摘要： Provided are a concrete member reinforcement method and a concrete reinforcement structure. The concrete reinforcement structure includes a concrete member, a first bonding body, a second bonding body, and a fiber-reinforced composite strip. At least one groove is formed on a surface of the concrete member, and a first binder is used for filling the groove to form a first bonding body. A second binder is used for being coated on the surface of the concrete member provided with the groove, as well as the top surface of the first bonding body to form a second bonding body. The fiber-reinforced composite strip is used for being pasted on a surface, far away from the first bonding body, of the second bonding body, so that the fiber-reinforced composites can be firmly combined with the concrete member and are not easy to fall off.

摘要： A multi-stage FPGA routing method for optimizing time division multiplexing comprises the following steps: S1: collecting an FPGA set, an FPGA connection pair set, a net set and a net group set; S2: acquiring a routing topology of each net according to the FPGA set, the FPGA connection pair set, the net set and the net group set under the condition where TRs are not assigned; S3: assigning a corresponding TR to each edge of each net according to different delay of each net group; and S4: performing TR reduction and edge validation cyclically, iteratively optimizing net groups with TR being greater than a preset value until iteration end conditions are met, so as to obtain an optimal routing result. The multi-stage FPGA routing method may optimize the delay of inter-chip signals of a multi-FPGA prototype system and guarantee the routability of the multi-FPGA prototype system.

摘要： The present disclosure relates to a construction method for a deformable anchor cable capable of being prestressed. The anchor cable includes an outer sleeve, a shrinkage pipe, an inner sleeve, a steel strand, an anchor and a tray. When the anchor cable is in use, a hole is drilled first, then the anchor cable is mounted in the drilled hole, and finally a prestress is applied to the steel strand of the anchor cable. According to the construction method, the construction is convenient; the anchor cable has the characteristics of high strength and large deformation, and can be easily prestressed; and the large deformation is realized by squeezing the inner sleeve by means of the anchor, which completely overcomes the problem of breaking a cold-drawn rod during the large deformation process.

The ruthenium-based catalyst comprises Ru—Ba-A core-shell structure which comprises a ruthenium nanoparticle as a core covered with a first shell and a second shell sequentially, wherein the first shell consists of a barium nanoparticle, and the second shell consists of a metal oxide. The Ru—Ba-A core-shell structure can effectively preventing agglomerations of ruthenium nanoparticles during the use of the catalyst and avoiding direct contact between the ruthenium nanoparticles and the metal oxides. In addition, barium nanoparticles have a promoting effect as an electronic promoter, which can effectively improve the stability and catalytic activity of ruthenium-based catalyst for ammonia synthesis, especially in the system for synthesizing ammonia from a coal gas.
