Cov cell phab ntsa, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, thiab ribosomes yooj yim pom nyob rau hauv no kis tau tus mob. electron micrograph . (Courtesy ntawm Brian Gunning.)
Ua raws li qhov kev pom no, dab tsi tuaj yeem pom nrog lub tshuab ntsuas hluav taws xob?
Electron microscopes yog siv los soj ntsuam ultrastructure ntawm ib tug ntau yam ntawm lom thiab inorganic specimens nrog rau cov kab mob, cell, loj molecules, biopsy kuaj, hlau, thiab crystals. Kev lag luam, electron microscopes feem ntau yog siv rau kev tswj kom zoo thiab tsis ua hauj lwm tsom xam.
Ib sab saum toj no, hom microscope tuaj yeem pom cov hlwb? Compound microscopes yog teeb illuminated. Daim duab pom nrog lub tshuab ntsuas no yog ob sab. Qhov no microscope yog feem ntau siv. Koj tuaj yeem saib cov hlwb ntawm tus kheej, txawm tias muaj sia nyob.
Ib yam li ntawd ib tug yuav nug, cov qauv ntawm tes tuaj yeem pom tsuas yog nrog lub tshuab ntsuas hluav taws xob?
Ribosomes
Electron microscopes puas tuaj yeem pom cov cell nyob?
Electron microscopes yog cov cuab yeej muaj zog heev rau kev pom cov qauv lom neeg. Lawv pab cov kws tshawb fawb saib cov hlwb , cov ntaub so ntswg thiab cov kab mob me me hauv kev nthuav dav heev. Txawm li cas los xij, cov qauv tshuaj lom neeg no ua tau 'tsis raug saib rau electron microscopes thaum tseem ciaj sia.

Lub teeb ntsuas hluav taws xob siv los kuaj xyuas hluav taws xob li cas?
Lub teeb ntsuas hluav taws xob siv lub teeb tuav hauv ib qho kev sojntsuam txuas nrog tus pas nrig taw tes nrog cov hlau txuas txuas. Qhov kev tsim no yog qhov zoo tshaj plaws rau kev tho cov hlau, kuaj lub fuse lossis kuaj xyuas qhov nqi ntawm lub roj teeb. Yog tias muaj hluav taws xob tam sim no, lub teeb yuav teeb pom tseeb tias lub voj voog muaj zog thiab ua haujlwm zoo
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
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
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
