Abstract: A time series data injection method is provided, including: receiving time series data, where the time series data includes at least one parameter identifying a data source that generates the time series data, an indicator indicating at least one attribute of the data source, and a timestamp indicating a time point when the indicator is generated; storing a first parameter group in a row storage format, where the first parameter group includes the at least one parameter identifying the data source that generates the time series data; and storing a second parameter group in a columnar storage format, where the second parameter group includes the indicator indicating the at least one attribute of the data source and the timestamp. In the method, the time series data is injected in a hybrid row-column storage manner.

Abstract: A high-temperature gas-cooled reactor steam generating system comprises a plurality of nuclear steam supply systems, a high-pressure cylinder (21), a low-pressure cylinder (22), a condenser (23), a condensate pump (24), a low-pressure heater (25), a deaerator (26), a water supply pump (27), and a high-pressure heater (28) which are sequentially connected end to end to form a close steam loop. On one hand, the inherent safety of the reactor is guaranteed and the generating system is simplified with the inherent safety. On the other hand, the scale economy of the steam engine system and other systems of a whole power station is guaranteed through batch copy, a shared auxiliary system and a scale effect.
