Embodiments of this application provide an electronic device, a rotating shaft, a laminated composite material, and a method for manufacturing a laminated composite material. The laminated composite material includes at least two material layers that form the laminated composite material, and the at least two material layers include a first material layer and a second material layer adjacent to each other. The first material layer uses a first metal material, yield strength of the first metal material is greater than 200 Mpa, and an elongation rate of the first metal material is greater than 6%. The second material layer uses a first composite material, and the first composite material includes a second metal material and diamond particles. In this way, heat conduction performance and heat dissipation performance of the rotating shaft are improved while fracture-resistant performance and wear-resistant performance of the rotating shaft are ensured, thereby improving user experience.

In a data flow processing method, multiple data flow queues are obtained. Each of the multiple data flow queues includes one or more data flow sub-queues. A priority of each of the one or more data flow sub-queues is determined. The multiple data flow queues are integrated to a target data flow queue according to the priority. The target data flow queue is sent to a target switch. The method integrates data flows as far as possible and improves the efficiency of data flow scheduling.

Data flow processing method, electronic device, and storage medium

A terminal is provided, and the terminal includes a housing, a front screen, a circuit board, and a power supply. The front screen is disposed on the housing, both the circuit board and the power supply are disposed inside the housing, and the power supply is connected to the circuit board. The front screen includes a toughened glass, a color changing layer, and a display screen that are sequentially stacked. The color changing layer is connected to the circuit board, and can change a color when receiving power supply. The color changing layer is disposed in the front screen, and may change a color when receiving the power supply from the circuit board. The color changing layer is configured to change only a color and cannot display a complex image, and power consumption of the color changing layer is far less than that of the display screen.

A card tray for holding a card in a mobile terminal, a method for preparing the card tray, and a mobile terminal are disclosed. The card tray includes a card tray base, a first insulation layer disposed on the card tray base, and a second insulation layer covering the first insulation layer. Hardness of the first insulation layer is higher than hardness of the second insulation layer. When inserting a card to a mobile terminal, burrs or sharp parts on the card may pierce the second insulation layer, whereas the first insulation layer can block the burrs or the sharp parts, preventing an insulation coating on the card tray base from being scratched.
