The invention discloses a production method for granular function-intensifying type magnesium-containing ammonium phosphate. The method comprises the following steps: taking ammonium phosphate which is 5%-50% of the total amount of the phosphoric acid required by the production and adding magnesium oxide for reacting; introducing the acquired product into liquid ammonia and neutralizing, thereby acquiring reaction slurry containing magnesium ammonium phosphate and ammonium phosphate; producing ammonium phosphate grains by utilizing the remaining 95-50% of phosphoric acid according to an original process; sending the reaction slurry to the tail part of a pelletizer; spraying and coating on the surfaces of the ammonium phosphate grains; and drying, screening and cooling, thereby acquiring the magnesium-containing ammonium phosphate product. According to the invention, the important medium element magnesium is added into the traditional ammonium phosphate product; magnesium and phosphorus have an important synergistic effect; the absorption of crops for phosphorus can be obviously promoted; the fertilizer efficiency and the use ratio of the phosphatic fertilizer can be promoted; the crop quality can be promoted; according to the method, the ammonium phosphate product can be effectively prevented from moisture absorption, decomposition and re-crystallization; the functions of resisting against dust and blocking of similar packaging oil can be achieved; a certain slow release effect can be achieved; the process according to the invention is simple, practical and efficient; the product quality is high; the economic returns are excellent; the environment is protected; the application prospect is excellent.

The invention discloses a method for remarkably improving the critical current density of a Bi2212 superconducting material.

The invention discloses an electromagnetic suspension driving device which comprises a starting device, a driving small disc, a driven large disc and a load, wherein the driving small disc is provided with a small disc magnetic block, the driving small disc and the starting device are connected through a driving shaft, and the driven large disc is provided with a large disc magnetic block and connected with the load through a driven shaft. An upper magnetic suspension ring and a lower magnetic suspension ring with repellent magnetic polarity are fixedly arranged below the driven large disc. When the electromagnetic suspension driving device works, the driving small disc is driven to rotate at a high speed by the starting device, the driven large disc in a suspension state is pushed to rotate, and then the load is driven to generate power which is several times as much as the input of the starting device. The invention has the advantages of large energy efficiency, low investment and operation cost, no pollution, no limitation by natural environmental conditions and the like, and completely conforms to a power device with environment protection, high efficiency and energy saving.

The invention provides a statistical data compression method and system based on standard deviation, and the method comprises the steps: 1, judging the upper limit value of the number of statistical units to obtain a total statistical unit; 2, according to a preset sampling rate, screening out statistical units meeting a preset condition from the total quantity statistical units; 3, calculating an index average value and a standard deviation of the statistical units meeting a preset condition, and obtaining index upper and lower limit thresholds according to the index average value and the standard deviation; 4, filtering the statistical units according to the upper and lower limit threshold values of the indexes, filtering out all the statistical units of which the indexes are greater than or equal to the lower limit threshold value of the indexes and the indexes are less than or equal to the upper limit threshold value of the indexes, and aggregating the filtered statistical units to lower dimensions. Statistical memory occupation is controlled by controlling the upper limit value of the statistical unit, and the situation that memory allocation of the statistical unit is uncontrollable due to continuous input of data in a flow test statistical scene is avoided.
