Abstract: A battery may include: a battery cell; a housing to accommodate the battery cell, where the housing may include a pressure relief structure to release, out of the housing, emissions induced by thermal runaway of the battery cell; and a charging connector to be electrically connected to the battery cell. The charging connector may include a body portion disposed on a side that is of the housing and that is oriented back from the battery cell, and covers the pressure relief structure. The emissions induced by thermal runaway of the battery cell are able to pass through the pressure relief structure and act on the body portion so that at least a part of the body portion may be triggered to move away from the battery cell to electrically disconnect the charging connector from the battery cell.

Abstract: The present disclosure provides a self-adaptive test method for an intelligent prediction algorithm of analog measured values. Firstly, an event recording sequence, an analog measurement point ID and an analog measurement point alarm value are read from a time sequence event record table, an analog measurement point table and an alarm threshold table. Next, operation records of a normal operation state of a unit within a statistical cycle are acquired to form historical statistics of measured values of the analog measurement point based on switching value signals. Then, simulated measured values of the analog measurement point with time scales are calculated based on the historical statistics, the analog measurement point alarm value and an analog measurement point current measured value. Finally, sensitivity is calculated; and an alarm is sent to remind a technician to adjust the algorithm when the sensitivity is greater than a threshold.

Abstract: Provided by the present disclosure are a nanoemulsion and method for its preparation, and a high-temperature-resistant, high-density, oil-based well completion fluid and the application thereof. The nanoemulsion comprises a lipophilic alkenyl monomer, a hydrophilic alkenyl monomer, an emulsifier, a cross-linking agent, and water. The high-temperature-resistant, high-density, oil-based completion fluid comprises a base oil, a main emulsifier, an auxiliary emulsifier, an aqueous solution of salt, organic soil, an alkalinity regulator, a filtrate loss reducer, a stabilizer, and a weighting material. The stabilizer comprises the described nanoemulsion.

Abstract: An energy storage system includes a housing, a detection component, an air intake fan, and an air exhaust fan. The housing is provided with an air inlet and an air outlet. The detection component is coupled to the housing and is configured to detect a concentration of combustible gas within the housing. The air intake fan and the air exhaust fan are both coupled to the housing. The air intake fan drives external airflow to enter the housing through the air inlet, and the air exhaust fan drives airflow within the housing to exit the housing through the air outlet. Both the air intake fan and the air exhaust fan are configured to start up when the concentration of combustible gas reaches or exceeds a minimum value of a specified range. The energy storage system provided in this application can improve the discharge efficiency of combustible gas.

Abstract: A construction method for a shallow-buried multi-arch tunnel under water-rich geological conditions includes the following steps: cleaning a grouting ground surface; marking a grouting reinforcement scope; performing survey setting-out; drawing a cross-section diagram to scale; calculating out coordinates and angles of anchor points that need to be set; marking drilling positions; nailing small wooden piles at the drilling positions for identifying; determining a setting depth of the anchor rods according to ground elevation; drilling holes, cleaning bottom of hole, grouting, performing construction preparation, performing long pipe shed construction at the entrance after an earth-rock of a tunnel entrance and an open cut tunnel is excavated to flush with a springing line of the tunnel. A down-the-hole drill is used for drilling in construction. Long pipe shed grouting is designed based on solidifying a soil mass in limited scope around a consolidation pipe shed.

Abstract: Disclosed is the use of ALDH1A and an agonist, a catalysate and an inhibitor thereof. In particular, disclosed is the use of ALDH1A or an agonist thereof, or a catalysate thereof in the preparation of a pharmaceutical composition or a formulation for the treatment and/or prevention of autism.

Abstract: A method and system for configuring a multi-mode base station is disclosed so that a network system may specify a radio access mode for the base station. In the present invention, a configuration control unit inside the base station reports resource capabilities of the base station to a configuration decision unit. The configuration decision unit determines a mode for the base station according to network planning and the reported resource capabilities, generates a configuration file for the base station according to the determined mode, and delivers the configuration file to the base station. The configuration control unit configures relevant resources of the base station according to the received configuration file.
