Abstract: This application provides a buffer allocation method and a device. The method includes determining, by a device, a first output rate of a first queue on the device and a second output rate of a second queue on the device. The method also includes separately allocating, by the device, a first buffer to the first queue and a second buffer to the second queue based on a ratio of the first output rate to the second output rate. The device separately allocates a buffer to each of queues based on a ratio of output rates of the queues, so that a ratio of output traffic of the queues meets an expected scheduling ratio.

Abstract: The disclosure relates to a high molecular weight polyphenylene sulfide resin and a preparation method and application thereof. The disclosure uses a sulfur-containing compound and a halogenated aromatic compound as raw materials, an alkaline compound and a fatty acid as polycondensation aids to carry out a polycondensation reaction. After purification treatment, a primary polyphenylene sulfide is obtained. Then, the primary polyphenylene sulfide reacts with a chain extender at a high temperature to form a high molecular weight polyphenylene sulfide resin. The preparation method of the disclosure has the advantages of high yield, low cost, and is capable of selectively and controllably preparing polyphenylene sulfide resins with different melt viscosities and molecular weights, and the obtained polyphenylene sulfide resins have excellent heat resistance.

Abstract: The present application relates to a method for extracting coenzyme Q10 and a phospholipid from a coenzyme Q10 fermentation bacterium powder. The method is characterized in that the fermentation bacterium powder of a coenzyme Q10 production strain is subjected to extraction with a mixed solvent of which the three-dimensional Hansen solubility parameter is between 21 and 23 (J/cm3)1/2 and the hydrogen bonding solubility parameter thereof is between 10 and 12 (J/cm3)1/2. The present invention can efficiently extract two products, namely coenzyme Q10 and a phospholipid, from the coenzyme Q10 fermentation bacterium powder; the process thereof is highly operable, easy to be industrialized, and can provide a product with high purity and yield, having great economic benefit.
