Embodiments of this application disclose a channel arbitration method and an apparatus. After receiving an uplink grant for a first SIM card, a physical layer scheduler of a terminal device configures a transmission service priority of the first SIM card in a front-end arbiter as a first predicted priority, and configures PUSCH transmission information for the front-end arbiter based on the uplink grant, where if packeting for uplink scheduling is completed before an arbitration time point, the transmission service priority of the first SIM card is updated to a service priority of a MAC layer; the front-end arbiter arbitrates a transmission service of the first SIM card based on the PUSCH transmission information and the transmission service priority; and further, if the first SIM card is performing a voice service and the arbitration continuously fails, fallback to a DSDS 2.0 mode is triggered.

Channel arbitration method and apparatus

A cobalt-chromium alloy stent comprising several main body units, wherein each main body unit is composed of several supporting rings connected by flexible ribs and the adjacent main body units are connected by several connecting ribs. A drug eluting stent comprising the cobalt-chromium alloy stent and a drug coating containing arsenic trioxide and tacrolimus. The drug release curves of the two composite drugs of arsenic trioxide and tacrolimus used in the present invention are adjusted, so that the inflammatory response of vascular endothelial cells and the proliferation behavior of vascular smooth muscle cells are effectively inhibited, and the vascular restenosis rate is reduced.

The present disclosure relates to a multi-stage temporary plugging fracturing method based on a stress cage effect, a device thereof and a storage medium, which are applied to the technical field of oil and gas exploitation. The method includes: determining a plugging point by acquiring a weak stress position on a major fracture; determining the consumption of temporary plugging deflection fluid by calculating a net pressure in a fracture that needs to be increased to generate a branch deflection fracture at the position where a principal stress is minimum; plugging a weakest stress position in the major fracture to form an artificial shielding layer, preventing subsequent fluid pressure from passing forward, thereby changing a geostress field near this position, thus forming an additional induced stress field near the weak position, generating a stress cage effect, and realizing formation of a multi-stage temporary plugging branch fracture in vertical wells.
