  • Patent number: 10516666
    Abstract: An authentication method is provided. The authentication method includes receiving a login request from a client terminal. The login request may be generated based on an identification feature of the client terminal, and the login request may include account information associated with the client terminal. The method may further include identifying the identification feature based on the login request, determining whether a database associated with a server includes the identification feature and the account information, generating login status information based on a result of the determination and sending the login status information to the client terminal, and if the login status information indicates a login success of the client terminal, initiating data communications with the client terminal.

  • Publication number: 20180339948
    Abstract: Disclosed are a microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt and a method of preparing the same, which relate to the technical field of production of water-soluble fertilizers. The microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt is prepared from potassium nitrate concentrate, urea, industrial monoammonium phosphate, water-soluble ammonium polyphosphate, potassium sulfate, EDTA-Fe, EDTA-Zn, EDTA-Mn, boric acid and ammonium heptamolybdate. The microgranular water-soluble fertilizer product co-produced from potassium nitrate by tower melt has balanced and stable nutrients. The product is microgranular, has a smooth appearance, is less susceptible to agglomeration, is easy to be absorbed and utilized by crops, and contains a full range of nutrients. In addition, the product is produced by a process employing fully automatic dispensing equipment, which mainly integrates “dispensing, mixing and packaging” and is fully automated.
