sib piv ntawm micrograph los ntawm kev siv lub spatial pinhole los thaiv lub teeb pom kev tawm. hauv kev tsim duab
