Abstract: The present disclosure discloses a screen projection method, a screen projection apparatus, an electronic device, and a computer-readable storage medium. The screen projection method includes: sending a search file to search a client, the search file including an equipment identification and configuration parameters of a server, the configuration parameters of the server including parameters for selecting a target client; receiving a search response message returned by the client, the search response message including an equipment identification and equipment parameters of the client; determining the target client meeting a screen projection condition according to the search response message; and sending a screen projection file to the target client.

Abstract: A social processing method includes displaying a session interface of a social session comprising N social objects, N being an integer greater than 1, and each social object having an avatar, the avatar being an image configured for interacting with other social objects through an interaction behavior; obtaining configuration information, the configuration information being information on M avatars to-be-displayed of N avatars, and M being an integer less than or equal to N; and displaying the M avatars in the session interface according to the configuration information.

Abstract: In an image transmission method, a first image is displayed in a messaging interface. The first image includes an interaction effect between a plurality of virtual objects. A request is received from a current user to transmit a second image that is based on the first image. A target user to which the second image is to be transmitted is determined. The second image that is generated according to object information of the determined target user and the first image is displayed in the messaging interface. The second image and the first image include the same interaction effect.

Abstract: The invention relates to a composition containing total triterpenoid sapogenins extracted from bamboo, the preparation method and use thereof. These total triterpenoid sapogenins are extracted from many parts of bamboo such as bamboo shavings in Gramineae by CO2 Supercritical Fluid Extraction technique. In the extract, the content of total triterpenoid sapogenins is 10-90%, while the contents of friedelin and lupenone are 5-35% and 1-10%, respectively. The extract in the invention has good physiological and pharmacological activities such as anti-free radical, anti-oxidation, anti-tumor and anti-hypertension. It can be used in medicines or functional foods for the treatment or prevention of cardiovascular and cerebrovascular diseases and tumor. It is also useful in cosmetics field.

Abstract: An electrical connector (1) mounted on a circuit board is provided for mating with an electric device. The electrical connector includes a dielectric housing (10) having a terminal passage (16), a pair of conductive contact elements (20) received in the housing, and a fixing pad (30) connecting the circuit board. Each conductive contact element includes a base portion (21) positioned in the terminal passage, a tail portion (22) arranged on one side of the housing for connecting with a circuit board, a contacting portion (24) which serves for contacting the electric device, and a spring portion (23) connecting the contacting portion resiliently to the base portion. The fixing pad is fixed to the other side of the housing for providing balanced force acted on the electrical connector during mating with the electric device.
