The invention discloses a method for producing ammonium sulphate grain products by using an organic caking agent, which comprises the steps of: (1) selecting one or mixture of polyacrylamide, polyethyleneglycol, and polyvinyl alcohol as the organic caking agent for producing large ammonium sulphate grains; (2) crushing the ammonium sulphate crystals; (3) dissolving the organic caking agent and conveying the liquid into a pelletizer through a pump, spraying the liquid together with steams or water onto the surface of the powder ammonium sulphate for pelleting and obtaining the semi-finished products; (4) drying the semi-finished products; and (5) screening the dried finished products according to the moisture indexes and granularity requirements, and finally selecting the grains with propergranularity as the product and packaging after the dried finished products are inspected to be qualified. The method for producing ammonium sulphate grain products by using the organic caking agent has the advantages that: (1) the technique is simple and the operation is convenient; (2) the caking agent is easy to be obtained and the weight percentage of the product nutrition is above 90 percent,the granularity is uniform and the strength is suitable for large mechanized operation; and (3) the organic caking agent is free to be mixed according to the granulating requirement, and can meet large mechanized production. The method for producing ammonium sulphate grain products by using the organic caking agent is suitable to be popularized and used in producing compound fertilizers.

The invention discloses a wool top rewashing method, a wool oil filling system and a wool top rewashing machine, which belong to the field of fabric weaving. The method comprises the following steps: 1) after the wool top is washed and dried, the wool top is evenly sprayed onto the surface of the wool top; 2) the wool top sprayed with the wool oil is formed into a ball, and stored until the oil and water penetrate evenly and meet the requirements. The oil content and resurgence indicators. The wool oil filling system uses a high-pressure atomizing nozzle to atomize the oil and water into tiny droplets with a micron particle size, which are evenly sprayed onto the surface of the processed wool top at a certain angle. Compared with the prior art, the wool top rewashing method, wool oil filling system and wool top rewashing machine of the present invention can effectively improve the rewashing efficiency and reduce the sewage treatment pressure, and have good popularization and application value.

The invention discloses a method for simulating a terrain humidity index based on a vector network. First a DEM is used to generate a vector network of regular triangular planes, and then a triangulation network TFN algorithm is used to obtain the water accumulation amount from the vector network; a novel algorithm is used to obtain the slope direction and slope from the vector network, and finally the unit catchment area SCA obtained by calculating the water accumulation amount and the slope direction is combined with the slope to simulate the terrain humidity index. Not only is the novel slope direction and slope calculation method provided, but also the method is combined with a TFN algorithm to obtain the novel terrain moisture index simulation method, which improves the simulation accuracy of the terrain humidity index, ensures the reasonable distribution of soil moisture, and meets the accuracy requirements in practical applications.

The invention provides a data processing method for forecasting heavy precipitation weather. The data processing method for forecasting the heavy precipitation weather comprises the steps that firstly, thermodynamic factors, dynamic factors and a moisture index influencing occurrence of heavy precipitation are collected; secondly, according to the precipitation occurrence and development nonlinear theory, the thermodynamic factors, the dynamic factors and the moisture index are integrated, so that the physical quantity index THP is obtained; finally, according to the synoptic situations at 500hPa and at 700hPa of upper air, whether a good lifting mechanism exists or not is judged, and then the belt of the heavy precipitation and the magnitude of the heavy precipitation can be forecasted, wherein the area with a large value of the index THP is the large-probability area of precipitation in next six hours, the maximum value of the THP corresponds to the maximum amount of precipitation in next six hours, when the value of the THP is increased along with time, the amount of precipitation is increased, and otherwise the amount of precipitation is reduced. By the adoption of the data processing method for forecasting heavy precipitation weather, the belt of heavy precipitation and the development and change of precipitation can be more objectively forecasted, the magnitude of precipitation can be estimated quantitatively, and automatic operation can be achieved through a computer.
