This invention discloses a kind of sandwich and compound beamless slab construction of watering prestress concrete and its constructing method. This construction includes beamless slab body, ribs of inner main and dark slabs and ribs of inner secondary dark slabs with cross arranged. The prestess and stress concrete reinforced bars are arranged in the ribs of main and dark slabs, and the stress concrete reinforced bars are laid out in the upper and lower crust of beamless slab body and in the inner secondary dark slabs with cross arranged. The inner space of the body is stuffed with polystyrene foam sandwich boards. In the job site, first, the form board is propped up and the prestress bars are arranged and stretched and drawn; second, the polystyrene foam sandwich boards should be laid out and fastened and the stress bars are arranged; then the concrete is poured and shaped into the construction, which can satisfy the constructing load-bearing requirements like fireproofing, sound insulation, heat insulation, high-intensity and light quality. Such beamless slab can be used in civilian and various industries construction.

A health-care nano-class board with the functions of killing bacteria, releasing negative ions, removing odor and emitting infrared ray is composed of a shaving board as substrate, a composite nano-class decorative film, and a thermosetting adhesive layer between first two layers.

The invention discloses a fructus forsythiae volatile oil medical hydrocolloid dressing that is formed by sticking two layers of materials, one layer of which is base mounting material, and the other layer is composed of the following components in terms of percentage by mass: 0.1%-10% of fructus forsythiae volatile oil, 1%-20% of water-soluble high polymer material, 10%-60% of rubber substrate, 0.01%-0.2% of antioxidant, 1%-9.7% of foaming agent and 0.1%-87.89% of water, wherein the total content of the above components is 100%. The method for preparing the dressing comprises the following steps of: first, adding a proper amount of water in water-soluble high polymer material so as to over-swelling the water-soluble high polymer material, then adding fructus forsythiae volatile oil to form I-phase solution, then adding antioxidant in the rubber substrate and evenly stirring to form II-phase solution, hybrid mixing I-phase solution and II-phase solution, adding foaming agent and rest water, fully stirring, transitively coating on the base mounting material, refrigerating and then unfreezing. The fructus forsythiae volatile oil medical hydrocolloid dressing has exact treatment effect, is safe and reliable, and has obviously economic benefits.

The invention relates to a broadband radial pattern leaky coaxial cable used for subway and a manufacturing method thereof, and the leaky coaxial cable has the double functions of transmission line of information and duplexer. The structure of the leaky coaxial cable consists of an inner conductor, an insulation layer, an outer conductor and a jacket, wherein, the inner conductor is externally covered with the insulation layer which is externally covered with the outer conductor that is externally sheathed with the jacket, and the insulation layer that covers on the surface of the inner conductor adopts nitrogen or carbon dioxide physical foam to form a foamed polyethylene insulation layer; cambered slotted holes are opened on a clutch gold belt of the outer conductor covered outside the insulation layer. The manufacturing method comprises the steps: (1) a spiral wrinkle inner conductor is manufactured by longitudinal covering welding and embossing by using a copper strip; (2) the nitrogen or the carbon dioxide are adopted to be injected into the smelted polyvinyl plastics, and then the physical foamed polyethylene insulation layer is formed on the surface of the inner conductor by extrusion and cladding; (3) the slotted holes broken out by the clutch gold belt of the outer conductor are the cambered slotted holes; (4) the clutch gold belt of the outer conductor is covered on the insulation layer longitudinally, and the surface of the clutch gold belt of the outer conductor is crowded and covered with the jacket.

The invention discloses a small-range electromagnetic eccentric magnetic gear pair with a radial magnetic field, and can be widely applied to the field of transmission of industries such as wind power generation, electric vehicles and ship driving. The magnetic gear pair is characterized by consisting of a stator and a planetary rotor, wherein the stator consists of a stator enclosure 4, a stator core 5 with Z1 coil inserting slots and 2p1 stator windings 6 arranged in the slots; the planetary stator consists of a planetary rotor core 16 and 2p2 rotor permanent magnets 17 distributed on the outer circle of the planetary rotor core 16; pole pair numbers p1 and p2 have a small number difference, and are co-prime; the small-range stator is connected with the planetary rotor through an eccentric input shaft 1 on which a bearing IV15 is sleeved to form an eccentric structure; planetary rotor is driven by the eccentric input shaft 1 to revolve about a rotating shaft; a permanent magnetic field of the planetary rotor is coupled with an electromagnetic field of the stator through a radially eccentric air gap; the rotor permanent magnets 17 drive the planetary rotor under the action of the electromagnetic field of the stator to backwards rotate about own axis; and low-speed rotation is output through an output mechanism 9 and an output shaft 11.
