Abstract: In a logging identification method for a small fault based on stress anisotropy and crustal stress types, a magnitude and direction of a current crustal stress are determined by means of logging calculation of the crustal stress, and a transformation location of a crustal stress type is determined; a development location of the small fault is determined according to the transformation location of the crustal stress type; and an included angle between the current crustal stress and the fault is determined according to an amplitude of variation of stress anisotropy. The present disclosure provides the logging identification method for a small fault based on stress anisotropy and crustal stress types. According to the method, prediction cost is low, operability is high, and a prediction result has a reference value for guiding exploration and development of a complex oil and gas reservoir and construction of a gas storage.

Abstract: A gold mine cyanide tailing disposal method is provided. The disposal method performs a harmless decyanation treatment on a cyanide tailing slurry obtained from a mineral processing plant, and then performs a resource treatment where a cyanide tailing slurry is subjected to a thickening to obtain a higher concentration. When a backfill is needed, a paste is produced by adding a cementing material after a homogenized stirring of a two-stage horizontal agitator pumped to an underground mining site for filling by a plunger pump. The cementing material is to solidify an underflow and prevent cyanide from being filtered out. When a backfill is not needed, the paste is directly delivered to an open storage area for storing by the plunger pump.

Abstract: The present invention discloses a fruit wine product beneficial to the health of a cardiovascular system and a preparation method thereof, and belongs to the technical field of traditional food functionalization. The present invention uses the fruit wine as a base material; by leaching black garlic and baked onion and/or adding tomato clear juice powder and concentrated onion juice, taking advantage of the synergistic effect of alcohol with promoted Amadori compounds, flavonoids and/or proanthocyanidins extraction from the black garlic, baked onion, tomato clear juice powder and concentrated onion juice, to prepare fruit wine product containing 5-15 g/100 mL alcohol, 20-100 mg/100 mL Amadori Compound, 30-50 mg/100 mL total flavonoids and/or 100-250 mg/100 mL proanthocyanidins, and such fruit wine product can more effectively reduce the blood viscosity of consumers and achieve an beneficial effect on cardiovascular health.

Abstract: The present invention relates to a method for preparing an iodine-doped TiO2 nano-catalyst and use of the catalyst in heterogeneously catalyzing configuration transformation of trans-carotenoids. The iodine-doped TiO2 nano-catalyst is prepared by a sol-gel process using a titanate ester as a precursor and an iodine-containing compound as a dopant in the presence of a diluent, inhibitor and complexing agent. The catalyst exhibits high activity for isomerization of the trans-carotenoids into their cis-isomers within a short catalytic time. The catalyst can be easily prepared and is highly efficient, economical, recyclable and environmentally friendly.
