The invention discloses a terrain LOD generation method. The terrain LOD generation method comprises the steps of: importing remote sensing images and DEM elevation data which are downloaded online oracquired by means of radar aerial photography, point cloud surveying and mapping and the like into Global Mapper or other GIS software; reading the obtained elevation data through gadl, converting the elevation data into grid data, performing grid division on the grid data, converting the divided grid data into a triangular relationship network, storing a relationship structure of triangular vertexes and surfaces, and calculating a vertex secondary error sequence of each block for the divided grid data; then simplifying the data by taking the data as a whole, and generating a quadtree structure; performing secondary organization on results of a plurality of single-time processing data to form a new quadtree structure so as to dynamically schedule each single-time processing data; and rendering the processed data, determining a cutting mode according to a current view frustum, and ensuring smooth rendering of the city-level number in combination with quick search traversal of the quadtree structure.

The present application belongs to the technical field of dishwashers, and in particular relates to a dishwasher and its airtight door assembly. The airtight door assembly includes a door panel, a first transparent panel and a second transparent panel. The bottom of the concave cavity is provided with an observation window, and the edge of the observation window is formed with ribs arranged around the observation window along the height direction of the door panel, and the first transparent plate is covered on the upper end surface of the door panel , and cover the concave cavity, a first sealing layer is provided between the first transparent plate and the rib, the second transparent plate is sealed and connected with the bottom of the door panel, and covers the observation window. In this way, the complete sealing protection of the observation window is realized, which can effectively prevent high-temperature water vapor from infiltrating into the observation window from the gap formed by the assembly of the door panel, the first transparent plate and the second transparent plate, thereby preventing the observation window from being exposed to high-temperature water vapor. Atomization occurs under the action of osmosis, effectively ensuring the observation effect of the observation window.

The invention discloses a dust isolating device for indoor decoration construction, which belongs to the technical field of decoration, and the dust isolating device comprises a dust-proof box, wherein a vacuum cleaner is connected to the side wall of the dust-proof box through a pipeline, an air pressure balance opening is arranged on the top wall of the dust-proof box, a filter cloth is arrangedinside the air pressure balance opening, a plurality of operation openings are arranged on the side wall of the dust-proof box, an operation glove inside the dust-proof box is arranged on each of theoperation openings, a visible glass is arranged above the operation glove inside the dust-proof box, a cleaning device for cleaning the inside wall of the visible glass is arranged on the side wall of the dust-proof box, a transparent dust-proof paint is coated on the inside wall of the visible glass, the dust-proof paint is prepared from the following raw materials in parts by weight: 10 to 30 parts of nanometer antimony-doped tin dioxide; 40 to 60 parts of polyamide resin; and 30 to 45 parts of ethyl acetate. The dust-proof paint has the following beneficial effects: The dust-proof paint has a good antistatic performance, so as to avoid dust adsorption on a visible glass, thereby ensuring the observation effect of the visible glass on the inside of the dust-proof box.

The invention provides a miniaturized fixed star tracking optical system capable of achieving whole-day observation. The whole-day miniaturized fixed star tracking optical system comprises an imaging unit, a band-pass fiber, a main reflector, an auxiliary reflector and a scan reflector and a through hole is formed in the center of the main reflector, wherein the imaging unit, the band-pass fiber, the main reflector, the auxiliary reflector and the scan reflector are sequentially arranged along an optical axis of an imaging optical path; incident light sequentially passes through the scan reflector, the main reflector and the auxiliary reflector, is reflected for three times, and then is emitted to the imaging unit through the central through hole of the main reflector and the band-pass filter; a part of an optical path of the incident light coincides with a part of an imaging optical path in the scanning field from 30 degrees to 50 degrees so that the requirement for miniaturization of the system can be satisfied; the main reflector and the auxiliary reflector are respectively provided with a light shield and the edge of the scan reflector perpendicularly extends so that a light shielding board can be formed. Field scanning is conducted through the scan reflector, a zone between the 30-degree airspace and the 80-degree airspace of the zenith can be observed all day, and an instant field of the system is smaller than 30'.
