Dab tsi koj nyiam, lub tshuab tsom iav qhov muag lossis lub tshuab hluav taws xob hluav taws xob?
Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov ntawm electron microscope hauv thaj chaw ntawm microscopy yog qhov kev cia siab dav dav, ntau dua li qhov kho qhov muag tsom iav tau pom nws qhov tshwj xeeb superiority. Txawm li cas los xij, vim hais tias ntawm daim ntawv thov ntawm optical microscope thiab electron microscope technology thiab teb yog txawv, electron microscope thiab tsis tuaj yeem hloov kho qhov muag microscope.
Daim ntawv thov nyob rau hauv biology, optical microscope daws teeb meem yog deb tsawg tshaj li qhov hluav taws xob microscope, vim hais tias qhov kev daws teeb meem ntawm optical microscope los ntawm qhov kev txwv diffraction, yog li nws cov kev daws teeb meem tsis tuaj yeem tsawg dua ib nrab ntawm lub wavelength ntawm qhov teeb meem teeb meem. Qhov ntawd yog hais tias, yog hais tias qhov teeb meem ntawm 400nm, ces cov khoom soj ntsuam yuav tsis yog tsawg tshaj li 200nm, tab sis vim hais tias nws yuav ua tau tiag tiag-lub sij hawm, dynamic kev soj ntsuam, cov xwm txheej nyob rau hauv biology yog unparalleled, ib yam li nyob rau hauv lub teb ntawm biology yog. tsis yooj yim sua kom tawm ntawm fluorescence microscope thiab confocal thiab lwm yam optical microscopes. Thiab electron microscope vim yog siv cov kab hluav taws xob electron rau scanning imaging, nws cov kev daws teeb meem tau yooj yim mus txog qib nanometer, uas yog irreplaceable rau daim ntawv thov ntawm high-resolution imaging.
Hauv kev siv metallographic, qhov kev nthuav dav ntawm lub tshuab hluav taws xob hluav taws xob kuj tseem nyob deb dua li lub tshuab hluav taws xob kho qhov muag, qhov siab tshaj plaws ntawm lub tshuab hluav taws xob niaj hnub no tau ntau dua 3 lab lub sijhawm, thaum qhov siab tshaj plaws ntawm lub tshuab ntsuas qhov muag yog li 2,{{2 } } zaug, yog li lub tshuab ntsuas hluav taws xob muaj peev xwm ncaj qha saib cov atoms ntawm qee cov hlau hnyav thiab cov muaju hauv cov atom ntawm cov txheej txheem ntawm cov dots.
