摘要： A non-destructive testing method for article moisture content based on radio frequency identification (RFID) includes: S1, an electronic tag is attached to a surface of an article to be tested, and a signal transceiver is arranged above the electronic tag; S2, the signal transceiver sends a radio-frequency signal to the electronic tag and activates the electronic tag, and the signal transceiver simultaneously receives a backscattered signal from the electronic tag; and S3, the signal transceiver sends the backscattered signal to a signal processor. The method utilizes effects of different moisture content on backscattered signals, arranges the electronic tag on the article to be tested, processes the backscattered signal through the signal processor to obtain a processed signal, and transmits the processed signal to a monitor to display real-time moisture content curve of each article to be tested based on its corresponding serial number.

摘要： The present invention discloses a cooling type dry powder fire extinguishing agent and a preparation method and application thereof, which belongs to the technical field of fire control. Through a static mixing technology, an aqueous solution and a solid hydrophobic material are dispersed and mixed efficiently to form a cooling type dry powder fire extinguishing agent. The fire extinguishing agent is a micron solid particle of the aqueous solution wrapped by the hydrophobic material microscopically, and is in a dry powder state macroscopically, which can significantly reduce the electrical conductivity of the fire extinguishing agent. Meanwhile, a field rapid preparation method is adopted, which can realize real-time preparation. The preparation method is simple and efficient. The technology can be used for fighting a battery fire, has significant cooling and anti-reignition effects and can avoid the problem of electrical conduction of a traditional water-based fire extinguishing agent.

摘要： A method for measuring flicker fusion threshold. Set a measurement scheme, including setting N 8-shaped digital frames in a background light area that flickers within a set frequency. Set ten groups of different frequency combinations being applied to the N 8-shaped digital frames. Assign each frequency in each group of the frequency combinations with a stroke of the 8-shaped digital frame. Randomly select, for each of the N 8-shaped digital frames, one from the ten groups of the frequency combinations. Determine the value of each frequency in each group of frequency combinations in the N groups of frequency combinations. Recognize, by the subject, the flickering digits on the N 8-shaped digital frames in the background light area within the set frequency range. Determine the range of the flicker fusion threshold or the final flicker fusion threshold of the subject according to the result that can be seen by the subject.
