A communication method and apparatus are provided. The method includes: receiving configuration information from a network device, where the configuration information indicates an occasion and/or a period for sending a measurement signal on a second uplink carrier; obtaining signal quality or signal strength on a downlink carrier associated with a first uplink carrier, or signal quality or signal strength on a downlink resource on a first uplink carrier; and when a first condition is met, sending the measurement signal on the second uplink carrier by occupying the occasion and/or the period; or when a first condition is not met, determining not to send the measurement signal on the second uplink carrier by occupying the occasion and/or the period.

Communication method and apparatus

The present application provides a continuous preparation system and method for vinylidene chloride. In the present application, by coupling two stages of high gravity reactors, the product vinylidene chloride and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method, and the product obtained using the method has high purity. In addition, by combining steam stripping and high gravity, trichloroethane and alkali solution are rapidly mixed for mass transfer, and the product vinylidene chloride is rapidly distilled from the reaction system in form of the azeotrope (based on rapid diffusion of water vapor), such that the reaction proceeds continuously towards the direction of producing vinylidene chloride, thus significantly improving the conversion rate. As proved by a test apparatus, the present application can stabilize the purity of the vinylidene chloride product at 98% or more (mass fraction), decrease the TOC value of chloride salt wastewater to 100 mg/L or less, and decrease the consumption of materials and the cost of subsequent salt-containing wastewater treatment.

A system and method for preparing epoxy chloropropane is provided in that by coupling three stages of high gravity reactors, the product epoxy chloropropane and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method. Further, by combining the azeotrope with the multiples stages of high gravity reactors, the gas phase mass transfer and the liquid phase mass transfer of the azeotrope are improved aiming at the features of the azeotrope in the reaction system, thus making the overall conversion rate higher. In addition, by combining steam stripping and high gravity, dichloropropanol and alkali solution are rapidly mixed for mass transfer, and the product epoxy chloropropane is rapidly distilled from the reaction system in the form of the azeotrope, such that the reaction proceeds continuously towards the direction of producing epoxy chloropropane, thus significantly improving the conversion rate.

A reaction apparatus used for a continuous reaction process for the preparation of trifluoroethane includes a housing, a rotary cutting component, a submersible pump and a flow deflector. The flow deflector includes two sets of flow-deflecting plates, each set of said flow-deflecting plates including a plurality of flow-deflecting plates. Two sets of flow-deflecting plates are fixed to each of the two opposing side walls, and the two adjacent flow-deflecting plates are in offset alignment. The submersible pump is arranged inside the reaction chamber body. A liquid inlet line can connect a directly to the submersible pump without requiring the arrangement of an additional pipeline.
