The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.

结果表明：不同区域环境中重金属呈现不同程度累积，其中以Cu、Ni最为显著，含量由高到低依次为尾矿坝排污沟＞尾矿坝＞废渣堆＞农田土壤；尾矿砂和沉积物中重金属分布以Ni含量显著高于Cu含量为特征；而农田土壤和风化物及降尘中重金属分布以Cu含量高于Ni含量为特征，前者Cu、Ni主要来源于尾矿，后者与冶炼烟尘排放有很大关系；样品中除Cr、Zn以残渣态为主外，Cu、Ni、Pb化学形态分布有较大差异，Cu以可氧化态和残渣态为主，Ni以可还原态为主，其次为弱酸提取态，Pb以可还原态为主，其次为残渣态。

In the probabilistic model for wind farm, the uncertainties of wind speed is takes into account, and the real power injected and reactive power absorbed by the wind turbine are described as the function of the voltage magnitude, the slip of the induction machine and the circuit parameters of the wind turbines. In the unified iteration method, the slip of induction machine is introduced as the new correction value. The Newton-Raphson algorithm is used to solve the unified iteration of state variable and slip. Thus, the proposed method retains the quadratic convergence of the Newton-Raphson algorithm.

该风电概率模型考虑风速的随机性，将风机输出的随机有功功率和吸收的随机无功功率描述为电压幅值、异步机的滑差和风轮机的电路参数的函数；联合迭代方法中，异步风力发电机的滑差作为新的修正量被引入，使用牛顿-拉夫逊方法求解关于潮流状态变量和滑差的联合迭代，加热器因而迭代过程保持了牛顿-拉夫逊方法的平方收敛性。

The result of the calculation indicates that there are a rather sectional rigidities of arch rib , cross beam and radio of width-long ,the dead load of arch will much bigger than the vehicle load and wind load in operation, and the in-plane stability will larger than the out-plane stability and the in-plane stability is the main factor controlling of design.
