double extraction
1.The Application of DEH Digital Electric-hydraulic Governing System on Double-Extraction Turbine Unit
2.Through analysis,the following sugg estions is put forward:to build200MW and125MW class double-extraction s team tur-bines separately in the two power plants,completed with410t/h an d450t/h class circulating fluidized bed combustion(CFBC)boilers,the total evaporation capacity of boilers in two power plants will reach2540t/h.
3.Major conclusions are as follow:1. Extraction and separation of Astragalus polysaccharide (APS)Dynamic analysis on the extraction process of Astragalus polysaccharide (APS) showed that double aqueous extraction at 60 min and 70 min was able to extract most of the APS from Astralagus mongolicus Bge.
4.Calculation of the Extraction Efficiency in Tunneling-regenerated Double-active-region AlGalnP Light-emitting Diodes
5.The newly-increased annual production capacity in 1998 through capital construction projects included: 3.51 million tons of coal mining, 16.9 million kilowatts of power generation by large and medium-sized generators, 47.26 million kilovolt-amperes of power transformer equipment (including 7.79 million kilovolt-amperes of updated power grid in urban and rural areas), 13.78 million tons of oil extraction, and 2.4 billion cubic meters of natural gas. The year 1998 also saw the operation of 900 kilometers of new trunk railways, 596 kilometers of double-track railways, 995 kilometers of electrified railways, 1,478 kilometers of newly constructed express highways, 14.0 million tons of cargo-handling capacity of coastal harbors, 30,000 kilometers of long distance optical-fiber cable and 10,000 kilometers of newly constructed microwave digital telecommunication lines.
