Qhia koj lub hauv paus ntsiab lus ntawm polarizing microscope
Polarizing microscope yog ib qho khoom siv kho qhov muag siv los paub qhov txawv ntawm qhov tseeb thiab nyob deb ntawm cov qauv me me ntawm cov tshuaj lom neeg. Txhua yam tshuaj uas muaj birefringence muaj peev xwm ua kom pom tseeb nyob rau hauv polarizing microscope. Yog li ntawd, nws yog dav siv nyob rau hauv engineering kev qhuab qhia xws li hydrology.
Lub hauv paus ntsiab lus ntawm polarizing microscope:
1. Ib qho refraction thiab ob chav refraction
Thaum lub teeb ci ci rau ntawm qee yam khoom, qhov ntsuas qhov ntsuas pom thiab qhov loj ntawm lub teeb sib txawv vim qhov sib txawv ntawm thaj tsam ntawm lub teeb. Cov khoom no muaj birefringence, thiab dav siv lead ua, minerals, thiab lwm yam yog nyob rau hauv birefringence. Yog hais tias cov khoom yog irradiated, lub zog ntawm lub teeb yuav tsis raug hloov vim yog cov kev taw qhia ntawm irradiance, ces nws muaj ib tug refraction, xws li cov pa roj, kua thiab lwm yam.
2. Qhov ua rau thiab cov nyhuv ntawm lub teeb polarized
Qhov sib txawv ntawm polarizing microscope thiab lwm yam optical microscopes yog tias nws muaj ob lub polarizing li: polarizer thiab analyzer. Thaum lub teeb ci nkag mus rau tib lub sijhawm, cov polarizer thiab cov ntsuas ntsuas nyob rau hauv ib qho kev sib piv, tom qab ntawd cov kab pom kev pom yog ci dua, yog tias nws nyob rau hauv txoj kab ntsug, ces kab ntawm qhov pom yog tsaus, thiab nyob rau hauv ib tug skewed. lub xeev, txoj kab ntawm qhov pom yog ci dua theem nrab.
3. Lub polarization ntawm lub teeb
Raws li kev vibration yam ntxwv ntawm microwaves, nws tuaj yeem muab faib ua hnub ci thiab polarized teeb. Tom qab lub hnub ci tau pom thiab pom, nws dhau los ua microwaves uas tsuas yog vibrate hauv ib qho kev taw qhia, thiab dhau los ua lub teeb polarized.
4. Kev cuam tshuam xim
Thaum soj ntsuam ib qho khoom siv birefringent, nrog rau kev sib hloov ntawm theem, qee cov xim yuav tshwm sim hauv kab pom. Yog vim li cas rau qhov tshwm sim no yog cov xim cuam tshuam, thiab nws cov yam ntxwv kev faib tawm yog nyob rau hauv cov khoom birefringent Thickness thiab hom.
Polarizing microscopes tau ua rau muaj txiaj ntsig zoo rau kev tshawb fawb thiab kev tshawb pom ntawm geological thiab mineral tsom xam, microbiology, tshuaj tshuaj xyuas thiab lwm yam. Yog li ntawd, thaum siv tag nrho cov txheej txheem, nws yog ib qho tsim nyog yuav tsum tau ua haujlwm raws li tus qauv, thiab ua si qhov txiaj ntsig zoo tshaj plaws raws li nws cov qauv.
