This invention relates to a nickel-plated steel sheet with excellent corrosion resistance for battery casings and a method for manufacturing the same. In one specific embodiment, the nickel-plated steel sheet comprises: a base steel sheet; a nickel plating layer formed on at least one surface of the base steel sheet; and a nickel-iron diffusion layer formed between the base steel sheet and the nickel plating layer. The nickel plating layer and the nickel-iron (Ni-Fe) diffusion layer are formed by heat treatment after forming an electroplated nickel layer on the base steel sheet and a chemically plated nickel layer on at least a portion of the surface of the electroplated nickel layer. The nickel plating layer contains one or more vacancy elements selected from phosphorus (P), boron (B), tungsten (W), cobalt (Co), molybdenum (Mo), and copper (Cu) on its surface.

The embodiment of the utility model discloses a rotor structure and a motor. The rotor structure comprises a rotor core and a sheath layer. The sheath layer is wound on the rotor core and wraps the outer circumferential surface of the rotor core in the circumferential direction, the sheath layer is arranged in a segmented mode in the axial direction, and a sheath gap is formed between the side edge of a single segment of the sheath layer or between every two adjacent segments of the sheath layer; wherein the sheath layer is made of a fiber material. According to the rotor structure, the section-shaped annular sheath structure is formed by wrapping the sheath layer, and tension control is applied to the fiber material in the wrapping process, so that pressure stress is formed on the surface of the rotor iron core after the annular sheath structure is formed, and the rotor iron core has certain prestress, so that the iron core has the capability of resisting larger centrifugal force; the maximum working speed of the rotor is improved. Besides, compared with a sleeve-shaped structure, the sheath layer arranged in a segment shape can ensure that pressure stress is formed on the surface of the rotor iron core, and can save production cost at the same time.

This invention provides a road petroleum asphalt-based hard-soft carbon composite material, the raw materials of which include road petroleum asphalt, light component small molecule stabilizer, heavy component small molecule oxidant, activator, and solvent; and the ratio of road petroleum asphalt:solvent:light component small molecule stabilizer:heavy component small molecule oxidant:activator is 1:15-25:0.05-0.2:0.05-0.2:2-5, calculated in g / mL / g / g / g. Furthermore, this invention also provides a method for preparing the aforementioned hard-soft carbon composite material, which includes the following steps: crosslinking treatment of the light component, crosslinking treatment of the heavy component, activation, and carbonization. This invention solves the problem in the prior art where the high price or low carbon yield of hard carbon precursors, high cost of oxidants, or complex overall formulations lead to high costs for the prepared asphalt-based sodium-ion battery anode carbon materials. The hard-soft carbon composite material of this invention not only has a lower cost but also combines the advantages of both hard and soft carbon, exhibiting high sodium storage capacity, high reversible specific capacity, high initial charge-discharge efficiency, and good cycle performance.

This invention discloses a shaped bottle filling production system, including a base, a conveying mechanism mounted on the base, and a front weighing station, a filling station, a rear weighing station, and a capping station arranged sequentially along the conveying direction of the conveying mechanism. The conveying mechanism has multiple bottle holders arranged at intervals along the conveying mechanism, each bottle holder for holding a group of shaped bottles. The base also has a weighing device, and a transfer device connects the weighing station and the weighing device. The conveying mechanism conveys intermittently for a predetermined time, advancing the distance of one bottle holder each time. A shaped bottle filling production method is also disclosed, using the shaped bottle filling production system, including the following steps: bottle placement; front weighing; filling; rear weighing; and capping. This shaped bottle filling production device and method has advantages such as short total downtime, high working efficiency, and low production cost.

This invention discloses a structural variation molecular marker on chromosome 5 of pigs that affects the weight of subcutaneous abdominal fat and its application. The structural variation molecular marker is a DNA fragment inserted after the 66120412 bp site on chromosome 5 corresponding to the International Pig Reference Genome Version 11.1; the nucleotide sequence of the DNA fragment is shown in SEQ ID NO:1. The structural variation molecular marker provided by this invention is significantly correlated with the trait of subcutaneous abdominal fat weight in pigs. By identifying this structural variation molecular marker, the trait of subcutaneous abdominal fat weight in pigs can be identified. Furthermore, by selecting individuals carrying the structural variation molecular marker during the breeding process, the subcutaneous abdominal fat weight of offspring pigs can be reduced, and the lean meat percentage of offspring pigs can be increased.
