The invention relates to a triple seal mouth-pressing-type opening and closing bottle cap, which comprises an opening and closing ball with an L-shaped round hole inside, a suction tube, an upper seal body with an open slot, and a lower seal body with a central hole, wherein the components are all arranged in a compacted bottle cap shell provided with an opening at the lower part and an open slot on the top, and the compacted bottle cap shell is sleeved into a bottle mouth to be molded by compression; when the components are arranged into the compacted bottle cap shell, the suction tube inserted into the L-shaped hole of the opening and closing ball penetrates through the open slot of the upper seal body, which is overlapped with the compacted bottle cap shell, so that a formed structure similar to a universal joint rotates flexibly; when the suction tube is pressed to be horizontal from vertical, the other hole of the L-shaped round hole of the opening and closing ball is driven to face downwards and align to the direction of the bottle mouth, and drink in a bottle can be poured out through the suction tube; and the suction tube is reset to be vertical after the drink is poured out completely, so that the body of the opening and closing ball right covers the central hole of the lower seal body and the drink in the bottle is sealed and can not be poured out. The bottle cap disclosed by the invention is easy to open, has a simple structure, an attractive appearance and good tightness and reusability, and is low in cost, a special cap opener is not needed, and claret and other wines are continuously alcoholized with face log to be more delicious.

The invention relates to a PostgreSQL high concurrency streaming big data multidimensional quasi real-time statistic method. According to the technical scheme, the method is characterized in that a recording table increment status table, a statistical function, a function increment status table and an analysis function are established, and the function increment status of the recording table increment status table is initialized; the number obtaining frequency of the analysis function is calculated and recorded as an integer and serves as statistic frequency data, the analysis function works, and substeps are started; a computer outputs a statistic dimension table containing multidimensional quasi real-time statistic data according to the recording statistic data obtained by the statistic function. Due to the method, the hardware input is reduced by at least 100 times, and real-time effectiveness is controlled within one minute.

The invention discloses a restaurant site selection optimization method and device. The method includes: determining the pre-selected address of the restaurant according to the collected restaurant site selection influencing factor data set; model; solving the mathematical model of the location of the restaurant to obtain the optimal location of the restaurant. Transform the restaurant location problem into a mathematical problem, and seek the optimal solution within the range of potential optional pre-selected addresses to obtain the optimal restaurant location. Based on the mathematical model, the subjective judgment can be overcome, and the problem of timeliness can be solved at the same time, and various influencing factors can be fully analyzed, thus improving the scientificity and efficiency of decision-making.

The invention provides a method for preparing amphiprotic starch solution for papermaking, which belongs to the field of fine chemicals for papermaking. The amphiprotic starch solution is added at a papermaking wet end, and has a dry strengthening effect on paper. Starch is used as the basic material, water, sodium hydroxide, sodium hypochlorite or potassium persulfate and cationic etherifying agent are added. The amphiprotic starch solution is obtained after the aqueous solution is heated. The preparation method is fulfilled by the heating reaction of aqueous solution. The amphiprotic starch solution has high concentration, can be diluted by cold water to any concentration and cannot be aged, so the technical problem of starch aging is solved. When in use, the amphiprotic starch solution can be added at the wet end without being heated to gelatinize, the amphiprotic starch solution as dry-strengthening agent for papermaking can notably increase the dry strength indexes of paper, such as burst index and ring crush index, and under the circumstance of the same added amount, the amphiprotic starch solution has a better effect than the like product. The innovation of the invention is that a simple technique for producing the amphiprotic starch solution is provided, the production time is not longer than 2 hours, the aging and retrograding problems of the amphiprotic starch are solved, and the invented amphiprotic starch solution can be directly added at the papermaking wet end without going through the step of gelatinization by heating.

The invention discloses a method for data disaster tolerance playback of computing nodes, including the following processes: a process of setting a disk directory, a process of setting the frequency of checkpoint file backup, a process of data entering a computing node, a process of data being processed by the computing node, and a process of computing The process of data playback when the node is abnormal. A terminal device for disaster recovery and playback of computing node data, comprising a memory, a processor, and a computer program stored in the memory and running on the processor, and the processor implements a computing node when the processor executes the computer program The steps of the method for data disaster recovery playback. A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, implements steps of a method for data disaster recovery playback of a computing node. It not only realizes the high-performance data disaster recovery of computing nodes, but also solves the problem of timeliness in data recovery and playback.

Technologically, the present invention utilizes biological enzyme to liquefy and saccharify starch in buckwheat and corn material and homogenizes in a ultrahigh pressure nano level homogenizer so as to reserve the diet fiber, flavone, protein and other nutrient components in buckwheat and corn while avoiding starch aging, deposition, layering and other problems. By means of adding milk material, bifidobacterium proliferating factor, fruit acid and other fixings, the buckwheat-corn milk beverage has rich nutrients and certain disease preventing health functions. It has the fragrance of buckwheat, corn and milk, good source and sweet taste and may be drunk by all people all the year round.

The invention belongs to the technical field of medicinal plastic containers and particularly relates to a method for increasing the airtightness of a medicinal plastic container. The method includes:adding mixing auxiliaries with the weight being 2-6% of the weight of a polyethylene raw material into the polyethylene raw material, and sufficiently mixing, wherein the polyethylene raw material comprises polyethylene with the molecular weight being 0.1-0.3 million, polyethylene with the molecular weight being 0.05-0.1 million, polyethylene with the molecular weight being 0.3-0.5 million and polyethylene with the modified molecular weight being 3-6 million.
