查询词典 residual

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。

The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.

According to the characteristics presented by armed helicopters during cruising or searching for ground targets, this paper has established the mean-square deviation stationary random model of helicopter tracks. It is an important method to decorrelate the measure noise by estimating the parameters of the color noise online. Kalman filtering and forecasting have been made with helicopter tracks. The simulated study has been carried out on helicopter tracks under the condition of color noise. It is very difficult to get an accurate and reliable prediction when the data is very limited. The paper make use of the theory of grey system to resolve the problem of prediction of helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of n degree, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision.
