Ultrasound ke mofuta oa leqhubu la elastic mechanical ka har'a lintho tse bonahalang.Ke sebopeho sa maqhubu.Ka hona, e ka sebelisoa ho bona tlhahisoleseling ea fisioloji le ea pathological ea 'mele oa motho, ke hore, tlhahlobo ea ultrasound.Ka nako e ts'oanang, e boetse ke mofuta oa matla.Ha tekanyo e itseng ea ultrasound e ata ka har'a lintho tse phelang, ka ho sebelisana ha tsona, e ka baka liphetoho mosebetsing le sebopeho sa lintho tse phelang, ke hore, ultrasonic biological effect.

Liphello tsa ultrasound liseleng haholo-holo li kenyelletsa phello ea mocheso, phello ea cavitation le phello ea mechine.Phello ea mocheso ke hore ha ultrasound e hasana bohareng, khohlano e sitisa ho sisinyeha ha molek'hule e bakoang ke ultrasound le ho fetola karolo ea matla hore e be mocheso o phahameng oa sebaka (42-43 ℃).Hobane mocheso o kotsi o bolaeang oa lisele tse tloaelehileng ke 45.7 ℃, 'me kutlo ea lithane tsa Liu e ruruhileng e phahame ho feta ea lisele tse tloaelehileng, metabolism ea lisele tse ruruhileng tsa Liu e ea senyeha ka mocheso ona,' me motsoako oa DNA, RNA le protheine lia ameha. , Kahoo ho bolaea lisele tsa mofetše ntle le ho ama lisele tse tloaelehileng.

Phello ea cavitation ke hore tlas'a mahlaseli a mahlaseli a kotsi, li-vacuoles li thehoa linthong tse phelang.Ka ho thothomela ha li-vacuoles le ho phatloha ho matla ha tsona, ho hlahisoa khatello ea ho kuta le moferefere, e leng ho etsang hore Liu a ruruhe mali, ho qhalana ha lisele le necrosis.

Ho phaella moo, ha bubble ea cavitation e robeha, e hlahisa mocheso o phahameng hang-hang (hoo e ka bang 5000 ℃) le khatello e phahameng (ho fihlela ho 500 ℃) × 104pa), e ka hlahisoang ke ho arohana ha mocheso oa mouoane oa metsi OH radical le H atom, ka OH. radical le The redox reaction e bakoang ke H atom e ka lebisa ho senyeha ha polymer, ho se sebetse ha enzyme, peroxidation ea lipid le ho bolaea lisele.
