IiNdlela zeXabiso zeMazibuthe yoMhlaba oRare (250318)

Imakethi ye-China Spot-iMathiriyeli yeMagnet yoMhlaba eNqabileyo yonke imihla, ngeReferensi nje!

▌Isifinyezo seMarike

I-Pr-Nd Alloy

• Uluhlu lwangoku: 543,000 - 547,000
• Price Trend: Izinzile kunye nokuguquguquka emxinwa

Ingxubevange yeDy-Fe

• Uluhlu lwangoku: 1,630,000 - 1,650,000
• Price Trend: Imfuno eqinile ixhasa ukunyuka okuphezulu

I-Superconducting Magnets kwi-MRI: Ukuchaneka kunye ne-Innovation (i-598 chars)
Izikena ze-MRI zanamhlanje zithembele kwi-niobium-titanium (NbTi) iikhoyili eziphezulu ezipholileyo nge-helium yolwelo ukuvelisa amasimi e-1.5-7T. Ukuqhubela phambili okubalulekileyo:

• I-homogeneity yentsimi: Iikhoyili ezibengezelayo ezisebenzayo zilungile ≤0.5ppm ukutenxa kusetyenziswa ixesha lokwenyani lemephu ye-B₀ (TR=2ms)
• Cima ulawulo: Iivalve zokunciphisa uxinzelelo lwamanqanaba amaninzi zichitha amandla e-15MJ kwi-0.3s ngexesha lokungaphumeleli kwekhoyili
• I-Cryogenics: Ii-cryocoolers ezivaliweyo zigcina i-4.2K kunye <10⁻⁶ W/㎡ ukuvuza kwe-thermal

Imilinganiselo yokusebenza:

• Iikhoyili ze-Nb₃Sn: Ukufezekisa i-21T @ 15K (i-Brookhaven Lab 2024), eyenza i-MRI ye-ultra-high-field
• Iinkqubo ze-Zero-boiloffGcina i-1500L ye-helium iminyaka eyi-10+ ngefriji yamagnetic (i-NASA-derived tech)
• Umfanekiso oqhutywa yi-AIUkufunda okunzulu kwakha kwakhona 0.5mm切片图像 ukusuka kwi-50% yedatha ekrwada (缩短扫描时间42%)

Imeko yeshishini: Inkqubo ye-Siemens' 7T Terra yehlisa ingxolo ye-acoustic ukuya kwi-85dB (vs. 110dB常规MRI) ngokucinywa kokungcangcazela okusebenzayo, ukomeleza intuthuzelo yesigulana.
