Vim li cas electron microscopes tsim cov duab dub thiab dawb? Qhov laj thawj yog qhov yooj yim zoo nkauj: xim yog cov cuab yeej ntawm lub teeb (piv txwv li, photons), thiab txij li lub tshuab ntsuas hluav taws xob siv ib lub teeb hluav taws xob los duab cov qauv, tsis muaj cov ntaub ntawv xim sau tseg.
Electron microscopes puas pom xim?
Ib txoj hauv kev tshiab ntawm colourizing electron microscope imagery yuav ua rau nws yooj yim dua rau microbiologists pom cov molecules tsis pom. Xav txog qhov twg Waldo phau ntawv tsis muaj dab tsi tab sis cov duab dub thiab dawb.
Cov xim dab tsi yog lub tshuab tsom iav?
Cov kev siv ntau tshaj plaws thiab cov xim sib xws yog raws li hauv qab no: dub txhais tau tias 1-1.5x, brown txhais tau tias 2x lossis 2.5x, liab txhais tau tias 4x lossis 5x, daj txhais tau tias 10x, ntsuab txhais tau tias 16x lossis 20x, turquoise txhais tau tias 25x lossis 32x, lub teeb xiav txhais tau tias 40x lossis 50x, ci xiav txhais tau tias 60x lossis 63x thiab dawb lossis dawb txhais tau tias 100-250x.
Electron microscopes puas pom cov kab mob?
Viruses me heev thiab feem ntau ntawm lawv tuaj yeem pom tsuas yog los ntawm TEM (kev xa hluav taws xob hluav taws xob).
Vim li cas electron microscopes thiaj li kim?
A scanning electron microscope yuav tsum tau ua haujlwm hauv lub tshuab nqus tsev, thiab qhov ntawd ntxiv cov nqi tseem ceeb. Tsis tas li ntawd, nws cov lo ntsiab muag yog cov zoo li cov hlau nplaum sib nqus thiab cov no tsis yooj yim replicated nrog loj tsim txoj kev.
