Abstract: This disclosure discloses a media content favoriting method and apparatus, electronic device, and computer-readable storage medium, relating to the field of media content display interaction. The media content favoriting method includes: playing first media content by a playing control in an interactive interface; displaying a media content favoriting control which comprises a first input area and a media information display area of second media content, the second media content corresponding to a first segment between a first time point of the first media content and a second time point of the first media content, and a duration of the first segment being less than a duration of the first media content; and performing a favoriting operation on the second media content in response to detecting an input signal from the first input area.

Abstract: A support interaction method and an electronic device are provided. The method comprises: displaying a playing interface of a video program in an application program; after a first object in the video program appears in the playing interface, displaying a first component, wherein the first component is used for supporting the first object within a first time period, and the first time period is a time period within which the first object played on the playing interface appears in the video program; within the first time period, receiving a first operation executed by a user on the first component; and in response to receiving the first operation, displaying, in the first component, the number of supports from the user for the first object.

Abstract: Embodiments of the present disclosed provides an interaction method and device, a storage medium, and a computer program product, including displaying an input control during a process of playing a first media content through a playback control in an interaction interface; obtaining input information of a current user from the input control; displaying the input information and associated information of the input information; and judging whether the input information and the associated information meet a preset condition, and displaying a second media content based on a result of the judging.

Abstract: The present invention provides a ballast water treatment system, comprising a centrifugal separator, an ultrasonic sterilizer, and an ultraviolet sterilizer, wherein, the centrifugal separator is designed to separate large-particle of foreign matters from the ballast water by centrifugal separation by means of density difference; the ultrasonic sterilizer is arranged at the back of the centrifugal separator, and is designed to accomplish ultrasonic sterilization for the ballast water passing through the centrifugal separator; the ultrasonic sterilizer comprises a pipe that is used for sterilization of the ballast water and ultrasonic irradiation unit that perform ultrasonic irradiation for the ballast water passing through the pipe; the ultraviolet sterilizer accomplishes sterilization by means of ultraviolet irradiation for the ballast water passing through the ultrasonic sterilizer.
