Electron microscopes muaj qee qhov zoo ntawm optical microscopes: Qhov zoo tshaj plaws yog tias lawv muaj ntau dua daws teeb meem thiab yog li ntawd kuj tseem muaj peev xwm ntawm 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.

Ib yam li ntawd, qhov zoo ntawm electron microscope yog dab tsi?

Electron microscopes muaj ob qhov txiaj ntsig tseem ceeb thaum piv rau lub teeb microscopes: Lawv muaj ntau qhov kev nthuav dav ntau dua (tuaj yeem ntes cov qauv me me) Lawv muaj ntau dua. daws teeb meem (tuaj yeem muab cov duab meej thiab meej dua)

Tom qab, lo lus nug yog, dab tsi yog qhov zoo thiab qhov tsis zoo ntawm lub tshuab ntsuas hluav taws xob? Electron Microscope Disadvantages Lub ntsiab qhov tsis zoo yog cov nqi, qhov loj me, kev saib xyuas, kev cob qhia kws tshawb fawb thiab cov duab kos duab uas tshwm sim los ntawm kev npaj cov qauv. Hom no microscope yog ib qho loj, cumbersome, kim khoom, tsis tshua muaj siab rau kev co thiab sab nraud magnetic teb.

Tsis tas li ntawd, qhov zoo thiab qhov tsis zoo ntawm lub teeb tsom iav puas muaj qhov sib piv nrog lub tshuab ntsuas hluav taws xob?

Nqi / Muaj: Lub teeb microscopes pheej yig dua electron microscopes . Tswj cov duab tsim: Teeb ntawm iav lo ntsiab muag, kab teeb ntawm electrons tuaj yeem tsom siv electromagnets vim qhov tsis zoo ntawm tus nqi electrons . Kev daws teeb meem *: Electron microscopes muaj daws teeb meem ntau dua lub teeb microscopes.

Dab tsi yog qhov txawv ntawm electron microscope thiab lub teeb microscope?

Lub ntsiab qhov sib txawv ntawm lub teeb microscope thiab electron microscope yog tias ib electron microscope siv beams ntawm electrons kom nthuav cov duab ntawm ib yam khoom thaum lub teeb microscope siv rays ntawm pom teeb los tsim cov duab zoo heev ntawm thaj chaw me me ntawm cov ntaub ntawv lossis cov qauv lom neeg.
