Cov khoom siv rau kev tiv thaiv daim npog ntsej muag ultrasonic

Cov cuab yeej thev naus laus zis muaj qhov tsis txaus ntseeg hauv qab no.

Ib qho yog qhov zoo ntawm cov khoom siv raw khoom tsis tuaj yeem lav,

Cov txheej txheem tseem ceeb ntawm cov txheej txheem tsim khoom thib ob tsis tau ua tiav.

Cov cuab yeej siv lub tshuab npog ntsej muag feem ntau qhia tias tsis muaj kev ruaj ntseg hauv kev ua haujlwm nruab nrab thiab siab zog, thiab cov khoom tsim nyog tus nqi qis. Qee zaum cov khoom siv puas lawm. Xws li cov khoom siv hluav taws xob hloov hluav taws xob, qhov tsis sib xws ntawm cov khoom siv sib nqus siv tsis tuaj yeem ntsuas, sib nqus sib nqus sib nqus sib nqus flux ntom ntom (Bs), sib nqus induction siv (Bm), muaj txiaj ntsig zoo permeability (Ue), qhov seem sib nqus flux ntom ntom (Br), quab yuam quab yuam ( A / M), thiab lwm yam, cov txheej txheem winding yog qhov tsis zoo, thiab cov kev cob qhia hauv tsev no tsis tuaj yeem ua.,
