Abstract: Embodiments of this application relate to the field of storage technologies, and disclose a data backup method and a terminal, to back up user data in a terminal when the terminal cannot be used. A specific solution is as follows: A terminal includes a first data partition, and the first data partition supports to start an operating system when the terminal is powered on. The terminal starts the operating system by using a second data partition after detecting a power-on failure of the terminal or detecting a preset operation of a user. The second data partition is a blank data partition. After the operating system is successfully started, the terminal transmits user data in the first data partition to a first storage medium. The first storage medium is located outside the terminal and is connected to the terminal.

Abstract: Disclosed is a pollen control dry pollination machine for Abies ziyuanensis, comprising a lever; a side of a top of the lever is fixedly connected with one end of a square tube; another end of the square tube is rotatably connected with a pollination shell; a top of the square tube and a top of the pollination shell are slidably connected with a fan; the pollination shell is internally provided with a pollen box, a pollen outlet cover and a pollination chamber from a top to a bottom in sequence; the pollen box is communicated with the pollen outlet cover; a bottom of the pollination chamber is provided with an opening; an Abies ziyuanensis ovulate strobilus to be pollinated is placed in the pollination chamber; a bottom of the pollination shell is fixedly connected with a rotating opening; the lever is provided with a switch.

Abstract: The present invention provides a graded braking control device and control method for vehicle tire burst, and belongs to the technical field of vehicles. It solves the problems of rear-end collision and more instability of the vehicle resulting from emergency brake after vehicle tire burst. The device includes a tire pressure sensor, a controller, a radar sensor, a stability detection module and an ESC, wherein the radar sensor and the stability detection module are respectively connected with input ends of the controller, the tire pressure sensor is in wireless connection with the controller, and the ESC is connected with an output end of the controller. The control method includes: 1. monitoring vehicle tire condition; 2. carrying out traffic state assessment and determining a first maximum braking deceleration value for preventing the rear-end collision with the follower vehicle after emergency brake of the present vehicle; 3.
