Nts'etsopele ea Lisebelisoa tsa Magnetostrictive tsa Lefatše tse Rare
Beijing Iron and Steel Research Institute e qalile lipatlisiso tsa eona mabapi le theknoloji ea ho lokisa GMM pejana.Ka 1991, e ne e le ea pele Chaena ho lokisa mekoallo ea GMM le ho fumana patent ea naha.Ka mor'a moo, lipatlisiso tse eketsehileng le ts'ebeliso li ile tsa etsoa ka li-transducer tsa li-acoustic tse nang le maqhubu a tlaase ka tlas'a metsi, fiber optic ho lemoha hona joale, li-transducers tse nang le matla a phahameng a matla a motlakase, joalo-joalo, le tlhahiso e sebetsang hantle ea theknoloji ea GMM le lisebelisoa tse nang le litokelo tse ikemetseng tsa thepa ea bohlale le bokhoni ba selemo le selemo ba tlhahiso. tsa lithane li ile tsa ntlafatsoa.Thepa ea GMM e ntlafalitsoeng ke Univesithi ea Beijing ea Saense le Thekenoloji e lekoa ka likarolo tse 20 ka hare ho naha le matjhabeng, mme ho bile le litholoana tse ntle.Khamphani ea Lanzhou Tianxing e boetse e ntlafalitse mohala oa tlhahiso o nang le bokhoni ba selemo le selemo ba tlhahiso ea lithane, 'me e entse likatleho tse kholo nts'etsopele le ts'ebeliso ea lisebelisoa tsa GMM.
Leha lipatlisiso tsa China mabapi le GMM li qalile e se morao haholo, e ntse e le methating ea eona ea pele ea kholo ea indasteri le nts'etsopele ea ts'ebeliso.Hajoale, China ha e hloke feela ho etsa tsoelo-pele ho theknoloji ea tlhahiso ea GMM, lisebelisoa tsa tlhahiso, le litšenyehelo tsa tlhahiso, empa e boetse e hloka ho tsetela matla ho nts'etsopele ea lisebelisoa tsa kopo ea thepa.Linaha tsa kantle ho naha li nka bohlokoa bo boholo ho kopantseng lisebelisoa tse sebetsang, likarolo le lisebelisoa tsa ts'ebeliso.Thepa ea ETREMA United States ke mohlala o tloaelehileng ka ho fetisisa oa ho kopanngoa ha lipatlisiso le thekiso ea lisebelisoa tsa lisebelisoa le lisebelisoa.Tšebeliso ea GMM e kenyelletsa likarolo tse ngata, 'me batho ba ka hare ho indasteri le bo-rakhoebo ba lokela ho ba le ponelo-pele ea leano, ponelo-pele, le kutloisiso e lekaneng ea nts'etsopele le ts'ebeliso ea lisebelisoa tse sebetsang ka tebello e pharaletseng ea ts'ebeliso lekholong lena la bo21 la lilemo.Ba lokela ho beha leihlo mekhoa ea nts'etsopele ea lefapha lena ka hloko, ba potlakise ts'ebetso ea eona ea indasteri, le ho khothaletsa le ho ts'ehetsa nts'etsopele le ts'ebeliso ea lisebelisoa tsa kopo ea GMM.

GMM e na le sekhahla se phahameng sa ho fetola matla a mochini le motlakase, matla a phahameng a matla, lebelo le phahameng la karabelo, ts'epahalo e ntle, le mokhoa o bonolo oa ho khanna mocheso oa kamore.Ke melemo ena ea ts'ebetso e lebisitseng phetohong ea phetoho lits'ebetsong tsa tlhahisoleseling tsa elektroniki, lits'ebetso tsa kutlo, lits'ebetso tsa vibrate, joalo-joalo.
Tšebeliso ea Lisebelisoa tse Rare Earth Magnetostrictive
Lekholong le lecha la theknoloji le ntseng le tsoela pele ka potlako, lisebelisoa tse fetang 1000 tsa GMM li hlahisitsoe.Libaka tse kholo tsa ts'ebeliso ea GMM li kenyelletsa tse latelang:
