This invention, entitled "A Synergistic Antibacterial Composition and Its Application," belongs to the field of pharmaceutical technology. The technical problem to be solved is to provide a synergistic antibacterial composition and its application, wherein the obtained antibacterial composition has a synergistic inhibitory effect on infection, synergistically inhibiting *Escherichia coli*, *Klebsiella pneumoniae*, carbapenem-resistant *Enterobacter cloacae*, *Pseudomonas aeruginosa*, *Acinetobacter baumannii*, and *Proteus mirabilis*. The key technical points are: the antibacterial composition includes: any one of cefbirol or a cefbirol derivative; and any one of nakubatane or a nakubatane derivative; specifically, according to C... 20 H 22 Based on N8O6S2, the mass ratio of cefbirol or a cefbirol derivative to nakubatane or a nakubatane derivative is 1-4:1-8. The antibacterial composition obtained in this invention is used in the preparation of pharmaceuticals with anti-infection properties.

The application discloses a powder core wire for a gearbox valve body with super high strength and toughness, which comprises a powder core and a sheath. The powder core is composed of the following powders in percentage by mass: carbon powder 0.5%, manganese powder 10%-15%, chromium powder 10%-15%, nickel powder 15-20%, titanium powder 1%, silicon powder 1%, molybdenum powder 2%, copper powder 2%, CeO2 powder 1.5%-2%, and iron powder in the rest. The sheath is a low-carbon steel belt. The filling rate of the powder core wire is 20wt%-25wt%. The powder core wire is used for 3D printing to manufacture a super high strength and toughness structural member. The application also discloses a gearbox valve body with super high strength and toughness, a preparation method of the powder core wire for the gearbox valve body with super high strength and toughness, and a preparation method of the gearbox valve body with super high strength and toughness.
