Abstract: The invention provides an Auricularia auricula polysaccharide, its application and preparation method thereof, which belong to the technical field of improving polysaccharide. After being degreased, the Auricularia auricula is subjected to preliminary enzymolysis under the effect of helicase, is further subjected to deep enzymolysis under the effect of complex enzyme through synergetic ultrasound-assisted degradation and extraction with H2O2, and is subjected to mixed fermentation by Lactobacillus bulgaricus, Streptococcus thermophilus and Bifidobacterium longum, the obtained fermented Auricularia auricula polysaccharide is subjected to a phosphorylation reaction under the effect of a phosphorylation reagent, and after further deproteinization and decolorization, the obtained fermented Auricularia auricula polysaccharide is chelated with zinc salt to obtain a polysaccharide-zinc compound, and the amount of the extracted Auricularia auricula polysaccharide is improved.

Abstract: A computer system for implementing a financial commodity price analysis. This addresses the issue by real-time collection of microsecond-level transaction data for financial commodities, calculating the maximum weighted price for any period, and converting quantitative data into charts to display the most densely traded prices, trends, and price support and breakout points that stimulate changes in investor sentiment. The system accurately analyzes financial commodity price trends, serving as a reference for investors and a standard for bulk commodity price trading. The financial commodity price analysis system of this invention provides price analysis services based on big data, allowing for a more accurate assessment of market demand and competitive dynamics, thereby formulating more reasonable pricing strategies. The price suggestion generation module can flexibly adjust price suggestions based on different market positioning and cost considerations.

Abstract: A method for predicting a financial product price based on an accumulation distribution indicator includes the following steps: step S1: inputting, by a user, a ticker symbol; step S2: calculating, by a system, an accumulation distribution indicator value based on daily trade data; step S3: calculating an accumulation distribution interval and an average candlestick; step S4: determining whether the accumulation distribution indicator breaks through the accumulation distribution interval upward or downward; if the accumulation distribution indicator breaks through the accumulation distribution interval upward or downward, going to step S6, otherwise, going to step S5; step S5: displaying a chart with the average candlestick; and step S6: displaying a breakout mark, where the breakout mark is a rising mark if an upward breakout occurs or is a falling mark if a downward breakout occurs, and displaying the chart with the average candlestick.

Abstract: A computer-implemented method for calculating a trade price reference indicator includes step 101: creating a frequency distribution chart based on a price increment; step 102: selecting an accumulation distribution point from the frequency distribution chart; and step 103: calculating an average deviation of an active range based on the accumulation distribution point, calculating a significant range, and using the significant range as an equitable value of a market. The method calculates and generates a trading reference price indicator of a financial market product by superimposing discrete quantitative elements of time and quantity distributions onto conventional price-time, so as to accurately reflect real-time market transactions, avoid price manipulation, and achieve accurate statistics and analysis of financial prices.

Abstract: A plasma air sterilizer includes a fan assembly, a plasma generator, a plasma generator channel, and a grounded metal isolation mesh, where the fan assembly is a drum-type fan with side air intake which generates uniform air stream to a flat channel and outputs the uniform air stream to the plasma generator channel; the plasma generator channel has a flat structure and is connected to the plasma generator; the plasma generator generates plasma to sterilize air; and the grounded metal isolation mesh is arranged at an outlet of the plasma generator channel. The air sterilizer has a flat structure, so as to facilitate the arrangement of the sterilizer on wall panels, roofs, and the like without occupying extra space. Moreover, a circulating plasma sterilization mode enables the continuous sterilization of indoor air, is not limited to local sterilization, and shows a prominent sterilization effect.

Abstract: A method for producing a purified Auricularia auricula Polysaccharide (AP) extract of Auricularia auricula (AA). A hydrated predetermined amount of AA is filtered and extracted, producing a first pre-extract. A plurality of additional hydrated predetermined amounts of AA is separately filtered and extracted to produce a plurality of additional pre-extracts. The pre-extracts are combined to form a first extract. The first extract is concentrated and suspended, forming a precipitate. The precipitate is purified to form a first filtrate, and repurified to form a second filtrate. The first and second filtrates are combined to form a first combined filtrate, which is concentrated, purified and dried to form a concentrated extract. The concentrated extract is purified to form a third filtrate, and repurified to form a fourth filtrate.
