Abstract: The present disclosure discloses a method and apparatus for detecting security event, and a non-transitory computer-readable storage medium, and relates to the field of big data. The method includes: acquiring a time window, and acquiring log data, wherein the time window is a rolling window in a preset period; matching the log data with a security event model in each time window, so as to generate a matching result set in each time window, wherein the security event model is a model comprising a plurality of rule models for identifying whether the log data has an attack behavior; and generating security event data according to the matching result set, so as to restore an attack process according to the security event data.

Abstract: The present invention discloses a liquid-driven nano-porous actuator and the application thereof, and belongs to the field of nano material actuators. According to the present invention, by changing the content of the liquid in the nano-porous material, the interface between the surface liquid of the nano-porous material and air is exchanged between flat and curved states, so as to change the compressive stress acting on the nano-porous material from the surface tension of the liquid and change the elastic deformation of the nano-porous material, thus driving the nano-porous material to contract and expand in a reversible manner and further realizing driving performance.
