Ikhwalithi ephezulu ye-NdFeB Magnet evela empumalanga
Incazelo emfushane:
I-hangzhou uzibuthe amandla we-NdFeB Magnet, uzibuthe we-smco, i-rotor, umhlangano uzibuthe, umhlangano we-halbach
Ikhwalithi ephezulu ye-NdFeB Magnet evela empumalanga
Amandla angaqondakali aseMpumalanga,
ifa izinkulungwane zeminyaka, eyatuswa uConfucius
Abantu abavelele
isikhathi esifanele nendawo efanele
Emibhalweni yeNkathi Yentwasahlobo kanye Nekwindla kanye Nenkathi Yamazwe Alwayo, izakhiwo eziheha insimbiozibuthezarekhodwa ngokuphindaphindiwe.Isibonelo, "itshe kazibuthe libiza insimbi" ku "Lu Shi Chun Qiu" eyabhalwa ngekhulu lesithathu BC, futhi "itshe kazibuthe libiza inaliti" ku "Guiguzi" elingekude komunye nomunye.Ngalesi sikhathi, i-magnetism cishe yayivame ukubonakala futhi iqhathaniswa nokukhangwa kukamama onothando ezinganeni zakhe.
UGao Yao Wozalo LwaseMpumalanga Han wathi esichasiselweni sakhe esithi "Lu Shi Chun Qiu": Itshe lingumama wensimbi, kodwa kunamatshe anomusa nangenamusa.Itshe elinomusa lingakhanga izingane zalo (insimbi), kodwa itshe elingenamusa alikwazi ukulidonsa..Ngakho-ke, ngaphambi kobukhosi bakwaHan, odonsa babebhalwa ngokuthi "Ci Shi", okusho ukuthi "Itshe Lomusa".
Kamuva, abantu basebenzise omazibuthe nakanjani ukuze bazame ukuheha ezinye izinsimbi noma izinto.Waba yini umphumela?
Incwadi ethi "Huainanzi" eyabhalwa eNtshonalanga Han Dynasty yabhala: "Uma itshe elinomusa lingaxhuma insimbi, kuyoba nzima ukulisebenzisa ukuhola amathayili.""Ayikwazi ukuxhuma nethusi."Ngesikhathi seMibuso Emithathu, omunye wathi: "Itshe lomusa alinakugoba."Okubizwa ngokuthi "izinaliti ezigobile" cishe kubhekisela ezinaliti ezenziwe ngezinsimbi ezifana negolide, isiliva, nethusi, okuyiqiniso ukuthi azikhangwa yizibuthe.
Lawa marekhodi abonisa ukuthi i-Han Dynasty yaqaphela ukuthi odonsa bangadonsa insimbi kuphela kodwa hhayi ezinye izinto.Lena inqubekelaphambili kancane.Siyazi ukuthi omazibuthe bangadonselana kuphela ensimbi, kodwa uma omazibuthe besondelene, isimo siba nzima kakhulu.Izibuthe zihlala zinezinti ezimbili, enye ibizwa ngokuthi i- south pole enye ibizwa ngokuthi i-north pole.Ngaleso sikhathi, kwakukhona an isazi se-alchemist okuthiwa uLuan Da owenza omazibuthe ababili, ababebukeka njengezicucu ze-chess futhi besondelene.Kuthiwa abakwazanga ukuheha kuphela ("khansela bodwa"), kodwa futhi "baxoshana ngokungapheli", okungukuthi, baxoshane.Leli yiqhinga elibizwa nge-"fighting chess".Wenze leli qhinga kuMbusi uWu wobukhosi bakwaHan,futhiumbusi wahlekiswa, ngakho wathola isikhundla esisemthethweni se "Five-profit General".
