Abstract: An inversion method of river course depth based on a mathematical model and remote sensing of water depth-water surface area includes the following steps: constructing the first mathematical model; calculating the relation function between the water flowing cross-section area, the triangle area at two sides and the water depth as well as the flow path, and substituting the relation functions into the first mathematical model to obtain the second mathematical model; transforming the second mathematical model into the mathematical model of water level-water surface area; solving the unknowns in the mathematical model, and substituting the unknowns into the second mathematical model to obtain the third mathematical model; and substituting the water surface area extracted by the remote sensing into the third mathematical model to obtain the water depth of the river course.

Abstract: Disclosed are a passive triggered-power electronic tap-changer device and a contact device. The power electronic tap-changer device comprises: two taps, a main contact, two auxiliary contacts, two trigger contacts, an output terminal, two thyristors, and four voltage divider resistors, which can achieve the passive triggering of a power electronic switch by means of controlling the auxiliary contacts and the trigger contacts. Provided in the present invention is a contact device for the passive triggered-power electronic tap-changer, comprising: at least two stationary contacts, a main contact, two thyristor trigger contacts, two thyristor auxiliary contacts, and a drive shaft, wherein the main contact, the thyristor trigger contacts, and the thyristor auxiliary contacts are fixed to the drive shaft, the contact device can switch the power electronic switch to different stationary contacts by means of controlling the rotation of the drive shaft, and maintains the switching time sequence of passive triggering.

Abstract: Embodiments of the present disclosure provide a method and apparatus for displaying media content, a device, a storage medium, and a program product. The method comprises: determining, in response to a first trigger operation of viewing first media content, whether the first media content satisfies a preset content association condition, wherein the first media content is contained in a media content stream displayed in a media content display interface; and displaying target media content in the media content display interface in response to determining that the first media content satisfies the preset content association condition, and displaying at least two first progress controls in a preset area of the media content display interface, wherein the target media content comprises the first media content and at least one piece of second media content that is content-associated with the first media content.

Abstract: Provided is a video playback method, applicable to an anchor client. The method includes: displaying a video selection interface in response to a video display operation on a target account, wherein the video selection interface includes at least one video posted by the target account; sending a video playback request to a video server in response to a select operation on a target video in the video selection interface, wherein the video server is configured to transmit the target video to a live streaming server in response to the video playback request, and the live streaming server is configured to insert a video frame of the target video into a live streaming frame corresponding to the anchor client and push a live stream; and displaying the live streaming frame with the video frame inserted.
