This invention discloses a zirconium-lanthanum bulk co-doped high-nickel ternary material, its preparation method, and a battery. The zirconium-lanthanum bulk co-doped high-nickel ternary material is a ternary cathode material with bulk co-doped zirconium and lanthanum; the chemical formula of the ternary cathode material is LiNi. x Co y Mn (1‑x‑y) O2, wherein 0.8≤x≤0.9, 0≤y≤0.1; the total molar amount of zirconium and lanthanum is 1%~5% of the total molar amount of nickel, cobalt and manganese. The zirconium-lanthanum bulk co-doped high-nickel ternary material provided by the present invention enhances the mechanical strength of the ternary material through the bulk co-doping of zirconium and lanthanum, suppresses cracking and pulverization of the ternary material during charge and discharge, and improves cycle stability; at the same time, the two elements Zr and La synergistically stabilize the lattice, reduce lithium-nickel mixing, suppress irreversible phase transformation and lattice oxygen precipitation, achieve dual stability of bulk phase and interface, and improve the consistency and stability of the zirconium-lanthanum bulk co-doped high-nickel ternary material.

This utility model discloses a light-emitting component and a lamp, including a reflector cup and a biconvex lens. A reflective surface is provided on the inner side of the reflector cup, forming a reflective channel. One end of the reflective channel has a light inlet, and the other end has a light outlet. The biconvex lens is disposed on the reflector cup and covers the light outlet. The biconvex lens has an inner protrusion and an outer protrusion. The inner protrusion faces the reflective channel, and the outer protrusion faces away from the reflective channel. The light-emitting component uses a reflector cup and a biconvex lens. When in use, the biconvex lens can also narrow the range of the secondary light spot, resulting in a more uniform transition between the main and secondary light spots, a clear and rounded outer edge of the light spot, and good overall brightness. Furthermore, the inner protrusion of the biconvex lens faces into the reflective channel, while the outer protrusion faces away from the reflective channel, reducing the outward convexity of the biconvex lens relative to the reflector cup. This makes the structure of the light-emitting component more compact and improves its versatility in assembly.

This invention discloses a heat treatment method for train wheels, comprising the steps of: S1, heating the wheel; S2, water-quenching the wheel; and S3, tempering the wheel. In step S2, a composite nozzle is used, with a first nozzle region, a second nozzle region, and a third nozzle region sequentially arranged on the composite nozzle. The first nozzle region is equipped with a first nozzle for spraying air onto the wheel tread surface, the second nozzle region is equipped with a second nozzle for spraying water mist onto the wheel tread surface, and the third nozzle region is equipped with a third nozzle for spraying cooling water onto the wheel tread surface. This heat treatment method for train wheels utilizes a composite nozzle during quenching to reduce the near-surface cooling rate of the wheel tread surface. By employing compressed air and appropriately adjusting the flow rate of cooling water (small / large flow), the rapid cooling of the near-surface layer of the rim is reduced, effectively increasing the cooling rate of the internal matrix. This results in a more uniform microstructure in the radial direction of the wheel rim, achieving a uniform transformation of the internal microstructure and reducing the hardness gradient.

Through the technical scheme, the problems of the existing technology, such as the difficulty in treating the flaws of the yarn, the complicated operation, the waste of time and the inconvenience in controlling the temperature of the glue liquid, are solved.

This invention relates to the field of beauty and hairdressing technology, specifically to a hair dyeing method for hair styling. This invention employs a precise application process, dividing the hair into sections and applying the dye to the ends first, followed by the roots, while controlling the oxidation reaction time and temperature. Finally, a special conditioner is used for color-locking treatment. This method effectively covers gray hair and produces a uniform and natural color after dyeing. The dyeing process is safe, comfortable, and non-irritating. Furthermore, this invention combines dyeing, immediate repair, and long-lasting color fixation, achieving an integrated approach from operation to effect, significantly improving the overall quality of hair styling and the user experience.
