The invention belongs to the technical field of computers, and particularly discloses a network resource management method and device, and the method comprises the steps: directly creating a network resource if the same type of network resources exist in all network namespaces when the network resource is created for a certain network namespace; otherwise, creating a global linked list, a mapping table and the network resource; marking the newly created network resource, distributing a first pointer to the newly created network resource according to the resource type of the newly created network resource, and inserting the first pointer into the global linked list; inserting a first pointer and a second pointer pointing to the position of the newly created network resource into the mapping table; wherein when the network resources are accessed by the process, triggering a page error processing program through a first pointer, taking the page error processing program as a unique entrance for accessing the network resources, and responding to the access in combination with the mapping table and the identifier; the identifier is used for verifying whether the network namespace where the current access process is located is matched with the network namespace to which the network resource belongs. According to the invention, isolation and security of network resources are ensured.

The application discloses a kind of local vortex structure quantitative analysis methods for optimizing the performance of biomimetic submersible, belong to underwater biomimetic robot technical field.The method of the present application comprises, first based on the numerical calculation of flow field is carried out based on the immersed boundary method, obtains overall flow field data;Then according to the geometric characteristics and function of biomimetic body Preset division local analysis area;Finally, the contribution of each area to overall hydrodynamic force is calculated using quantitative formula based on vortex dynamics.The method solves the problem that the existing technology has space dimension reduction, grid is not suitable for large deformation motion and cannot complete time-varying analysis, quantifies the contribution of local vortex structure of key parts to water power at each moment, establishes the quantitative space-time mapping relationship between local vortex structure and stress, realizes the quantitative connection from flow field micro mechanism to engineering optimization design, provides accurate and reliable quantitative analysis tool and decision basis for deep understanding of biological propulsion mechanism and implementation of targeted performance optimization of biomimetic submersible.
