The invention relates to a portable shoelace tying method and a fastener. The method comprises the following steps: a single shoelace is folded in a semicircular manner to form a double-strand shoelace with two shoelace ends at one end; after the double-strand shoelace rounds shoelace buttons, the two shoelace ends penetrate and round eyelets of one shoe from back to front sequentially and respectively in an interlaced way; the two shoelace ends are inserted and fixed in a shoelace end locking sleeve at the front end of a shoe in a rounding way, the semicircular folding part of the shoelace is kept behind the shoelace button and naturally placed, and an annular elastic band is tied near the semicircular folding part of the shoelace; and the semicircular folding part of the shoelace is hung on the fastener, and the tying and the untying of the shoelace are realized through the fastener. The portable shoelace tying method has the advantages of convenience, quickness, attractive appearance and practicability, and is beneficial to reduction of unsafe hidden dangers, avoidance of unsafe problems brought to soldiers, athletes and manual producers due to loosening of the shoelace, and reduction of redundancy of shoelace knots, rings and ends formed by shoelace tying.

The invention provides a section cutting hole tunneling method of a mine, and relates to the technical field of mining. The section cutting hole tunneling method of the mine comprises the following steps that 1,the actual condition of a working face coal seam in an early tunneling process is judged, a tool is advanced from the top left corner of a roadway to cut a socket groove through a heading machine, a working face is sequentially cut in a circulating and reciprocating mode by using a cutting mode which is conducted from the top to the bottom and from the left to the right, and the two sides of the roadway and a bottom plate are repaired; and 2, inspection is performed on the heading machine, a cutting system is started under the condition of no load, and a cutting head of the headingmachine is enabled to rotate. According to the section cutting hole tunneling method of the mine, the total width of the cutting hole is 7 meters, the length is 150 meters, the width of the roadway isreduced firstly, and tunneling is conducted for 150 meters with the width of 3.5 meters and the roadway is connected with an air return way in a through mode, so that the tunneling speed can be accelerated, the rapid breakthrough of the cutting hole and the air return way can be brought forwards, the safety during tunneling operation is increased, the use of a local fan can be stopped in advanceafter the breakthrough, and the energy-saving effect is achieved.

The invention discloses a visual tracking method based on multi-cue fusion, which belongs to the technical field of information. The method comprises the following steps: a) determining a tracking window comprising a target region and a background region in a first frame of a video sequence; b) obtaining a color feature probability distribution graph, a position feature probability distribution graph and a motion continuity feature probability distribution graph of the previous frame from the second frame; c) adding the three probability distribution graphs in a weighed manner to obtain a total probability distribution graph; and d) using a CAMSHIFT algorithm to obtain the coordinates of a central point of the tracking window of the current frame in the total probability distribution graph. The method can be used in human-computer interaction, visual intelligent surveillance, intelligent robot, virtual reality technology, model-based image encoding, content retrieval of streaming media and other fields.

The invention discloses a large-inclination-angle trash rack-shaped suspension sliding form and a construction method thereof, which include a mold body system and a suspension system; the mold body system includes a trash rack-shaped template formed by splicing panels, and a Ribs and supporting trusses; a working platform is laid on the upper surface of the formwork system; a hydraulic control system is installed on the working platform; the suspension system includes a suspension support frame of a truss structure, and the suspension support frame is fixed on the trash block through anchor bars and steel supports The platform on the grid; there are multiple sets of suspension rods connected to the bottom of the suspension support frame, and the bottom end of the suspension rods is connected to the truss of the form system through a hydraulic jack; the suspension angle of the suspension rods is consistent with the inclination angle of the trash rack; the form system There is a concrete conveying system along the installed steel bars and tracks at the top; there is a missing maintenance system connected to the lower part of the formwork system; the steel bars are bound in place at one time, the installation of grid grooves and tracks is completed at one time, and the second phase of concrete construction is canceled. The characteristics of one-time forming of hanging sliding form.
