Hauv qab cov qauv hauv qab no tau pom nyob rau hauv tib lub xov tooj ntawm tes, sab laug saib nrog lub teeb pom kev zoo, thiab sab xis nrog lub tshuab hluav taws xob xa hluav taws xob. Mitochondria pom nrog lub teeb microscope tab sis tsis tuaj yeem pom hauv kev nthuav dav. Ribosomes tsuas yog pom nrog lub tshuab ntsuas hluav taws xob.
Tom qab ntawd, ib tus tuaj yeem nug, vim li cas qee cov qauv ntawm tes tuaj yeem pom nrog lub tshuab ntsuas hluav taws xob tab sis tsis nrog lub teeb pom kev zoo?
Electron microscopes siv beam electrons es tsis txhob beams los yog rays ntawm teeb . Nyob hlwb tsis tuaj yeem soj ntsuam siv ib electron microscope vim cov qauv yog muab tso rau hauv lub tshuab nqus tsev. lub scanning electron microscope (SEM) muaj qhov tob ntawm qhov loj thiaj ua tau siv los tshuaj xyuas qhov chaw qauv ntawm cov qauv.
Kuj Paub, tuaj yeem pom tsuas yog nrog lub tshuab ntsuas hluav taws xob? Organelles uas tuaj yeem saib hauv qab electron microscope yog ribosomes, vacuoles, Golgi lub cev, ntxhib endoplasmic reticulum, du endoplasmic reticulum, mitochondria, nuclear membrane, nuclear pores, nucleolus.
Tom qab ntawd, dab tsi organelle tuaj yeem pom nrog lub teeb pom kev zoo?
Organelles uas tuaj yeem pom hauv lub teeb pom kev zoo yog nucleus cytoplasm, cell membrane , chloroplasts thiab phab ntsa ntawm tes. Mitochondria kuj pom nyob rau hauv lub teeb tsom iav tab sis tsis muaj kev tshawb fawb ntxaws.
Dab tsi tuaj yeem pom nrog lub tshuab ntsuas hluav taws xob?
Qhov kis tau tus mob electron microscope yog siv los saib cov qauv nyias (cov ntaub so ntswg, molecules, thiab lwm yam) los ntawm qhov ntawd electrons tau pass tsim ib daim duab projection. Vim nws qhov tob ntawm kev tsom xam, scanning electron microscope yog EM analog ntawm lub suab tso suab microscope.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
Lub ntsuas hluav taws xob ntsuas hluav taws xob ua haujlwm li cas?
Lub taub ntawm lub tester yog kov rau cov neeg xyuas pib (piv txwv li, nws tuaj yeem siv rau ntawm ib lub xov hlau hauv qhov hloov, lossis muab tso rau hauv lub qhov hluav taws xob qhov hluav taws xob). Lub teeb neon siv sij hawm me ntsis tam sim no rau lub teeb, thiab yog li siv tau tus neeg siv lub cev muaj peev xwm mus rau hauv av kom ua tiav lub voj voog
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Cov ntsiab lus twg feem ntau yuav tau txais cov hluav taws xob hauv cov tshuaj lom neeg?
Cov hlau tsis yog hlau yuav tau txais cov khoom siv hluav taws xob kom tau txais Noble Gas teeb tsa. Cov muaj kuj muaj Electron affinities thiab siab Ionization energies. Cov hlau zoo li plam electrons thiab cov hlau tsis yog hlau yuav tau txais electrons, yog li hauv kev cuam tshuam nrog ob pawg no, muaj kev hloov hluav taws xob los ntawm cov hlau mus rau cov hlau tsis yog hlau
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
