Abstract: A flat-plate water-heating photovoltaic/thermal module and a production process thereof are disclosed. The flat-plate water-heating photovoltaic/thermal module includes a frame. The lower surface of the frame is provided with a heat preservation back plate. The upper surface of the frame is sequentially laminated with a glass cover plate, a first photovoltaic cell laminating adhesive, a photovoltaic cell slice, a second photovoltaic cell laminating adhesive, a transparent back plate, a third photovoltaic cell laminating adhesive and a heat absorbing component from top to bottom. A heat preservation cavity is formed between the heat preservation back plate and the heat absorption part.

Abstract: The disclosure provides a data refreshing method of a memory, a controller of a memory, and a memory. The method includes that a target refreshing row in a data row of the memory is determined according to a running state of the controller, the target refreshing row including at least one data row; and in response to determining that a first refreshing interval expires and the target refreshing row includes a first reserved row, the first reserved row in the target refreshing row is refreshed. The first reserved row is a data row with data storage duration smaller than preset duration in the memory. The first refreshing interval is a refreshing interval of the first reserved row.

Abstract: The present invention discloses a device and method for measuring a horizontal/vertical permeability of a hydrate reservoir. The device includes a cooling water/saturated methane water tank, a water injection pump, a methane gas tank, a booster pump, an air compressor, a high-pressure gas tank, a back pressure valve, a gas tank, a data acquisition instrument, a constant-temperature water bath and a hydrate reservoir horizontal/vertical permeability measuring apparatus provided in the constant-temperature water bath, where the cooling water/saturated methane water tank is provided with a water circulation inlet and an intake line at an upper part and a water circulation outlet at the bottom; the intake line is provided thereon with an intake control gate valve; the bottom of the cooling water/saturated methane water tank is in communication with the water injection pump.
