Abstract: The present invention provides a hydrophobic and hydrophilic composite filler-based rotating packed bed and system. A hydrophobic filler and a hydrophilic filler are formed into a composite filler. When said filler cuts liquid, the hydrophobic filler can sufficiently disperse the liquid so as to make the dispersion of the liquid in the filler zone more uniform, and the wettability of the hydrophilic filler allows the liquid to spread sufficiently so as to increase the wetting fraction of said filler. Different mixing effects can be achieved by means of reasonable combination. Due to the limited number of hydrophilic filler layers and hydrophobic filler layers in said composite filler, the phenomenon of droplet aggregation caused by liquid in a single hydrophobic filler zone and the phenomenon of liquid turbulence reduction caused by liquid in a single hydrophilic filler zone can be avoided. The negative effects of hydrophilicity can be alleviated or offset by means of hydrophobicity, and the negative effects of hydrophobicity can be alleviated or offset by means of hydrophilicity. Therefore, applying a hydrophilic and hydrophobic composite filler to a rotating packed bed can further improve the mass transfer and mixing performance thereof.

Abstract: Disclosed in embodiments of the present application are a data transmission latency compensation method, a terminal device, and TRPs. Each of multiple TRPs providing services for a UE determines a first latency between itself and the UE and obtains the latency difference between the first latency and a reference latency; each TRP performs, according to the latency difference, phase rotation compensation in the frequency domain on first downlink data to be sent to the UE to obtain second downlink data, and sends the second downlink data to the UE. Because the latency of a signal in the time domain is equivalent to the phase change of the signal in the frequency domain, the downlink data of individual TRPs is received by the UE at different moments, but phase rotation compensation is performed on each downlink data in the frequency domain according to the corresponding latency difference, so it can be equivalently understood that in the frequency domain, the UE receives the downlink data sent by all TRPs at the same time, so as to eliminate the influence due to the asynchronization in the time domain of the downlink data sent by individual TRPs arriving at the same UE, so that each downlink data received by the UE does not involve frequency selection in the frequency domain.
