The invention discloses a silicon negative electrode active material which sequentially comprises a silicon-based material inner core, a flexible solid electrolyte or gel electrolyte middle layer and a carbon-coated outer layer from inside to outside, the flexible solid electrolyte or gel electrolyte middle layer comprises a conductive agent, and the conductive agent comprises a carbon nanotube. According to the silicon negative electrode active material, the surface of the silicon-based material is coated with the flexible solid-state or gel-state electrolyte, so that the volume change of the negative electrode active material in the charging and discharging process is effectively relieved, the electrolyte is isolated, the stability of the negative electrode active material is improved, and the negative electrode active material has relatively high reversible specific capacity and relatively high specific surface area; and excellent long cycle performance is shown.

The utility model relates to microorganism strain proportioning technical field discloses a kind of experimental devices for microorganism strain proportioning, including jar body, installation position is opened in jar body;Mixed component, mixed component is set in jar body, and mixed component is used to proportion and mix to microorganism strain, and mixed component includes driving motor, movable frame, auger shaft and fixed block, driving motor is fixedly connected with jar body, movable frame is set in jar body, movable frame is drivingly connected with driving motor, auger shaft array is set in jar body, each auger shaft is drivingly connected with driving motor, multiple fluid effects are formed by the cooperation of mixed component internal parts, under the cooperation of multiple fluid effects, avoid in stirring Large amount of foam covers liquid surface to hinder oxygen dissolving, lead to aerobic bacteria growth is limited;Foam layer hinders liquid flow, causes local strain or nutrient concentration difference;Foam occupies reactor space, reduces actual utilization rate and other problems.

The application discloses a data migration method and related device, and a data migration system comprises a data migration unit, the data migration unit comprises a thread manager, at least one data reader and at least one data writer. The thread manager acquires the disk bandwidth of the source cluster, determines the number of threads for executing data migration according to the disk bandwidth, and establishes one or more threads according to the number of threads. The target thread corresponds to a target data reader and a target data writer, the target data reader acquires the target row key from the message queue, acquires the target to-be-migrated data corresponding to the target row key from the source cluster according to the target row key, and sends the target to-be-migrated data to the target data writer, and the target data writer stores the target to-be-migrated data into the target cluster. Therefore, the number of threads is dynamically adjusted according to the disk bandwidth to dynamically adjust the migration speed of data according to the business situation, and the influence of the data migration business on the source cluster business is avoided.
