The present invention relates to a target-oriented seismic acquisition method and apparatus, a medium and a device. The target-oriented seismic acquisition method comprises the steps of: giving parameters of an initial velocity model and a three-dimensional seismic layout aiming to an underground target position; conducting wave field continuation and focusing analysis on the three-dimensional seismic layout, and calculating distribution of seismic energy on the ground in an underground target region; conducting normalization processing on distribution of the seismic energy on the ground, and then conducting level partitioning to obtain a primary energy region and a secondary energy region; adding the number of shot points in the primary energy region to achieve target-oriented acquisition, and obtaining a target-oriented inhomogeneous laying acquired data imaging result. By using the method of the present invention, automatic feedback adjustment on excitation and receiving sites and parameters thereof is achieved.

The present invention relates to temperature control for refrigerators, which automatically adjusts the on-temp/off-temp values in view of the fluctuation of the ambient temperature. The present invention also relates to a refrigerator on which a sensor of simplified circuit design is reasonably allocated. In accordance with the present invention, ambient temperature is divided into a plurality of particular temperature divisions, the on-temp and off-temp values preferred for refrigerator operation in each corresponding temperature division are determined by experiments. By means of a temperature sensor, on-temp/off-temp values appropriately corresponding to a particular temperature division are applied to keep the temperature of the refrigerator at a required level.
