Abstract: A polymer ultrafiltration membrane with a bicontinuous highly interconnected porous structure, a preparation method and applications thereof are provided. The ultrafiltration membrane has a bottom layer and a polymer layer. The polymer layer is divided into a sublayer and a surface layer. The surface layer is of a uniform small pore structure with a narrow pore size distribution. The sublayer is of a bicontinuous highly interconnected three-dimensional network porous structure. The bicontinuous highly interconnected porous structure of the bicontinuous highly interconnected porous ultrafiltration membrane is characterized as follows: in the thickness direction of the sublayer, the cross-sectional porosity on any XY cross-section perpendicular to the thickness direction is 40-90%, preferably 60-90%, and further preferably 70-90%; and the difference in the cross-sectional porosities between any two XY cross-sections does not exceed 10%, preferably not exceed 8%, and also preferably not exceed 5%.

Abstract: An objective of the present disclosure is to provide a method and apparatus for scheduling resources in a cloud system. The method according to the present disclosure comprises steps of: determining, according to stability of computing resources in the cloud system, respective resource priority levels of the respective computing resources; determining a scheduling algorithm corresponding to a current job when it is needed to schedule the resources; and allocating the resources based on the scheduling algorithm and resource priority levels of currently available respective computing resources. Compared with the prior art, the present disclosure has the following advantages: by differentiating the priorities of the computing resources and supporting a plurality of scheduling algorithms, resource scheduling is performed based on a variety of scheduling algorithms and resource priorities, which enhances the flexibility of resource scheduling and enhances the resource utilization and system throughput.
