Abstract: A cam-driven wire mesh-type electrospinning apparatus and a use method therefor are provided. The cam-driven wire mesh-type electrospinning apparatus includes the following components: a high-voltage (HV) power supply unit, a wire mesh-type spinneret, a fiber receiving device, a cam unit, and a solution supply unit. The positions and connection relationships of all the components are as follows: any end of the wire mesh-type spinneret is connected to the HV power supply unit, and the other end of the wire mesh-type spinneret is connected to the cam unit; the wire mesh-type spinneret is installed on the solution supply unit; and the fiber receiving device is positioned right above the wire mesh-type spinneret. The cam-driven wire mesh-type electrospinning apparatus may induce a solution to be uniformly distributed on a wire mesh plane, and adjust the density of jet flow and the distribution position of the jet flow.

Abstract: A method and apparatus for processing data in a flash memory are disclosed. The flash memory has a plurality of data blocks for storing data. The method comprises obtaining read modes of read operations which are performed on a data block and a number of each of the read modes, wherein the read modes comprises a sequence read mode and a random read mode, determining a read disturbance value of the data block based on the read modes and the number of each of the read modes, and performing a data move operation for the data block when the read disturbance value of the data block is above a threshold.

Abstract: A sign-in method and server based on facial recognition are provided. The method includes: receiving a face image of a sign-in user from a sign-in terminal. According to the face image of the sign-in user, whether a target registration user matching the sign-in user exists in a pre-stored registration set is detected. The registration set includes a face image of at least one registration user. Further, the target registration user is confirmed as signed in successfully if the target registration user exists in the registration set.
