Abstract: Provided are a lithium nickel manganese oxide composite material, a preparation method thereof and a lithium ion battery. The preparation method includes: a first calcining process is performed on a nano-oxide and a nickel-manganese precursor, to obtain an oxide-coated nickel-manganese precursor; and a second calcining process is performed on the precursor and a lithium source material, to obtain the lithium nickel manganese oxide, and a temperature of the first calcining process is lower than the second calcining process. A a lower temperature, the nano-oxide may be melted, a denser nano-oxide coating layer is formed on the surface of the precursor, so the oxide-coated nickel-manganese precursor is obtained. At a higher temperature, the nano-oxide, a nickel-manganese material and a lithium element may be more deeply combined. A problem that the nano-oxide layer is easy to fall off is solved, and cycle performance of the lithium nickel manganese oxide is greatly improved.

Abstract: Technologies for inter prediction for a block in a video are provided. In one example, a method includes: when a size of a current block satisfies a preset condition, parsing a bitstream to obtain a syntax element, where the syntax element includes at least an index of optimal candidate motion information of the current block; determining, based on the syntax element, to construct a first list or a second list for the current block, where the first list is a block-based candidate motion information list, and the second list is a subblock-based candidate motion information list; determining optimal motion information from the first list or the second list based on the index; and predicting the current block based on the optimal motion information. In this method, the block-based candidate motion information list and the subblock-based candidate motion information list are distinguished from each other. This effectively reduces transmission costs of the optimal candidate motion information.

Abstract: The present disclosure relates to a digital control device based on artificial intelligence, belonging to the technical field of intelligent control. The digital control device based on artificial intelligence used by the present disclosure can comprehensively monitor the environmental data including temperature, humidity, smoke concentration, oxygen content, infrared temperature signals, etc. in real time by providing a control system, an environmental monitoring system and an actuating system, and generate control instructions through the monitored environmental data so that the actuating system can make corresponding actions accordingly, thus solving the problems existing problems in the prior art that the monitoring comprehensiveness is low, misjudgments or missed judgments are easy to occur, sensors cannot collect external environmental information in a time-sharing manner, and the practicability and service life are short.

Abstract: The present invention discloses a novel demister, comprising at least one demisting unit; wherein the demisting unit comprises a glow guide cylinder, a cyclone blade group mounted at a gas inlet of the glow guide cylinder and a liquid collection cylinder arranged outside the flow guide cylinder, wherein the liquid collection cylinder is provided with at least one glow guide cylinder, a water permeable structure is arranged on a side wall of the flow guide cylinder, and a gap is defined between an outer wall face of the flow guide cylinder and an inner wall face of the liquid collection cylinder and an interlayer chamber is formed.

Abstract: The present invention provides a blade group for demisting and dedusting, comprising a plurality of blades that are annularly arranged and a support mechanism for fixing the blades; wherein the blade comprises a section of curved plate, a cross section of the curved plate being a gradually-varied arc curve whose curvature increases progressively along an airflow direction. When gas carrying fine mist droplets or fine dust particles are passing through the blade group for demisting and dedusting, since the gas is different from the mist droplets or dust particles in terms of mass, separation of the gas from the liquid or dust under the effect of inertia is promoted. Especially, the gradually-varied blade curve enables the droplets or dusts to be captured and removed efficiently under the effect of a constantly-varied inertia and a drag force, which remarkably improves the working efficiency in combination with a washing device.
