Izinga lokukhula kokuthunyelwa kwe-China kumazwe angaphandle kweemagnethi zomhlaba ezinqabileyo eziya e-United States lehlile ukusuka kuJanuwari ukuya ku-Epreli
Ukususela ngoJanuwari ukuya ku-Epreli, izinga lokukhula kwe-China yokuthunyelwa ngaphandle kweemagnethi ezinqabileyo zomhlaba ezisisigxina e-United States zehlile. Uhlalutyo lwedatha yeenkcukacha-manani lubonisa ukuba ukusuka ngoJanuwari ukuya ku-Epreli ka-2023, ukuthunyelwa kwe-China yeemagnethi ezinqabileyo zomhlaba ezisisigxina e-United States zafikelela kwiitoni ezingama-2195, unyaka nonyaka...Funda ngokugqithisileyo -

Uphando malunga nemiphumo yezinto ezinqabileyo zomhlaba kwi-physiology yezityalo lubonise ukuba izinto ezinqabileyo zomhlaba zinokunyusa umxholo we-chlorophyll kunye ne-photosynthetic rate kwizityalo; Ukukhuthaza ngokubonakalayo ukuhluma kwezityalo kunye nokukhawulezisa ukukhula kweengcambu; Yomeleza umsebenzi wokufunxa ion kunye nephysio...Funda ngokugqithisileyo -
Amaxabiso omhlaba anqabileyo awile kwiminyaka emibini edlulileyo, kwaye imarike kunzima ukuyiphucula kwisiqingatha sokuqala sonyaka. Ezinye iindibano zocweyo ezincinci zemagnethi eGuangdong naseZhejiang ziyekile ...
Imfuno esezantsi yomlambo iyacotha, kwaye amaxabiso omhlaba anqabileyo ehle abuyela kwiminyaka emibini edlulileyo. Ngaphandle kokuphindaphindeka okuncinci kumaxabiso omhlaba anqabileyo kwezi ntsuku zidlulileyo, uninzi lwabangaphakathi kwishishini baxelele iintatheli ze-Arhente yeNdaba yeCailian ukuba uzinzo lwangoku lwamaxabiso omhlaba anqabileyo alunankxaso kwaye kusenokwenzeka ukuba ...Funda ngokugqithisileyo -
Ubunzima ekunyukeni kwamaxabiso oMhlaba oQhelekileyo ngenxa yoKuhla kwireyithi yokuSebenza kwamaShishini weMagnetic Material
Imeko yemarike yomhlaba enqabileyo nge-17 kaMeyi ka-2023 Ixabiso lilonke lehlabathi elinqabileyo e-China libonise ukuguquguquka okunyukayo, okubonakaliswa ikakhulu kunyuso oluncinci lwamaxabiso epraseodymium neodymium oxide, igadolinium oxide, kunye ne-dysprosium iron alloy ukuya kuma-465000 yuan/ itoni, 272000 yuan/uku...Funda ngokugqithisileyo -
Iindlela zokukhupha i-scandium
Iindlela zokukhutshwa kwe-scandium Ixesha elide emva kokufunyanwa kwayo, ukusetyenziswa kwe-scandium akuzange kuboniswe ngenxa yobunzima bayo kwimveliso. Ngokuphucuka okwandayo kweendlela ezinqabileyo zokwahlula izinto zomhlaba, ngoku kukho inkqubo evuthiweyo yokuhamba yokucoca i-scandi ...Funda ngokugqithisileyo -
Ukusetyenziswa okuphambili kwe-scandium
Ukusetyenziswa okuphambili kwe-scandium Ukusetyenziswa kwe-scandium (njengeyona nto isebenzayo, kungekhona i-doping) igxininiswe kwindlela eqaqambileyo kakhulu, kwaye akusiyo ukugqithisa ukuyibiza ngokuthi nguNyana wokukhanya. 1.

Into yomhlaba enqabileyo | I-Ytterbium (Yb)
Ngo-1878, uJean Charles kunye noG.de Marignac bafumanisa into entsha enqabileyo yomhlaba kwi "erbium", ebizwa ngokuba yiYtterbium nguYtterby. Ukusetyenziswa okuphambili kwe-ytterbium ngolu hlobo lulandelayo: (1) Isetyenziswe njengento yokukhusela i-thermal. I-Ytterbium inokuphucula kakhulu ukuxhathisa ukubola kwe-zinc efakwe kwi-electrodeposited ...Funda ngokugqithisileyo -
