Abstract: The present invention belongs to the field of drug preparation and detection, and particularly discloses a preparation method for a Eucommia ulmoides Oliv. leaf extract. The extract is obtained from Eucommia ulmoides Oliv. leaves (the mixture of the Eucommia ulmoides Oliv. leaves and Eucommia ulmoides Oliv. male flower) by enzymolysis and extraction of ethanol and water, and can effectively solve the problem that the extract is not easy to spray dry (the Eucommia ulmoides Oliv. leaves contain colloidal substances). The pharmacodynamic experiment proves that the Eucommia ulmoides Oliv. leaf extract has good effect of protecting the health of the renal function. The present invention also develops a detection method for the extract, which not only realizes the quality control of the extract, but also has the advantages of good repeatability and stability.

Abstract: Embodiments of the present invention disclose a node scheduling method, where the method includes: configuring, for a node, a working period matched with a performance indicator of the node, where duration of the working period is an integer multiple of duration of a super frame, and the super frame is a super frame corresponding to a beacon frame in a network in which the node is located; and sending, to the node, an updated beacon frame that includes information about the working period, so that the node acquires the information about the working period from the updated beacon frame, receives a working beacon frame, establishes a super frame corresponding to the working beacon frame until the working period ends, and then repeats the receiving a working beacon frame and establishing a super frame corresponding to the working beacon frame until the updated beacon frame is received again.

Abstract: The present invention provides a channel selection method and an apparatus, relates to the field of communications, can improve channel scan and detection efficiency. The method includes: randomly selecting m channels from a preset channel page; determining, from the m channels, a working channel and a spare channel that meet a preset condition; scanning, the working channel of the first superframes and the spare channel of the first superframes in an inactive period of each of the n first superframes according to preset first scan duration, to acquire n energy levels of the working channel and n energy levels of the spare channel; and determining, in an inactive period of the nth first superframe, a working channel for sending a second superframe and a spare channel of the second superframe according to the n energy levels of the working channel and the n energy levels of the spare channel.

Abstract: Embodiments of the present invention provide a data processing method, a coordinator, and a node device. The coordinator receives a data frame sent by the node device, where the data frame includes service data; the coordinator determines whether the service data is within a set data confidence interval; and if the coordinator determines that the service data is beyond the data confidence interval, the coordinator sends a questioned-data frame to the node device, where the questioned-data frame carries the service data, so that the node device confirms correctness of the service data.

Abstract: Embodiments of the present invention disclose a beam codebook generation method, includes: calculating a first array response factor of a reference beam according to the number of actually generated beam signal channels, and calculating a second array response factor of the reference beam according to the preset number of target beam signal channels; performing radiated power normalization processing on the first array response factor to obtain a first radiation factor of the reference beam, and performing radiated power normalization processing on the second array response factor to obtain a second radiation factor of the reference beam; performing normalization processing on the first radiation factor and second radiation factor to obtain a beam codebook of the reference beam; and performing rotation processing on the obtained beam codebook of the reference beam to obtain a beam codebook of one or more other beams except the reference beam in the target beams.
