The beneficial effect of the invention is that the calculation of the fatigue life is accurate, and the disclosure of the method can avoid repeated research and development, which is beneficial to saving resources and promoting social progress.

The invention relates to the technical field of buildings, in particular to a roof structure. The roof structure comprises side columns, a frame body and a gravity transmission mechanism; the frame body is arranged on the side columns; the gravity transmission mechanism is used for transmitting the gravity of the frame body to the side columns; and one end of the gravity transmission mechanism is connected with the frame body, and the other end of the gravity transmission mechanism is connected with the side columns. Compared with the prior art, the technical problem that an indoor use space is reduced due to the fact that a stand column needs to be arranged in the middle of the bottom face of a roof structure in the prior art is effectively solved, namely, the stand column in the middle of the bottom face of the roof structure is omitted, and in addition, the strength of the whole frame body is improved.

The invention discloses a color vision correcting lens, color vision correcting equipment and a manufacturing method of the color vision correcting lens. The color vision correcting lens comprises a lens body, wherein an all-dielectric multilayer membrane pack with a selective spectrum transmission cutting-off feature is deposited on the front side of the lens body, a visible-band broadband antireflection multilayer membrane pack is deposited at the back of the lens body, the transmission of the band of 545-555 nanometers is not larger than 1%, the transmission of the band of 435-450 nanometers is 15-25%, and the transmission of the band of 640-655 nanometers is 25-35%. The color vision correcting lens has the advantages that appropriate high-refraction-index and low-refraction-index membrane design is selected, transmission is allowed to be cut off at specific bands while rest visible bands can transmit without obstruction, all environment representation information, brightness information and rich color information are obtained, the color vision abnormality of target groups is weakened greatly, and the quality and satisfaction of learning, work and life of the target groups are increased; the color vision correcting lens is compact in structure, simple to manufacture, low in cost and convenient in large-scale production.

A bio-enzyme consists of pectinase, protease, lipase, cellulose, catalase and amylase; the application of bio-enzyme catalysis in residual sludge treatment is that: the residual sludge is treated by utilizing the high-efficiency biocatalysis of the bio-enzyme, odor molecules in the sludge are decomposed and deodorized through enzyme technology, pathogenic bacteria, ova and larvae are killed by utilizing an acid environment formed by inorganic acid generated by the sludge and a high temperature environment in the fermentation process, heavy metal ions in the sludge are stabilized by utilizing the chelation of the bio-enzyme, and the sludge is catalyzed by the enzyme, so that the sludge and water are quickly separated, a large amount of supernate is discharged, the sludge volume is reduced,and the sludge in inland river is reduced and is subjected to innocent treatment; meanwhile, through the bio-enzyme catalysis, long-chain molecules in the sludge are converted into short-chain molecules, polysaccharide and cellulose are converted into protein and amino acid, nutritional components of organic fertilizers are remained, the fertilizer efficiency is improved and the fermentation period can be shortened.

The invention relates to a greening soilless lawn for roof surface, a production method and a using method thereof. The greening soilless lawn consists of a main body of the soilless lawn, a root-proof layer, a humidity sensor, branch pipes, a trunk pipe, a shut-off valve and a main controller, wherein, the root-proof layer is arranged on a roof floor plate in a floor side wall, the main body of the soilless lawn is paved on the root-proof layer, the trunk pipe is connected with the branch pipes, at least one humidity sensor is arranged in the main body of the soilless lawn, the humidity sensor is connected with the main controller through an information control line, the trunk pipe is connected with a water source controller, the water source controller is connected with a water source which needs to supply, and the main body of the soilless lawn consists of a protection layer, a plant layer, a plant growth base layer, a pipeline layer, a nutrition water retention layer and a bottom protection layer. The greening soilless lawn has the advantages of scientific design, reasonable structure, convenient construction, low cost, post maintenance and management, significant ecological effect of purifying urban air, abilities of increasing the area of green land and improving the urban landscape, and the effects of absorbing floating dust, absorbing carbon dioxide, reducing noise, storing water, releasing oxygen and the like.

The invention relates to a safety life-saving chamber which has an up-top and down-bottom inverted and forward '' figure-eight'' slope and a machine body which together form a fit channel type relation. Thick protruding edges protruding from the up, down, left and right at the middle of a chamber body, together with left upper ''['', left lower ''['', right upper '']'' and right lower '']'' channel type fasteners, form the fit relation. The front and the back of each chamber arranged along a longitudinal line form a plane anti-rotating relation. A concave folding plane edge strip at the bottom of the chamber can be used for positioning and loading a concave folding table edge of the machine body. An upper lining plate, a lower lining plate, four hollow screw rods for penetrating the chamber top and bottom and screws and three butterfly-shaped shelves together are used to build the chamber a life-saving device with good integrity and impact resistance. Parachute rods of a parachute are fastened on an annular handle at the chamber top. Foam plastic partition boards are arranged among the various chamber tops for preventing the parachutes at the various chamber tops from winding, and big and small conical springs are arranged at the chamber bottom, so that the safety life-saving chamber can not only prevent the imbalance of gravity generated during the up-and-down tilts and the left-and-right tilts during the flight of a plane, but also realize the automatic rapid escape, parachute opening and soft landing in emergency; furthermore, the safety life-saving chamber can separate the chamber and the parachute when falling into the sea and use a sealing cover with a vent pipe for inputting oxygen into the chamber.
