Abstract: The present disclosure provides method and apparatus for automatically generating motions of an avatar. A message in a session between a user and an electronic conversational agent may be obtained, the avatar being a visual representation of the electronic conversational agent. At least one facial animation and/or body animation may be determined based on at least one part of the message. At least one motion of the avatar may be generated based at least on the facial animation and/or the body animation.

Abstract: A fluidized catalytic conversion method for maximizing the production of propylene includes the steps of: 1) contacting a heavy feedstock oil with a catalytic conversion catalyst having a temperature of 650° C. or higher for reaction; 2) contacting a hydrocarbon oil feedstock having an olefin content of 50 wt % or more with the catalytic conversion catalyst after the reaction of step 1); 3) separating a first catalytic cracking distillate oil and a second catalytic cracking distillate oil from the resulting reaction products; 4) separating an olefin-rich stream from the first catalytic cracking distillate oil; and 5) recycling the olefin-rich stream. The method can effectively improve the yield of propylene and realize an effective utilization of petroleum resources.

Abstract: A fluidized catalytic conversion method for producing light olefins includes the following steps: 1) introducing an olefin-rich feedstock into a fluidized catalytic conversion reactor, and contacting with a catalyst having a temperature of 650° C. or higher for reaction; 2) separating the reaction product vapor obtained by the reaction to obtain a stream comprising C5+ olefins; and 3) recycling at least a part of the stream comprising C5+ olefins to step 1) for further reaction. The fluidized catalytic conversion method can effectively improve the yield of light olefins, improve the selectivity and improve the ethylene/propylene ratio of the product.

Abstract: The present disclosure relates to a program verification method and apparatus, a platform, a user terminal, and an online service system, includes: acquiring a root evidence of a server-side program from a blockchain network, and acquiring a verification evidence of the server-side program from a server side, where the root evidence is written into the blockchain network after server-side program review succeeds, and the success of the server-side program review indicates a data processing method of the server-side program satisfies a preset data processing rule; verifying whether the root evidence and the verification evidence are matched, where the root evidence and the verification evidence being matched indicates the server-side program is a program that is operated in a TEE of a computer and is not modified after the root evidence is written into the blockchain network; and determining to connect a user-side program to the server-side program.

Abstract: The present disclosure provides a blockchain system and a permission management method thereof. The blockchain system includes a plurality of node groups, group account information of each node group is stored in a block of the blockchain, the group account information includes a permission set of the node group, and each node in the node group has all permissions in the permission set of the node group; and the permissions of the nodes in each node group are controlled by a management node in a parent group of the node group; and the permissions in the permission set of each node group are more than those of the permission set corresponding to a child group of the node group; and the member account information of each node is stored in the block of the blockchain, and the member account information includes the permissions of the node.

Abstract: A blockchain mining method, device, and a node apparatus are used to solve the technical problem of unequal distribution of mining opportunities for node apparatuses in a blockchain network. The method comprises: acquiring a current block number of the blockchain; judging whether a hash slot corresponding to the block number is consistent with a hash slot corresponding to the node apparatus, wherein the node apparatuses in the blockchain network are distributed in N hash slots by means of a hash algorithm, and N is a positive integer greater than or equal to 2; and determining whether the node apparatus performs mining this time according to a judgment result.

Abstract: A registration and authorization method, device and system is used for solving the technical problem of relatively low safety of the existing authorization technology. The method is applied to an authorization server, the authorization server is a node in a blockchain network and stores a blockchain composed of a plurality of blocks, each block is used for storing authorization information, and the method comprises: receiving a registration request message sent by a user device, wherein the registration request message includes identification information, and the identification information is used for performing identity verification on a user; assigning authorization information to the user, wherein the authorization information is used for indicating a service that the user can access; and writing the identification information and the authorization information into the blocks of the blockchain through the authorization server.

Abstract: A permission control method, apparatus and system for a blockchain, and a node device. The method comprises: writing a preset correspondence between account roles and permissions into a block of a blockchain; determining a role of a target account configured to a user node to be added to the blockchain; and controlling, according to the correspondence and the role of the target account, a permission of the user node configured with the target account. In the method, by setting roles and permissions of blockchain accounts, user nodes configured with different accounts perform corresponding operations according to roles and permissions of the user nodes, so that only accounts having corresponding permissions can access a blockchain network, synchronize data on a blockchain and acquire data within a permission range; blockchain data is protected, and the security and privacy of the blockchain data are ensured.
