Nws yog ua los ntawm cov khoom siv tawv ceramic. … Thaum submerged nyob rau hauv dej, ib tug ceramic hydrophone tsim me me-voltage signals nyob rau hauv ntau ntau zaus raws li nws yog raug rau underwater suab propagating los ntawm ib qho kev taw qhia.
Hydrophones ua los ntawm dab tsi?
Feem ntau cov hydrophones yog tsim los ntawm khoom piezoelectric. Cov khoom no ua rau cov nqi hluav taws xob me me thaum raug hloov siab. Cov kev hloov siab cuam tshuam nrog lub suab nthwv dej tuaj yeem kuaj pom los ntawm lub piezoelectric caij.
Lub hom phiaj ntawm hydrophones hauv WW1 yog dab tsi?
thawj hydrophones tau tsim nyob rau hauv 1914 los siv thaum lub sij hawm WW1 rau pab submarine crews kom tsis txhob sib tsoo nrog icebergs.
Puas submarines tseem siv hydrophones?
Txij li thaum Tsov Rog Ntiaj Teb Zaum 1 mus txog rau thaum kev qhia txog kev ua haujlwm sonar thaum ntxov xyoo 1920, hydrophones yog tib txoj kev rau submarines los ntes cov hom phiaj thaum submerged; lawv tseem siv tau hnub no.
Puas yog hydrophones transducers?
Ib yam hydrophone muaj a transducer. Qhov no transducer yog qhov tseem ceeb heev rau kev hloov cov suab nthwv dej tuaj rau hauv qhov hluav taws xob hluav taws xob. … Thaum lub tshuab hluav taws xob tuaj yeem ntes cov suab nthwv dej hauv huab cua, nws tsis zoo li cov suab nrov hauv huab cua vim tias nws cov acoustic impedance tau tsim tshwj xeeb rau kev tshawb pom lub suab hauv dej.
