Abstract: In a multi-channel signal encoding method, a current frame includes a first sound channel and a second sound channel. First group information of M blocks of the first sound channel and second group information of M blocks of the second sound channel are obtained. When the first group information and the second group information meet a preset condition, first adjusted group information and second adjusted group information are obtained based on the first group information and the second group information. Then, a first to-be-encoded spectrum is obtained based on the first adjusted group information and the spectrums of the M blocks of the first sound channel. Similarly, a second to-be-encoded spectrum may be obtained. Finally, the first to-be-encoded spectrum and the second to-be-encoded spectrum are encoded by using an encoding neural network to obtain a spectrum encoding result. The spectrum encoding result may be carried by a bitstream.

Abstract: A calculation system for predicting a proppant embedding depth based on a shale softening effect is provided, including a sampling test terminal, a scheduling module, a monitoring module, and a calculation module, wherein the scheduling module, the monitoring module, and the calculation module are connected in communication, and the monitoring module is connected to an external operating system through a wireless network, wherein the external operating system is configured to perform a hydraulic fracturing operation and receive a first control signal and/or a second control signal from the monitoring module. The sampling test terminal is configured to test the samples and obtain test data. The scheduling module is configured to determine a target construction parameter.

Abstract: The present disclosure provides a herbicide composition and a preparation method and an application method thereof, and relates to the technical field of herbicides. The herbicide composition includes pinoxaden and a cyclic lactone compound. The cyclic lactone compound is five-membered cyclic lactone and/or six-membered cyclic lactone. The herbicide composition solves the technical problems of poor chemical stability and precipitation due to crystallization at low temperature of existing pinoxaden emulsifiable concentrate formulations. In the herbicide composition, the cyclic lactone compound is used in combination with the pinoxaden, such that not only the solubility of the pinoxaden is improved, but also a chemical stabilization effect of the pinoxaden is effectively improved, and the problems of precipitation due to crystallization at low temperature and chemical stability of the pinoxaden emulsifiable concentrate formulations are solved.

Abstract: The present disclosure discloses a cutting structure and a sewing process for back wearing protective clothing. An eye gap is formed in the top of a cap cutting piece. An upper neck interface is formed in the bottom of the cap cutting piece. Cap top seams which are in left-right symmetry are formed in the two sides of the eye gap. Cap openings are formed in the two sides of the lower part of the cap cutting piece. An upper right sleeve seam is formed in the upper end of one side of an upper section cutting piece. A lower right sleeve seam is formed in the lower end of one side of the upper section cutting piece. An upper left sleeve seam is formed in the upper end of the other side of the upper section cutting piece. A lower left sleeve seam is formed in the lower end of the other side of the upper section cutting piece.
