This invention provides a method and apparatus for detecting the reuse of centrifuge tubes in ultra-high-speed centrifuges, comprising the following steps: S1, pressurizing and filling a medium into a new centrifuge tube, and detecting the diameter deformation of the centrifuge tube online; S2, using the maximum pressure that the centrifuge tube can withstand to return to its initial diameter as the yield limit pressure value; S3, replacing the centrifuge tube to be reused, pressurizing and filling the centrifuge tube to be reused with a medium, controlling the reuse pressure value at 75%~95% of the yield limit pressure value; S4, detecting the diameter deformation of the centrifuge tube to be reused online; S5, selecting the centrifuge tube that can return to its initial diameter as the reuse centrifuge tube. This invention can detect centrifuge tubes and determine whether they can be safely reused, significantly reducing experimental costs. It can be used to detect whether replacement centrifuge tubes meet the application requirements of ultra-high-speed centrifuges. It prevents substandard centrifuge tubes from entering the ultra-high-speed centrifuge, causing equipment damage or even sample leakage.

The present application relates to the technical field of glass production, and provides a mixing method for improving the temperature of glass production mixture, which is applied to a mixer with a stirring cavity and comprises the following steps: S1, starting the mixer to sequentially perform dry mixing and wet mixing on glass raw materials; S2, when entering the wet mixing stage, a steam supply unit is opened, so that high-temperature steam starts to be introduced into the stirring cavity of the mixer; and during the whole duration of the wet mixing stage, the steam supply unit is kept in an opened state; S3, when the wet mixing stage reaches a preset duration of the system, the steam supply unit is closed, and the introduction of high-temperature steam is stopped; and when the wet mixing stage ends, the temperature of the material is improved from an initial value to not less than a preset target temperature, thereby effectively solving the problem that the mixing temperature is substandard in a low-temperature environment. The present application also provides a mixing system for realizing the method, which can significantly improve the mixing uniformity and reaction activity, and has the advantages of precise temperature control, energy saving and high efficiency.

The application provides a question and answer method and system based on a large language model, which comprises the following steps: determining a current question of a user and a natural language understanding prompt word; inputting the current question and the natural language understanding prompt word into a pre-trained large language model to obtain a question understanding result and a question to be answered output by the large language model according to a natural language understanding strategy; in the case that the question understanding result is a factual question, retrieving an answer from a knowledge graph based on semantic analysis; inputting the retrieved answer and an answer verification prompt word into the pre-trained large language model to obtain an answer verification result; in the case that the verification is reasonable, taking the retrieved answer as the final answer to the current question; and in the case that the verification is unreasonable, generating an answer by the large language model. In the multi-round question and answer task, the application can deeply understand the question of the user based on the context, effectively retrieve and integrate information from different knowledge sources, and thus accurately and efficiently provide an answer to the current question.
