Iyunithi yokucindezela komsindo yi-Pa (Pa), futhi ubukhulu bayo bubonisa amandla egagasi lomsindo, okungukuthi, amandla we-wave wave of propagation. Uma ukucindezela komsindo kukhulu, kukhulu ukushuba kwe-ultrasound namandla adluliswayo anamandla. Njengamanje ingelinye lamanani abonakalayo abalulekile avame ukusetshenziselwa ukuchaza izakhiwo zamagagasi omsindo. Ngokukala ingcindezi yomsindo, amanye amanani abonakalayo afana nesivinini sezinhlayiyana angatholakala ngokungaqondile.
Ngesikhathi sokusatshalaliswa kwamagagasi e-longitudinal endaweni enwebekayo, ukucindezela kwamachashazi aphakathi kuyashintsha ngokuhamba kwesikhathi, futhi ukuminyana kwamachashazi aphakathi nendawo kuminyene futhi kuncane. Ngokomgomo wokuhlanganisa, singacabanga ngesisetshenziswa esiqhubekayo njengoba sakhiwe izici eziningi zevolumu encane ezixhumene kakhulu ze-dV. I-medium ku-elementi yevolumu enjalo i-dV ingabuye ibhekwe njengendawo enkulu enesisindo se-ρdV. ρ ukuminyana kwendawo ephakathi, okuyinani eliguqukayo ngesikhathi nendawo ngaphansi kwesenzo samaza omsindo. Ngemuva kokuthi isici sevolumu i-dV iphazanyiswe amagagasi omsindo, ingcindezi iyashintsha isuka ku-p0 iye ku-p1, khona-ke ukucindezela okwedlulele okubangelwa ukuphazamiseka kwegagasi lomsindo kubizwa ngokuthi ingcindezi yomsindo: p=p1- p0
Ngenxa ye-wavelength emfushane kanye nemvamisa ephezulu yamagagasi e-ultrasonic, amandla anawo makhulu kakhulu, angabangela umphumela obalulekile wokucindezela umsindo ezinhlayiyeni ze-medium.
Isicelo: Isicelo se-Ultrasonic ekudleni: i-ultrasonic blade, umshini wokusika we-ultrasonic
