摘要:
The disclosure discloses a method for transmitting and receiving multimedia information and a terminal. The method for transmitting multimedia information includes: dividing multimedia information to be transmitted into multiple information segments; combining the information segments to obtain multiple messages, wherein each of the information segments includes a position identification of the information segment in the multimedia information to be transmitted; in addition, a length of each of the messages is less than or equal to a predetermined length, and each of the messages contains at least one information segment; and sending some or all of the multiple messages to a receiver. By means of the disclosure, a more complete message can be obtained, and multimedia information can be transmitted by lesser messages, so that a cost of a user is reduced and a network burden is alleviated.

Provided are a coated cobalt powder and a preparation method thereof, the coated cobalt powder consisting of cobalt powder, and paraffin wax, polyethylene glycol or polyethylene coated on the outer surface of the cobalt powder. Using the coated cobalt powder to replace traditional cobalt powder as the raw material for preparing hard alloys, the dusts generated during production can be reduced, and the environment in a production shop can be improved; simultaneously, the paraffin wax, the polyethylene glycol or the polyethylene coated on the surface of the cobalt powder can effectively prevent the cobalt powder from being oxidized by the oxygen or water vapor in the air, thus improving the quality of the cobalt powder. The preparation process of the coated cobalt powder is free from contamination and the coated cobalt powder is suitable for industrialized production.

A nut assembly includes a nut and an carrier. The nut defines a number of latching grooves. The carrier includes a planar board and a number of flexible holding elements protruding from the planar board. Each flexible holding element is releasably latched in one of the latching grooves to latch the carrier to the nut. The carrier is capable of moving relative to the nut from a first state to a second state, so the flexible holding elements slide out of the latching grooves to release the carrier from the nut.

A composite rotary-delivery worktable for use in an air container detection system, which is attached to a scanning passage of an air container diction system, said composite rotary-delivery worktable comprising a delivery assembly for carrying and delivering said air container; and a rotary assembly rotatable with a rotation axis, wherein said delivery assembly is attached to said rotary assembly such that said delivery assembly is rotatable with said rotary assembly when said rotary assembly rotates. The composite rotary-delivery worktable of this invention enables large-scale air containers to not only pass the scanning passage but also rotate freely within the scanning passage. This makes it possible to keep the scanning system fixed and stationary, thereby increasing the working reliability of the scanning system and reducing the design difficulty and complexity of the scanning system.
