Lub ntsuas cua sov ultrasonic ua lub luag haujlwm tseem ceeb heev hauv kev lag luam cua sov, ces koj puas paub yuav ua li cas thiaj paub qhov txawv ntawm lub ntsuas cua sov ultrasonic zoo lossis phem? Ua ntej tshaj plaws, peb xaiv cov chaw tsim khoom tsim nyog, qhov thib ob, peb tuaj yeem txheeb xyuas qhov zoo ntawm lub ntsuas cua sov ultrasonic los ntawm cov hauv qab no, cia peb muab cov lus qhia ntxaws ntxaws rau koj:
Kev rhiab heev: Kev rhiab heev yog qhov sib piv ntawm kev hloov me me hauv cov zis ntawm lub cuab yeej rau kev hloov me me hauv cov tswv yim hauv lub xeev ruaj khov; Qhov no tseem ceeb heev;
Kev ua dua tshiab: qhov kev ua dua tshiab uas tau hais ntawm no feem ntau yog hais txog qib kev tsis sib xws ntawm tus nqi uas tau qhia nyob rau hauv tib qho xwm txheej, thiab qib me dua, qhov tseeb siab dua;
Qhov tseeb: raws li lub teb chaws cov kev cai ntawm qhov yuam kev sib piv ntawm tus nqi txheem kem rau qib. Nws qhia meej qhov yuam kev sib piv siab tshaj plaws ntawm txhua qib ntawm cov cuab yeej siv raws li cov xwm txheej ntawm kev siv ntsuas yuav tsum tsis pub tshaj tus nqi;
Linearity: Qhov yuam kev nonlinear, rau qhov theoretical linear input thiab output characteristic curve ntawm lub cuab yeej, qhov tseeb characteristic curve feem ntau deviates los ntawm linear relationship. Qhov feem pua ntawm qhov sib txawv siab tshaj plaws ntawm lawv piv rau qhov ntau yam hu ua linearity;
Kev Ruaj Ntseg: Qhia txog kev ua tau zoo ntawm cov nqi uas tsis hloov pauv raws sijhawm thiab cov xwm txheej ntawm kev siv. Kev ruaj ntseg ntawm lub sijhawm yog qhia ua kev ruaj ntseg, uas yog, qhov ntau ntawm kev hloov pauv random hauv tus nqi dhau ib lub sijhawm. Qhov cuam tshuam ntawm kev hloov pauv hauv cov xwm txheej ntawm kev siv yog qhia ua qhov yuam kev ntawm qhov cuam tshuam. Piv txwv li, qhov cuam tshuam ntawm qhov kub thiab txias ib puag ncig yog qhia los ntawm qhov ntau npaum li cas tus nqi qhia hloov pauv rau txhua qhov kev hloov pauv ntawm qhov kub thiab txias.
