Abstract: A device for preparing ultra-high purity zinc based on intelligently-controlled zone melting, including a slide platform connected with a screw through a servo control system to control movement of a heating-cooling device. A quartz tube is provided inside an induction heater to protect a melting zone. An infrared thermometer is connected to the heater, and configured to monitor temperature within the melting zone, and control power of the heater. A ring magnetic stirrer with non-contact circumferential rotation cooperates with coil to stir zinc melt. A water-cooling copper jacket is connected to two ends of the heater to cool a zinc bar, and its water inlet and outlet are connected with a water chiller. The infrared thermometer monitors temperature of the zinc bar and controls water flow of the cooling system. A lifting device is connected with a base cabinet to change inclined angle of the zinc bar.

Abstract: A process for treating aged oil by electron beam irradiation is disclosed, comprising the following steps: step 1, homogenizing the aged oil and then feeding the aged oil into a distributor; step 2, forming a liquid layer having a certain thickness on the distributor; step 3, installing and debugging an electron beam irradiation device on the distributor; step 4, installing and debugging a phased-array microwave emitter on the distributor after installing and debugging the electron beam irradiation device; step 5, turning on the electron beam irradiation device and the phased-array microwave emitter; and step 6, dividing the treated aged oil and then allowing the aged oil after dividing to enter an oil pool and a water pool for standing. Oil flows out from an upper layer of the oil pool, a lower layer of the oil pool flows back to an aged oil storage pool.

Abstract: A high-thermal conductivity composite material is AlNp/ZA27 composite material, including 2%, 4%, 6%, or 8% by volume of aluminum nitride (AlN) ceramic particles and zinc-aluminium-27 (ZA27) alloy. The ZA27 alloy includes 70.52-71.08% by weight of Zn, 25.58˜27.65% by weight of Al, 1.27˜3.45% by weight of Cu, and 0.50% or less by weight of Mg. In the preparation of the high-thermal conductivity composite material, an as-cast AlNp/ZA27 composite material is subjected to homogenizing annealing and reciprocating extrusion.

Abstract: A biodegradable Zn—Mg—Bi zinc alloy and a preparation method thereof. The method including: melting magnesium under an inert atmosphere to obtain a magnesium melt; adding bismuth particles to the magnesium melt followed by reaction under stirring and heat preservation treatment to obtain a Mg—Bi alloy melt; allowing the Mg—Bi alloy melt to stand in a furnace; subjecting the Mg—Bi alloy melt to refining, slagging-off, casting and demoulding to obtain Mg-50 wt. % Bi alloy ingot; melting zinc to obtain a zinc melt; adding the Mg-50 wt. % Bi alloy ingot and pure magnesium or pure bismuth followed by heating to a preset temperature, stirring and heat preservation to obtain a Zn—Mg—Bi alloy melt; allowing the Zn—Mg—Bi alloy melt to stand in a furnace followed by refining, slagging-off, casting and demoulding to obtain the biodegradable Zn—Mg—Bi zinc alloy.

Abstract: Disclosed are a method and an apparatus for matching between a transaction request and a response based on location of a transaction, wherein the method comprises: step S1: receiving, by a server, a transaction request from a first client, the transaction request including a transaction description, an upfront pricing for the transaction, location of the transaction, and a posting scope associated with the location of the transaction; step S2: after a receiver in the server successfully receives the upfront pricing for the transaction transferred from the first client, positioning, via a Location Based Service (LBS), locations of other clients based on the location of the transaction, and pushing the transaction request to a plurality of second clients within the posting scope; step S3: receiving, from one or more of the plurality of second clients, one or more responses to the request, and forwarding the one or more responses to the first client to implement matching.

Abstract: A graphics system including a frame buffer having two or more buffers, a graphics processor and system memory. The graphics processor includes rendering logic, display logic and a buffer switch memory that stores an address. The display logic reads the address from the buffer switch memory and retrieves rendered data for display from one of the buffers. The rendering logic retrieves a next display list from the system memory after a continue indication is provided, renders the retrieved display list into another buffer, writes an address corresponding to the other buffer into the buffer switch memory and clears the continue indication. The continue indication may be a separate bit or a continue flag provided within each display list. The rendering logic sequences through the plurality of buffers in this manner to render a plurality of display lists. If only two buffers are provided, then the buffer switch memory includes an arm bit and the rendering logic sets the arm bit after rendering each display list.
