The invention discloses a method for folding a cross-shaped square box, and relates to a method for manufacturing a paper utensil. The cross-shaped square box is formed by the combination of an outer box body component and an inner cross-shaped component. The method comprises the following steps: a piece of square paper is taken, and the outer box body component with square inner angles provided with second triangles is manufactured; another piece of paper is taken to manufacture an inner cross-shaped component with a cross-shaped interlayer which is perpendicular to a square bottom surface and arranged on the square bottom surface; the inner cross-shaped component is placed into the outer box body component; the second triangles of the outer box body component are inserted into end head interlayers of the cross-shaped interlayer of the inner cross-shaped component; the midpoint connection line reverse-folding lines of the inner cross-shaped component coincide with the bottom edges of the box, so that the cross-shaped square box is formed. The cross-shaped square box has a unique style, is simple in design and is easy to manufacture.

The invention is mainly applied to science and engineering type mechanical principle teaching of colleges and universities, and belongs to the field in the technical fields of transmission element application and teaching instruments. By combining the characteristics of different transmission elements for serial combination and innovation, the invention designs a multi-transmission-element transmission form and transmission feature comparison platform, which comprises belt transmission, chain transmission, friction wheel transmission, gear transmission, worm rod transmission, spiral transmission, groove wheel transmission and the like. The problems of simple structure, few knowledge point design sides, huge size, heavy weight and ponderous structure the like of the existing teaching aid are solved, the analysis, the display and the explanation are carried out by aiming at main mechanical transmission elements, and the work features of various transmission elements are highlighted through comparison. The comparison platform has the advantages that students can master basic theories, basic knowledge and basic skills of the mechanical principle, and in addition, the students can primarily have the ability of determining the mechanical movement scheme and analyzing and designing the mechanism.

The invention discloses a multi-chamber microsphere with a gradient structure and a preparation method, which mainly involve: using an amphiphilic block copolymer and hydrophilic modified magnetic nanoparticles to connect in a certain proportion; The multi-chamber aggregates are further coated with crystalline hydrophilic molecules to form stable multi-chamber micro-organisms with gradient structure. ball. The multi-chamber system of the present invention has the characteristics of controllable structure size and number of chambers, and the multi-chamber system can be filled with different functional molecules, so as to realize the carrier function with multiple functional drugs / imaging, which is a nano-diagnosis and treatment A new structure has been developed in the field of integration.

The fatigue-resisting health-care food is a powder preparation made up by using calcium pyruvate, high-quality American ginseng, astragalus root, taurine, zinc glucontate, vitamin C and excipient starch. The tests show that its effect is unique, and it has the obvious functions of invigorating energy vigour and removing fatigue.

The invention discloses synthetic leather for a swivel chair. The synthetic leather comprises a bottom layer and surface layers attached to the two sides of the bottom layer. The surface layers comprise the following components of, by weight, 100 parts of PVC resin, 50-60 parts of a plasticizer, 20-30 parts of aramid fibers, 20-30 parts of silk fibers and 5-10 parts of a foaming agent. The bottom layer comprises the following components of, by weight, 100 parts of PVC resin, 30-40 parts of calcium carbonate, 5-10 parts of a stabilizer and 5-10 parts of polytetrafluoroethylene. A preparation method comprises the following steps of (1) preparation of the bottom layer, (2) preparation of the surface layers and (3) hot pressing compounding. According to the synthetic leather, creativity is high, characteristics are distinct, gas permeability and abrasion resistance are improved overall, and thus the bottom layer and the surface layers are not liable to corrosion and division in a high-temperature humid environment.

Overlaying electronic ink over a document. A typical scenario may be where one it would be useful to mark up a document with electronic ink, such as by making handwritten comments, drawings, and the like over the underlying document. In some embodiments, a developer may easily define an inking surface, such as a transparent or opaque window, over a document. The inking surface may act as an input interface such that a user may write onto the inking surface such that is appears that the document itself is being marked up.

An object of the present invention is to provide a polycarbonate resin composition and a molded article excellent in jet blackness, distinctness of image, impact resistance, scratch resistance due to high hardness, flame retardancy, and thermal retention stability. The present invention provides a polycarbonate resin composition and a molded article using the composition. The polycarbonate resin composition contains a polycarbonate resin and a colorant. A structural unit of a hydroxy compound, and the L* value of the polycarbonate resin composition measured by the JIS K7105 reflected light method is 6 or less.

The invention discloses a universal-type flue gas short circuit preventing device for a subway ventilation pavilion. The device comprises a flue gas outlet, a fireproof cloth, at least four first telescopic casing pipes and a cuboid connecting frame which is composed of at least four second telescopic casing pipes, at least four springs and at least four support columns and used for being installed at an exhaust outlet of the ventilation pavilion in a matched mode; one end of each first telescopic casing pipe is fixed to one support column, and the other ends of the first telescopic casing pipes are connected to the flue gas outlet; the fireproof cloth is arranged in a space formed by the first telescopic casing pipes and the cuboid connecting frame and forms a flue gas exhaust channel together with the first telescopic casing pipes, the cuboid connecting frame and the flue gas outlet, and flue gas exhausted out of the exhaust outlet of the ventilation pavilion is induced to be directionally exhausted. The universal-type flue gas short circuit preventing device is reasonable in design and convenient to use and can effectively solve the flue gas short circuit problem that under the fire working condition, fire flue gas exhausted out of the subway ventilation pavilion massively spreads and invades a new subway ventilation pavilion and ground entrances and exits by serving as temporarily and additionally mounted equipment of the subway ventilation pavilion.
