    摘要： A method and apparatus for separating air by cryogenic rectification in which cooled, compressed and purified air is separated in a distillation column system having higher and lower pressure columns operatively associated with one another in a heat transfer relationship to produce an oxygen-rich liquid stream from the lower pressure column. The oxygen-rich liquid stream is pumped and heated through indirect heat exchange with a compressed heat exchange stream to form a pressurized oxygen product stream. Part of the air is sequentially and successively compressed in booster compressors driven by turboexpanders to form the compressed heat exchange stream while other parts of the air are expanded in turboexpanders driving the booster compressors to form exhaust streams that are introduced into both the higher and lower pressure columns to generate refrigeration.

    摘要： A rare-earth permanent magnetic powder, a bonded magnet, and a device comprising the bonded magnet are provided. The rare-earth permanent magnetic powder is mainly composed of 7-12 at % of Sm, 0.1-1.5 at % of M, 10-15 at % of N, 0.1-1.5 at % of Si, and Fe as the balance, wherein M is at least one element selected from the group of Be, Cr, Al, Ti, Ga, Nb, Zr, Ta, Mo, and V, and the main phase of the rare-earth permanent magnetic powder is of TbCu7 structure. Element Si is added into the rare-earth permanent magnetic powder for increasing the ability of SmFe alloy to from amorphous structure, and for increasing the wettability of the alloy liquid together with the addition of element M in a certain content, which enables the alloy liquid prone to be injected out of a melting device. The average diameter of the rare-earth permanent magnetic powder is in the range of 10-100 μm, and the rare-earth permanent magnetic powder is composed of nanometer crystals with average grain size of 10-120 nm or amorphous structure.
