The invention relates to a method for detecting the maximum transmission unit of path, which is characterized in that: each middle node of node chain from the force source node to the target node, should process the data report of maximum transmission unit of the detecting path sent from the source node to the target node; when the middle node receives the data report, to display the maximum transmission unit information in said data report; and when the target node receives the data report, sending the maximum transmission unit information to the source node; and the source node, based on received information, confirms the path maximum transmission unit of the chain from it to the target node. The invention can quickly and accurately confirm PMTU, to confirm the best throughout of network, and avoid loss and retransmission, to improve the network safety.

The invention discloses a gear with the function of anti-vibration and wear resistance, which comprises a gear main body, a tooth assembly is arranged on the outside of the gear main body, a connecting convex ring is arranged on the inside of the gear main body, and the gear main body and the connecting convex ring are integrated Structure, the inner side of the connecting convex ring is provided with a buffer inner ring, the middle part of the buffer inner ring is provided with a connecting shaft hole, the inside of the connecting convex ring is provided with a buffer groove, the outer surface of the buffer inner ring is provided with a main buffer block, and the buffer inner ring It has an integrated structure with the main buffer block. The two side walls of the buffer tank are provided with main springs, and the two sides of the main buffer block are pressed against the main springs; the invention uses the designed connecting convex ring and buffer inner ring to be used in gears. When a sudden force is applied, the main buffer block on the buffer inner ring can be used to slide and compress the main spring in the buffer groove, and the elastic force of the main spring can be used for buffering, thereby reducing the impact on the gear when it starts and stops, and reducing the impact of vibration on the gear during operation. Fatigue damage from gears.

The invention relates to an optical fiber connector assembly, and the assembly comprises an optical fiber male head and an optical fiber female head. An optical fiber insertion core of the optical fiber male head comprises a male head lens seat and a male head insertion core installation seat provided with a male head optical core channel, wherein the male head lens seat and the male head insertion core installation seat are arranged in a split manner. The male head lens seat is provided with a male head lens which is located at a front side of the corresponding male head optical core channel, and a front end part of the male head optical core channel is located at a focus position of the male lens. A female head optical fiber insertion core comprises a female head lens seat and a female head insertion core installation seat provided with a female head optical core channel. The female head lens seat is provided with a female head lens which is located at the front side of the corresponding female head optical core channel, and the front end part of the female head optical core channel is located at the focus position of the female head lens. One of the male head lens and the female head lens serves as a beam-expanding lens which is used for the beam expansion of a corresponding optical signal, and the other one of the male head lens and the female head lens serves as a beam bunching lens which is used for the beam bunching of the optical signal after beam expansion. The assembly provided by the invention can reduce the optical density of a unit area.

The invention relates to a device for trimming the thickness of a mechanical body. Wherein, the trimming is realized in the following manner: a screw is screwed through the threaded hole, one end of the screw presses the center of the disc-shaped part, and the disc-shaped part is deformed to act as a lever to act on the adjacent body. This will reduce the influence of the screw lead on the transmission determined by this lever.

The invention discloses a generation grouped cross-random linear network coding method which comprises the following steps of: sequentially differentiating the generations of original data by an information source, sequentially grouping in each generation and forming a generation set by a generation and the next generation; coding in each generation set, wherein the coding process of each generation sets is independent, and confirming the information package structures of the generation sets by the information source; confirming local sparse coding coefficient vectors according to the number of coding-participating information packages by a node, then, generating a new coding package according to the local sparse coding coefficient vectors and the coding-participating information packagesand sending the new coding package to downstream nodes; carrying out the linear correlation detection of the received new coding package by a node, using the new coding package for coding or decodingif the new coding package passes the detection or else discarding or retransmitting; and adopting a Gaussian column principal component elimination method to decode the original data by a destinationoption node after receiving enough coding packages passing the linear correlation detection. The invention has the advantages of lowering the network coding time and the space complexity and weakening the necessary conditions for correct coding, thereby being suitable for information transmission in information sharing.
