Abstract: A heating assembly and an aerosol generation device are provided. The heating assembly includes a heating body. Several heat generation portions serve as a sidewall of the heating body. The several heat generation portions are connected end to end in sequence and at least partially spaced apart from each other. The several heat generation portions that are spaced apart from each other are configured to guide a current to flow along a preset path. The several heat generation portions cooperatively define an accommodating cavity for accommodating an inhalable material and for air circulation.

Abstract: A control method and a control device of an optional paper tray are provided. The control method is applied to an image forming device, and include: according to a position of a bottom plate of the optional paper tray, determining whether a triggering condition for lifting the bottom plate is met; and using a paper feeding driving unit of the optional paper tray to drive the bottom plate of the optional paper tray to be lifted when the triggering condition for lifting the bottom plate is met. The paper feeding driving unit is used to transport paper in the optional paper tray.

Abstract: A parallel data access method for massive remote-sensing images includes: 1) segmenting a remote-sensing image to be processed using a set grid system, data in each grid corresponding to a data block; 2) collecting a data access log of an underlying distributed object storage system Ceph in a past period of time, and measuring a load index of each Ceph cluster and a load index of each pool; 3) selecting a pool with a minimum load in a Ceph cluster with a minimum current load to serve as a storage position of a current data block, and writing each data block into a corresponding pool; 4) returning a data identifier dataid and a data access path of the remote-sensing image; and 5) storing metadata of each data block in a metadata database. The method can support rapid and high-concurrency read and write of large-area data of a grid data block.

Abstract: A voice call transfer method includes when a target device receives an incoming voice call as a called party, displaying, on a call application interface, a device identifier of a first device that can perform voice call transfer, receiving a selection operation performed on the device identifier, triggering the target device to enter a voice call transfer mode, and sending first voice data from a calling party device to the first device when it is determined that the target device performs a voice call with the calling party device and is in the voice call transfer mode, so that the first device plays the first voice data.

Abstract: Provided are a drill-power-based directional hydraulic fracturing system for downhole quick slotting and a method thereof. The directional hydraulic fracturing system includes a water injection pump, a high pressure rubber pipe arranged on the water injection pump is in communication with a drill, a dedicated sealing drill rod for hydraulic fracturing is arranged on the drill, a front segment of the drill rod may be connected with a directional borehole sealer through threads and a sealing ring is provided at the threaded connection. The main steps include drilling, slotting, borehole sealing and fracturing. Firstly, a drill-cut integrated tool is installed at a front end of the drill rod. After drilling is completed, hydraulic slotting, permeability improvement and pressure relief are performed without changing a drill bit. After slotting is completed, the drill bit is retreated, and the directional borehole sealer is installed and pushed to a predetermined position for efficiency sealing.
