Abstract: The disclosed embodiments provide a method for interaction, apparatus, electronic device and storage medium. The method comprises: in response to a display operation, displaying a user avatar interface, wherein user avatars of at least two user are displayed in the user avatar interface; determining a target user avatar in the user avatar interface, the target user avatar is one of the user avatars of the at least two users; in response to an interactive operation for the target interface, executing an interactive event of a target user corresponding to the target user avatar, the target interface supporting different types of interactive operations, the different types of interactive operations corresponding to different types of interactive events, and the target interface including the user avatar interface.

Abstract: The embodiments of the disclosure provide a method, an apparatus, an electronic device and a storage medium for publishing a virtual image. The method includes: receiving an avatar creation operation on a preset page, the preset page displaying a target object and a user identifier of at least one associated user of a current user; in response to the avatar creation operation, obtaining a first avatar and a state of a target status identifier corresponding to the first avatar; receiving an avatar publishing operation for the first avatar; and in response to the avatar publishing operation, publishing the first avatar performing a target association action, wherein the target association action is an association action of the state of the target status identifier corresponding to the first avatar.

Abstract: An electric vehicle (EV) user network system (100) having a dedicated server (110) and a cloud server (120) for connecting EV owners and users, EV charging stations and EV charging networks, and EV related businesses, comprising an EV Power Grid of charging stations and charging network (20); a One-Stop Shop connecting all EV related businesses in the network (40); a technical support & services network (70), and an Account for each user (50) connecting the user to the EV Power Grid, One Stop Shop and the technical support & services network; all the users and EV related businesses connected and communicating with each other in a community network for dissemination and education of EVs and EV related matters (60). The EV user through an User Account is connected to the EV Power Grid, the One-Stop Shop (40), EV related businesses, technical support & services network and other users in the network through the community network (60), in real-time.

Abstract: A catalyst for the polymerization of propylene comprising components (A), (B) and (C) is provided. Component (A) is a solid product prepared by dissolving a halide of magnesium in a solvent system consisting of an organic epoxy compound, an organic phosphorus compound and an inert diluent to form a homogeneous solution; mixing the homogeneous solution with a halide of titanium to form a mixture; precipitating a solid from the mixture in the presence of an auxiliary precipitant; treating the solid with a polycarboxylic ester to load the ester on the solid; and treating the ester loaded solid with the halide of titanium and the inert diluent. Component (B) is an organic aluminium compound, and component (C) is an organic silicon compound. The particle size of the catalyst can be adjusted by increasing the amount of the inert diluent at a low ratio of the epoxy compound to the phosphorus compound.
