A three-dimensional knitted side boundary device comprises an opening mechanism, a weft guiding mechanism, a weft sliding mechanism and a weft fixing mechanism. During use, the opening mechanism achieves warp opening through vertical stagger of different heald frames; the weft guiding mechanism enables weft to advance through a weft guiding rod and a weft guiding hook to pass through a weft opening, the weft sliding mechanism and the weft fixing mechanism drag the weft passing through the warp opening so that subsequent knitting and tightening can be facilitated, and especially when a weft taken preventing device is additionally arranged, the connection success rate of weft among vertical push rods and side boundary rods can be increased. The three-dimensional knitted side boundary device is simple in structure and high in working efficiency and precise control degree, the warp opening effect is good, the weft taken preventing function is good, and environment friendliness is good.

A method for controlling microscopic bubble nucleation in fluid polymer material production and its apparatus that utilizes a gas pipe disposed in the conveyance screw shaft of a conventional injection or extraction forming mechanism and, furthermore, a microbubble generating component (such as a microscopic perforation vented metal head or a microscopic perforation ceramic head, etc.) installed at the front extremity of the conveyance screw shaft. At the rear extremity of the gas pipe, a pressurization pump or a high pressure gas storage tank is admitted from an air intake opening, enabling the gas to be indirectly heated by an electric heater on the materials pipe. The high temperature gas is thereafter outputted from the microscopic perforations of the microbubble generating component such that high temperature microscopic bubbles are directly admitted into the section of liquid polymer material which is then uniformly amalgamated by the conveyance screw shaft and then deposited into a forming die. As a result, high pressure gas conveyance or termination is controllable; control is afforded as to whether each section of liquid polymer material is microbubble nucleated and amalgamated. The present invention thereby provides a microbubble nucleation production method in which the non-bubble nucleated is at the surface and the bubble nucleated is at the interior section when the liquid polymer material is poured into a forming die.

The invention belongs to the technical field of illuminating equipment, and discloses a heat dissipation illuminating lamp base convenient to overhaul. The lamp base comprises a dustproof lamp base, the top of the dustproof lamp base is provided with a connection shaft sleeve, a wire burying device and heat dissipation through holes, the wire burying device is arranged among the heat dissipation through holes, an installation support is installed in an inner cavity of the connection shaft sleeve, two sets of limiting clamping plates, an elastic part and a heat dissipation fan are arranged in an inner cavity of the dustproof lamp base, and an LED illuminating lamp installation plate is arranged between the two sets of limiting clamping plates. Since the wire burying device is arranged on the top of the dustproof lamp base, arrangement is convenient when an installation circuit inside the dustproof lamp base is connected to the outside world, connection between a connection circuit inside the dustproof lamp base and the outside world is clear, a circuit maintainer can overhaul and maintain or repair the circuit inside the dustproof lamp base in the later period conveniently, the maintenance or repair difficulty is reduced, the labor cost is reduced, and the later-period maintenance cost is reduced.

The invention relates to an indoor WLAN signal map drawing and mapping method based on image edge detection signal correlation. The method includes the step that firstly, RSS sequences collected by a random user are utilized to construct clustering charts of received signal strength (RSS) sequences through spectral clustering; secondly, a signal logic diagram of the random user in a located object area is constructed by the utilization of the image edge detection method; next, mapping between RSS clustering nodes in the signal logic diagram and area position nodes in a physical environment diagram is established according to corresponding mapping rules; finally, position estimation on a target user is achieve by the utilization of the mapping relation between the signal logic diagram and the physical environment diagram, and meanwhile the signal logic diagram and the physical environment diagram are drawn by the utilization of drawing techniques. The method has the advantages that the readability of the diagrams is improved, and the connection relation between the nodes in the signal logic diagram and the nodes in the physical environment diagram are clearer.
