A tree structure is used to represent a join order and used as an input of a neural network, and different first attribute matrices are allocated to different brother nodes in the input tree structure. This helps the neural network comprehensively learn information about the join order, obtain representation information capable of differentiating the join order from another join order, and predict costs of the join order accurately based on the obtained representation information of the join order. Then, an optimizer selects a join order with lowest costs for a query statement based on the costs predicted by a cost prediction module.

Abstract: A computer-implemented method for integrating a full wavefield inversion (FWI) solution with a non-FWI solution. Computational costs for generating a large bandwidth FWI solution, such as to 50 Hz, may be considerable. However, limiting the FWI solution to a narrower frequency band, such as up to 20 Hz, renders the FWI solution less useful. To remedy this, an FWI solution that is band limited, such as up to 20 Hz, is integrated with a non-FWI solution. The non-FWI solution may comprise seismic stacks or non-seismic data, and is directed to a different frequency band, with at least part of the non-FWI solution frequency band being greater than 20 Hz. In this way, bandwidth extension may be performed for at least one subsurface physical property parameter by combining a band limited FWI solution with a non-FWI solution.

Abstract: A method for detecting a qualified rate of a battery electrode sheet includes collecting a first weight corresponding to a to-be-detected electrode sheet, drying the to-be-detected electrode sheet in a drying apparatus for a preset duration and collecting a second weight corresponding to the dried to-be-detected electrode sheet, and determining a detection result of the to-be-detected electrode sheet based on a ratio of a drying difference to the second weight. The drying difference is a difference between the first weight and the second weight.

Abstract: A rolling device and a measuring device are disclosed. A rolling assembly in the rolling device is movably mounted on a bracket in a first direction (a) parallel to a working surface, and when a member to be rolled is placed on the working surface, the rolling assembly provides a rolling pressure to the member to be rolled.

Abstract: The invention provides a suspension modifier directly added into fracturing fluid for real-time proppant modification during fracturing and the application thereof, relating to the field of oil and gas production technologies. The suspension modifier is a controlled release nanoemulsion and comprises surface hydrophobic modifier, surfactant, cosurfactant and water. The suspension modifier is directly added into clear-water or active-water fracturing fluid while the proppant is added into water. After stirring, the suspension modifier is capable of self-assembling and being adsorbed on the proppant surface, so that the proppant surface becomes hydrophobic and aerophilic. The invention no longer requires the proppant to be pretreated, and the bubble-suspended proppant can be obtained directly by adding the suspension modifier to the clear-water or active-water fracturing fluid, and meanwhile adding the proppant to the fracturing fluid.
