A method for calculating a surface relaxation rate of a shale includes: a relaxation time T distribution curve and a pore throat radius r distribution curve are obtained through experiments; abscissas of the two distribution curves are standardized, and the abscissa of the relaxation time T distribution curve is expanded or shrunk to ensure an abscissa value corresponding to a maximum ordinate value in the transformed relaxation time T distribution curve is same as an abscissa value corresponding to a maximum ordinate value in the pore throat radius r distribution curve; straight lines with a number of N parallel to a y-axis of a combined curve graph including the two distribution curves are drawn and a ρ value corresponding to each straight line is calculated; and ρ value with the number of N are processed to obtain a final surface relaxation rate ρ'.

Techniques for managing a file system involve: receiving an event published by the file system, the event being associated with an operation on an object in the file system; determining a value of a counter corresponding to the event based on execution information of the operation; determining a target action corresponding to the value of the counter based on a trigger strategy associated with the counter, the trigger strategy defining at least one action that can be triggered by the counter; and generating an indication for causing the file system to execute the target action. Accordingly, file system management in finer granularity can be provided.

Techniques for storage management involve: receiving, at a storage server, an access request for target data from a client, wherein the access request occurs in a session between the storage server and the client; determining, based on attribute information of the client, security information of the session, wherein the security information indicates whether the session is subjected to antivirus protection; and executing, based on the security information, an access operation specified by the access request on the target data. Therefore, the performance of the storage server can be improved while the security of the storage server is ensured.

Embodiments of the present foundation for wind turbine generators comprise four structural members: a relatively long central hollow pier, several arm grade beams, a continued grade beam and a continued shear key. The central hollow pier positions in the center of the foundation system, arm grade beams are arranged evenly in radial direction and extend from the pier to the continued grade beam. Continued grade beam is arranged circumferentially in outer periphery and the continued shear key is built below it. Arm grade beams have a varied section with the far end embedding into ground. The top of the continued grade beam matches the top of arm grade beams, while the continued shear key embeds deeper into ground. All structural members are constructed of cast-in-place concrete reinforced with rebars, and all connections are fixed and rigid. The present foundation uses the ground to shape and form the structural members, no formwork, backfilling and compaction is needed.
