The utility model discloses a ball disc and game machine for game equipment technical field. The ball disc is provided with a ball inlet groove and a ball falling groove. The ball inlet groove extends along its length direction. One end of the ball inlet groove penetrates the disc wall of the ball disc to form a ball inlet on the disc wall of the ball disc for the ball to enter. The other end of the ball inlet groove penetrates the groove wall of the ball falling groove. The inner bottom surface height of the ball inlet groove is greater than or equal to the inner bottom surface height of the ball falling groove. The ball falling groove is provided with a ball falling through hole for the ball to fall. The inner circumferential surface of the ball falling groove is an annular inclined surface around the ball falling through hole. The width of the ball inlet groove matches the outer diameter of the ball. The width and length of the ball falling groove are greater than the width of the ball inlet groove. The length direction axis of the ball inlet groove is different from the axis of the ball falling through hole. The ball that leaves the ball inlet groove rolls in the circumferential direction in the ball falling groove. After the ball falls into the ball falling groove, it cannot directly fall into the ball falling through hole and needs to roll in the circumferential direction on the annular inclined surface of the ball falling groove. The ball stays on the ball disc for a long time.

The application provides a high-speed random number generator based on a conservative chaotic system and a generation method thereof. The generated random number is subjected to two commonly used random number test standards, namely, a test suite NIST SP800-22 of The National Institute of Standards and Technology and another test suite TestU01, and experimental test results can prove that the generated random bit sequence passes the randomness test. The throughput of the high-speed random number generator can reach 19 Gbps.

This disclosure provides a virtual object control method, comprising: displaying a game scene of a game match on a graphical user interface of a terminal device, the game scene including a first virtual object corresponding to the terminal device and a second virtual object belonging to a different faction from the first virtual character; determining a second buff effect in response to the first virtual object performing a first defeat operation on the second virtual object, wherein the second buff effect belongs to a second type of buff effect; applying the second buff effect to the first virtual object; updating the continuous defeat state of the first virtual object; determining a first buff effect corresponding to the updated continuous defeat state based on the updated continuous defeat state, wherein the first buff effect belongs to a first type of buff effect; and applying the first buff effect to the first virtual object. This allows players to obtain dynamic buff effects through defeat operations during game matches, achieving a "fight and grow" gaming experience.

This invention relates to the field of tea processing technology and discloses an automatic spreading fermentation device for tea processing, including a base. A fermentation box is fixedly connected to the top of the base. A fermentation frame is set inside the fermentation box, and several round holes are opened inside the fermentation frame. By driving a sliding sleeve to move laterally back and forth along the sliding rod through an electric push rod, a turning rod is driven to move a long distance within the fermentation frame, improving the uniformity of tea turning. During the translation process, the gears at both ends of the rotating rod mesh with the rack. When it moves to the rack sections at the left and right ends of the box, the gears drive the rotating rod and the turning rod to rotate automatically, changing the material-pushing angle of the turning rod from translational pushing to rotational turning and throwing. This forces the bottom layer of tea leaves to rise and the surface layer of tea leaves to sink, achieving deep three-dimensional replacement, significantly improving the uniformity of fermentation, and completely solving the problems of dead material accumulation at the end, local over-fermentation, or mold growth that exist in traditional scraper-type turning. This ensures that every piece of tea leaves participates in the cyclic turning process.

This invention discloses a method and system for encrypted storage of power data, applied in the field of power system information security technology. The method includes: acquiring power data to be encrypted from a target power system; determining a dynamic time-series characteristic sequence based on historical operating status data of the target power system; grouping the power data to be encrypted into individual data groups; determining a session key for each data group based on the analysis results of the historical operating status data; encrypting each corresponding data group using each session key to obtain ciphertext data; encrypting all session keys using the master key in an asymmetric encryption algorithm to obtain encrypted session keys; associating and encapsulating all ciphertext data and encrypted session keys, and storing the association and encapsulation result in a secure database. This invention achieves secure and stable encrypted storage of power data.
