Abstract: The present invention relates to the technical field of computers, and more particularly, to a method for generating training data based on immunohistochemistry, and a storage device. The method for generating the training data based on immunohistochemistry includes the following steps: performing immunohistochemical staining on a target object through different antibodies; labeling the target object according to staining results; and generating training data according to labeling results. According to the method, a pathologist can label a tissue or cell of interest rapidly and conveniently without performing labeling through H&E slicing in combination with histomorphology. In addition, since this tissue or cell is labeled based on an immunohistochemistry technology of a gold standard, this labeling is more accurate compared with manual labeling performed through H&E slicing in combination with histomorphology.

Abstract: Iodonium salt initiator and processing-free thermally sensitive plate precursor containing thereof, and processing-free thermally sensitive plate and use thereof, At least one of two para positions of two benzene rings of the iodonium salt initiator is an alkene group containing a carbon or nitrogen or oxygen atom and a double bond at an end. The alkene group can increase a steric hindrance of the iodonium salt, improves compatibility of the iodonium salt, the thermosensitive resin and the crosslinkable prepolymer, reduces the surface migration of the iodonium salt in the imaging layer and improves the initiation efficiency. During the laser imaging, a double bond contained in a residual end of the iodonium salt can perform a crosslinking reaction with the thermosensitive resin and the crosslinkable prepolymer, and thus reduces damage to the imaging layer caused by small molecules.

Abstract: A downhole power generation device and a separate-zone waterflooding device, which relate to the field of oil and gas development technologies. The downhole power generation device comprises a housing extended axially and a rotating wheel, a striking mechanism and a piezoelectric bimorph provided in the housing. The piezoelectric bimorph is axially extended and circumferentially distributed around an axis of the housing, with one end of the piezoelectric bimorph being fixed. The rotating wheel is in transmission connection with the striking mechanism and can be rotated by fluid to drive the striking mechanism to rotate. The striking mechanism can touch the other end of the piezoelectric bimorph during rotation so that the piezoelectric bimorph vibrates back and forth.

The present device can collect the energy for waterflooding so as to provide stable and continuous electric energy, thereby prolonging or even avoiding the replacement of the downhole power supply equipment.

Abstract: Disclosed is a pressure/flow rate control valve comprising a pressure-adjusting section having a valve plug for reducing the pressure of a pressure fluid flowing through a clearance between a hole and itself, a stem which is displaceable integrally with the valve plug and which is installed with a packing, and a spring member which is fastened to one end of the stem, for pressing the valve plug toward an annular projection formed on an inner wall surface of a first valve body.

Abstract: A lift amount of a valve plug is controlled with respect to a period of time from valve-closing operation instruction time for an electric opening/closing valve to arrival at a preset quick valve-closing operation position at which a flow line of a fluid discharged from a discharge port of a nozzle is in a constricted state, in accordance with a driving action of an electric actuator. The valve plug of the electric opening/closing valve is controlled to be at a closed position after the arrival at the quick valve-closing operation position. Accordingly, it is possible to prevent the incontinent liquid drip from the nozzle during the valve-closing operation of the electric opening/closing valve.
