Muaj ntau yam teeb meem uas tau txais lub tshuab tsom
Nqe Lus Nug 1. Tus nqi ntawm lub tshuab tsom iav li cas?
Ntau tus neeg yuav khoom siv lub tshuab ntsuas hluav taws xob tau nug peb cov lus nug xws li, uas yog, "Lub tshuab ntsuas hluav taws xob ntau npaum li cas?" Kuv tsuas yog xav kom tau txais lub tswv yim dav dav ntawm cov lus hais ntawm lub tshuab tsom iav, thiab peb kwv yees tias peb tsuas yog muab tus nqi tsis meej nrog tus nqi sib txawv loj heev. Lub ntsiab yog vim li cas rau qhov tshwm sim yog nyob rau hauv lub configuration ntawm lub microscope. Qhov tseeb, kev yuav lub tshuab tsom iav zoo ib yam li kev yuav lub computer - txhua yam yuav tsum tau teeb tsa raws li koj xav tau. Piv txwv li, koj xav tau ntau hom kev soj ntsuam ( cuam tshuam rau tus naj npawb ntawm lub hom phiaj lo ntsiab muag), txawm tias koj xav tau software, txawm tias koj xav tau CCD, thiab lwm yam. Cov kev cai no cuam tshuam rau cov lus hais ntawm lub tshuab tsom. Koj yuav tsum paub tias qhov tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws ntawm tag nrho lub tshuab tsom iav yog lub hom phiaj lens. , nws tus lej yuav cuam tshuam rau tus nqi ntawm lub tshuab tsom iav.
Nqe Lus Nug 2: Koj puas paub tias lub tshuab tsom iav zoo li cas rau cov qauv koj xav sim ua ntej yuav khoom?
Microscopes tuaj yeem muab faib ua cov haujlwm sib txawv raws li cov qauv kev soj ntsuam: feem ntau muaj metallographic microscopes, polarizing microscopes, stereo microscopes, biological microscopes, fluorescence microscopes, thiab lwm yam. Cov khoom siv microscopes sib txawv siv ntau txoj hauv kev. Polarizing microscopes feem ntau yog siv rau hauv kev tshawb pom ntawm anisotropic non-metallic cov ntaub ntawv xws li geological ores. Metallographic microscopes feem ntau yog siv rau hauv kev soj ntsuam, txheeb xyuas thiab txheeb xyuas cov qauv sab hauv ntawm ntau yam khoom siv tsis zoo xws li hlau. Nws yog tsim rau factories, mines, enterprises, cov tsev kawm ntawv qib siab thiab scientific research departments. Nruab nrog lub koob yees duab ntaus ntawv, lub cuab yeej tuaj yeem ntes metallographic atlases, ntsuas thiab txheeb xyuas cov atlases, thiab kho, tso zis, khaws cia, thiab tswj cov duab. Stereo microscopes yog tsim rau micron-theem tiag tiag kev tsom xam, kev tshawb nrhiav pob txha, tshuaj xyuas cov khoom siv hluav taws xob hauv kev lag luam, kev txheeb xyuas cov ntawv luam tawm hauv Circuit Court, kev txheeb xyuas qhov tsis xws luag (luam ntawv misalignment, ntug vau, thiab lwm yam) hauv kev luam tawm Circuit Court sib dhos, kev txheeb xyuas ntawm ib leeg. -board PCs, Thiab txhua qhov chaw uas muaj kev ceev faj soj ntsuam ntawm tus qauv saum npoo, nruab nrog kev ntsuas software los ntsuas ntau cov ntaub ntawv. Biological microscopes yog tsim nyog rau kev kuaj mob, kuaj, qhia, thiab tshawb fawb hauv kev kho mob thiab kev noj qab haus huv, tsev kawm ntawv, thiab cov chaw tshawb fawb tshawb fawb. Yog li ntawd, ua ntej kev yuav khoom, koj yuav tsum paub seb tus qauv koj xav soj ntsuam yog dab tsi, yog li ntawd tus tub lag luam tuaj yeem pom zoo rau koj lub tshuab ntsuas qhov tsim nyog.
Nqe Lus Nug 3: Kuv puas yuav tau txais lub tshuab tsom iav ncaj qha lossis lub tshuab tsom iav inverted?
Ua ntej teb cov lus nug no, nws yuav tsum paub meej tias qhov sib txawv ntawm lub tshuab tsom iav ncaj qha thiab lub tshuab ntsuas inverted:
Metallographic microscope, tseem hu ua cov khoom siv microscope, feem ntau yog siv los soj ntsuam cov qauv ntawm cov ntaub so ntswg hlau, uas tuaj yeem muab faib ua upright metallographic microscope thiab inverted metallographic microscope.
Lub upright metallographic microscope tsim cov duab zoo thaum lub sijhawm soj ntsuam, uas coj tau yooj yim rau tus neeg siv kev soj ntsuam thiab kev txheeb xyuas. Ntxiv nrog rau kev tshuaj xyuas thiab kev txheeb xyuas cov qauv hlau nrog qhov siab ntawm 20-30mm, nws yog raws li tib neeg lub neej txhua hnub. , yog li nws yog dav siv nyob rau hauv pob tshab, translucent los yog opaque tshuaj. Kev soj ntsuam cov khoom loj dua 3 microns thiab tsawg dua 20 microns, xws li cermets, electronic chips, printed circuits, LCD substrates, films, fibers, granular objects, coatings and other material surfaces and tracts, can have good imaging effects. Tsis tas li ntawd, lub koob yees duab sab nraud tuaj yeem txuas tau yooj yim rau lub vijtsam video thiab lub khoos phis tawj rau lub sijhawm tiag tiag thiab zoo li qub thiab dynamic duab saib, khaws cia, kho, luam ntawv, ua ke nrog ntau yam software kom tau raws li cov kev xav tau ntawm kev tshaj lij metallography, kev ntsuas, thiab kev sib tham sib qhia. Inverted metallographic microscope siv cov txheej txheem ntawm lub dav hlau kho qhov muag los txheeb xyuas thiab txheeb xyuas cov qauv ntawm ntau yam hlau thiab alloys. Nws yog ib qho tseem ceeb rau kev tshawb fawb metallographic hauv metallography. Nws tuaj yeem siv dav hauv cov chaw tsim khoom lossis chaw soj nstuam rau kev tshuaj xyuas zoo thiab cov khoom siv raw. , los yog kev tshawb fawb thiab kev soj ntsuam ntawm metallographic qauv ntawm cov ntaub ntawv tom qab cov txheej txheem kev kho mob, thiaj li yuav muab intuitive tsom xam, nws yog cov cuab yeej tseem ceeb rau kev txheeb xyuas zoo thiab tsom xam ntawm casting, smelting, thiab tshav kub kho nyob rau hauv mining, metallurgy, manufacturing, thiab mechanical kev lag luam. Nyob rau hauv xyoo tas los no, kev lag luam microelectronics xav tau high-magnification planar microscopy los txhawb cov chips. Yog li ntawd, metallographic microscopes tau nkag mus rau hauv daim teb no rau kev txhawb nqa thiab siv, thiab tau raug txhim kho tsis tu ncua kom tau raws li qhov tshwj xeeb xav tau ntawm kev lag luam. Inverted metallurgical microscope, vim hais tias qhov kev soj ntsuam nto ntawm tus qauv coincides nrog rau saum npoo ntawm workbench downwards, thiab lub hom phiaj soj ntsuam nyob rau hauv lub workbench saib upwards. Daim ntawv soj ntsuam no tsis txwv los ntawm qhov siab ntawm tus qauv. Zoo nkauj thiab dav, lub hauv paus ntawm lub inverted metallographic microscope muaj thaj chaw txhawb nqa loj, qhov nruab nrab ntawm lub ntiajteb txawj nqus yog qis, muaj kev nyab xeeb, ruaj khov thiab txhim khu kev qha, lub qhov muag thiab qhov chaw txhawb nqa yog inclined ntawm 45 degree, ua rau kev soj ntsuam zoo.
