The invention is applicable to the technical field of computers, and provides an application program file moving method and an application program file moving system. The method includes the steps: copying a source folder of to-be-moved application program files to a preset target folder; when the source folder is successfully copied, deleting the source folder; when the source folder is unsuccessfully deleted, unlocking the application program files according to collected occupied information of the application program files; and when the application program files are successfully unlocked, deleting the source folder and setting up soft links of application files in the target folder. By the aid of the method, according to the collected occupied information of the to-be-moved application program files, when the source folder of the application program files is unsuccessfully deleted, and the application program files are subjected to unlocking, so that the application program files are moved, the problem of low moving success rate is solved, moving operations of the application program files are simplified, automation degree of moving the application program files is improved, and the success rate of moving is increased.

The invention provides a combined carrying device special for medical magnets, and a storage device and a carrying method of the combined carrying device. The combined type carrying device special forthe medical magnet comprises two bottom beams connected with the medical magnet through bolts; four lifting frames inserted into the through cavities of the two bottom beams respectively, wherein each lifting frame comprises an inserting beam part, a transition part and an annular hole part; four lifting mechanisms inserted into the annular hole parts of the four lifting frames respectively, wherein each lifting mechanism comprises a cylinder body, a manual pump head and a piston column; four moving vehicles arranged below the four lifting mechanisms respectively, wherein a circular groove isformed in the upper end face of each moving vehicle, the lower end of each lifting mechanism correspondingly penetrates through the annular hole part, the piston columns are inserted into the circular grooves, and a through hole is formed in the side face of each moving vehicle; and four pull rods rotatably connected with the four moving vehicles respectively. The combined type carrying device and method special for the medical magnets, which are provided in the invention, are safer, more stable and more convenient.

The invention provides a preparation method of aza-bicyclic [2, 2, 1] hepta-5-alkene-3-ketone. The preparation method includes the steps: S1) performing hybrid reaction on 1, 3-cyclopentadiene and cyanide under the condition of presence of crosslinked polystyrene sulfinic acid sodium to obtain a bicyclic compound; S2) hydrolyzing the bicyclic compound to obtain the aza-bicyclic [2, 2, 1] hepta-5-alkene-3-ketone. Compared with the prior art, the crosslinked polystyrene sulfinic acid sodium serves as a polymer-immobilized catalyst and can be recycled, the reaction post-treatment operation process is simplified, only simple filtration is needed, reaction yield is improved, cost is reduced, and environmental pollution is decreased.

The invention belongs to the technical field of public intelligent equipment, and aims to solve the problem that an existing self-service washing machine cannot be used under the condition that a useronly carries clothes and does not carry other articles. Therefore, the invention provides an off-line operation self-service clothes processing system. The system comprises identity recognition equipment and a plurality of pieces of clothes processing equipment; the identity recognition equipment comprises a control device, an identity recognition device, a memory storage device and a local areanetwork module; the local area network module communicates with the plurality of pieces of clothes processing equipment, and the identity recognition device can recognize identity feature informationof a user; the memory storage device can store identity characteristic information of a user; and the control device can match the identity characteristic information of the user identified by the identity identification device with the identity characteristic information of the user stored in the memory storage device. According to the invention, a user only needs to carry clothes to treat the clothes, the steps are simplified, the operation time is saved, and the user experience is improved.
