Abstract: A photographing method and an electronic device are provided, so that a to-be-photographed target can continue to be tracked after the to-be-photographed target returns to a shooting image, to improve accuracy of focusing performed during photographing of a moving object. The method includes: displaying a first image including a first object and a tracking indicator that is associated with the first object, the tracking indicator indicating that the first object is a tracked target; displaying a second image that does not include the first object or the tracking indicator; displaying a third image including the first object; automatically setting the first object as the tracked target and displaying the tracking indicator associated with the first object; and automatically focusing on the first object when displaying the third image.

Abstract: A lithium-ion battery separator with high-temperature resistance, a preparation method thereof and a lithium-ion battery prepared therefrom fall within the field of lithium-ion battery separators. The separator has a thickness of 3.5-30 ?m, a porosity of 30-80%, an adjustable pore size of 20-2000 nm, a biaxial tensile strength of ?50 MPa, an air permeability of ?400 s/100 cc, and a breaking temperature of ?160° C. The preparation method comprises the following steps: mixing, melting, and plasticizing 20%-60% of a polypropylene main material, 2%-10% of a solubilizer, 30%-80% of a solvent. 0.1%-5% of a nucleating aid and/or 0.1%-1% of an antioxidant, carrying out twin-screw extrusion, carrying out thermally induced phase separation to obtain a cast sheet, and carrying out cast sheet stretching, extraction, and post-treatment or directly carrying out extraction and post-treatment.

Abstract: The invention provides a reconciliation system and method based on a hybrid cloud computing platform. The reconciliation system includes: a bill data processing module, processing data from a public cloud billing API or downloaded bill detailed files; a data monitoring processing module, processing the data collected from the resource pool of the computing management system resource pool and task resource requested; a task data processing module obtaining and processing task data from the task database of the computing scheduling system, and calculating the core hours that the tasks consumed; a statistical alarm module combining the resource data table obtained by the above three modules to obtain the utilization ratio and difference range of the computing task packing can realize the reconciliation alarm and prediction for task core hours. The computing power demand for a large number of existing tasks can be used to guide the purchase of computing power in the future.

Abstract: A carpet metal sticker for fixing a carpet and a carpet fixing structure, the carpet fixing structure is used to fix at least four carpet. The carpet includes a composite back layer. The carpet fixing structure includes at least one carpet metal sticker. Four corners of the four carpets are respectively attached to the four hook fixing-carpet areas. A length of each of the hook needles taken along an extension direction thereof is equal to a thickness of the composite back layer. When the carpet is fixed onto the hook fixing-carpet areas, the hook needles are inserted into the composite back layer and is bent and fallen, and the hook needles are contained in the composite back layer. The hook needle can buckle the composite back layer of the carpet so as to fix the carpet onto the carpet metal sticker and avoid the phenomenon of warping and displacement of the carpet.
