This invention discloses a method for improving the stability of flavonoids in formulated wines. It involves treating the wine with an aminocarboxylic acid chelating resin to effectively remove aluminum, iron, and copper elements, reducing the interaction between these metals and the flavonoids, thereby enhancing the stability of the flavonoids in the formulated wine.

This utility model relates to the field of lithium battery technology, and proposes a soldering structure and a cylindrical lithium-ion battery. The soldering structure includes multiple parallel and spaced solder lines, and the solder lines are wavy in shape. The width W1 of the soldering structure is 1.6-3.4 mm; the minimum distance W10 between two adjacent solder lines is 0.6-1.1 mm. By controlling the reasonable size of the soldering, problems such as welding explosions and discoloration of solder lines caused by heat concentration due to excessively small soldering can be avoided. At the same time, excessively large soldering can prevent the increase in laser travel, the reduction in welding efficiency and production capacity, and the decrease in welding reliability caused by the expansion of the solder line area, thereby effectively improving welding quality and efficiency.

The application discloses a pet urine pad, and relates to the field of pet products.The pet urine pad comprises a urine pad body, a color developing test paper sheet and a cotton swab.The urine pad body is provided with a groove, and the urine of a pet can flow downwards to the inner bottom surface of the groove and contact the color developing test paper sheet at the bottom.The color developing test paper sheet can develop color after contacting the urine, so as to reflect the health status of the pet.The different shapes of the color developing test paper sheet can be used to detect different health indexes, so that the health status of the pet can be more comprehensively and intuitively reflected.Further, the cotton swab is arranged on the inner side surface of the groove.In the case that the urine volume is small, the cotton swab can absorb the urine and flow to the inner bottom surface of the groove to react with the color developing test paper sheet.The cotton swab can also filter the colored urine or dust and other interference substances, so as to prevent the color change of the color developing test paper sheet.

The application discloses a video processing method, device and equipment and a computer readable storage medium, and applies to the field of video processing, and comprises the following steps: receiving a code stream output by an encoder; if a saturation enhancement enabling flag in the code stream is valid, determining whether a pixel belongs to a skin color protection area according to a preset condition in a linear light domain; if the pixel belongs to the skin color protection area, performing smoothing interpolation processing on a saturation scaling factor in metadata parameters by using a sliding window according to a relative position of a hue angle of the pixel in a skin color interval to obtain an effective enhancement coefficient; if the pixel does not belong to the skin color protection area, taking the saturation scaling factor as the effective enhancement coefficient; and obtaining an enhanced color component according to a color difference component of the pixel and the effective enhancement coefficient and a luminance value of the pixel. The application solves the problems of insufficient saturation, over-saturation of the skin color area, skin color distortion and other video quality problems of an HDR video after dynamic range conversion.
