By applying normal testing methods to two different examination papers in this essay, the author obtains the following results: Paper One tallies with normal distribution, indicating that the paper is more reasonable and objective; Paper Two is in the shape of negative skewness and lepmokurtic distribution, showing that the paper is easier than the required and less reasonable.
本文采用数理统计正态性检验法对两份不同的英语试卷考分进行了正态性检验,结果表明:试卷Ⅰ考分的分布服从正态分布,说明其命题难易适当、较为客观、合理;试卷Ⅱ考分的分布呈负偏态、尖峭峰,说明其命题较容易,且不合理。

Firstly, we normalized the basic voxel by constructing its minimum oriented bounding box. Secondly, we constructed its D2 shape distribution curve, and computed the values of EMD(earth mover's distance) compared with the corresponding curves of the normal cone and cylinder respectively, and the corresponding top diameters. Finally, we compared the top diameters and obtained the parameters by the bounding box.

While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

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。
