Xyuas seb cov yeeb nkab puas muaj kua dej puv. Sim siv txoj kev Z rau kev teeb tsa transducer (Yog tias cov yeeb nkab nyob ze rau phab ntsa, lossis nws tsim nyog yuav tsum teeb tsa cov transducers rau ntawm cov yeeb nkab ntsug lossis inclined nrog cov dej ntws mus rau sab saud es tsis txhob ntawm cov yeeb nkab kab rov tav).
Ua tib zoo xaiv ib ntu yeeb nkab zoo thiab ntxuav nws kom huv si, muab cov tshuaj sib txuas rau ntawm txhua qhov chaw transducer (hauv qab) thiab teeb tsa lub transducer kom raug. Maj mam thiab me ntsis txav txhua lub transducer ncig qhov chaw teeb tsa kom txog thaum pom lub teeb liab siab tshaj plaws. Ceev faj kom qhov chaw teeb tsa tshiab tsis muaj qhov loj hauv yeeb nkab thiab cov yeeb nkab sib npaug (tsis yog sib npaug) kom cov suab tsis dhia tawm sab nraud ntawm thaj chaw uas tau npaj tseg.
Rau cov yeeb nkab uas muaj cov nplai tuab sab hauv lossis sab nraud, sim ntxuav cov nplai tawm, yog tias nws nkag tau los ntawm sab hauv. (Ceeb Toom: Qee zaum txoj kev no yuav tsis ua haujlwm thiab kev xa suab tsis tuaj yeem ua tau vim muaj ib txheej nplai ntawm cov transducers thiab cov yeeb nkab sab hauv phab ntsa)
