Abstract: A two-step diffusion method for preparing high-performance dual-main-phase sintered mischmetal-iron-boron magnet belongs to the preparing technical field of rare earth permanent magnet materials. The compositions of the two main phase alloys are RE-Fe—B (RE is Nd or Pr) and (Nd, MM)-Fe—B (MM is mischmetal), respectively. First, PrHoFe strip-casting alloy is used as a diffusion source. Next, a PrHo-rich layer is uniformly coated on the surface of (Nd, MM)-Fe—B hydrogen decrepitation powders. The higher anisotropic fields of Pr2Fe14B and Ho2Fe14B are used to improve the coercivity. Then, the ZrCu strip-casting alloy is used as a diffusion source. A Zr-rich layer is uniformly coated on the surface of the powders after the first-step diffusion, which prevents the growth of the MM-rich main phase grains during the sintering process and the inter-diffusion between the two main phases, thus obtaining high coercivity.

Abstract: A switching method is applied to a terminal that supports WiFi communication on at least two frequency bands. When the terminal and a first Access Point (AP) transmit information by using a first frequency band, a request for establishing a connection between the terminal and a second AP by using a second frequency band is sent to the second AP. When a success message that is fed back by the second AP according to the connection request is received, the terminal establishes a connection with the second AP by using the second frequency band, and then sends, to the first AP, an instruction of breaking a connection between the terminal and the first AP.
