Abstract: Provided is a positive electrode sheet and a preparation method thereof. The positive electrode sheet includes a current collector and a positive electrode material layer. The positive electrode material layer is coated on the current collector and includes a Prussian blue-type material containing crystal water, a conductive agent, a binder, and a gelatinous non-aqueous electrolyte. The positive electrode material layer has characteristics satisfying 0.1?R2*(M1+M4)/((M2+M3)*R1)?9, wherein the M1 represents a thermogravimetric loss rate of the Prussian blue-type material at 200° C.˜400° C.

Abstract: The present application relates to a light pulse signal processing system. A to-be-measured signal light source generates a to-be-measured signal light pulse, and the to-be-measured signal light pulse is transmitted to a cylindrical lens. The to-be-measured signal light pulse is converted into a to-be-measured signal light pulse having a spatial angle chirp by the cylindrical lens, and is outputted and is incident into a pair of long mirrors at different angles. The to-be-measured signal light pulse incident at different incident angles is delayed by the pair of long mirrors. A cluster of to-be-measured signal light pulses with a corresponding repetition rate is outputted to a beam combining mirror, and is combined with a cluster of reference light pulses by the beam combining mirror. A light signal analysis device analyzes the combined cluster of light pulses.
