Tam sim no muaj ntau txoj hauv kev los saib xyuas cov yeeb yaj kiab nyias hauv lub tshuab nqus tsev, feem ntau suav nrog: kev saib xyuas qhov muag, kev saib xyuas tus nqi ruaj khov (hloov siab), siv lead ua oscillation xyuas, thiab kev saib xyuas lub sijhawm. Kab lus no yuav qhia peb txoj hauv kev: kev saib xyuas qhov muag, kev saib xyuas tus nqi ruaj khov (hloov siab heev), thiab kev saib xyuas siv lead ua oscillation. Kev saib xyuas qhov muag, tseem hu ua kev saib xyuas ncaj qha, siv lub qhov muag los saib xyuas cov yeeb yaj kiab. Thaum lub sij hawm cov txheej txheem kev loj hlob ntawm zaj duab xis, cuam tshuam phenomena ua rau cov xim hloov, thiab peb tswj cov yeeb yaj duab thickness raws li cov xim hloov. Txoj kev no muaj qee qhov kev ua yuam kev thiab tsis yog qhov tseeb, xav tau kev paub dhau los.
Tsau -tus nqi (hnyav-tus nqi) kev saib xyuas: Qhov no feem ntau yog siv kev saib xyuas qhov muag pom kev pom kev. Heev - tus nqi saib xyuas txoj kev: Raws li cov yeeb yaj kiab thickness nce, nws qhov kev xav tau thiab kev xa tawm hloov raws li. Thaum qhov kev cuam tshuam los yog kev xa mus txog qhov chaw siab heev, qhov kho qhov muag thickness ND ntawm txheej tuaj yeem txiav txim siab ua tus lej ntau ntawm ib qho -quarter ntawm kev soj ntsuam wavelength (λ). Txawm li cas los xij, qhov huab- tus nqi txoj kev muaj qhov yuam kev loj heev vim tias qhov kev cuam tshuam los yog kev hloov pauv qeeb qeeb heev ze ntawm tus nqi huab; uas yog, R / T tsuas yog hloov tom qab qhov tseem ceeb ntawm cov yeeb yaj kiab thickness ND. Txoj hauj lwm rhiab tshaj plaws yog nyob ntawm ib - yim ntawm lub wavelength. Tsau- txoj kev saib xyuas tus nqi: Txoj kev no siv qhov tseeb tias qhov chaw nres tsheb ntawm txheej tsis nyob ntawm ib qho -lub quarter ntawm kev soj ntsuam wavelength. Tom qab ntawd, lub khoos phis tawj suav cov kev cuam tshuam (lossis xa tawm) ntawm tag nrho cov yeeb yaj kiab tuab ntawm wavelength 1, uas yog qhov chaw nres tsheb ntawm txheej. Crystal oscillation xyuas: Lub hauv paus ntsiab lus ua haujlwm ntawm siv lead ua oscillation yog raws li lub hauv paus ntsiab lus uas qhov kev vibration zaus ntawm quartz siv lead ua yog inversely proportional rau nws pawg. Txawm li cas los xij, ib qho teeb meem ntawm kev saib xyuas quartz yog tias thaum cov yeeb yaj kiab thickness nce mus rau ib theem, qhov kev vibration zaus tsis yog linearly cuam tshuam nrog lub thickness vim cov khoom ntawm quartz nws tus kheej. Hauv qhov no, yuav tsum siv lub quartz oscillator tshiab.
Ob peb txoj kev saib xyuas txhua tus muaj qhov zoo thiab qhov tsis zoo, tab sis rau ntau- txheej txheej, kev saib xyuas qhov muag feem ntau yog thawj txoj hauv kev, ntxiv los ntawm quartz siv lead ua oscillation. Tsis tas li ntawd, rau qee cov txheej txheem uas xav tau kev txhaj tshuaj roj thaum lub sijhawm txheej txheej, cov ntsuas ntws los yog ntsuas lub siab yog xav tau, uas yuav tsum muaj cov valves thiab photoelectric sensing systems rau kev tswj. Lub tshuab nqus tsev txheej kuj yuav tsum muaj kev sib hloov tswj qhov system, qhov twg lub kaus lub ntsiab ncej tau muab tso rau hauv cov kabmob, thiab lub cev muaj zog tsav cov kabmob kom tig lub kaus. Tom qab ntawd qhov kev sib hloov ceev yog tswj los ntawm PLC. Lub crucible rotation yog tsav los ntawm lub cev muaj zog thiab siv photoelectric induction suav, thaum lub shielding phaj rotates siv pneumatic hloov. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua tiav, lub tshuab nqus tsev vacuum, lub tshuab nqus tsev vacuum yuav tsum tau ua kom txias, ua kom cov huab cua sab hauv kom txias rau -}130 degrees Celsius thiab khov thiab tshem tawm cov dej vapor. Kev tswj hluav taws xob feem ntau yog siv PLC tsis siv neeg tswj. Qhov kev pab cuam ua ntej-tsim yog thawj lub tswv yim rau hauv PLC, thiab lub hauv paus ntsiab lus ntawm lub processor txuas nrog rau txhua qhov tsis muaj kev thauj khoom ntawm lub vaj huam sib luag ua haujlwm. Thaum lub hloov pauv ntawm lub vaj huam sib luag ua haujlwm raug nias, cov ntaub ntawv raug xa mus rau lub hauv paus processor, thiab tom qab ntawd lub hauv paus tswj kev txheeb xyuas thiab teeb meem cov lus qhia rau ceg circuits kom ua tiav thiab ua tiav qhov kev txiav txim.
Lub tshuab nqus tsev txheej tshuab yog cov cuab yeej ua ke nrog ntau yam kev qhuab qhia. Lawv suav nrog cov thev naus laus zis thev naus laus zis tshaj plaws, kev tswj cov thev naus laus zis, hluav taws xob automation, IT thev naus laus zis, tub yees yees, microcircuit integrated systems, high-voltage control systems, mechanical technologies, processing technologies, optoelectronic, optical control technologies technologies, optoelectronic sensing technologies, kev sib txuas lus technologies, nqus technologies, nyias- zaj duab xis optics thiab txheej technologies, thiab lwm yam. Lub tshuab nqus tsev txheej tshuab tuaj yeem suav tias yog tus neeg sawv cev ntawm kev lag luam tawm tshiab. Niaj hnub no, lub tshuab nqus tsev txheej tshuab tau siv dav, tshwj xeeb tshaj yog hauv kev tsim cov yeeb yaj kiab nyias. Cov yeeb yaj kiab nyias nyias tsim tau siv rau hauv ntau lub tshuab optoelectronic thiab cov cuab yeej kho qhov muag, xws li cov koob yees duab digital, digital camcorders, telescopes, projectors, lub zog tswj, kev sib txuas lus kho qhov muag, tso saib thev naus laus zis, interferometers, khoom siv satellites thiab missiles, semiconductor lasers, microelectromechanical systems, cov ntaub ntawv kev lag luam, laser manufacturing, ntau yam kev lag luam, cov iav motarch, lub teeb pom kev zoo. kev lag luam, cov khoom siv kho kom zoo nkauj, npib, tsom iav qhov muag, thiab lwm yam. Txheej tshuab tau dhau los ua kev sib raug zoo rau hauv tib neeg lub neej.
