    Abstract: The present invention discloses a data transmission method, and a data transmission device, which relates to the field of wireless communication technology to solve the problem of low reliability in audio data transmission. The data transmission method is applied to a first device and comprises: receiving a first data group transmitted by a second device during a first time interval, the first data group comprising a first initial data group and/or a first retransmission data group, wherein the first initial data group comprises one or more first data packets that have not been transmitted by the second device before the first time interval, and the first retransmission data group comprises one or more second data packets comprising at least a portion of one or more data packets transmitted by the second device before the first time interval that were not successfully received by the first device; generating a target mapping table based on a reception status of the first data group and a reception status of the data packets transmitted by the second device before the first time interval, wherein the reception status comprises a failed reception; and transmitting the target mapping table to the second device within the first time interval. In this way, the reliability of the audio data transmission can be improved.

    Abstract: A thermal power generation apparatus comprises a boiler (15) and multiple turbine sets for high, intermediate and lower steam pressure operation. Steam exhausted from the high pressure turbine (HP), and reduced in both pressure and temperature, is returned to a reheater (19) for reheating. The reheated steam is then passed to a intermediate pressure turbine (IP). It is desirable to control the temperature of steam entering the intermediate pressure turbine (IP). The invention provides a system for effecting temperature control of the reheater stream in a thermal power plant. The system includes a reheater conduit (10, 21) adapted to define at least a part of a reheat flow path for steam between an exhaust of a high pressure turbine system (HP) and an inlet of a reheater system (19). The system further includes an indirect water/steam heat exchanger (B) having a heat exchange portion within the reheat flow path and defining a water flow path means adapted to receive and circulate feed water. The feed water may be taken from take off points (A, D) in the primary feed water stream.
