The invention discloses a retail store product sales predicting method based on collaborative filtering. The sales prediction of unknown products (specifications) in retail stores is worked out based on the collaborative filtering technology according to sales data of known products (specifications) in different retail stores. According to the scheme, the method comprises the steps that firstly, data such as the retail stores, the products (specifications) and the known sales of the products in the retail stores are collected; secondly, sales-grade conversion is carried out on the known sales to obtain the corresponding grading value; thirdly, the retail stores correspond to users, the products correspond to projects, the grade is the sales-grading conversion result obtained in the second step, and unknown grades are estimated according to the collaborative filtering algorithm; fourthly, the sales-grade inverse transformation is carried out on the grade estimation worked out in the third step, and then the sales prediction is obtained. As the improvement, six kinds of sales-grade conversion and the corresponding inverse transformation are provided, and therefore the sales data of different products in the different retail stores have the comparable grading numerical values with the uniformed standard for the collaborative filtering computing. According to the designed predicting method, the enterprise accurate marketing can be achieved, and guidance can be provided for the marketing activity development and estimation of the products in the retail stores.

The invention discloses an improved engine control method controlled by multiple working conditions PID (proportion integration differentiation). The method can utilize different PID controllers under different working conditions to regulate the air-fuel ratio of the engine under a steady state working condition, and each steady state working condition is monitored to make a judgment, and a plurality of PID controllers are mutually matched for control, so that the engine can be matched with a better air-fuel ratio. The method disclosed by the invention has the advantages that a control strategy theory adopting the PID control in automobile electronic control is enriched, and help is provided for improvement of efficiency of the engine and reduction of energy conservation and emission reduction of automobiles.

The invention discloses an organosilicon waterproof dustproof anticorrosion adhesive which comprises a component A and a component B in a weight ratio of 1:1. The component A is composed of the following raw materials in parts by weight: 100 parts of hydroxyl-terminated polydimethylsiloxane, 20-50 parts of dimethyl silicone oil, 10-40 parts of synthetic reinforcing agent and 60-100 parts of diluter. The component B is composed of the following raw materials in parts by weight: 6-20 parts of crosslinking agent, 2.0-5.0 parts of catalyst, 3-15 parts of coupling agent and 120-180 parts of diluter. The invention also discloses a preparation method of the organosilicon waterproof dustproof anticorrosion adhesive and application of the organosilicon waterproof dustproof anticorrosion adhesive in LED (light-emitting diode) lamp bars and display screens. The method can effectively enhance the properties of the organosilicon waterproof dustproof anticorrosion adhesive, and has the advantages of fewer preparation steps and lower cost. After being coated on the surface of the LED lamp bar and display screen, the organosilicon waterproof dustproof anticorrosion adhesive can perform the waterproof dustproof anticorrosion functions, and thus, the working stability and reliability are effectively enhanced.

The invention discloses a product-oriented retail outlet marketing recommendation method. The product-oriented retail outlet marketing recommendation method includes the steps of collecting data including retail outlets, products, the known sale volumes of the products in the retail outlets and the like; carrying out sale volume-score value conversion to obtain corresponding score values; estimating unknown score values with a collaborative filtering algorithm, wherein the retail outlets correspond to users, the products correspond to items, and the score values are the sale volume-score value conversion results in the prior step; carrying out sale volume-score value inverse conversion on the estimated score values calculated in the prior step to obtain forecasted sale volumes; ranking the forecasted sale volumes of the given products in all the retail outlets, and then recommending the retail outlets at the front ranking row to implement product putting and marketing promotion activities. By means of the product-oriented retail outlet marketing recommendation method, an enterprise obtains an effective measure for selecting the retail outlets for the products to carry out accurate putting and promotion marketing, the marketing effect is improved, cost is reduced, and the competitiveness of the enterprise is improved.

The invention mainly relates to the technical field of planting and discloses a special substrate for seedling of celeries. The special substrate is prepared from the following raw materials: straws, sheep manure, pig manure, fallen leaves, saw dust, bagasse, waste vegetable leaves, sericulture leftovers, plant ash, vermiculite, perlite, EM bacteria and prolonium iodide. The special substrate is balanced in nutrition and is favorable for absorption of seeds, so that the celery seeds germinate 2-3 days in advance, the germination rate is 84.7%, and the planting efficiency of the celeries is obviously improved; the straws, the sheep manure, the pig manure, the fallen leaves, the saw dust and the bagasse are smashed and then are transplanted into the EM bacteria for high-temperature fermentation, so that the multiplication of thalli is promoted, and the fermentation time is shortened; the waste vegetable leaves, the sericulture leftovers and the plant ash are added, and then the temperature is lowered for continuous fermentation, so that the accumulation of extracellular metabolites is promoted, the absorption of the seeds is facilitated, embryos are stimulated to grow, and the germinating time of the seeds is shortened.

The invention discloses a closed link transportation device driven by a permanent magnet linear motor, which comprises an even number of chain links which are connected with each other end to end, wherein every two chain links are connected with each other through a connection lock catch, so as to form a closed transportation link; each chain link is fixedly connected with a runner of a linear motor; a plurality of runners are sleeved on one or more stators of the linear motor; a permanent magnet is arranged between each stator and each runner; the polarities of permanent magnets on adjacent runners are opposite; and each chain link is supported through a transportation rail, and can move freely on the transportation rail. According to the invention, a long chain is driven by the double side permanent magnet coreless permanent magnet linear motor, so as to disperse driving power, overcome centralized tension accumulation as well as limitation and adverse effects caused by the centralized tension accumulation when a chain wheel driving manner is adopted, improve the maintainability and the reliability of a product, prolong the service life of the product, and can infinitely extend the length of the link.

The invention relates to a method for reinforcing paraffin, and concretely relates to a method for reinforcing paraffin through micro-nano fibers to solve the problems of low strength, no toughness, complex preparation method, long preparation time and high preparation temperature of present paraffin. The method comprises the following steps: uniformly mixing paraffin, an emulsifier and an emulsification aid, adding water, stirring, adding the micro-nano fibers a suspension of the micro-nano fibers, mixing through a high mixing machine, and drying in a culture dish to obtain a paraffin/micro-nano fiber film. In the invention, the reaction temperature is low to 80-90DEG C, and the energy consumption is less, so water bath heating can be directly used; the micro-nano fibers can be added at room temperature and can be directly stirred, so the operations are simple and are easy to implement; and the reaction is carried out for about 50min, so the consumed is short.
