Lub teeb pom kev zoo yog qhov muaj txiaj ntsig zoo rau kev kuaj uas muaj xim zoo ib yam, piv txwv li chloroplasts hauv cov cell cog
- Sib piv cov txheej txheem transillumination siv rau tsim qhov sib piv hauv cov qauv ntawm cov ntaub so ntswg (1.559 μm/pixel)
- Ci - teb teeb pom kev zoo, piv txwv sib piv los ntawm kev nqus lub teeb hauv qhov piv txwv.
Hais txog qhov no, thaum twg koj yuav siv lub tsom iav ci ntsa iab?
1 Brightfield Microscopy . Brightfield microscopy yog feem ntau siv hauv kev tshawb fawb microcirculatory raws li nws muab txoj hauv kev yooj yim thiab tus nqi pheej yig ntawm kev tau txais cov ntaub ntawv ntawm lub nkoj qhov ntev, kev txav ntawm cov khoom tsim thiab, nrog rau ntxiv ntawm cov cuab yeej tshwj xeeb, spectrophotometric hloov pauv.
Qhov thib ob, dab tsi yog qhov zoo ntawm kev siv theem sib piv microscopy tshaj qhov kaj? Zoo ntawm theem sib piv tsom iav : Nws muaj peev xwm pom tau qee cov qauv uas tsis pom pom. Qhov no suav nrog qee cov cell organelles uas tsis tuaj yeem pom zoo hauv thaj teb kaj . Qee zaum cov theem sib piv duab subjectively zoo dua li a thaj teb kaj duab vim yog cov ntsiab lus pom.
Ib sab saum toj no, dab tsi tuaj yeem kuaj mob siv lub tshuab tsom iav zoo nkauj?
Siv thiab Kev nce qib mus rau qee qhov, brightfield microscopy yog siv hauv feem ntau cov kev qhuab qhia xav tau microscopic kev tshawb nrhiav. Lub neej kev tshawb fawb, tshwj xeeb yog microbiology thiab bacteriology, ib txwm tso siab rau brightfield txheej txheem. Cov txheej txheem no tau raug siv los saib cov hnoos qeev lossis cov cell nyob.
Dab tsi yog qhov kev daws teeb meem siab tshaj plaws hauv lub tshuab tsom pom ci ci?
Txawm hais tias 200 nanometers suav tias yog qhov pom tau zoo daws teeb meem rau kho qhov muag tsom iav , kev daws teeb meem siab dua tuaj yeem tau txais kev siv fluorescence microscopy.

Thaum twg koj yuav siv lub raj fenestrated?
![Thaum twg koj yuav siv lub raj fenestrated? Thaum twg koj yuav siv lub raj fenestrated?](https://i.answers-medical.com/preview/medical-health/13866178-when-would-you-use-a-fenestrated-trach-tube-j.webp)
Cuffed fenestrated tubes tshwj xeeb yog siv rau hauv cov neeg mob uas tau txiav tawm ntawm lawv cov tracheostomy thaum lub sijhawm cuff nce thiab deflation xav tau. Cov raj uas tsis tau muab fenestrated tau siv rau cov neeg mob uas tsis vam khom lub raj raj
Kev siv lub tshuab tsom me me yog dab tsi?
![Kev siv lub tshuab tsom me me yog dab tsi? Kev siv lub tshuab tsom me me yog dab tsi?](https://i.answers-medical.com/preview/medical-health/13950218-what-are-the-uses-of-compound-microscope-j.webp)
Compound microscopes yog siv los saib cov qauv me me uas tsis tuaj yeem txheeb xyuas qhov muag liab qab. Cov qauv no feem ntau muab tso rau ntawm ib lub swb nyob rau hauv lub tshuab tsom. Thaum siv lub tsom iav tso suab, muaj chav ntau nyob hauv qab lub tsom iav rau qhov piv txwv loj xws li pob zeb lossis paj thiab swb tsis xav tau
Vim li cas lub tshuab tsom iav hu ua lub tshuab tsom me me?
![Vim li cas lub tshuab tsom iav hu ua lub tshuab tsom me me? Vim li cas lub tshuab tsom iav hu ua lub tshuab tsom me me?](https://i.answers-medical.com/preview/medical-health/13965807-why-a-microscope-is-called-a-compound-microscope-j.webp)
COMPOUND MICROSCOPES thiaj li raug hu vim tias lawv tau tsim nrog cov kab ke sib xyaw ua ke. Lub hom phiaj lo ntsiab muag muab thawj qhov kev nthuav dav uas yog compounded (multiplied) los ntawm ocular lens (qhov muag)
Koj yuav tsum sim kawm dab tsi thaum koj siv lub tshuab tsom?
![Koj yuav tsum sim kawm dab tsi thaum koj siv lub tshuab tsom? Koj yuav tsum sim kawm dab tsi thaum koj siv lub tshuab tsom?](https://i.answers-medical.com/preview/medical-health/13985407-what-should-you-try-to-learn-as-you-use-the-microscope-j.webp)
Hauv koj lub qhov muag, koj yuav tsum sim kawm dab tsi thaum koj siv lub tsom iav? Nco ntsoov ua kom koj ob lub qhov muag qhib (nws yuav siv qee qhov kev xyaum) tab sis rau cov neeg uas hnav tsom iav tsis txhob cia koj lub tsom iav tsoo lub qhov muag thiab tsis txhob saib cov swb yam tsis muaj daim npog
Vim li cas koj thiaj li yuav tsum tau kho lub diaphragm ntawm lub tshuab tsom?
![Vim li cas koj thiaj li yuav tsum tau kho lub diaphragm ntawm lub tshuab tsom? Vim li cas koj thiaj li yuav tsum tau kho lub diaphragm ntawm lub tshuab tsom?](https://i.answers-medical.com/preview/medical-health/14029003-why-do-you-need-to-adjust-the-diaphragm-on-a-microscope-j.webp)
Diaphragm los yog Iris: Muaj ntau lub tshuab tsom iav muaj lub voj voog nyob hauv qab theem. Cov diaphragm no muaj qhov sib txawv qhov sib txawv thiab siv los sib txawv qhov sib txawv thiab qhov loj ntawm lub khob hliav qab ntawm lub teeb uas tau npaj siab nce mus rau hauv swb. Tsis muaj txoj cai teeb tsa hais txog kev teeb tsa twg los siv rau lub zog tshwj xeeb
