Dab tsi yuam kev yuav tsum tau zam nyob rau hauv kev siv lub tshuab microscope
Thaum siv lub tshuab ntsuas ntsuas, yuav tsum tau saib xyuas kom tsis txhob muaj kev ua yuam kev loj ntawm tib neeg hauv kev nyeem ntawv, uas tuaj yeem ua rau pom qhov tsis zoo.
1. Parallax: Lub parallax ntawm qhov ntsuas qhov muag yog vim qhov tseeb tias cov duab ntawm cov khoom ntsuas tsis nyob hauv tib lub dav hlau raws li tus kav rau kev ntsuas, yog li thaum tus neeg soj ntsuam lub qhov muag txav mus, yuav muaj qhov sib txawv txav ntawm cov duab thiab tus kav.
Lub microscope nyeem ntawv muaj ib lub qhov muag thiab lub hom phiaj lens. Cov kab kos yog nyob nruab nrab ntawm lub qhov muag thiab lub hom phiaj lens. Txhawm rau tshem tawm cov parallax, lub eyepiece yuav tsum tau kho ua ntej kom pom cov duab ntawm crosshair kom pom tseeb, thiab tom qab ntawd lub pob qhov rooj nqa yuav tsum tau kho kom pom cov duab ntawm cov khoom kom pom tseeb. Tsiv koj ob lub qhov muag , yog tias tsis muaj qhov sib txawv txav ntawm cov duab ntawm cov khoom ntsuas thiab cov duab crosshair, nws txhais tau tias lawv nyob hauv tib lub dav hlau duab.
2. Pitch yuam kev: Vim tias yuav tsum muaj qhov sib txawv ntawm cov xov sab hauv thiab cov xov sab nraud ntawm cov khoom siv ntsuas helical, cov kev nyeem ntawv sib txawv ntawm cov lus qhia kev sib hloov yuav tsum sib txawv. Qhov txawv no hu ua pitch yuam kev. Yog li ntawd, thaum siv lub tshuab ntsuas ntsuas ntsuas qhov ntev, cov hlaws yuav tsum tau ua kom zoo nyob rau hauv tib qho kev taw qhia, ua raws li ob qho kawg ntawm cov khoom yuav tsum ntsuas, thiab tsis txhob rov qab mus rau hauv nruab nrab, txhawm rau tshem tawm qhov yuam kev.
