Abstract: The present disclosure relates to a searchable encrypted data sharing method and system based on blockchain and homomorphic encryption, which protects security of sensitive data on the blockchain and realizes searchable and homomorphic calculation of data ciphertext. According to the present disclosure, a data owner encrypts the generated sensitive data and the keywords extracted according to the data with his own key, and then sends the encrypted transaction information to the cloud server. The cloud server verifies the identity of the data owner. If the verification succeeds, the uploaded ciphertext data is stored on a local server, and a ciphertext index, keyword ciphertext and related evidences of the data storage are uploaded to an alliance chain. The alliance chain node verifies the consistency of the uploaded transaction information, and if the verification succeeds, the transaction information is recorded.

Abstract: This invention discloses digitally printed plate, the manufacturing method and applications thereof, is characterized in that the digitally printed plate is of respectively from top to bottom surface lacquer layer, texture layer, second wear layer, first wear layer, pattern layer, bottom lacquer layer, base layer. The digitally printed plated has various patterns, with sufficient materials, printing unrepeatable stereoscopic pattern is possible, so it can satisfy customers' personalized customization requirements, without wasting abundant time or cost, and with process reduced, production efficiency is improved, enabling order manufacturing order insert and sample making at any time.

Abstract: The invention discloses a high strength fireproof board, which has two structures. The first structure is a three-layer hot pressed composite structure, which is composed of fiber layer, foaming fiber layer and fiber layer respectively from top to bottom, and the second structure is composed of hot-pressed fiber layer. The invention also discloses a wear resistant fireproof decorative panel consisting of a high strength fireproof board which is hot pressed at one time, or can be hot pressed twice, or composite molded after glue coated. The invention also discloses a manufacturing method for high strength fireproof board and wear resistant decorative panel based on high strength fireproof base board. The stated high strength fireproof board and wear resistant decorative panel are made of thermosetting resin and have the characteristics of flame retardant, wear resistant, high, and low temperature resistant, sound absorbing and antistatic.

Abstract: A method for controlling wavelengths of a multi-path laser is provided. The method includes: obtaining a difference between an actual output wavelength and a target output wavelength of each laser (S601); obtaining a corrected control amount of a temperature controller of each laser by decoupling calculation according to the difference (S602); and determining a die temperature of each laser according to the corrected control amount of the temperature controller (S603). A system for controlling wavelengths of a multi-path laser includes a multi-path laser (10), a difference module (12), a decoupling module (14), and a temperature control module (16).
