The invention relates to a three-dimensional vegetable planting device and a planting method thereof. The three-dimensional vegetable planting device comprises planting bags and a planting frame. Each planting bag is made from nylon net, and in the shape of a cylinder, a cone or a hollow cylinder, planting belts made from non-woven fabrics are uniformly arranged at the outer layer of each planting bag, the planting belts and the outer layer form sowing grooves, a hollow cylinder body is arranged in the center in the inner layer of each planting bag, a shading cover is arranged on the upper portion of the hollow cylinder body, a spray nozzle is arranged in the middle portion of the shading cover, a hook is arranged to the top, and a water absorbing layer is arranged in the bottom of the hollow cylinder body. A vegetable planting matrix is injected between the outer layer of each planting bag and the inner layer of each planting bag, and a hard base is arranged under the matrix and provided with soil humidity sensors. The hollow cylinder body is an inverted cone, and the bottom is open. The planting bags are hanged to the planting frame through hooks in order. By adopting the three-dimensional vegetable planting device and the planting method thereof, the number of vegetables in unit area can be raised, and the vegetables can well absorb sunlight to carry out photosynthesis and are in ventilation because the vegetables are hanged in the air.

The present invention discloses an energy substitution type self-power generation airplane of using the electricity to substitute for the fuel oil. The energy substitution type self-power generation airplane is characterized in that an uninterrupted power supply (UPS) is installed on an airplane body, a commercial power charger, a super capacitor, a battery pack, an AC-DC rectifier, a DC-AC inverter and a static bypass switch are connected according to a circuit mode to form the UPS, and the UPS is also in parallel connection with a Laval power system; the Laval power system is formed by installing a plurality of gas turbine generator sets in at least one Laval pipe, the Laval pipe is formed by connecting a contracted pipe (1), a throat pipe (2) and an expanding pipe (3) in series, and thegas turbine generator sets (4) are installed at the expanding pipe (3) having the maximum speed in the Laval pipe. The energy substitution type self-power generation airplane of the present inventionis a technology of generating the power based on the relative airflow of the Laval pipe for the airplane, different flow velocities generate the power, the efficiency is high, the power is large, theloading capacity is strong, and the great dreams of the people of using the electricity to substitute for the fuel oil are realized.

A device for a sweeping vehicle wiper to apply a force to the ground. The device comprises a connection plate (2) movably connected to a wiper assembly (1) of a sweeping vehicle, and the other end of the connection plate (2) is hinge-connected to a brush disk support (3). The brush disk support (3) is provided with a torsion spring (4), and the force-applying end of the torsion spring (4) applies a downward pressure to the connection plate (2). The device uses a light wiper assembly to meet the pressure requirement specified in the industry, thereby saving the manufacturing material. By means of a structure that the torsion spring applies a downward pressure, the space for mounting the tension spring may be greatly reduced, so that the structure is still applicable when the gap between the wiper assembly and the brush disk assembly is small, and therefore, the present invention has higher adaptability.

The invention belongs to the field of inorganic luminescent materials. A method for inhibiting a concentration quenching effect in Yb/Er:NaGdF4 up-conversion luminescent nanocrystals comprises the following steps successively: adding gadolinium acetate, erbium acetate, magnesium acetate, ytterbium acetate, oleic acid and octadecene into a three-necked bottle to obtain an anhydrous transparent solution A; after naturally cooling the solution A to 30 DEG C, adding a methanol solution of sodium hydroxide and ammonium fluoride into the solution A drop by drop; after all of the methanol solution is volatilized, rising the temperature and carrying out heat preservation, and then naturally cooling to room temperature; and washing nanocrystals with a mixed solution of ethanol and cyclohexane, and drying the washed nanocrystals to obtain a final product. The method has the advantages of being simple, low in cost and high in yield.

The invention discloses a production technology of bright steel wire. The bright steel wire uses carbon-steel alloy steel as a raw material of steel wire production. The finished steel wire is prepared by the following technology steps: step 1, performing a pickling and phosphatization treatment for the raw material to obtain the pre-treated wire materials; step 2, multi-pass drawing the pre-treated wire materials in the step 1 to obtain semi-finished wire materials; step 3, putting the semi-finished wire materials in the step 2 for washing and cleaning, and then boronizing; step 4, drawing the product obtained in the step 3, and then performing stress annealing in a bright annealing furnace; and step 5, treating the semi-finished wire material obtained in the step 4 with antirust oil, and packaging to obtain the finish product. The production technology solves problems existing in prior art; and the bright steel wire prepared by the production technology is high in brightness, strong in antirust capability. The production technology is strong in practicality and suitable for wide use.

The invention discloses an efficient deodorant with a surface absorption function. A stock liquid mainly comprises the following components in percentage by weight: 10-60% of a cationic surface active agent, 10-60% of hydrogen peroxide, 10-75% of alcohol, 1-10% of essence and the balance of harmonic water. The medicament is mixed to obtain the deodorant stock liquid. The medicament is good in deodorizing effect, wide in use object, low in using environmental requirement, long in storage time (the expiration date can reach 1 year), wide in sterilizing and algae removing range, strong in volatility, less in residue, convenient to clean, self-volatile, free from toxicity and harm, convenient and environment-friendly and strong in lasting deodorizing capacity, and characteristics of various materials are effectively combined, so that the purpose of low cost and high efficiency is realized.

The invention discloses an epoxy organosilicone high-temperature resistant coating material, prepared from the following components by weight: 70 to 80 parts of epoxy organosilicone resin, 30 to 40 parts of polyphthalamide resin, 10 to 20 parts of aluminum paste, 0.3 to 0.7 part of dispersant, 5 to 7 parts of wollastonite powder, 4 to 6 parts of zinc phosphate, 6 to 8 parts of talcum powder, a proper amount of auxiliary and the balance of a proper amount of water. According to the adopted technical scheme, the epoxy organosilicone resin and the polyphthalamide resin are taken as main components of the resin system coating material, and are filled and mixed with the added wollastonite powder, zinc phosphate, talcum powder and aluminum paste, the adhesion property of the high-temperature resistant coating material is enhanced, and the coating material can be widely applied.
