Abstract: The present disclosure is related to terrein functioning as a biopesticide formulation in drought resistance and growth promotion of crops. The formulation containing terrein can be treated by soaking or spraying on the crops. It is especially suitable for drought and water shortage conditions, promoting growth of plant root length, seedling height, fresh weight, and dry weight, greatly increasing crop yield, and significantly improving drought resistance of crop plants. Under the condition of seed soaking treatment with 10 ?g/mL terrein, promotion rates of root length, seedling height, fresh weight, and dry weight of pakchoi are 99.19%, 15.66%, 40.34%, and 49.12%, respectively. The source of terrein is easy to obtain and the cost is low. It has a simple structure and is easily soluble in water. In the actual application process, it only needs to simply prepare an aqueous solution or mix with other pesticide formulations for seed soaking or spraying treatment.

Abstract: This application discloses a battery cabinet. A drain assembly is disposed at the bottom of a cabinet body of the battery cabinet. The drain assembly includes a drain valve. A valve spool and a magnetic object are disposed in the drain valve. The valve spool is movably disposed in the drain valve and has a first state of sealing the drain valve or a second state of opening the drain valve. The magnetic object generates a magnetic force to keep the valve spool in the first state, and the valve spool stays in the second state when a downward force applied to the valve spool is greater than a preset value. Therefore, draining is started when the water accumulated on the valve spool reaches a specified weight, and a new valve spool is automatically closed after the water is drained.

Abstract: The present disclosure relates to the field of microelectronics and solid-state electronics, and in particular to a calibration system and method for weighting errors brought about by parasitic capacitance in split capacitor-based successive approximation analog-to-digital converters. The method uses an MSB array that does not add additional capacitors, only a switch SM to reduce the comparator design difficulty. Meanwhile, an LSB array may add a calibration DAC array CA including a binary array of P-bit unit capacitors, a calibration structure Cfraq, and a ground switch Sk. The calibration structure Cfraq includes four unit capacitors and two switches S1 and S2. By controlling the switches S1 and S2 different capacitance values can be generated to reduce the chip area consumption. This structure can reduce the error to LSB/4 and the weighting error of the ADC, and increases the effective number of bits of the ADC without excessively increasing comparator gain.

Abstract: A method of interfacing a discrete digital workshop information system is provided, where the information system includes mutual integration among product lifecycle management (PLM), enterprise resource planning (ERP), a manufacturing execution system (MES), an energy management system (EMS), and a warehouse management system (WMS) of a finished product. A method of interfacing based on a data dictionary fusing different function datasets is proposed to solve the problems of a current discrete industry information system, such as single in function, a small amount of integrated information, a large number of “information islands” existing, incapable of achieving full-process informatization management and control, difficulty in product quality tracing and the like. By the method, it is possible to realize flexible production in a discrete manufacturing industry, precise management and control of a production process, significant improvement in product quality and significant reduction in operating costs.
