The invention provides an efficient set-retarding and water-reducing agent for cement concrete and a preparation method of the efficient set-retarding and water-reducing agent. The efficient set-retarding and water-reducing agent comprises the following components in parts by weight: 30 to 50 parts of polycarboxylic acid mother liquid, 3 to 5 parts of poly-aluminum chloride, 0.5 to 2 parts of sodium polyaspartate, 10 to 30 parts of allyl polyoxyethylene ether, 0.5 to 0.8 part of coco fatty acid diethanol amide, 5 to 10 parts of hydrogen peroxide, 0.5 to 1.2 parts of mirabilite, 3 to 10 parts of an air entraining agent, 15 to 30 parts of hydrophilic colloid, 1 to 3 parts of a set retarder, 5 to 10 parts of fiber, 1 to 5 parts of asbestos wool, 0.1 to 0.2 part of an initiator and 30 to 50 parts of deionized water. The efficient set-retarding and water-reducing agent is prepared by optimizing the components of the set-retarding and water-reducing agent, modifying part of the components and mixing, so that the efficient set-retarding and water-reducing agent has high compatibility with cement, is small in mixing amount and high in water-reducing rate, can enhance the compression resistance and the fracture resistance of concrete, has a good set-retarding effect, long concrete setting time, high strength and high construction performance, saves construction materials, can save waterand electricity and has high practical value.

The invention discloses a method for achieving the consistency of message forwarding paths. The method comprises the steps that: if network equipment receives a message through a port which enables paths to be unified, a binding record is carried out on a hash calculation result obtained after the element information of the message is subjected to hash calculation and the port number of the port for receiving the message; if a message which is the same as the hash calculating result is received through the port which cannot enable the path to be unified, the message can be forwarded based on the binding record. On the basis of the same inventive concept, the invention also provides network equipment which can conveniently and flexibly achieve the consistency of the paths during forwarding the message and the capacity expansion of the network is not influenced.

The invention relates to the technical field of fireproof doors and windows, and discloses a steel energy-saving fireproof window and a manufacturing process of the steel energy-saving fireproof window. The fireproof window comprises an outer frame and an inner fan. The inner fan is provided with double-layer glass. A push-and-pull assembly is arranged between the inner fan and the outer frame andcomprises a hinge with a torsion spring. A first connecting plate is hinged to the top of the inner fan. A first hinging shaft is rotationally connected to the other end of the first connecting plate. A sliding piece is slidably connected to the top of the outer frame. A second hinging shaft is fixed to the bottom of the sliding piece. A second connecting plate is hinged to the second hinging shaft. A strip-shaped groove allowing the first hinging shaft to slide is formed in the second connecting plate. One end of the sliding piece is bent downwards and fixedly provided with a memory metal sheet and an expansion block. One end of the memory metal sheet is bent upwards and is clamped with clamping grooves, wherein the clamping grooves are distributed in the top of the outer frame. When heat is introduced to the expansion block, the end portion of the memory metal sheet is pushed out from the clamping grooves, the torsion spring drives the inner fan to rotate towards the outer frame until the fireproof window is closed, so that an automatic closing function is achieved, and the inhabitation of fire diffusion is facilitated.

The application provides a rake tooth type biomass material conveying device, including: a first traction chain, a second traction chain, a rake tooth, a drive shaft, a transmission shaft, an intermediate partition, a lower bottom plate, a feeding port and a spiral tensioning device; the driving shaft and the transmission shaft are arranged symmetrically; the helical tensioning device is connected with the driving shaft to control the tension of the first traction chain and / or the second traction chain; the The first traction chain is respectively engaged with the drive shaft and the transmission shaft; the second traction chain is arranged symmetrically with the first traction chain, and the second traction chain is respectively connected with the drive shaft and the transmission shaft. The transmission shaft is meshed; so that the drive shaft drives the first traction chain and the second traction chain to perform chain transmission around the transmission shaft. The application solves the problems that the belt conveyor occupies a large area and consumes a lot of manpower and material resources; and the belt conveyor has poor conveying capacity and low efficiency during construction.

To provide an air bag module cover structure suited to use for a motorcycle, by enhancing toughness and the like. Tear lines as brittle portions are provided not in the surface of a module cover (22) liable to influences of external factors such as rain, dust, etc. but at upper portions of three side surfaces other than the side surface facing to the vehicle front side, of four side surfaces of a roughly rectangular parallelopiped-shaped air bag module (20). Three tear lines are provided; specifically, both side surfaces facing in the vehicle width direction are each provided with a first tear line (26) at portion B shown in the figure, and a second tear line (27) is provided in portion C shown in the figure other than portions D shown in the figure as slits (4) for passing air bag support belts therethrough. Therefore, at the time of inflation and development of the air bag, the module cover (22) is developed in such a manner as to open a lid, with one side on the vehicle front side of a casing (23) as an axis. Besides, at one side on the vehicle front side, stoppers are formed to make it difficult for the module cover (22) to be opened beyond a predetermined angle.

The disclosure provides a webpage rendering method and device, electronic equipment, and a computer-readable storage medium. The disclosure is designed in the field of big data technology and can be used in the field of financial technology. The method includes: receiving an access request from a client for a target webpage; in response to the access request, judging whether there is static resource data related to the target webpage in a local cache of the data processing service cluster; and whether there is no static resource data in the local cache In this case, obtain static resource data from the shared storage server and cache the static resource data locally in the processing service cluster; obtain dynamic resource data related to the target web page from the business server; process the static resource data and dynamic resource data Then return to the client, so that the client can perform webpage rendering operations related to the target webpage according to the processed static resource data and dynamic resource data.
