Abstract: The present invention discloses a strength training bridge, comprising: a plurality of module units, wherein each module unit comprises a base; two adjacent module units are arranged along a length direction of the base and are fixedly connected and/or rotatably connected, so that bases of the two module units jointly form an arched structure with a bottom surface protruding downwards. The bridge forms an arched base protruding downwards, wherein the arched structure has seesaw-like instability, and can be used to perform balance training thereon, or the difficulty of related training is increased or targeted training is performed by controlling balance or generating unbalance in the conventional training, so that the training effect is improved. This bridge has a simple overall structure, rich functions and an attractive appearance, which meets the needs of a user for targeted strength training and is especially suitable for strength training of pectoral muscles and arms.

Abstract: A method for preparing a filling material includes: dissolving FeCl3·6H2O and an imprinted molecule in water to form a reaction solution; adding DMF to the reaction solution and stirring for dissolution; adding BDC to the reaction solution and stirring for dissolution; soaking PC into the reaction solution and stirring; and treating the reaction solution by a hydrothermal method to remove a molecule of an additive decomposition product and prepare the filling material imprinted with a casting structure of the molecule of additive decomposition product. The present invention can effectively and selectively adsorb the additive decomposition products and achieve the effects of effectively removing the additive decomposition products, preventing the decomposition products from being mixed in an electrodeposition film of the copper, realizing the uniform distribution of current on the cathode and the anode, improving the quality and preparing an electrolytic copper foil for high-frequency signal transmission.

Abstract: A space-saving lengthwise and widthwise movable panel system capable of being fully opened belongs to the field of smart building technology and includes a lengthwise panel moving compartment, a panel storage space and a panel control module. The movable panel system can be used as a door and/or window system. All of the panels of the system can be entirely stored in the panel storage space and when storing all of the panels entirely in the panel storage space, the panel system is fully open to allow full lengthwise access to a space.
