Yuav ua li cas lub magnification ntawm lub microscope txiav txim?
Ntau lub chaw soj nstuam tau siv lub tshuab tsom iav, tab sis lawv tsis paub txog cov kev paub txog kev siv tshuab microscopes. Lawv tsuas paub yuav ua li cas khiav lawv, tab sis lawv yuav tsis meej meej txog qee qhov kev nkag siab yooj yim. Yog li niaj hnub no peb yuav tham txog kev nthuav dav ntawm microscopes. xam?
Qee tus neeg yuav hais tias qhov no tsis yog qhov teeb meem yooj yim heev, tab sis nws yog qhov nyuaj me ntsis.
Ua ntej ntawm tag nrho cov, cia peb muab piv txwv: thaum lub magnification ntawm lub stereo microscope eyepiece yog 10 zaug, lub zoom ntau yam ntawm lub zoom lub cev yog: 0.7X-4.5X, thiab lub hom phiaj ntxiv yog: 2X. Tom qab ntawd nws qhov kev nthuav dav yog: 10 npaug 0.7 npaug 2 kom tau txais qhov kev nthuav dav yam tsawg kawg nkaus ntawm lub tshuab tsom iav no: 14 npaug, tom qab ntawd qhov siab tshaj plaws yog: 10 npaug 4.5 npaug 2 sib npaug 90 npaug, tom qab ntawd qhov muag tag nrho ntawm lub tso suab microscope Qhov magnification yog 14. ua 90x. Ntawm chav kawm, qhov no tsuas yog qhov tseeb magnification ntawm lub microscope party. Tom ntej no yog lub microscope digital magnification.
Piv txwv li, yog tias qhov loj ntawm cov zaub yog 17 ntiv tes thiab 1/3 lub koob yees duab microscope siv, ces qhov kev nthuav dav digital ntawm lub koob yees duab microscope piv rau cov lus hauv qab no yog: 72 zaug. Cov mis laij lej ntawm qhov kev nthuav dav digital ntawm lub tshuab tsom iav yog: raws li kev teeb tsa ntawm lub tso suab tso suab tso suab saum toj no, lub cev zoom yog 0.7X-4.5X, thiab lub hom phiaj ntxiv yog 2X. Lub koob yees duab eyepiece yog 1 (yog tias lub koob yees duab eyepiece tsis muaj ntau yam, nws tsis tas yuav ntxiv rau kev suav). Raws li cov qauv: lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification, qhov tsawg kawg nkaus magnification ntawm digital magnification yog: 0.7 zaug 2 zaug 1 zaug 72 yog sib npaug rau: 100.8 npaug, qhov siab tshaj plaws magnification ntawm digital magnification yog : 4.5 x 2 x 1 x 72=648 times. Qhov kev nthuav dav digital yog 100.8 npaug rau 648 zaug.
Hauv qhov no, ob lub qauv yuav tshwm sim:
1. Tag nrho cov optical magnification=magnification ntawm eyepiece X lub magnification ntawm lub hom phiaj lens
2. Digital tag nrho magnification=lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification
Cov mis no haum rau txhua lub tshuab ntsuas, txawm tias nws yog lub tshuab ntsuas metallographic, lub tshuab kuaj kab mob lom neeg, thiab lwm yam.
