Abstract: Disclosed is a method for synthesizing a diglyceride. The diglyceride is obtained by mixing a fatty acid donor with glycerol, partial glyceride lipase, and monoglyceride lipase by adding water, then subjecting the same to an esterification reaction, with a reaction time of 8 to 24 hours, and further separating and purifying the same. In the present invention, monoglyceride lipase is used to promote the reaction efficiency of partial glyceride lipase in the esterification reaction, so as to increase the synthesis rate of diglyceride. Compared with a single enzyme, the synthesis time is shortened by half or more, and 45.50% or more of diglyceride is obtained after the esterification reaction. Since substantially no triglyceride is generated in products, the content of DAG reaches 98% or more after the same has been purified by means of molecular distillation.

Abstract: This application discloses a sounding reference signal (SRS) sending method, a resource configuration method, and a related device. It may be applied to a scenario where there is a discrepancy between uplink and downlink antenna structures of a terminal device. In the method, the terminal device sends a first SRS using a first SRS resource configured by a network device, and sends a second SRS using a second SRS resource configured by the network device, where a transmission beam of the first SRS resource is different from a transmission beam of the second SRS resource. This satisfies a requirement for measuring downlink channel state information in a scenario where there is a discrepancy between the uplink and downlink antenna structures of the terminal device. Consequently, downlink transmission weights can be calculated, thereby implementing SRS-based downlink transmission and increase cell-level or UE-level capacity.
