The invention discloses a comprehensive cultivation method of soybeans, which is completed through four measures comprising new type planting, precise fertilization, deep ploughing and piling, and stems returning back to the field. The method provided by the invention can improve quality and yield of the good soybean variety and can improve the function of preserving soil, fertilizer and water of soil and the functions of cold resistance, drought resistance, lodging resistance and plant diseases and insect pests resistance; under the precondition of guaranteeing the high yield of the soybeans, the applying amount of chemical fertilizer is reduced; and the method saves cost and increases yield for farmers and saves energy for our country.

The invention relates to the technical field of concrete, and particularly relates to green environment-friendly light-weight high-strength powder concrete which is prepared from the following raw materials in parts by mass: 550-650 parts of silicate cement, 125-150 parts of silica fume, 90-115 parts of fly ash, 110-130 parts of ore powder, 650-800 parts of shale ceramsite sand, 21-26 parts of high-efficiency water reducing agent and 105-130 parts of water. According to the invention, metal fibers, quartz sand and other high-cost raw materials are eliminated by means of the powder concrete accumulation principle; and the light-weight ultrahigh-strength powder concrete of which the volume weight is 1950kg / m<3> or below is obtained by introducing the high-strength ceramsite sand.

In the method of growing a single crystal by the flux method of a sodium-containing solution, a flux is contained in a reaction vessel composed of yttrium, aluminum, and garnet. Compared with the case of using alumina container or yttrium oxide container, the amount of impurities such as oxygen and silicon can be significantly reduced, and a single crystal with low residual carrier concentration, high electron mobility, and high resistivity can be successfully obtained .

The invention discloses a polyester foam sheet and a semi-continuous preparation method thereof, belonging to the field of polymer foam sheets. The polyester foam sheet and its semi-continuous preparation method of the present invention control the dissolved content of the high-pressure fluid in the polyester sheet, and then perform rapid freezing and air-locking treatment on the material at a specific temperature to suppress the desorption and escape of the high-pressure fluid, and solve the problem The impregnated foamed polyester in the prior art can not realize high-quality foaming or long-distance transportation due to high-pressure fluid escape. Continuous heating and foaming, the weight loss rate is significantly reduced, and the implementability is significantly improved. The invention also discloses the polyester foam sheet prepared by the method. The product has a smooth surface, a thickness of 0.2-3.0mm, a length of not less than 50m, a crystallinity of 20-45%, and a density of 0.1-0.6g. / cm 3 , with a light reflectivity of more than 90%.

The invention relates to a car frame connecting structure comprising a side window longitudinal beam, an upright column, a stiffening beam, a top cap longitudinal beam and a top cap horizontal beam, wherein the side window longitudinal beam is riveted with the upright column through a medium corner; the side window longitudinal beam is riveted with the lower part of the stiffening beam; the upright column is riveted with the stiffening beam; the upper part of the stiffening beam is riveted with the top cap horizontal beam through a large corner; and the top cap longitudinal beam is riveted with the top cap horizontal beam through the medium corner. The car frame connecting structure is made of aluminium alloys or magnesium alloys. The invention achieves the effect on reducing weight approximate to a half under the conditions of same or similar strength of steels by adopting the car frame connecting structure made of the aluminium alloys or the magnesium alloys, thereby greatly reducing the weight of a car body without reducing the strength; and in addition, the invention has the advantages of reduced manufacturing and operating cost, long service life and more energy saving and environmental protection, prevents the stress concentration caused by adopting a welding mode through riveting connection and has firm connection without generating cracks.

This invention relates to a seawater battery-driven water vehicle for sailing in the ocean, including a main body, a flow channel, a seawater battery and a power system. The flow channel is disposed in the main body and includes an inlet, an outlet and a wall. The seawater battery is installed inside the flow channel, and includes the seawater that flows into the flow channel and a cathode and an anode that are connected with the wall respectively and separated from each other while contacted with the seawater. The power system is equipped on the main body and is electrically connected with the seawater battery and contacted with the ocean outside the main body. In this invention, accordingly, an electrochemical reaction respectively with the anode and the cathode in the flow channel is performed in the seawater to generate electric power, and the power system is driven by the electric power to push the main body to move in the ocean, so as to have a stable supply of electricity without reducing the carrying load of vehicle in water.
