Abstract: A heat dissipation control method for operation resources, an operation control system, and a storage medium include: a resource monitoring module configured to determine, based on pre-set conditions, whether operation resources need to be opened or closed; and a heat dissipation management module configured to determine, based on a spatial position layout of each operation resource under a current running state according to a distance between each operation resource in closed operation resources and opened operation resources if opened, operation resources to be opened, and open the operation resources that need be opened. The heat dissipation management module is further configured to determine, based on the spatial position layout of each operation resource under the current running state according to a distance between the opened operation resources if closed, operation resources to be closed, and close the operation resources that need to be closed.

Abstract: A method for controlling an operation unit, a system for controlling an operation unit, and a computer storage medium are provided. The method includes: determining a relative current value; determining target frequencies corresponding to all currently running operation units, determining the temperatures of all of the currently running operation units, and calculating the sum of current values of all of the currently running operation units based on the target frequencies and the temperatures, wherein the target frequency corresponding to each running operation unit is a series of frequencies with which the operation unit can run; and comparing the calculated sum of the current values with the determined relative current value, and if the sum of the current values is smaller than the relative current value, determining the target frequency corresponding to the sum of the current values as a running frequency to be selected.

Abstract: Provided is a method for controlling operation resources. The method includes: acquiring a maximum frequency supporting running of first operation resources in an apparatus; determining a refrigerated plant quantity corresponding to the maximum frequency according to a pre-determined rule; and determining a second operation resource for a specific quantity, and closing the specific quantity of second operation resources, wherein the specific quantity is the same as the refrigerator quantity. Also provided are an apparatus for controlling operation resources and a computer storage medium.

Abstract: The present invention discloses a serum-free medium for full suspension culture of MDCK cells and a preparation method of the serum-free medium. The serum-free medium for full suspension culture of the MDCK cells comprises basic metabolic nutrients, nucleotide, vitamins, inorganic salts, a shear force protective agent, a cell clustering resisting agent, a pH buffer agent, a pH indicator, an influenza virus proliferation accelerant and other additives. The preparation method of the serum-free medium for the full suspension culture of the MDCK cells comprises the following steps: 1) preparing a mixed solution: dissolving and mixing raw materials; and 2) regulating pH: regulating the pH of the mixed solution to 6.3 to 6.7, and setting a constant volume to obtain the serum-free medium for the full suspension culture of the MDCK cells.
