Ultrasonic e fetohile sebaka sa lipatlisiso lefatšeng ka bophara ka lebaka la tlhahiso ea eona ka ho fetisa boima, ho fetisa mocheso le lik'hemik'hale.Ka nts'etsopele le ho tsebahala ha lisebelisoa tsa matla a ultrasonic, tsoelo-pele e itseng e entsoe ka indasteri ea Europe le Amerika.Nts'etsopele ea mahlale le thekenoloji naheng ea China e fetohile thuto e ncha e fapaneng - sonochemistry.Tsoelopele ea eona e susumelitsoe ke mosebetsi o mongata o entsoeng ka khopolo le tšebeliso.
Leqhubu le bitsoang ultrasonic wave ka kakaretso le bua ka leqhubu la acoustic le maqhubu a 20k-10mhz.Matla a ts'ebeliso ea eona lefapheng la lik'hemik'hale haholo-holo a tsoa ho ultrasonic cavitation.Ka leqhubu le matla la ho sisinyeha le microjet e nang le lebelo le holimo ho 100m / s, sekhahla se phahameng sa sekhahla sa leqhubu le microjet se ka hlahisa li-radicals tsa hydroxyl ka tharollo ea metsi.Litlamorao tse tsamaellanang tsa 'mele le tsa lik'hemik'hale haholo-holo ke litlamorao tsa mochini (acoustic shock, shock wave, microjet, joalo-joalo), litlamorao tsa mocheso (mocheso o phahameng oa lehae le khatello e phahameng, ho phahama ha mocheso ka kakaretso), litlamorao tsa optical (sonoluminescence) le litlamorao tsa ts'ebetso (hydroxyl radicals ke e hlahisoang ka tharollo ea metsi).Liphello tse 'nè ha li arohane, Ho e-na le hoo, li sebelisana le ho khothalletsana ho potlakisa ts'ebetso ea ho itšoara.
Hajoale, lipatlisiso tsa tšebeliso ea ultrasound li pakile hore ultrasound e ka kenya tšebetsong lisele tsa baeloji le ho khothaletsa metabolism.Low intensity ultrasound e ke ke ea senya sebopeho se felletseng sa sele, empa e ka ntlafatsa ts'ebetso ea metabolic ea sele, ea eketsa ho kenella le ho khetha ha lera la sele, le ho khothaletsa ts'ebetso ea biological catalytic ea enzyme.Leqhubu le matla le phahameng la ultrasonic le ka senya enzyme, la etsa hore colloid ka seleng e kene ka har'a flocculation le sedimentation ka mor'a hore ho be le oscillation e matla, 'me e be liquefy kapa emulsify gel, kahoo e etsa hore libaktheria li lahleheloe ke mosebetsi oa likokoana-hloko.Holim'a moo.Mocheso o phahameng oa hang-hang, phetoho ea mocheso, khatello e phahameng ea hang-hang le phetoho ea khatello e bakoang ke ultrasonic cavitation e tla bolaea libaktheria tse ling ka har'a metsi, e thibele kokoana-hloko, esita le ho senya lerako la sele ea likokoana-hloko tse ling tse nyenyane tsa letšoao.Higher intensity ultrasound e ka senya lerako la sele le ho lokolla lintho tse ka seleng.Liphello tsena tsa likokoana-hloko li boetse li sebetsa ho phello ea ultrasound ho sepheo.Ka lebaka la ho khetheha ha sebopeho sa lisele tsa algal.Hape ho na le mokhoa o khethehileng oa ho hatella le ho tlosoa ha algae ea ultrasonic, ke hore, mokotla oa moea o ka seleng ea algal o sebelisoa e le nucleus ea cavitation ea bubble ea cavitation, 'me mokotla oa moea o robehile ha bubble ea cavitation e robehile, e fellang ka hore selelu sa algal ho lahleheloa ke matla a ho laola ho phaphamala.
