Yuav ua li cas kho tus polarizer ntawm polarized microscope
Hauv kev ua haujlwm zoo, kev co cov kev taw qhia ntawm sab saud thiab sab hnub tuaj lossis sab hnub tuaj sab hnub tuaj, thiab txhua qhov kev qhia sab hnub tuaj ntawm cov kab rov tav thiab cov kab rov tav. Qee lub sij hawm tsuas yog ib qho qis dua polarizer yog siv rau kev soj ntsuam, thiab kev co cov kev co ntawm cov qis dua polarizer yuav tsum muaj kev txiav txim siab, yog li cov polarizer yuav tsum ntsuas lub sijhawm ua haujlwm.
1. Nrhiav kom pom ntawm Crosshair hauv Eyepiece
Kuaj seb cov Crosshahahahahahahahahahad yog orthogonal thiab seb nws puas sib xws nrog cov kev co ntawm cov iav sab saud thiab sab hauv qab zib. Ib txhij xaiv ib daim biotite nrog cov kab kev ua tiav, kaw cov nplai ntawm cov theem ntawm cov theem, thiab tom qab ntawd kaw cov nplai mus rau lwm tus lej ntawm theem. Qhov sib txawv ntawm ob teev degrees yog 90 degree, qhia tias tus ntoo khaub lig yog orthogonal.
2. Kev txiav txim siab thiab kho kho ntawm qhov kev co ntawm daim iav polarizing
Qhov laj thawj rau kev siv biotite los xyuas cov kev co ntawm tus polarizer yog tias biotite yog qhov dav dav pob tshab uas yog cov xeeb ceem heev nyob hauv ib cheeb tsam polarization heev. Firstly, nrhiav tau qhov tseeb thiab tuav nws lub ntsej muag, thawb tawm ntawm lub ntsej muag ntawm tus kab mob sab saud, tig mus rau theem sab saud, thiab saib cov xim hloov pauv ntawm biotite. Vim tias biotite nqus cov teeb nyob rau hauv cov kev taw qhia centavage * muaj zog, thaum cov kev coj ntawm cleavage seam tau yog qhov kev co ntawm qis polarizer.
3. Kho kev txhim kho ntawm Orthoogonal Polarization ntawm Sab Sauv thiab Qaum Qaum Ntuj
Tom qab sib txawv ntawm cov kev taw qhia ntawm tus lej qis dua, tshem tawm cov yeeb yaj kiab nyias nyias thiab thawb nws rau ntawm daim duab sab saud, uas yog, txawm nws yog lub xeev ploj. Yog tias nws yog xim dub, nws qhia tau tias cov kev co ntawm cov kev taw qhia ntawm cov polarizations sab saud thiab qis dua yog orthogonal rau ib leeg. Txwv tsis pub, tus polarizer sab saud yuav tsum muaj qhov ntsuas los ntawm kev sib hloov nws kom txog thaum lub teb ntawm kev pom yuav * tsaus. Thaum tig, cov ntsia hlau ntawm cov polarizer sab saud yuav tsum tau xoob ua ntej, ntsuas kom raug, thiab tom qab ntawd nruj.
