The utility model discloses a cell resuscitation culture shaking table, which belongs to the technical field of cell resuscitation culture and comprises a box body, a cover plate is rotatably connected onto the box body, a clamping frame is arranged in the box body, a container is clamped in the clamping frame, a shaking device is fixedly connected into the box body, and a rotating device is fixedly connected onto the upper surface of the shaking device. According to the utility model, when the second motor drives the rotating plate to rotate, the rotating block is driven by the movable rod to do constant-speed circular motion in the shaking frame, and in the process, the motion trail of the rotating block is doubly constrained by the first connecting rod and the second connecting rod to form a composite motion trail; the inclined plate periodically deflects along with the linkage effect of the rotating block to drive the clamping frame to form a 15-degree constant inclination angle, and the unique mechanical linkage design enables the culture container to keep a specific inclination angle during rotating motion, so that a stable vortex field is formed in a culture solution, and the mass transfer efficiency of a gas-liquid interface is remarkably improved.

The application relates to the technical field of new energy resource simulation, and discloses a wind resource dynamic downscaling method based on a global stretching grid mode, which introduces grid stretching transformation in an initial global mode framework adopting an original cubic spherical uniform grid, realizes gradual grid encryption of spatial resolution in an arbitrary target region while keeping smoothness and physical consistency in a numerical calculation process, and realizes seamless transition from large-scale driving data to a local high-precision wind resource field while retaining large-scale meteorological information. Meanwhile, the short-time strong gust and extreme wind speed event simulation capability is improved by embedding a theoretical gust wind speed calculation module in the global stretching grid mode. Further, the target global stretching grid mode is used for downscaling processing of wind resources of a target region to be downscaled, so that seamless transition from large scale to a local high-precision wind resource field is realized.
