Abstract: The dual gate array substrate of the present disclosure includes a plurality of groups of dual gate lines, a plurality of data lines, a plurality of pixel pairs and a plurality of common electrode lines, each common electrode line is arranged between two pixel units in a same pixel pair and is connected to common electrodes of the two pixel units through two first vias; a layer where the common electrode line is located and a layer where a source/drain electrode of a thin film transistor is located are different layers and insulated from each other; the two first vias are on both sides of the data line.

Abstract: Disclosed are a transmission delay indication method and device. In the embodiments of the present disclosure, a network device determines a common transmission delay of at least one cell, and sends the common transmission delay to a terminal in the at least one cell. The common transmission delay is used for the terminal in the at least one cell to determine a transmission timing sequence with a network side.

Abstract: A method for blocking mine water inrush includes: grouting first slurry into an interface between the quaternary aquifer and the weathered bedrock aquifer in a fracture grouting manner until a first preset condition is met; forming a first water-resisting cushion after the first slurry is solidified; drilling a curve branch drill hole in the surface horizon downward; grouting second slurry into the curve branch drill hole in a downward grouting manner until a second preset condition is met; forming a second water-resisting cushion after the second slurry is solidified; grouting third slurry onto a top of the first water-resisting cushion in an upward grouting manner until a third preset condition is met; forming a third water-resisting cushion after the third slurry is solidified; wherein the third water-resisting cushion is located on the top of the first water-resisting cushion.
