First, the conception of wet compression is defined. A calculation method of moist air and wet gas thermodynamics properties is set up, which treat them as real gas and can give out the results of any water-air/gas ratio. Second, the thesis build the simulation model of water injection between compressor stages of a single shaft gas turbine, based on which the stable analysis is processed and the characteristics of key performance parameters are given out, such as the variation of air flow, pressure ratio, turbine inlet temperature with the water quantities. Results showed that enhancement of power output is outstanding.

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340~1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230~2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ~20and the lake returned to high level during 2330~930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.
