The invention relates to a method for evaluating the ash-packing effect of cigarettes. This evaluation method divides the ash-packing effect evaluation index of cigarettes into ash-holding capacity and ash-packing capacity. The ash-holding capacity evaluation index includes five items: tightness, bending, eversion, crack, and shedding. , respectively assign different weights to static and dynamic; different weights are also set for the five evaluation indicators; refer to the control standard and the ash-holding capacity scoring standard, evaluate the target cigarette sample, and obtain the ash-holding value; evaluation of ash-packing capacity; The index has a crack rate; the product between the ash holding value and the ash packing value is the comprehensive score of the ash packing effect of the cigarette. The higher the score, the better the ash packing effect, and the smaller the ash packing effect, the worse the ash packing effect. The method can fully consider the ash-packing characteristics of cigarettes under static and dynamic conditions, and comprehensively evaluate the ash-packing effect of cigarettes by combining qualitative and quantitative methods, which can more objectively and effectively measure the ash-packing effect of cigarettes. to judge.

According to the invention, the sales credit evaluation coefficient of a store and the purchase credit evaluation coefficient of a purchase user are counted respectively. According to the counted sales credit evaluation coefficient and purchase credit evaluation coefficient, the corresponding store or buyer user is pushed to the user or the store. Therefore, the matching degree of the purchase user and the store is improved. The bidirectional sales and shopping credit of the store and the buyer are increased. The satisfaction degree of the store and the buyer is greatly improved.

The device includes an applicator for irradiating the object, and a detector system that is configured to capture light being emitted from an irradiated region and, based thereon, to generate a detector signal. A processor unit is configured to calculate a value for the property based thereon and, based on the calculated value, to determine a dose for the irradiation.

The invention discloses a data aggregation method, which is suitable for execution in a server, and the server is respectively connected to a message middleware and a data index database. type of topic data, the topic data includes a timestamp and at least one indicator value; temporarily store the topic data in a preset data flow queue, and use a preset filter flow queue to extract topics one by one from the data flow queue Data; aggregate the same topic data of the same computing node according to at least one aggregation period, and calculate the indicator statistics of the computing node in each aggregation period; aggregate the indicator statistics of multiple aggregation periods within the preset index period Summarize and store in the data index library as the data index of the computing node in the preset index period. The invention also discloses a server for executing the method.

This application discloses a method for detecting human FGFR2 Nucleic acid composition, kit and detection method for gene fusion mutation. The nucleic acid composition includes targeting FGFR2 Primers and probes designed for 18 types of fusion mutations in the gene. In addition to the above nucleic acid composition, the kit also includes DNA polymerase, PCR buffer, dNTPs and cations. The application also provides a detection FGFR2 The method of gene fusion mutation first extracts the RNA of the test sample and reverse transcribes it into cDNA, then uses the cDNA as a template to carry out real-time fluorescent PCR reaction with the above kit, and finally judges whether the test sample is negative or positive according to the Ct value. This application can specifically detect at the same time FGFR2 There are 18 kinds of fusion mutations in the gene, the mutation site covers a wide range, the number of detections is reduced, and it has the advantages of high sensitivity, good repeatability, simple operation, fast detection speed, and easy interpretation of the results.
