查询词典 speculum metal

The research is about the reuse of urban sewage for virescence irrigation, and the influence of sewage irrigation on eco-environment such as soil, plant, etc. is studied. Under the condition of field sewage irrigation, the transport and transformation and accumulation mechanism of heavy metals, nutrients and organic pollutants as vaporizable hydroxybenzene etc. in the soil-plant system are analyzed. The heavy metal pollution is evaluated by the comprehensive pollution index. The spatial variability of heavy metals in sewage irrigation area is further understood. The spatial variability of heavy metals and physical and chemical properties of soil are reflected in a more straight way by the theory model of variance function curve based on the geographical information system.

在城市污水回用于绿化灌溉对土壤、植物等生态环境的影响研究中分析了大田条件下污灌对土壤-植物体系中重金属、养分及挥发酚等有机污染物迁移转化及富集机理，对重金属污染进行了综合污染指数评价，进一步了解了污灌区重金属分布的空间异质性，基于地理信息系统提出了变异函数曲线的理论模型，更直观地反映出了重金属元素与土壤理化参数的空间变异特征。

By means of flow field software PHOENICS,the flow field of four-strand T type tundish in a specific steel plant is simulated in this paper and the velocity vector diagram and streamline graph of the hot metal flowing under different settings of the flow control device s are analyzed and compared.

应用流场计算软件PHOENICS对某厂四流T型中间包流场进行了数值模拟，分析比较了不同控流装置下钢液流动的速度矢量图和流线图。
