Abstract: Embodiments relate to a system for predicting thermodynamic phase of a material. The system includes a phase diagram image scanning processing module configured to scan a binary phase diagram for each material to be used as a component of a high-entropy alloy (HEA). The system includes a feature computation processing module configured to generate a primary feature and an adaptive feature.

Based on the attributes of different functions to be implemented in the energy trading and management platform, the platform is built by combining different advantages of blockchain technology and database technology. Deploy the functions of issuing transactions, matching transactions, and querying transaction information in Ethereum smart contract, store user registration information in a traditional database, and establish a mapping relationship between real information and lengthy blockchain accounts to make information of transactions on the market be displayed with real names. This method not only meets the needs of energy distributed transactions but also avoids the problem of incompatible string type data in Ethereum smart contracts which affects system performance. At the same time, the transaction data displayed with real names ensures the openness and legality of the transaction system.

Abstract: This invention involves a multi-energy distributed transaction and smart contract design method based on the Ethereum private chain. This method includes the following steps: 1) Setting the genesis node of the smart contract as an administrator node, while other nodes as user nodes; 2) Distinguishing system functions and account permissions between administrator nodes and user nodes. Only administrator nodes can add or delete the types of tradable energy in the blockchain through the energy switch function; 3) The user realizes multiple energy transactions at the same time, and the smart contract matches the information released by users based on the market supply and demand situation. This invention can effectively solve the problems of the centralization of the current energy trading system and insufficient security protection. At the same time, it provides an effective solution to the current limited development of blockchain technology in the field of multi-energy trading.
