Mekhoa e sa tloaelehang ea Litheko tsa Magnet ea Lefatše (250318)

Mmaraka oa China Spot - Qotsulo ea Letsatsi le Letsatsi ea Lihlahisoa tsa Magnet ea Rare Earth, Feela bakeng sa Reference!

▌Senepe sa Maraka

Pr-Nd Alloy

• Range ea Hona joale: 543 000 - 547 000
• Theko Trend: E tsitsitseng ka ho feto-fetoha ha maemo

Motsoako oa Dy-Fe

• Range ea Hona joale: 1,630,000 - 1,650,000
• Theko Trend: Tlhokahalo e tiileng e tšehetsa lebelo le holimo

Superconducting Magnets ho MRI: Precision & Innovation (598 chars)
Lisebelisoa tsa morao-rao tsa MRI li itšetlehile ka li-coil tsa superconducting tsa niobium-titanium (NbTi) tse pholileng ka helium ea metsi ho hlahisa masimo a 1.5-7T. Khatelo-pele ea bohlokoa:

• Tšimo ea homogeneity: Likhoele tse benyang tse sebetsang li nepahetse ≤0.5ppm ho sebelisa 'mapa oa nako ea sebele oa B₀ (TR=2ms)
• Ho tima tsamaiso: Li-valve tsa liphallelo tse nang le mekhahlelo e mengata li senya matla a 15MJ ho 0.3s nakong ea ho hlōleha ha li-coil
• Cryogenics: Li-cryocoolers tse koetsoeng li boloka 4.2K ka <10⁻⁶ W/㎡ ho lutla ha mocheso

Litekanyetso tsa tšebetso:

• Likhoele tsa Nb₃Sn: Finyella 21T @ 15K (Brookhaven Lab 2024), e nolofalletsang MRI ea holimo-limo
• Sisteme ea Zero-boiloff: Boloka 1500L helium bakeng sa lilemo tse 10+ ka sehatsetsi sa makenete (teknoloji e tsoang ho NASA)
• Litšoantšo tse tsamaisoang ke AI: Thuto e tebileng e haha ​​​​bocha 0.5mm切片图像 ho tsoa ho 50% data e tala (缩短扫描时间42%)

Nyeoe ea indasteri: Sisteme ea Siemens' 7T Terra e fokotsa lerata la acoustic ho 85dB (vs. 110dB常规MRI) ka ho hlakola ho sisinyeha ho sebetsang, ho matlafatsa boiketlo ba mokuli.
