Vim li cas qhov kev daws teeb meem ntawm lub tshuab ntsuas hluav taws xob yog siab dua li ntawm lub teeb tsom iav?
Lub magnification ntawm optical microscope yog me dua li ntawm electron microscope. Lub tshuab ntsuas qhov muag tsuas tuaj yeem soj ntsuam cov qauv microstructures, xws li cov hlwb thiab chloroplasts, thaum lub tshuab hluav taws xob tshuab hluav taws xob tuaj yeem soj ntsuam cov qauv submicroscopic, uas yog, cov qauv ntawm organelles, kab mob, kab mob, thiab lwm yam.
Lub tshuab hluav taws xob tshuab hluav taws xob ua haujlwm ua kom nrawm thiab muaj zog electron beam mus rau cov qauv nyias nyias, thiab cov electrons sib tsoo nrog cov atoms hauv cov qauv los hloov lawv cov kev taw qhia, yog li tsim cov khoom tawg tawg. Qhov luaj li cas ntawm lub kaum sab xis yog cuam tshuam nrog qhov ntom thiab tuab ntawm cov qauv, yog li cov duab sib txawv ntawm qhov ci thiab qhov tsaus ntuj tuaj yeem tsim tau, thiab cov duab yuav raug tso tawm ntawm cov khoom siv duab (xws li cov ntxaij vab tshaus fluorescent, zaj duab xis, thiab cov khoom sib txuas photosensitive) tom qab zooming thiab tsom.
Vim yog luv luv de Broglie wavelength ntawm electron, qhov kev daws teeb meem ntawm kis tau tus mob electron microscope yog ntau dua li ntawm lub optical microscope, uas muaj peev xwm ncav cuag 0.1-0.2nm, thiab lub magnification yog kaum txhiab mus rau lab lub sij hawm. Yog li ntawd, kev siv cov tshuab hluav taws xob xa hluav taws xob tuaj yeem siv los soj ntsuam cov qauv zoo ntawm cov qauv, txawm tias cov qauv ntawm tsuas yog ib kem ntawm atoms, uas yog kaum tawm txhiab zaus me dua li cov qauv me tshaj plaws uas tuaj yeem pom los ntawm optical microscopy. TEM yog ib qho tseem ceeb analytical txoj kev nyob rau hauv ntau yam scientific teb hais txog physics thiab biology, xws li kev tshawb fawb mob cancer, virology, ntaub ntawv science, raws li zoo raws li nanotechnology, semiconductor kev tshawb fawb, thiab lwm yam.
