Abstract: The present disclosure provides a system and a method for measuring hot-spot temperature of a transformer, wherein the measurement system comprises a processor, an oscilloscope and a plurality of ultrasonic sensors, wherein the ultrasonic sensors are oppositely arranged on an outer wall of a transformer oil tank and electrically connected with the oscilloscope, and the oscilloscope is electrically connected with the processor; the ultrasonic sensors receive signals transmitted by the oppositely arranged ultrasonic sensors and transmit them to the oscilloscope. The method, by applying an ultrasonic wave to measure the hot-spot temperature of a transformer in real time, solves the problems that methods in the prior art are susceptible to the external environment, have short service life and cannot correctly measure the internal temperature of the transformer.

Abstract: Disclosed in the present invention is an aluminum plated steel sheet, comprising a substrate and a plating layer on the surface of the substrate. The microstructure of the plating layer comprises a Mg2Si phase and an AlMgSiFe phase; and an average grain diameter of the Mg2Si phase is 0.001-5 ?m.

Abstract: A method for text generation, relates to a field of natural language processing, including: obtaining corpus data; labeling the corpus data to obtain a first constraint element; obtaining a first generation target; and generating a first text matching the first generation target by inputting the corpus data and the first constraint element into a generation model.

Abstract: Disclosed are a power supply parallel control circuit, a method and a device. The circuit includes a power switching module, a first switch module, a second switch module, a third switch module and a fourth switch module all connected to the power switching module. The power switching module outputs a first switching signal according to a received switching control signal and control the second switch module to conduct unidirectionally. The first power supply continuously supplies power to a load and the third switch module is controlled to be on. The fourth switch module maintains unidirectional conduction and the second power supply starts to supply power to the load. The power switching module further outputs a second switching signal after a preset time to turn off the first switch module, the first power supply stops powering the load, and the fourth switch module is turned on.

For example, this document provides methods and materials for administering a composition comprising a Ganoderma lucidum extract to a mammal identified as having or as being at risk of having cardiovascular disease. This document also provides methods and materials for slowing the progression of an age-related, acquired, or congenital cardiac dysfunction also are provided.

Abstract: The disclosure belongs to the field of semiconductor photoreceptors, in particular to a near-infrared-visible light adjustable image sensor. By adding a transfer transistor, the disclosure integrates a silicon-based photoelectric diode and a silicon germanium-based photoelectric diode on the same chip to realize that the silicon-based photoelectric diode and a silicon germanium-based photoelectric diode are controlled by the same readout circuit at different time, thus widening the spectrum response scope of the photoreceptor, realizing high integration and multifunction of the chip and reducing the manufacturing cost of the chip. The disclosure is applicable for intermediate and high-end products with low power consumption and photoreceptors for specific wave bands, in particular to military, communicative and other special fields.
