Vim li cas electron microscopes tsis tuaj yeem hloov lub teeb microscopes
Lub tshuab hluav taws xob siv hluav taws xob siv lub hauv paus ntsiab lus ntawm electron optics, hloov lub teeb beam thiab optical lens nrog lub teeb hluav taws xob thiab lub lens electron, kom cov qauv zoo ntawm cov khoom siv tau pom nyob rau hauv qhov loj heev. Nws tau zoo dua li lub tshuab ntsuas qhov muag, tab sis lub tshuab ntsuas hluav taws xob yuav tsum tau ua haujlwm hauv lub tshuab nqus tsev, yog li nws nyuaj rau kev soj ntsuam cov kab mob nyob, thiab cov irradiation ntawm cov kab hluav taws xob kuj yuav ua rau cov kab mob lom irradiation puas tsuaj, yog li nws tsis tuaj yeem. tag nrho hloov kho qhov muag tsom iav, thiab lawv cov nqi tsis zoo ib yam, haum rau kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm kuj tsis zoo ib yam. Kuv vam tias kuv cov lus teb yuav pab tau koj.
Electron microscope tsis tuaj yeem hloov kho qhov muag tsom iav kom tiav rau cov laj thawj hauv qab no:
1. electronic microscope belongs rau optical microscope raws li qhov sib ntxiv ntawm CCD, tso saib lossis khoos phis tawj khoom siv, uas tuaj yeem tsuas yog hais tias yog lub tshuab tsom iav video, tag nrho cov txheej txheem imaging, CCD hloov ntawm tib neeg lub qhov muag. Vim hais tias cov duab yees duab, hluav taws xob magnification yog cuav amplification, thiab nyob rau hauv lub pixel, lub teeb rhiab heev nyhuv thiab lwm yam, nrog rau tib neeg lub qhov muag yog ib tug loj heev sib txawv, yog li ntawd nrog rau qhov pom kev microscope nyhuv yog loj heev sib txawv;
2. Muaj ib qho tseem ceeb tshaj plaws, CCD belongs rau lub dav hlau imaging, thiab tib neeg lub qhov muag, tshwj xeeb tshaj yog kev soj ntsuam binocular, yuav ua rau muaj kev nkag siab zoo ntawm peb-dimensional, uas yog ob qhov sib txawv ntawm qhov tob ntawm thaj tsam loj heev;
3. Electron microscope feem ntau yog qhia raws li electron scanning microscope, cov nyhuv microscope yuav zoo dua li cov nyhuv ntawm optical microscopy, tab sis vim yog tus nqi siab, yog li ob peb daim ntawv thov thiab kev lag luam.
