Abstract: Embodiments of this disclosure disclose a resource transfer data management method and apparatus, and a storage medium, which belong to the field of Internet technologies. The method includes: receiving transaction data transmitted by a first server, wherein the transaction data is obtained by the first server by signing resource transfer data according to a private key of the first server; verifying the transaction data according to a public key of the first server; and generating a second block according to the transaction data and a feature value of a first block in a blockchain when the verification succeeds, and adding the second block as a next block of the first block to the blockchain.

Abstract: A device is for surface strengthening of a metal plate based ultrasonic vibration is provided. The device includes an ultrasonic vibration tool holder and a cutting tool. The ultrasonic vibration tool holder is internally provided with an ultrasonic transducer and an ultrasonic booster; the ultrasonic transducer is configured to transmit vibration to the ultrasonic booster, the ultrasonic booster is configured to drive longitudinal torsion vibration of the cutting tool; an end of the ultrasonic booster facing towards the cutting tool is provided with an adjustment assembly configured for adjusting a longitudinal torsion angle and a rotation speed. Since the device includes the adjustment assembly, the longitudinal torsion angle and the rotation speed of the device can be adjusted according to different processing requirements, so as to perform ultrasonic vibration extrusion strengthening on surfaces of titanium alloy plates and improve surface integrity including microhardness and residual stress.

Abstract: Embodiments of this application relate to the field of image processing and display technologies, and provide a method for image processing based on vertical synchronization signals and an electronic device, to shorten a response latency of the electronic device and improve fluency (such as a touch latency) of the electronic device. A specific solution includes: drawing, by the electronic device, one or more first layers in response to a first vertical synchronization signal, and rendering the one or more first layers, and after rendering the one or more first layers, performing layer composing on the rendered one or more first layers to obtain a first image frame; and refreshing and displaying the first image frame in response to a second vertical synchronization signal.
