Taw qhia rau cov ntsiab lus tseem ceeb thiab cov yam ntxwv ntawm Polarizing Tsom Xyooj
1, Cov yam ntxwv ntawm Pauv Lub Vev Xaib Yees Duab: Polarization Lub tsom iav Polarization yog ib hom tsom iav tau siv los txheeb xyuas qhov kho tshiab ntawm cov qauv zoo. Ib yam dej twg nrog birefringence tuaj yeem qhia meej meej nyob rau hauv ib tug polarizing tsom. Ntawm chav kawm, cov tshuaj no tseem tuaj yeem siv cov txheej txheem staining, tab sis qee qhov tsis yooj yim sua thiab yuav tsum tau siv lub micrigizing microscope. Cov yam ntxwv ntawm kev sib tw microscope yog tus txheej txheem ntawm kev hloov lub teeb zoo tib yam rau kev tshuaj xyuas cov iav tshuaj xyuas, txhawm rau txhawm rau ua kom pom cov tshuaj ntsuab (isotropic) lossis biriotropic). Birefringence yog tus yam ntxwv tseem ceeb ntawm muaju. Yog li ntawd, polarizing microscopes tau siv dav hauv cov liaj teb xws li cov zaub mov thiab chemistry. Hauv biology, ntau cov qauv kuj muaj cov birarringence, uas yuav tsum siv polarizing microscopes kom paub qhov txawv lawv. Hauv botany, xws li paub txog cov fibers, chromosomes, ntxaij, cov plaub hau hmoov txhuv nplej siab, thiab muaj cov muaju hauv cytoplasm thiab cov ntaub so ntswg. Hauv cov nroj tsuag pathology, kev ntxeem tau ntawm cov kab pathogens feem ntau ua rau hloov pauv cov tshuaj ntawm cov ntaub so ntswg, uas tuaj yeem txheeb tau los ntawm polarized lub teeb ci ntsa iab. Kev tshawb fawb polarized yog siv feem ntau hauv tib neeg thiab tsiaj txoj kev qhia kom paub cov pob txha, cov hniav, cov roj ntsha, cov leeg qog, thiab cov plaub hau.
2, Lub hauv paus ntsiab lus tseem ceeb ntawm Kev Ua Yeeb Yam Lub Vev Xaib:
(1) monorefraction thiab birgefringence: thaum lub teeb kis los ntawm cov khoom siv ntawm ipics, xws li cov roj ntsha tsis tau, xws li cov roj ntsha li qub, kua dej, thiab cov khib nyiab amorphous; Yog tias lub teeb hla dhau lwm cov khoom, nws cov lus tshaj tawm, kev nqus khoom ntawm cov tawv nqaij tawv, thiab cov muaju, cov fibers, thiab lwm yam.
(2) Polarization tshwm sim ntawm lub teeb: raws li cov yam ntxwv ntawm kev co, lub teeb vuag tuaj yeem faib ua ntuj ci thiab polarization. Qhov kev co ntawm lub teeb ntuj yog tias nws muaj ntau qhov kev sib tw ntawm lub teeb yoj kev tshaj tawm, thiab cov kev co ntawm txhua lub dav hlau yog tib yam; Lub teeb ntuj ci tuaj yeem dhau los ua lub teeb pom kev uas tshee hnyo uas tsuas yog nyob rau hauv ib qho kev xav, thiab kev nqus lub teeb pom kev zoo "polarized lub teeb" lossis "polarized lub teeb". Cias muab, nws yog linearly polarized lub teeb uas vibrates tsuas yog nyob rau hauv ib txoj kab ncaj nraim. Thaum lub teeb nkag mus rau hauv lub cev birefringent, nws tau muab faib ua ob hom ntawm linarly polarized lub teeb, a thiab b, raws li qhia hauv daim duab. Qhov kev co ntawm ob leeg yog sib tshuam rau txhua lwm yam, tab sis qhov nrawm, ua kom muaj siab dav dav.
