Dab tsi yog qhov tshiab ultrasound yoj thev naus laus zis dairly thov?
Ultrasound poob phaus
Siv cov cavitation effect thiab micro-mechanical vibration ntawm ultrasonic transducer, cov rog rog ntau dhau hauv tib neeg daim tawv nqaij tau tawg, emulsified, thiab tawm ntawm lub cev kom ua tiav lub hom phiaj ntawm kev poob phaus thiab hloov pauv. Nov yog thev naus laus zis tshiab tsim nyob rau xyoo 1990 thoob ntiaj teb. Zocch kuv los ntawm Ltalis siv ultrasonic degreasing rau lub txaj thawj zaug thiab ua tiav, teeb tsa ua ntej rau kev phais yas thiab kev zoo nkauj. Tshuab ultrasonic tshem tawm cov rog tau tsim tawm sai sai hauv tsev thiab txawv teb chaws.
Ultrasonic yug me nyuam
Ua ntawv thov kom tsim nyog thiab siv zog ntawm kev kho hluav taws xob ultrasonic rau cog cov noob tuaj yeem ua rau nce cov noob ntawm cov noob, txo tus nqi ntawm cov kab mob thiab lwj, txhawb kev loj hlob ntawm cov noob, thiab nce kev loj hlob ntawm cov nroj tsuag. Raws li cov ntaub ntawv, ultrasound tuaj yeem nce qhov kev loj hlob ntawm qee cov noob cog los ntawm 2 txog 3 zaug.
Ntshav Siab Ntsuas
Ultrasonic transducer yog siv los txais lub siab ntawm cov hlab ntshav. Thaum lub hnab cua nthuav tawm cov hlab ntshav, vim tias qhov kev thov siab siab dua li cov vasodilation siab, lub transducer ultrasonic tsis tuaj yeem hnov lub siab ntawm cov hlab ntshav; thiab thaum lub airbag maj mam deflates, ultrasonic transducer Thaum lub siab ntawm cov hlab ntshav txo qis rau tus nqi, qhov siab ntawm ob mus txog qhov sib npaug. Lub sijhawm no, tus hloov pauv ultrasonic tuaj yeem hnov lub siab ntawm cov hlab ntshav. Qhov siab no yog systolic siab ntawm lub plawv. Ntshav siab tus nqi. Vim tias lub tshuab hluav taws xob sphygmomanometer tshem tawm lub tshuab raj, kev siv zog ntawm cov neeg ua haujlwm kho mob tuaj yeem txo qis.
Telemetry thiab kev tswj chaw taws teeb
Hauv cov tshuaj lom, tshuaj muaj kuab lom thiab lwm yam kev ua phem, tib neeg tsis tuaj yeem ua haujlwm tau thiab yuav tsum tau tswj kom nyob deb; cov hluav taws xob hloov pauv xws li TV, kiv cua hluav taws xob, thiab teeb yuav tsum tau tswj nyob ib puag ncig, thiab cov hloov hluav taws xob ultrasonic tuaj yeem teeb tsa kom xa ultrasonic tsis nyob deb. Tus tau txais kev hloov pauv ntawm qhov kev tswj hwm hloov pauv lub teeb liab suab mus rau hauv lub teeb liab hluav taws xob kom ua qhov hloov pauv.
Kev saib xyuas tsheb
Hauv kev tsav tsheb niaj hnub no, nws yog ib qho tsim nyog yuav tsum tau saib xyuas kev hla thiab suav ntawm cov tsheb txhawm rau txhawm rau nkag siab cov kev ua haujlwm ntawm lub tsheb. Piv txwv li, chaw nres tsheb saib xyuas tsheb tau nruab nrog lub tshuab ntsuas hluav taws xob ultrasonic thiab nws cov cuab yeej pabcuam rau ob lub transceivers. Thaum lub tsheb hla dhau, lub suab mem tes rov los. Tus naj npawb ntawm cov tsheb niaj hnub tuaj yeem tau los ntawm kev suav thiab sib sau ua ke. Nruab ib lub transmitter-receiver transducer nyob tom qab ntawm lub tsheb kom tiv thaiv kev thim rov qab. Kev teeb tsa ntawm tau txais piezoelectric ultrasonic transducers ntawm txoj kev loj kuj tseem tuaj yeem saib xyuas lub suab nrov.
Ntau
Ultrasonic nrug ntsuas cov cuab yeej tseem hu ua tus kav suab. Nws ntsuas lub sij hawm mem tes luv los ntawm lub transceiver nrog ob lub hom phiaj. Lub suab nrov tuaj yeem ntsuas qhov nrug tsis pub dhau 10m, thiab qhov raug tuaj yeem ncav cuag ob peb txhiab leej.
Kev xau kom pom thiab ntsuas roj
Txog cov tshuab siab, ntawm qhov xau, lub dav hlau nrov nrov yog tshwm sim los ntawm qhov sib txawv ntawm sab hauv thiab sab nraud ntawm lub nkoj siab. Cov suab nrov nrov no yog dav heev. Rau cov tshuab tsis muaj zog, cov khoom siv ultrasonic tuaj yeem tso rau hauv qhov kaw thiab tom qab ntawd tau txais los ntawm sab nraum qhov kaw. Feem ntau, qhov ntsuas qhov ntsuas qhov siab me me lossis tsis muaj thaum tsis muaj qhov to, thiab lub teeb liab lub suab nrov yuav nce ntxiv tam sim ntawd ntawm qhov chaw xau. Kev ntsuas cov pa roj av tseem yog ib txoj hauv kev tseem ceeb hauv kev lag luam tshuaj lom neeg. Muaj ntau yam kev nthuav dav rau kev ntsuas kom pom, xws li ntab flowmeters thiab lwm yam. Txawm li cas los xij, qhov txiaj ntsig tseem ceeb ntawm kev siv lub tshuab hloov pauv ultrasonic yog tias nws tsis cuam tshuam qhov ntws ntawm cov kua.
Cov Ntaub Ntawv Sau
Txhawm rau kom paub lub luag haujlwm xws li taug kev dawb hauv qhov chaw thiab paub cov khoom, cov neeg txawj ntse tsis tsuas yog xav tau siv cov transducers ultrasonic rau kev ntsuas nrug thiab kev taw qhia, tab sis kuj xav tau kev lees paub pom. Yog li ntawd, qhov me me ultrasonic transducer array xav tau kom ua tiav ntau yam haujlwm. Qhov no yuav dhau los ua cov ncauj lus tshawb fawb tseem ceeb, nyiam ntau tus kws tshawb fawb los tawm tsam rau nws.
