Dab tsi yog qhov zoo ntawm ultrasonic nqus nqus dej?

Nyob rau hauv cov ntaub ntawv ntawm tsawg zaus, lub sij hawm rau kua kom compressed thiab ncab ua ntev dua; Yog li ntawd, lub sijhawm thiab ntim ntawm cavitation ntau tiam yog tseem ntev dua, thiab cov kev cuam tshuam yuam kev tsim tawm thaum loj me me ntawm cavitation npuas. Yog li ntawd, qhov qis dua qhov zaus, lub zog ua kom lub cavitation. Qhov ntau zaus peb siv rau kev ntxuav khoom lag luam feem ntau tsawg dua 60khz, thiab ntau ntawm lawv ntawm 20 thiab 40kHz. Siv ntau zaus txog 20kHz, ib qho me me ntawm cavitation npuas tuaj yeem tau txais, tab sis muaj cov cav sib txawv thiab cov suab nrov. Nws tuaj yeem siv los ntxuav cov neeg ua haujlwm zoo nrog lub zog ua kom muaj zog ntawm cov npoo ntawm cov khoom loj thiab cov khoom ntawm cov khoom. Ntawm ib zaus txog 40kHz, hauv qab lub suab siab, tus naj npawb ntawm cov cavitation hnyav tsim tawm thaum tawg yog me me, thiab lub peev xwm loj, thiab nkag mus rau lub peev xwm yog muaj zog. Nws yog qhov tsim nyog rau cov haujlwm ua haujlwm nrog cov chaw muag khoom plig, cov dig taub, av thiab tsis muaj zog saum npoo tsev.
