Qhov zoo tshaj plaws microscope xaiv txoj kev
Microscopes yog cov cuab yeej kho qhov muag, thiab lawv cov thev naus laus zis tseem ceeb yog kev siv tshuab kho qhov muag. Qhov zoo ntawm cov khoom yog nyob ntawm qhov kho qhov muag system (xws li lub teeb pom kev zoo, lub hom phiaj lo ntsiab muag, thiab lwm yam), uas kuj yog lub hauv paus ntsiab lus ntawm kev yuav khoom siv lub tshuab tsom. Hauv cov chaw tsim khoom siv microscope txawv teb chaws (Zeiss, Leica, Nikon, thiab Olympus), qhov zoo sib txawv. Cov neeg siv yuav tsum txheeb xyuas qhov tseeb hauv cov txheej txheem xaiv thiab tsis txhob mus yuam kev, thaum kawg ua rau kev poob nyiaj txiag tsis zoo.
1, Imaging zoo
Peb tsuas yog siv cov qauv duab kho qhov muag kom tau txais cov duab microstructure siv lub tshuab tsom iav, thiab tom qab ntawd ua qhov kev soj ntsuam zoo thiab muaj nuj nqis ntawm cov duab, yog li qhov zoo ntawm cov duab yog qhov tseem ceeb tshaj plaws. Cov duab ntshiab raug xa mus rau cov duab ntse hauv thaj tsam ntawm metallography. Txhawm rau kom tau txais cov duab ntse, plaub yam xwm txheej yuav tsum tau ua raws li: qhov sib txawv siab, siab ci ci, tsim cov xim zoo, thiab kev daws teeb meem siab. Kev sib piv, ci ntsa iab, thiab xim kho dua tshiab yog qhov tseeb ntawm qhov chaw uas cov neeg siv yuav saib tsis pom thaum xaiv, qhov muag tsis pom kev daws teeb meem thiab ua rau kev xaiv tsis ua haujlwm. Piv txwv li, cov duab zoo ntawm Japanese hom microscope yuav los ntawm lub tuam txhab loj hauv tsev steel hauv xyoo 2000 yog qhov qis dua ntawm German Zeiss microscope yuav xyoo 1985, tab sis tus lej aperture ntawm lub hom phiaj lens yog siab dua li ntawm Zeiss. Qhov laj thawj yog qhov yooj yim heev. Thaum tsim cov tshuab tsom iav, cov tuam txhab lag luam no tsuas yog xav txog ib qho tseem ceeb uas cuam tshuam rau kev pom zoo - kev daws teeb meem, thaum tsis quav ntsej lwm yam tseem ceeb xws li qhov sib txawv, ci ntsa iab, thiab xim kho dua tshiab. Hauv qhov no, Zeiss los ntawm lub teb chaws Yelemees tau ua haujlwm zoo los ntawm kev siv ICCS optical system thiab anti glare technology los txhim kho qhov sib piv, ci ntsa iab, thiab xim luam tawm ntawm cov duab, uas ua rau muaj kev ntxhib los mos thiab cov xim zoo nkauj. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tiav cov duab tsom xam.
2, Mechanical stability
Muaj cov duab zoo tsis txaus, tab sis nws yuav tsum tau ua kom muaj lub xeev zoo nyob rau lub sijhawm. Peb hu qhov no 'txoj kev ruaj ntseg' vim tias lub tshuab ntsuas hluav taws xob tsis yog cov khoom siv qis thiab lawv lub neej ua haujlwm ib txwm yuav tsum muaj tshaj 30 xyoo. Hauv qhov no, nws raug nquahu kom cov neeg siv tsom mus rau cov ntsiab lus hauv qab no: 1. Cov khoom siv raw 2. Kev tsim khoom raug 3. Kev tsim kho tshuab 4. Keeb kwm (tam sim no, ntau lub tshuab tsom iav tuaj txawv teb chaws muaj kev koom tes hauv Suav teb).
