Abstract: The present invention discloses an adaptive damping nonlinear spring-variable damping system and a mobile platform system, with the nonlinear spring-variable damping system applied to the mobile platform. The nonlinear spring-variable damping system is characterized in that the system comprises: an oil cylinder accommodating damping oil; a piston, accommodated in the oil cylinder and movable along the oil cylinder to make the damping oil flow; at least one connecting rod, connected to the piston; at least one spring, whose deformation process is constrained by the connecting rod; and a damping adaptive adjustment device, configured to be able to adaptively change the flow resistance of the damping oil according to the vibration of the mobile platform, so as to control the system damping; wherein, when the mobile platform vibrates, the connecting rod and the spring can subject the piston to a nonlinear spring force.

Abstract: A method for level partition of a point cloud includes: decoding a point cloud bitstream, the point cloud bitstream including geometry information and attribute information of the point cloud; determining a maximum permissible value of a first syntax element in the point cloud bitstream; parsing the point cloud bitstream to determine a value of the first syntax element according to the maximum permissible value; determining, according to the value of the first syntax element, a number of levels of detail (LODs) in a process of decoding the attribute information; and decoding the attribute information according to the number of the LODs and the geometry information, to determine a reconstructed point cloud of the point cloud.

Abstract: The present invention discloses an integrated new technique and apparatus for recycling volatile organic compounds of coating printing. The new technique collects a mixed gas of volatile organic compounds produced in the process of coating and drying of a coating machine with a volatiles collecting hood of coating machine, compresses and lead the mixed gas of volatile organic compounds into a condensation system for condensation; the obtained condensate enters a gas-liquid separator to obtain a coating solvent with high concentration; non-condensable lean gas enters a membrane separation and enrichment system to obtain a mixed gas of high concentration organic compounds after membrane separation and enrichment with a complete set of membrane assembly, and then returns to front of the condensation system to repeat the integrated technique.

Abstract: A system for simultaneously preparing alcohol-free wine and high-alcohol liquor, comprising a primary membrane separation system and a secondary membrane separation system. An inlet of the primary membrane separation system is connected to raw materials, and a permeation side of the primary membrane separation system is connected to an inlet of the secondary membrane separation system; both the primary membrane separation system and the secondary membrane separation system comprise an organic matter preferentially-permeable pervaporation membrane. The method for simultaneously preparing the alcohol-free wine and the high-alcohol liquor comprise the following steps: feeding the wine produced by fermentation into the primary membrane separation system, ethanol and aromatic substances therein permeating the membrane in a vapor form to form a primary permeating fluid with alcohol content of 28-32°, and a primary residual permeating fluid being the alcohol-free wine with alcohol content of less than 0.5°.
