Abstract: Provided herein is a potassium-binding polymer prepared by polymerization reaction of a monomer and a crosslinking agent, wherein the monomer is the compound of formula (V), the crosslinking agent is the compound of formula (VI), and/or the compound of formula (VII), wherein the variables are as defined in the specification; to the use thereof for treating or preventing hyperkalemia.

Abstract: A screw compressor slide valve with gas pulsation attenuation function includes valve walls and internal through holes. A screw compressor includes the screw compressor slide valve. A part of exhausted gas of the screw compressor is directly discharged from an exhaust port to an exhaust chamber to form a main exhaust flow channel; another part of the exhausted gas is discharged from the exhaust port into the exhaust chamber after being delayed by the internal through holes, which forms a branched exhaust flow channel. Since the branched exhaust flow channel is longer than the main exhaust flow channel, when the gas pulsation in the branched exhaust flow channel lags behind that in the main exhaust flow channel by 180-degree in phase, two gas pulsations in the two flow channels are offset due to opposite gas pulsation phases, which attenuates the gas pulsation, thereby suppressing induced vibration and noise.

Abstract: A display module and a display apparatus are provided in the present disclosure. The display module includes a backlight assembly and a display anti-peep assembly. The display anti-peep assembly is on a light-exiting side of the backlight assembly; and the display anti-peep assembly includes a display assembly and an anti-peep assembly; and the anti-peep assembly at least includes a plurality of light-blocking parts which is arranged along a direction in parallel with a plane where the display module is located. The display module further includes a first display mode and a second display mode. In the first display mode, the anti-peep assembly is in an operating state, and a light-exiting angle of the anti-peep assembly is ?1; and in the second display mode, the anti-peep assembly is not in an operating state, and the light-exiting angle of the display anti-peep assembly is ?2, where ?1<?2.
