This invention relates to a method and a system for asking to protect dynamically altering user location frequencies, which calls different algorithm modules combining with the movement state of a mobile user and the quality standard QoS demanded by the user to dynamically alter the location frequencies of the mobile user so that the historic trace recorded of the user is more accurate.

The invention discloses an underwater blasting construction method for a deep-water inclined bare rock foundation, and relates to the field of bridge deep-water foundation construction. The method comprises the following steps that before formal blasting, a depth measuring instrument is adopted and RTK-GPS is arranged to conduct plane and elevation three-dimensional scanning-measuring on an original river bed in a blasting area, and a reasonable blasting design is made according to foundation geological survey and three-dimensional scanning-measuring data; underwater blasting is constructed through a peripheral slope-making method, blasting is conducted in sequence from the low position to the high position of the river bed, vertical layering is avoided, drilling is conducted to the designed hole depth (including the over-drilling depth 1-2.0 m) each time, blasting is conducted once a day, and finally slag is removed at a time; and after a drilling-blasting ship is positioned through a six-cable positioning method, a casing is put downwards, underwater drilling is conducted through a down-hole drilling machine, a hole is filled with a processed explosive roll and blocked after the hole is cleaned, and blasting operation is carried out after blasting network connection. The method has the characteristics of fast positioning, low cost, less construction interference, rapid construction progress and the like, and is suitable for underwater blasting construction of the deep-water inclined bare rock foundation.

The invention discloses a piston workblank casting head continuous automatic sawing machine tool which comprises a machine tool body. A Z-directional running device is arranged on the machine tool body. The Z-directional running device is movably provided with an X-directional running device which is movably provided with a cutting motor pulling plate. The cutting motor pulling plate is provided with a cutting motor. A cutting tool bit is arranged on the main shaft of the cutting motor. The piston workblank casting head continuous automatic sawing machine tool further comprises a four-station rotating table arranged on the machine tool body. Four location pins are distributed uniformly on the table facet of the four-station rotating table along the circumferential direction. Two sets of clamps are arranged above the machine tool in a matching manner. According to the piston workblank casting head continuous automatic sawing machine tool, the continuous cutting of the piston workblank top riser and the side pouring gate can be achieved; the sawing position is accurate; the degree of automation is high; one person can manage multiple machines, thereby improving the working efficiency.

The invention relates to 3D printing equipment. The 3D printing equipment comprises a supporting frame, a printing assembly and a working box mechanism, wherein the printing assembly and the working box mechanism are integrally arranged on the supporting frame; the printing assembly comprises symmetrically-arranged discharging guide rails, a plurality of printing guide rails, a plurality of discharging mechanisms and a plurality of printing mechanisms, wherein the printing guide rails and the discharging mechanisms are arranged between the two discharging guide rails correspondingly, and one printing mechanism is arranged on at least one printing guide rail in a sliding mode; the two discharging guide rails are arranged on the two symmetrical sides of the supporting frame; and the workingbox mechanism comprises a working box and a jacking piece which are integrally arranged, wherein the jacking piece is used for jacking a bottom plate of the working box to ascend and descend in the vertical direction, and the working box and the jacking piece are movably arranged inside the supporting frame in a penetrating mode. The 3D printing equipment has the advantages of high printing efficiency and high product precision.

The invention discloses a novel double-sided processing device comprising a lower supporting plate; the upper end of the lower supporting plate is provided with an upper supporting plate through an upright post; a fixed frame is mounted in the middle of the upright post, and a plate to be processed is spliced into the fixed frame; at least two asymmetric locating holes are formed in the plate to be processed; and a mounting frame is arranged on a position, located above the fixed frame, on the upright post. A novel double-sided processing technology realized by using the double-sided processing device comprises the following steps of S1, preparing; S2, locating; S3, processing; and S4, material changing. By using the novel double-sided processing device and technology, double sides of the plate can be simultaneously processed, so that the locating frequency and locating errors can be reduced, processing errors between the double sides are further reduced and are reduced within the range of + / -0.05mm, the processing time can be shortened by more than 30%, and the economic benefits of enterprises can be better increased in a specific plate processing field.

The embodiment of the invention provides a positioning method and a terminal, and relates to the technical field of computers. The method comprises the following steps: at the arrival of a positioningperiod, obtaining an identifier of a current serving cell and the identifier of a historical serving cell of of the terminal, wherein the historical serving cell is a serving cell where the previouspositioning of the terminal is located; and when it is determined that the identifier of the current serving cell is inconsistent with the identifier of the historical serving cell, determining whether to start a positioning function according to the relationship between a neighboring cell of the current serving cell and the neighboring cell of the historical serving cell. At the arrival of the positioning period, whether to start the positioning function is judged according to the relationship between the current serving cell and the historical serving cell of the terminal and the relationship between the neighboring cell of the current serving cell and the neighboring cell of the historical serving cell, instead of starting the positioning function at the arrival of the positioning period, therefore the positioning times are reduced, the power consumption is reduced, and the endurance time is prolonged.

The embodiment of the invention discloses a positioning method and apparatus. The method comprises the steps of judging whether the current application meets a first positioning condition or not afterreceiving a current positioning request sent by a current application; judging whether the current application meets a second positioning condition corresponding to the current positioning request ornot if the current application does not meet the first positioning condition; and returning pre-stored information to the current application if the current application does not meet the second positioning condition.
