According to archaeological investigation and preliminary excavation, the Yangjia Site, located in the northern Taihu Lake region, at Wuxi City, jiangsu Province, is a Neolithic archaeological site dominated by cultural remains attributed to the late Majiabang Culture(6270–5920 cal. a BP). Here a systematic archaeobotanical study was conducted to investigate vegetation landscape, environmental characteristics and rice agriculture in the prehistoric northern Taihu Lake area. The abundance, frequency and standard density of charred rice were the highest of all of the remains of the seed plants unearthed. In addition, a variety of wetland weeds, such as Haloragaceae, Cyperaceae, Carex sp., and Oxalis corniculata, were found. Pollen and phytoliths recorded that the evergreen-deciduous broadleaf mixed forest(represented by Quercus and Castanopsis) tends to decrease, while Poaceae was the most significant of the terrestrial herbs, water area expanded and water activities strengthened, indicating generally warm and humid conditions at the Yangjia Site during the late Majiabang Culture. All indicators of pollen, phytolith and macro-plant remains suggest that wild rice should be once distributed at or around the site before human occupation, after which rice agriculture progressed rapidly during the late Majiabang Culture.

目的:套筒式调节阀内空化的发生不仅会增加整个管路系统的能量损耗,而且会造成阀体及管路的失效破坏。本文旨在探讨四种不同形状的阀芯对套筒式调节阀内不同阀芯位移工况下的空化流动及空化强度的影响,为套筒式调节阀的优化设计及空化控制提出建议。创新点:1.根据四种不同形状的阀芯,研究套筒式调节阀内阀芯形状对流动及空化特性的影响;2.建立数值模型,对套筒式调节阀在不同阀芯形状和不同阀芯位移条件下进行流动及空化分析。方法:1.建立带有不同形状阀芯的套筒式调节阀数值计算模型,并比较分析阀芯形状对阀内速度、压力及空化情况的影响(图4,8和11);2.建立不同阀芯位移条件下的阀门数值模型,比较分析阀芯位移对阀内速度、压力及空化情况的影响(图6和10);3.建立不同形状阀芯及不同阀芯位移下的阀门模型,分析阀芯形状和位移对阀内流动及空化特性的综合影响(图7和13)。结论:1.在四种不同形状阀芯的条件下,高速流动区域和空化发生区主要位于套筒与阀芯之间的间隙;2.在直筒形和椭球形阀芯条件下的阀内空化强度明显强于平底形和圆台形阀芯条件下的空化强度,因此平底形和圆台形阀芯在空化控制方面具有更好的效果;3.在四种不同形状阀芯的条件下,随着阀芯位移的增加,阀内由空化产生的蒸汽总体积先增加后减少。
