Hauv kev ntsuas qhov tseeb, lub profilometer yog cov khoom siv tseem ceeb rau kev tau txais cov ntaub ntawv siab, thiab lub hauv paus, ua ib qho tseem ceeb ntawm profilometer, nws lub peev xwm los tiv thaiv kev cuam tshuam electromagnetic ncaj qha cuam tshuam rau qhov tseeb ntawm cov txiaj ntsig ntsuas. Ntawm ntau yam ntaub ntawv hauv paus, granite thiab cam khwb cia hlau yog cov kev xaiv sib txawv. Piv nrog cov hlau cam khwb cia profilometer hauv paus, granite profilometer hauv paus tau pom tias muaj txiaj ntsig zoo hauv kev tshem tawm kev cuam tshuam electromagnetic thiab tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev ntsuas qhov tseeb.
Kev cuam tshuam ntawm kev cuam tshuam electromagnetic rau kev ntsuas ntawm profilometers
Hauv kev lag luam niaj hnub no, kev cuam tshuam hluav taws xob muaj nyob txhua qhov chaw. Txij li cov hluav taws xob hluav taws xob uas tsim los ntawm cov khoom siv loj ua haujlwm hauv lub chaw ua haujlwm mus rau kev cuam tshuam teeb liab los ntawm cov khoom siv hluav taws xob nyob ib puag ncig, thaum cov teeb liab cuam tshuam no cuam tshuam rau lub profilometer, lawv yuav ua rau muaj kev hloov pauv thiab kev hloov pauv hauv cov ntaub ntawv ntsuas, thiab txawm tias ua rau kev txiav txim siab tsis raug ntawm lub kaw lus ntsuas. Rau kev ntsuas contour uas xav tau qhov tseeb ntawm micrometer lossis txawm tias nanometer theem, txawm tias kev cuam tshuam hluav taws xob tsis muaj zog tuaj yeem ua rau cov txiaj ntsig ntsuas poob kev ntseeg siab, yog li cuam tshuam rau cov khoom zoo thiab kev ua haujlwm ntau lawm.
Qhov teeb meem cuam tshuam electromagnetic ntawm lub hauv paus hlau cam khwb cia
Cov hlau cam khwb cia yog cov khoom siv ib txwm muaj rau kev tsim cov hauv paus thiab siv dav vim nws tus nqi qis thiab cov txheej txheem casting laus. Txawm li cas los xij, cov hlau cam khwb cia muaj cov hluav taws xob zoo, uas ua rau nws yooj yim rau electromagnetic induction hauv ib puag ncig electromagnetic. Thaum lub teb electromagnetic tso tawm los ntawm qhov chaw cuam tshuam electromagnetic sab nraud ua rau lub hauv paus hlau cam khwb cia, ib qho tam sim no induced yuav tsim tawm hauv lub hauv paus, tsim ib qho electromagnetic eddy tam sim no. Cov electromagnetic eddy tam sim no tsis yog tsuas yog tsim cov teb electromagnetic theem nrab, cuam tshuam nrog cov teeb liab ntsuas ntawm profilometer, tab sis kuj ua rau lub hauv paus kub, ua rau muaj kev hloov pauv thermal thiab cuam tshuam ntxiv rau qhov tseeb ntawm kev ntsuas. Tsis tas li ntawd, cov qauv ntawm cov hlau cam khwb cia yog xoob thiab tsis tuaj yeem tiv thaiv cov teeb liab electromagnetic, tso cai rau electromagnetic cuam tshuam kom yooj yim nkag mus rau hauv lub hauv paus thiab ua rau cuam tshuam rau cov voj voog ntsuas sab hauv.
Qhov zoo ntawm kev tshem tawm electromagnetic cuam tshuam ntawm lub granite profilometer puag
Cov khoom siv rwb thaiv tsev ntuj
Granite yog ib hom pob zeb ntuj. Nws cov pob zeb sab hauv yog crystallized ze ze thiab cov qauv yog ntom. Nws yog ib qho insulator zoo. Tsis zoo li cov hlau cam khwb cia, granite yog yuav luag tsis-conductive, uas txhais tau tias nws yuav tsis tsim electromagnetic eddy currents hauv ib puag ncig electromagnetic, fej txwm zam cov teeb meem cuam tshuam los ntawm electromagnetic induction. Thaum lub teb electromagnetic sab nraud ua haujlwm rau lub hauv paus granite, vim nws cov khoom insulating, lub teb electromagnetic tsis tuaj yeem tsim lub voj voog hauv lub hauv paus, yog li ntawd txo qhov cuam tshuam rau lub kaw lus ntsuas profilometer.
Kev ua tau zoo heev ntawm kev tiv thaiv
Qhov qauv ntom ntawm granite muab nws nrog qee qhov peev xwm tiv thaiv hluav taws xob. Txawm hais tias granite tsis tuaj yeem thaiv cov teeb liab hluav taws xob zoo li cov ntaub ntawv tiv thaiv hlau, nws tuaj yeem tawg thiab nqus cov teeb liab hluav taws xob los ntawm nws tus kheej cov qauv, yog li ua rau lub zog ntawm kev cuam tshuam hluav taws xob tsis muaj zog. Tsis tas li ntawd, hauv kev siv tiag tiag, lub hauv paus granite profilometer kuj tseem tuaj yeem ua ke nrog cov qauv tiv thaiv hluav taws xob tshwj xeeb, xws li ntxiv cov txheej tiv thaiv hlau, thiab lwm yam, kom txhim kho nws cov nyhuv tiv thaiv hluav taws xob thiab muab qhov chaw ua haujlwm ruaj khov dua rau lub kaw lus ntsuas.
Cov khoom siv lub cev ruaj khov
Ntxiv rau qhov tshem tawm cov teeb meem electromagnetic ncaj qha, cov khoom ruaj khov ntawm granite kuj tseem pab txhawb rau kev txhim kho lub peev xwm tiv thaiv kev cuam tshuam ntawm profilometer. Granite muaj cov coefficient qis heev ntawm thermal expansion thiab tsis tshua muaj kev hloov pauv thaum qhov kub hloov pauv. Qhov no txhais tau tias thaum muaj kev cuam tshuam electromagnetic yuav ua rau muaj kev hloov pauv kub hauv zos, lub hauv paus granite tseem tuaj yeem tswj tau cov duab thiab qhov loj me ruaj khov, ua kom ntseeg tau qhov tseeb ntawm qhov ntsuas thiab zam kev ua yuam kev ntsuas ntxiv vim yog qhov hloov pauv hauv paus.
Niaj hnub no, hauv kev nrhiav kev ntsuas qhov tseeb siab, cov hauv paus granite profilometer, nrog lawv cov khoom rwb thaiv tsev ntuj, kev ua haujlwm zoo heev thiab cov khoom ruaj khov, zoo dua li cov hauv paus hlau cam khwb cia profilometer hauv kev tshem tawm kev cuam tshuam electromagnetic. Kev xaiv profilometer nrog lub hauv paus granite tuaj yeem tswj kev ntsuas ruaj khov thiab raug hauv cov chaw electromagnetic nyuaj, muab kev lees paub kev ntsuas txhim khu kev qha rau cov lag luam nrog cov kev xav tau siab heev xws li kev tsim khoom siv hluav taws xob, kev ua haujlwm kho tshuab precision, thiab aerospace, thiab pab cov tuam txhab txhim kho cov khoom zoo thiab kev sib tw.
