Cov kev paub yooj yim thiab txij nkawm kev paub ntawm kev soj ntsuam ultrasound
Ultrasound sojntsuam tseem hu ua piezoelectric transducer: tus transducer yog qhov tseeb nyob rau hauv kev sojntsuam, thiab cov khoom yog piezoelectric ceramic khoom, yog li cov kev sojntsuam ultrasonic tseem hu ua transducer.
Tus qauv ntawm kev sojntsuam ultrasound
Tus qauv: suab lub taub hau iav, txuam txheej, array khoom, thaub qab, plhaub, cable, hnab riam, txuas
Acoustic lens kev puas tsuaj
Suab acoustic lens tshem tawm, thiab qhov tshwm sim ntawm tilted yuav cuam tshuam qhov kev xa / txais ntawm cov cim ultrasonic, uas tuaj yeem ua rau raug mob hnyav
Sib phim txheej muaj nuj nqi:
tuaj yeem hloov qhov kev cuam tshuam ntawm kev sib raug zoo ntawm cov xov xwm pem hauv ntej thiab tom qab, thiaj li ua kom sib kis ntawm cov kis, kom lub suab zog tuaj yeem ua kom zoo ntawm cov piezoelectric wafer thiab cov nqaij mos ntawm tib neeg lub cev, uas tuaj yeem txhim kho qhov rhiab ntawm transducer, dav nws cov zaus zaus, thiab txo qhov tsis sib txawv.
Thaub:
Muaj nuj nqi ntawm suab haum. Txij li cov khoom siv hluav taws xob emits suab tsis nyob rau hauv ob qho kev qhia, ib sab emits rau tib neeg lub cev, tab sis lwm sab emits mus rau kev sojntsuam. Txhawm rau txhawm rau tiv thaiv kev cuam tshuam, lub suab tsis tso tawm mus rau qhov kev sojntsuam yuav tsum tau lim tawm.
Tiv thaiv:
muaj nuj nqi cuam tshuam nrog cuam tshuam nrog suab nrov
array caij
Array keeb kwm: tseem hu ua piezoelectric ceramics
Cov khoom siv: Raws li lub npe txhais tau hais tias, muaj cov khoom siv hlau uas yog hu ua lead zirconate titanate ntawm lub ceramic, thiab cov khoom tseem ceeb yog hu ua hluav taws xob sau.
lub plhaub sab nraud
Plhaub:
Lub plhaub tawg thiab ua rau puas tsuaj: kev cuam tshuam tshwm sim, thiab tus muab nkag rau, ua rau cov khoom sib txuas mus ua rau oxidize, corrode, thiab cuam tshuam cov hlau txuas
Txoj hlua npog txoj hlua yog hle tawm
Thaum siv lub laub, lub hau ntawm cov kev sojntsuam cable tau nias los ntawm lub log ntawm lub laub. Yog hais tias lub cable raug txiav tawm thiab cov txheej thaiv cov xov thaiv tau txiav tawm, lub suab nrov thaiv kev ua haujlwm yuav raug txo kom tsawg, thiab cov duab yuav ua suab nrov.
Tom qab tsim los mus rau theem tsis siv tau.
hnab riam
Hom plooj txig tawg, tawg, thiab ua kom tiav
Lub hnab riam yog txhawm rau qhwv lub qhov sib txuas feem ntawm lub cable thiab lub plhaub coj los tiv thaiv lub qhov txuas thiab tiv thaiv lub suab nrov. Yog tias lub hnab riam tawg lossis tawg, qhov ua kom nrov nrov yuav ua rau tsawg dua, thiab cov duab yuav tawm suab nrov, uas yuav ua rau lub chaw kho mob tsis raug.
Nws kuj tsis yooj yim rau kev kuaj mob ultrasound.
Cov xov hluav taws xob tsis zoo txuas thiab lub kaw lus txuas ntsaws muaj qhov tsis zoo, uas yuav ua rau cov duab tsis zoo tsis zoo, nws yuav tsis ua haujlwm.
Ceev faj thaum siv kev sojntsuam
Xim yuav tsum tau them rau qhov kev sojntsuam:
1, kub
2, av noo
3, ib puag ncig (ntaub, ntawv, thiab tus kheej)
4, txuas tus neeg sawv cev (saib xyuas kom zoo kom tsis txhob xeb)
5. Los tiv thaiv nas thiab kab laum
Saib xyuas ntawm cov khoom siv ultrasound:
1. Lub zog fais fab: qhov hluav taws xob tsis pub dhau lub teev tshwj xeeb lossis rho tawm 10, ntxiv rau cov kev tswj kev huv huv lub zog, thiab kev ywj pheej mov
2, ib txwm tshuab pliav (tiv thaiv luv Circuit Court)
Hloov cov kev sojntsuam: tus tswv tsev yuav tsum khov lossis kaw
