A system and method for automatically restoring a network containing failed converter nodes. A protection ring is generated for network restoration, and a ring group is generated from the protection ring. Each node is equipped with a protection switch (105) internally interconnecting the input / output to the connection link through the interconnecting protection fiber. The selection of which inner protection fiber to switch traffic on allows configuration of nodes to create merged ring groups. In this way, if a failure of the central converter is detected, the transmission information is diverted to the selected protection fiber of the corresponding merged ring group, so that the information can automatically pass through the protection fiber bypassing the faulty node. Each protection switch has associated with it mapping data that defines which protection fiber should be switched to in terms of input and output links for transmissions that need to be sent through the node. The system and method are applicable to both non-planar and planar networks.

The invention relates to Bi-planar network architecture. An electronic communication network adopting Bi-planar network architecture includes a connectivity plane and a control plane. The control plane includes at least one control node for inspecting packets received by the control plane. The control plane is configured to perform network traffic control functions on the packets received by the at least one control node before transmitting the packets to any other node in the network. The network traffic control functions include one or more of access control, attack control, and application control.

The invention discloses a manufacturing method of a sheet material and a three-dimensional structure made thereof. The sheet comprises wide ribs, repeated longitudinal narrow ribs and repeated transverse ribs, and the repeated transverse ribs include the entire ribs running through the transverse direction of the sheet or the part of the edge of the sheet Ribs. The manufacturing method of the sheet is to heat and stretch an orifice plate with a specific hole spacing; or to directly punch or cut holes on the plate. Through the connection between the sheets and the narrow ribs in the sheets, they are grouped, and after unfolding, a three-dimensional structure including a honeycomb facade structure and a planar network structure is formed. The invention has dual functions of preventing local settlement of the soil body and sideways movement of the soil body, and is an ideal reinforcement material for civil engineering.

The support (3) has an opening (5) therein, at the peripheral region (4) of which opening (5) the network (2) is in contact with the support (3), such that the middle part of the network (2) is unsupported by the support (3). The network (2) comprises essentially randomly oriented HARM-structures.

The invention discloses a high-temperature resistant fiber layer composite filter material and a method for preparing the same. The cross section of the material adopts a triple-layer structure, the upper layer and the lower layer are both a mixed fiber layer, and the middle layer is the PTFE base fabric layer. The preparation comprises the following steps of: preparing PPS fibers and PTFE fibersfor later use; mixing two kinds of raw materials in a cotton-mixing box to obtain a preliminary mixed material; loosening the preliminary mixed material in a loosening machine; performing refined mixing of the loosened material in the cotton-mixing box; carding the refined mixing material into planar network fibers by a carding machine; spreading the planar network fibers by a lapping machine to make the mixed fiber layers; adding the PTFE base fabric layer between the two mixed fiber layers; preparing the composite fiber material by a needling machine; and putting the composite fiber material in shaping equipment for shaping, putting the composite fiber material in coating equipment for coating, and then performing surface singeing treatment to obtain the filter material. The filter material of the invention possesses high thermal stability, chemical stability, corrosion resistance and electrical property, and compared with the conventional materials, the oxidation resistance and thecorrosion resistance of the filter material are greatly improved.

The invention discloses a solar cell production process using net-knot-free printing and relates to the technical field of solar cell production. An anode is printed by a net-knot-free printing manner. The solar cell production process specifically includes the steps of firstly, preparing silver paste, to be more specific, stirring, by weight percentage, 70-75% of silver powder, 10-15% of graphene powder, 2-4% of glass powder and 12-15% of organic carrier in a stirring device at 85 DEG C for 10-12 hours; secondly, producing a screen, to be more specific, using a planar network structure integrally formed by 3D printing, and reserving printing down alignment space at positions needing line printing to obtain the printing screen; thirdly, printing, to be more specific, placing the printing screen obtained in the second step on a moving mechanism which parallelly moves relative to a printing bearing table, allowing a plane where the screen is located to be parallel with a plane where the printing bearing table is located, and printing with the silver paste obtained in the first step. The solar cell production process has the advantages that the production process is good in printing effect, and the problems that the printing paste is severely affected by net knots formed warps and wefts on screen cloth, and defects such as printing line breaking are caused in the prior art are solved.

The invention provides a surgical organ isolation pad, which includes an isolation pad body made of a polymer elastomer, and is characterized in that: a sheet metal mesh is arranged in the middle of the isolation pad body as a skeleton, and the material of the sheet metal mesh is Medical stainless steel, cobalt-based alloys, nickel-titanium alloys, tantalum, niobium or zirconium metals. The thickness of the sheet metal mesh is 0.2mm‑2mm; the structure of the sheet metal mesh is a woven mesh or a molded mesh formed on a plane, the edge of the sheet metal mesh is smooth, and the mesh shape of the sheet metal mesh is square, rectangular, Circle, oval, triangle or hexagon. The shape of the isolation pad can be changed by hand according to the needs, and the abdominal organs can be effectively isolated or retracted after being placed at the desired position in the abdominal cavity, without the use of metal retractors to fix and protect the organ tissue; the isolation pad can be tracked under X-ray, eliminating the need hidden dangers in the body. Moreover, it is easy to use and greatly shortens the preparation time for surgery.
