This invention discloses a four-armed star-shaped polymer containing a polyoxyethylene structure, its preparation method, composition, and applications. The polymer is prepared by mixing an unsaturated organic carboxylic acid compound, an unsaturated sulfonic acid compound, and water, stirring to obtain a reaction solution, and continuously stirring and heating the reaction solution. An aqueous solution of a polyether macromonomer compound and the initiator aqueous solution are added to the heated reaction solution, followed by polymerization and purification. The polymer structure contains a large number of carboxyl groups, sulfonic acid groups, and ether groups, as well as abundant polyoxyethylene groups and alkyl chains, giving the polymer good water solubility and excellent chelating properties for metal ions. The polymer prepared by this method shows good effects in cleaning, defoaming, and scale inhibition. Furthermore, compositions formed by combining the polymer with other corrosion and scale inhibitors exhibit good compatibility and can be used for scale inhibition in high-hardness water.

The utility model relates to the technical field of fixed hydraulic clamps, and discloses a fixed hydraulic clamp for machining, which comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a hydraulic rod, the output end of the hydraulic rod is fixedly provided with a support, and the inner wall of the support is rotatably connected with a connecting block. A bearing plate is fixedly connected to the upper surface of the connecting block, a rotating rod is rotatably connected to the outer wall of the bearing plate, a rotating shaft is rotatably connected to the inner wall of the rotating rod, a sliding block is fixedly connected to the outer wall of the rear side of the rotating shaft, a sleeve is slidably connected to the outer wall of the sliding block, and a clamping block is fixedly connected to the outer wall of the sliding block; and an overturning assembly is arranged on the upper surface of the bottom plate.

This disclosure provides a message transmission method, apparatus, electronic device, related medium, and program product. The message transmission method includes: generating a data packet; wherein a first field in the data packet has a first original port number; determining that a first original path from the sending device to the receiving device is congested based on a congestion window value corresponding to the current routing period of the sending device; selecting a first virtual port number corresponding to the current routing period from a first set of candidate port numbers, updating the first field with the first virtual port number, and placing the first original port number in a second field of the data packet; the first virtual port number is used for routing calculations to obtain a first alternative path from the sending device to the receiving device; and sending the data packet so that after receiving the data packet, the receiving device extracts the first original port number from the second field and updates the first field with the first original port number for transport layer protocol processing. This disclosure can effectively improve message transmission efficiency.
