The invention provides a method and device for superposition of a particle file and video. The method includes the steps of receiving a background check request upon the current particle file and searching the background of the particle file, establishing a two-dimensional panel and panel texture of the two-dimensional panel when the background of the current particle file is not searched, extracting a preset video file and adding the preset video file into a cache of the panel texture, and updating the background of the current particle file according to the cache of the panel texture and the two-dimensional panel. The method and device for the superposition of the particle file and the video can avoid that due to the fact that a video file is so big in size, a superposition result of the particle file and the video is discontinuous.

The present invention is applicable to the field of cultivated land resources management, and provides a method and device for reviewing cultivated land occupation and compensation space. The method includes: acquiring a plurality of layers to be superimposed, and the layers to be superimposed include vertex coordinate information; according to the vertex coordinate information , to obtain the layer to be superimposed with the largest area among the layers to be superimposed; spatially superimpose the layer to be superimposed with the largest area and the occupied layer, and obtain the area of ​​the overlapping part of the layer and the corresponding cultivated land quality level; superimpose according to the preset The rule is to spatially superimpose the remaining unsuperimposed layers to be superimposed and the occupied layers, and obtain the area of ​​the overlapped part of the layers and the corresponding cultivated land quality grade; the obtained area of ​​the overlapped part of the layers And the corresponding cultivated land quality grade is matched with the supplementary layer, and the audit information including the matching result is output. Accurate calculation of the spatial area of ​​the superimposed part of various layer data by the above method can improve the review efficiency and accuracy.

A laminate flooring colorized solid sealing wax comprises, by weight, 50-85% of paraffin, 10-45% of a polymer material, 1-8% of an organic pigment, and 1-8% of a surface modifier. A preparation method of the laminate flooring colorized solid sealing wax comprises the following steps: weighing required raw materials according to above proportions, fuse-mixing the raw materials, and cooling. Lock catches of wood floors processed with the laminate flooring colorized solid sealing wax have moisture-proof lubrication effects of the lock catches of the floors processed with traditional paraffin, and the colorized solid sealing wax is configured according to the color of the floor surface to unify the floor in color to effectively cover base materials at the lock catches of the floors, so a uniform color effect is obtained, and the overall aesthetic degree of the floor is greatly improved.

The embodiment of the invention discloses an HTTP-based information filtering and superimposing method and device. The method includes: removing HTTP redundant information in the first downstream TCP packet carrying the HTTP packet, the HTTP redundant information being unnecessary information for browser browsing in the HTTP packet; The remaining carrying space of the TCP packet after the redundant information; if the size of the remaining carrying space is not less than the size of the target content, then put the target content into the remaining carrying space to obtain the processed TCP packet , and send the processed TCP packet to the downlink port. The device is used to implement the method. The HTTP-based information filtering and overlay method disclosed in the embodiment of the present invention can enable network link devices to realize the overlay of HTTP packets at the minimum cost.
