Abstract: A method and apparatus for synchronously playing an image and an audio are provided. The method comprises: acquiring a play service request sent by a broadcast terminal; acquiring play image data and audio data corresponding to the play service request, the play image data being divided into a plurality of groups based on played content; and sending the play image data, the audio data, and information for determining a first corresponding relationship between each of the groups and an attribute of the audio data to the broadcast terminal, to enable the broadcast terminal to perform synchronization on the play image data and the audio data correspondingly to synchronously play the play image data and the audio data. Establishing the corresponding relationship between the audio data and the played content of each of the groups enables the broadcast terminal to accurately synchronize the played audio content and the displayed play image.

Abstract: Embodiments of the present disclosure provide a method and a device for training an acoustic model, a terminal device and a storage medium. The method includes: displaying a content card associated with an application function on a screen of a terminal device; and performing a switching operation on the content card currently displayed on the screen when detecting that a preset switching condition is satisfied.

Abstract: A device for generating electrical power, the device comprising a scroll expander with first and second scrolls configured to move relative to each other when a fluid is provided to an inlet at a higher pressure than a pressure at an outlet. The first scroll is configured to provide a magnetic field and the second scroll comprises one or more conductors in which electric currents are induced when the first and second scrolls move relative to each other.

Abstract: The invention provides a global optimization and dispatching method based on time scales. The method uses a target value system and a dispatch model. The global optimization and dispatching method takes input from the results from a variety of subtopics. The methods provide adjustment and optimization in accordance with the time scales that are given in the sub goal of each sub topic: long-term, mid-long-term, short-term, ultra short term and real time optimization. Smart distribution grid can improve operational efficiency, integrated application of new elements in the distribution network of distribution energy network, micro grid, energy storage device and non-linear loads. This invention is fully adapted to the smart grid trends, with a good prospective.

Abstract: An attached structure used in a touch display device is provided. The attached structure includes an attaching module, an attached module and an adhesive layer. The adhesive layer is disposed between the attaching module and the attached module to attach the attaching module and the attached module. A plurality of gas exhausting channels are formed on the adhesive layer such that a small amount of air is gathered in the gas exhausting channels in advance when the attaching module and the attached module are attached without being gathered between the attaching module or the attached module and the adhesive layer to affect the attaching result.

Abstract: A lighter includes a shielding frame including a wind shielding guard and two safety guards integrally and rearwardly extended from two sidewalls of the wind shielding guard respectively. The shielding frame has a top ceiling and a top flame gate formed thereon to align with a gas nozzle, wherein the wind shielding guard has a height that a root portion of the lighter flame is positioned below the top flame gate for preventing the lighter frame from being blown out. Each safety guard has a top edge rim horizontally extended from the top ceiling of the wind shielding guard to a position above a top circumferential edge of the respective driving wheel, such that the safety guards form as a physical barrier for preventing a thumb of a child from fully engaging with the driving wheels to drive the striker wheel to rotate.

Abstract: An ignition unit for a lighter includes a striker wheel sandwiched between two driving units wherein each of the driving units includes a driven gear element and a driving cap. The striker wheel urges against a flint with its toothed surface of generating sparks. One of the driving caps is normally rotated about the respective driven gear element in a free rotatably movable manner unless a downward force is intentionally applied on the driving cap while rotating the driving cap to drive the respective driven gear element and said striker wheel to rotate for striking against the flint to produce sparks.
