Abstract: A media Parameter-modified method for realizing an adaptive expression of an arbitrary discontinuous surface, comprising the following steps: importing an initial forward model, importing anisotropic parameters; and setting a space step and a time step according to the initial forward model parameters; and then starting a stepped discretization of a free surface of the initial forward model; and using a corrected constitutive relationship to correct a first level parameter of the initial forward model; and bringing the corrected constitutive relationship into a displacement stress equation, and the influence of the free surface can be introduced in the case of the anisotropic media after series of operation. The present disclosure can make an accurate numerical simulation of a wave field near the discontinuous surface, and the accurate numerical simulation will contribute to the extraction and analysis of information from the seismic data.

Abstract: A display panel includes an active area; a fanout region; and a bonding region located on one side, away from the active area, of the fanout region. A driver chip is disposed in the bonding region. The driver chip includes a first side edge adjacent to the fanout region, a second side edge opposite to the first side edge, and two third side edges. The driver chip includes a plurality of output terminals disposed close to the first side edge. The display panel includes: a plurality of fanout lines located in the fanout region; and a plurality of gull-wing lines located in the bonding region. Part of the fanout lines extend from the fanout region to a region where the first side edge is located, and are electrically connected to the output terminals. Another part of the fanout lines are electrically connected to the output terminals via the gull-wing lines.

Abstract: A device and a method for transferring and storing a deep in-situ core in a sealed and pressure-maintaining manner includes a pressure vessel, a sealed storage vessel, a control system, a pressure regulation system and at least one spherical valve. The pressure vessel includes a first barrel and a first end sealing piston mounted at a first end of the first barrel and being slidable in the pressure vessel. The sealed storage vessel includes a second barrel and a second end sealing piston which is mounted at a first end of the second barrel. At least one spherical valve is connected between the first barrel and the second barrel. The pressure regulation system is configured for regulating an amount of water in the second barrel. The control system includes a first pressure sensor, a second pressure sensor, and a controller.
