Abstract: A method for extracting and correcting a ringing component in a dynamic pressure measurement signal of a shock wave flow field includes: adaptively decomposing a dynamic pressure measurement signal of a shock wave flow field through an empirical mode decomposition (EMD) method, and extracting a ringing component in the dynamic pressure measurement signal of the shock wave flow field; constructing a ringing component distortion correction model through a convolutional neural network (CNN) and a dataset through a staggered spanning dataset construction method; and predicting a time series of a segment with mode mixing in the ringing component, to accurately extract a ringing component in a dynamic pressure response signal. The method combines advantages of an adaptive signal decomposition method and a CNN model identification method.

Abstract: A medical adhesive and the preparation method, and application thereof. The medical adhesive is in the form of a gel, which contains a giant salamander skin mucus and an aqueous solution; the ratio parts by weight of the giant salamander skin dried powder and the aqueous solution is 1:1 to 1:6, and the weight content of the giant salamander skin mucus freeze-dried powder in the medical adhesive ranges from 14.2% to 50%. The present invention also provides the preparation method for preparing the aforementioned medical adhesive, and at the same time, the aforementioned medical adhesive is applied for the wound.

Abstract: This utility model relates to a type of addition agent releasing device used for dental water jet, which is equipped with at least one holding space for releasing addition agents. For example, if the addition agent is toothpaste, each holding space should be equipped with at least one inlet channel entering into the holding space with certain angle, one outlet channel, and without or with at least one water bypass that makes some of the water will not flow into the holding space. The above-mentioned technical solution results in the following technical benefits: 1. The water can spurt into the holding space with addition agent in it at oblique direction and release addition agent evenly; 2. The adjusting device for water flow can adjust flow of the water which flows into the holding space; therefore, it can adjust the time of releasing addition agent; 3. Using addition agent is simple and easy; 4. Small in size, easy to be constructed individually or compounded with other functional parts.
