Abstract: Disclosed in the present invention is a cell culture method, including the following steps: first loading a one-step container body (1) into a microenvironment; adding a cell culture solution to the one-step container body (1); and successively adding a supplementary fluid to the one-step container body (1) as the culture time increases. The one-step container body (1) has at least two inner side surfaces with different areas. The inner side surfaces with the different areas form corresponding culture surfaces (2) for culturing cell solutions with different volumes. The cell solutions are first borne on a small-area culture surface (2) to be cultured. As the volumes of the cell solutions increase, the cell solution is borne on the large-area culture surface (2) to be cultured. Further disclosed is a cell culture container, including a one-step container body (1).

Abstract: A method for preparing a semi-rigid melamine foam plastic, comprising Step (1): adding a formaldehyde solution and polyvinyl alcohol (PVA) to a reactor, heating the reactor, and adding alkali; Step (2): feeding solid melamine powder and a modifier 3-aminopropyltriethoxysilane (APTES) into the reactor, raising the temperature in the reactor to 75-85° C., adjusting the pH value of the solution of material by adding acid; heating the solution of material, performing a heat preservation reaction, and then adding alkali, Step (3): feeding a predetermined amount of foaming agent, emulsifier, auxiliary agent and curing agent into a stirring reactor to obtain a mixed auxiliary agent; pumping the mixed auxiliary agent and the semi-rigid modified melamine resin into an emulsifier; placing the emulsified resin into a microwave heating chamber for microwave foaming; Step (4): cutting the semi-rigid melamine foam plastic obtained in step (3) and then drying.

Abstract: Disclosed is a drying-wetting separated filling method and a filling apparatus for an electrowetting display device. The filling method comprises filling a non-polar solution into pixel grids on a lower substrate of an electrowetting display device in air, and filling a polar solution to immediately cover the non-polar solution filled after filling the non-polar solution into the pixel grids. Compared with filling the non-polar solution into the polar solution, directly filling the non-polar solution in air has better filling uniformity, easier operation and control. With the method, the fillings of the polar solution and the non-polar solution are easy, having a higher filling efficiency, and no air bubble residue.

Abstract: Embodiments of the present application disclose an optical axis adjusting mechanism and a camera. The optical axis adjusting mechanism includes a first adjusting plate (2) and a second adjusting plate (3), wherein the first adjusting plate (2) and the second adjusting plate (3) are located outside the imaging unit housing (4). In embodiments of the present application, the first adjusting plate and the second adjusting plate are provided for adjusting a direction of an optical axis of an optical device provided in an imaging unit housing, and the first adjusting plate and the second adjusting plate are located outside the imaging unit housing, so that it is more convenient to installation and adjustment.

Abstract: Described is a memory searching system, including an indexing module and a searching module. The indexing module, provided with multiple indexed databases, acquires and records updated indexed data in an indexed database provided to the indexing module and synchronizes the searching module with the updated indexed data recorded in the indexed database provided to the indexing module. The searching module updates an indexed database in a memory with the updated indexed data received from the indexing module (the indexed database in the memory corresponds to the indexed database provided to the indexing module), and switches a pointer of the indexed database to the updated indexed database in the memory. Also described is a memory searching method, a real-time searching system and method, capable of better supporting real-time search and of updating indexed data in seconds in a realistic application, reducing the cost of hardware equipment and improving searching efficiency.
