Abstract: A weight determining method and a related apparatus, to reduce a beam gain loss caused by a beam selection deviation are described. The method includes receiving an uplink reference signal and obtaining a channel reciprocity parameter between an uplink channel and a downlink channel based on the uplink reference signal. The method further includes determining state information of the downlink channel based on the channel reciprocity parameter, carrier frequency information of the uplink channel, and carrier frequency information of the downlink channel. Moreover, the method includes determining a weight of a downlink reference signal based on the state information of the downlink channel.

Abstract: A connector includes an end protector and lead frames. Each lead frame includes a plurality of connection terminal groups and a shield layer. Each connection terminal group includes two connection terminals configured to transmit a signal. Each connection terminal has a first connection end that cooperates with insertion of a circuit board. The shield layer is configured to electromagnetically isolate connection terminal groups in adjacent lead frames. The end protector includes a conductive structure that is located between the first connection ends of the two connection terminals in each connection terminal group. In the foregoing technical solution, with the conductive structure that is on the end protector, a transmission path of a loop signal corresponding to a differential signal transmitted by each connection terminal group is improved, crosstalk between loop signals corresponding to different connection terminal groups is reduced, and communication effect of the connector is improved.

Abstract: Provided are a method and a system for processing a rare earth concentrate ore. The method comprises (1) mixing the rare earth concentrate ore and concentrated sulfuric acid, thereby obtaining a mixed slurry and a first fluorine-containing gas; (2) mixing the mixed slurry and an initiator liquid for acidolysis, thereby obtaining a clinker and a second fluorine-containing gas; (3) subjecting the clinker to leaching with water, thereby obtaining a leached slurry; (4) subjecting the leached slurry to a solid-liquid separation, thereby obtaining a filtrate and a leached slag, and recycling the leached slag to step (2) for acidolysis again.

Abstract: Provided is a device for continuously decomposing a rare earth concentrate ore. The device includes a body, a bidirectional propeller and a driving assembly. The body has a material inlet, two liquid inlets and two exhaust gas outlets disposed at the top of the body, two material outlets disposed at the bottom of the body and a heat preservation chamber provided inside a side wall of the body.

Abstract: A connector includes an insulation base, a terminal array, a metal shielding piece, and a first common grounding conductor (CGC). The insulation base has two surface. The terminal array is fastened on the insulation base and includes many rows of terminals. Each row of terminals includes a signal terminal and a ground terminal, both which penetrate the insulation base, and a metal shielding piece is between two adjacent rows of terminals. The first CGC is on one surface, two through holes (THs) are on the first CGC, the signal terminal penetrates the first TH and is insulated from an inner wall of the first TH, the ground terminal penetrates the second TH and is in contact with and conducted with at least a part of an inner wall of the second TH, and the metal shielding piece is in contact with and conducted with the first CGC.

Abstract: The technology of this application relates to a shielding piece, a female connector, and a connector assembly. The shielding piece includes a main body and a contact portion, and the contact portion is connected to the main body by using at least two elastic arms or a connecting portion. The connecting portion surrounds the contact portion, and forms, jointly with the contact portion, a convexity protruding from the main body. The at least two elastic arms are connected to the main body at a periphery of the contact portion along different directions, and a gap is formed between the main body and the at least two elastic arms. The contact portion is configured to abut against a ground terminal of a male connector.

Abstract: A test strip device exhibits visual changes, such as color changes, when there is a only slight difference in the composition of liquids such as gasoline, oil, ethanol and water. Such a slight liquid composition difference usually requires a sophisticated and expensive instrument to differentiate. The test strip consists of one and more than one inverse opal films deposited on a substrate and achieves this goal of differentiation in a simple, fast and energy-free manner.

Abstract: The present invention designs and synthesizes the ascorbyl ester derivatives of the aryl (ethanoic) propanoic acid non-steroidal anti-inflammatory medicaments, such as ibuprofen, ketoprofen and naproxen, and addition salt of the derivatives with pharmaceutical acid or pharmaceutical alkaline. The non-steroidal anti-inflammatory medicament which takes the ibuprofen as the representative is a common antipyretic analgesic medicament. The invention has remarkable antipyretic and analgesic effects and good safety except for anti-inflammatory effect, thus being not only suitable for adults, but also suitable for the elderly people, infants and children.
