Embodiments of the present disclosure relate to a method and apparatus for outputting information. The method can include: searching, in response to that user's behavior is preset repetitive behavior being detected, first guidance information matching the user's behavior in a preset guidance information set, where guidance information is used to guide a user to use speech instead of the preset repetitive behavior; and outputting the first guidance information.

Method and apparatus for outputting information

A laser cleaning system including a laser source, an energy-transferring optical fiber, a laser cleaning head, a coreless motor, a connection lens barrel, and a mirror.

Laser cleaning system

Provided are a video pushing method, an apparatus, a device, and a storage medium. In an embodiment of the present disclosure, the number of times a user page is displayed on a user terminal is obtained; if the number of times is less than a preset value, a target video to be pushed to the user terminal is determined according to a popularity of a video in a storage system corresponding to a server; if the number of times is greater than a preset value, a target video to be pushed to the user terminal is determined according to feature information of a user and feature information of a video in the storage system corresponding to the server. Accordingly, the server can continuously push videos that meet the user's needs to the user terminal while the user is using the user page, thereby improving the user experience.

Video pushing method, apparatus, device and storage medium

Embodiments of the present disclosure provides a method for pushing video information, an apparatus, a device and a storage medium. In the embodiments of the present disclosure, the user behavior information in the user page at the current moment is acquired, and the related information of the target video that is pushed to the user terminal at the next moment is determined according to the user behavior information, so that the user terminal refreshes the user page according to the related information of the target video, thus the target video that is pushed by the server to the user terminal is more in line with the user's preference, therefore the user quickly finds the video that he/she likes in the user interface, thereby improving the user experience.

Method for pushing video information, apparatus, device and storage medium

A voice interaction method, device, and terminal. The method includes receiving a wake-up prompt, activating an interactive mode according to the wake-up prompt, displaying a dialog prompt identification in the interactive mode, obtaining a vocal request, wherein the vocal request is input in response to the dialog prompt identification, and displaying a requested content according to the vocal request. In a variety of interaction scenarios, such as in a scenario of interacting with a smart home appliance, a user can continuously provide vocal requests in an interactive mode, without waking up the interactive mode repeatedly, thereby improving user experience.

The present invention relates to a dual-arm clamping type holder for transmission electron microscopy grids and preparation method thereof. The preparation method comprises: firstly manufacturing a frame with two adjacent arms located on a same plane and have a clamping structure by a hard material; then putting the frame in a molten adhering liquid so that the frame is dipped with the adhering liquid; and finally, taking out the frame dipped with the adhering liquid, and waiting for the adhering liquid to solidify into adhering layers along the arms. The dual-arm clamping type holder manufactured by the method of the present invention comprises a frame and adhering layers; and the adhering layers adhere to the inner sides of the clamping structure between the two adjacent arms of the frame.

The present invention relates to a magnetic holder for immunoelectron microscopy grids. The holder comprises a frame, a magnet and a hydrophobic layer. The device can use a magnetic force to simultaneously attach the outer rings of nickel grids to the frame, so that a batch operation (such as rinsing, immunolabeling and dyeing) of the nickel grids can be realized. In addition, due to the hydrophobic effect of the hydrophobic layer, the holder can reduce the amount of the liquid carried by the nickel grids in the process of continuously transferring the nickel grids between different types of liquids to almost zero. Compared with the prior art, the magnetic holder effectively reduces the probability of cross-contamination between reagents.
