The preparation method comprises the following steps: crushing raw materials, carrying out dual-frequency ultrasonic extraction in combination with a solvent to obtain a high-activity and high-oxidation-resistance component, filtering through a micro-filtration membrane, mixing an extracting solution and crushed filter residue raw materials according to a ratio, sterilizing, adding modified microcrystalline cellulose and other auxiliary materials, and mixing, so as to obtain the anti-aging body-consolidating and life-prolonging pill. And refining honey and pelleting to prepare the life-prolonging pill with high stability, good pill quality and high oxidation resistance.

This application provides a method, apparatus, medium, and program product for multi-round fracturing in deep coal reservoirs. It relates to the field of deep coal reservoir stimulation technology. Each round of multi-round fracturing includes hydraulic fracturing and well shut-in. A simulated fracturing scheme for the nth round corresponding to the target deep coal reservoir is obtained. If n is 2, the fracturing fluid system in the simulated fracturing scheme is a variable viscosity slickwater fracturing fluid system; if n is not 2, the fracturing fluid system in the simulated fracturing scheme is a low-concentration guar gum fracturing fluid system. Based on the real-time wellhead pressure, real-time microseismic information obtained in the (n-1)th round, and the fracture network morphology after well shut-in in the (n-1)th round, an unconventional fracture propagation model is used to predict the fracture network morphology corresponding to hydraulic fracturing in the nth round, according to the simulated fracturing scheme of the nth round. Based on the fracture network morphology, real-time wellhead pressure, and real-time microseismic information corresponding to hydraulic fracturing in the nth round, the well shut-in time for the nth round is determined. This aims to achieve balanced stimulation of deep coal reservoirs and improve EUR (Earnings Equivalent to Fluid Regulator).

The utility model discloses a suspended ceiling, relates to the technical field of interior decoration, the suspended ceiling includes: skeleton structure, gypsum board, strengthening net and connecting piece, skeleton structure extends on the surface of building structure, one side face of skeleton structure is used for installing the building structure at building indoor space top, gypsum board is installed on the opposite other side face of skeleton structure, the reinforcing net is connected with the connecting piece, and the connecting piece is connected with the reinforcing net. Mounting holes are formed in the gypsum board; the reinforcing net is arranged on the side, away from the framework structure, of the gypsum board, and the connecting pieces sequentially penetrate through the reinforcing net and the mounting holes and are connected to the framework structure so that the reinforcing net and the gypsum board can be connected to the framework structure. By additionally arranging the reinforcing net, the reinforcing net abuts against one side face of the gypsum board through the connecting piece, the connecting strength of the gypsum board and the framework structure is improved, stress concentration of the screws is dispersed, the stress difference generated between the screw fixing positions and the periphery of the gypsum board due to the fact that the distance between the screws is increased is reduced, and the tensile strength of the gypsum board is improved.

The present invention discloses a bendable support member and a flexible display module, belonging to the field of display technology. The bendable support member includes a metal layer, a first side of the metal layer is provided with a plurality of first grooves, and the plurality of first grooves are interconnected through a first connecting groove; a first adhesive layer is formed on the first side of the metal layer, and the first adhesive layer is partially filled in the first groove and the first connecting groove. By providing a first groove on the metal layer and arranging a first adhesive layer on one side of the metal layer, the stress of the metal layer can be relieved when the bendable support member is bent, thereby reducing the stress difference between the first adhesive layer and the metal layer; moreover, the metal layer and the first adhesive layer restrain each other, and can resist the pulling force of the first adhesive layer to separate, so that the metal layer and the first adhesive layer are difficult to separate, thereby making the bending of the bendable support member more labor-saving and smooth.

The invention relates to the technical field of batteries, in particular to a battery cell and a battery. The battery cell comprises a first pole piece, a second pole piece and a diaphragm positioned between the first pole piece and the second pole piece, wherein the first pole piece comprises a first region and a second region; a plurality of first concave-convex structures which are arranged at intervals are formed on the second region of the first pole piece, first concave parts are formed on one side of the first concave-convex structures in the thickness direction of the first pole piece, and first convex parts are formed on the other side of the first concave-convex structures in the thickness direction of the first pole piece; the height of the first convex part is H1, and H1 is larger than or equal to 2 micrometers and smaller than or equal to 80 micrometers. And a plurality of first concave-convex structures which are arranged at intervals are formed on the second region of the first pole piece, so that the second region of the first pole piece is not easy to bend and wrinkle, and the safety of the battery is improved. Due to the height of the first convex part, the second area of the first pole piece is not easy to bend and wrinkle, and meanwhile, the pole piece is not easy to crush in the process of arranging the first concave-convex structure.
