Abstract: The embodiment of the disclosure provides a content transmission method and apparatus, a device and a storage medium. The method includes: in response to receiving a first request for content from a client, obtaining a plurality of pieces of content, wherein the first request comprises a user identifier; splitting the plurality of pieces of content into a plurality of groups of content; transmitting a first group of content in the plurality of groups of content to the client; storing other groups of content in the plurality of groups of content; and in response to receiving a second request comprising the user identifier for the content from the client, transmitting a second group of content in the stored other groups of content to the client. Therefore, the efficiency of content transmission is improved.

Abstract: A vibration dampener, including, a first beam comprising a first mounting end portion and a first peripheral end portion, wherein the first peripheral end portion comprises a tunable mass, and the first beam is configured to vibrate in tune with a vibrational frequency of a structure supporting the first beam at the first mounting end portion, a second beam comprising a second mounting end portion and a second peripheral end portion, wherein the second peripheral end portion comprises a ring disposed about the first beam, and a viscoelastic material disposed between the first beam and the ring, wherein the viscoelastic material is configured to dampen vibrational energy as the first beam vibrates toward the ring until the viscoelastic material becomes compressed between the first beam and the ring during the course of the impact.
