Abstract: A wearable device and an airbag preparation method. The wearable device includes a watch body, an airbag, and an airbag cover. The airbag is detachably connected to an end of the watch body, so that a coverage area of the airbag for the watch body is small, thereby reserving space for installing another module on the watch body. The airbag includes a first layer structure and a second layer structure that are superposed. The first layer structure has a first cavity, the second layer structure has a second cavity, and the first cavity communicates with the second cavity.

Abstract: The present invention relates to a method for precisely determining protein content in edible fungus, belonging to the technical field of food detection. The method is as follows: determining total nitrogen content in an edible fungus sample by using a Kjeldahl method; additionally taking an equal amount of sample, and washing same with acid and alkali solutions to obtain chitin residues; then determining nitrogen content in the chitin residues by using the Kjeldahl method; subtracting the nitrogen content in the chitin residues from the total nitrogen content in the sample, so as to eliminate the interference of the nitrogen content in chitin; and finally obtaining precise protein content by calculation based on a formula. The present invention provides a method for precisely determining protein content in edible fungus, and provides a method for the precise assessment of the nutrient composition and value of protein in the edible fungus.

Abstract: The present application discloses a vibration table, comprising a magnetic circuit device for generating a magnetic field; a moving coil skeleton, disposed in the magnetic circuit device, moving up and down in the magnetic field and having a placement groove; an adapter, disposed in the placement groove; an excitation coil, radially winding along an outer peripheral wall of the moving coil skeleton and located in the magnetic field generated by the magnetic circuit device; wherein, the moving coil skeleton is provided with a cut-off groove. The vibration table provided in the present application uses a metal beryllium as a material for a moving coil skeleton and an accelerometer adapter. The large specific stiffness of the metal beryllium is used to increase the axial natural frequency of the moving coil skeleton, thereby increasing the effective working frequency range of the vibration table.

Abstract: The present invention provides a method for promoting the growth and preservation quality of Agaricus bisporus, and belongs to the technical field of cultivation and preservation of edible fungi. In the present invention, the methyl jasmonate solution is sprayed onto the surface of Agaricus bisporus at a concentration of 10-200 ?mol/L when the Agaricus bisporus grows to the mushroom bud stage, which can accelerate the growth and development of the Agaricus bisporus, improve the post-harvest preservation quality of the Agaricus bisporus, and prolong the shelf life thereof, then improving the yield and commercial value of the Agaricus bisporus. The present invention provides a new method for increase in both production and income and post-harvest preservation of Agaricus bisporus, can be applied to large-scale industrial production of Agaricus bisporus, and has important economic benefits and application promotion value.
