Abstract: An ultrasonic osteotome bit, comprising a bit body (1), a bit bar (2) and a bit tip (3). One end of the bit bar (2) is connected to the bit tip (3), and the other end of the bit bar (2) is connected to the bit body (1). The bit tip (3) is of a prism or substantially prism structure with the cross section of a polygonal structure, and the bit tip (2) has at least two cutting faces of different cutting widths. The bit is provided with a liquid flow hole (41), and the bit tip (3) is provided with a knurled structure that extends from a foremost end face of the bit tip (3) towards the bit bar (2) to form a file-type bit. The ultrasonic osteotome bit not only meets the requirement of a surgeon for the accuracy of bone cutting width, but also saves the time required to replace bits of different widths, thereby improving the surgical efficiency.

Abstract: The present invention discloses a high-strength R-T-B rare earth permanent magnet and a preparation method thereof. The magnet contains 0.3-1.5 wt. % of an element Zr, and a cast strip prepared through vacuum induction melting and melt spinning is treated at a high temperature to make the element Zr therein precipitate in a form of fibrous Zr compounds from R-rich phases, and the fibrous Zr compounds can be uniformly mixed with magnetic powder after hydrogen decrepitation and powder jet milling and mixing, and gradually grow into rod-like Zr compounds existing in the R-rich intergranular phases during the sintering of a green compact. By adjusting the content of the element Zr, sintering temperature and time and other process parameters, the morphology, size and distribution of Zr compounds can be effectively controlled, and the mechanical properties of the magnet can be improved by strengthening the R-rich intergranular phases without deteriorating the magnetic properties of the magnet.

Abstract: The disclosed online transaction method and system uses payment platform acting as an intermediary agent between the merchant and the shipping company to handle the payment. While the payment platform receives payment from the shipping company, the merchant receives payment from the payment platform. The method and system do not require buyers to use the payment method provided by an intermediary transaction platform to make a payment. Instead, the buyer may pay directly to the shipping company. Unlike conventional transaction method based on COD, however, the disclosed online transaction method and system centrally manage a logistics platform or multiple logistics operations run by logistics companies. The merchant does not receive the payment from the logistics company, but rather receive the payment from a centralized payment platform to ensure secure and fast payment.
