Finally,using the theory of System Dynamics,we have carried on modeling through the basin geochemical data in virtue of the software. And according to multifracal' s result of elements, adopting sample average value to limitate prewarning of the pollution trend of the heavy metallic elements, we have gained the early warning value and maded comprehensive prewarning illustration.

最后，首次运用系统动力学理论，借助软件通过盆地地球化学数据进行建模，根据元素多重分形结果建立系统动力学环境预警模型，采用样品平均值对重金属元素污染趋势进行模拟预警，求出了各元素的预警值并做综合预警图。

Besides, the physical property of reservoir is influenced by lithologic characteristic and lithogenesis. If only analyze the data in the universal drill core and make statistic average, the method is definitely insufficient to represent the reservoir physical property, thus, particularly in this paper introduces th...

储层物性又受岩性及成岩作用的影响，单从常规岩芯分析数据统计其平均值，不足以代表储层物性特征，文中着重探讨三叠系雷口坡组、嘉陵江组的物性特征及与岩性的关系，分析储层横向变化和影响储层物性变化的因素。

The trajectory of the center of pressure on the transverse plane, and the range of displacement, velocity, and root mean square of the COP on the mediolateral and anteroposterior planes were examined.

Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years).

用U检验对两组测量角度的平均值进行比较，Spearman 相关系数估计年龄因素的影响，用Logistic回归分析第三磨牙的萌出与第一磨牙、第二磨牙的轴倾度、性别和年龄之间的关系。

Also referred to as a normal distribution or normal curve, a bell-shaped curve is a perfect mesokurtic curve where the mean, median, and mode are equal.

指一种完美的常态曲线，平均值、中间值和模型都是平均的。

Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Per-mo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ^34 S values of the ores commonly fall within the accepted mantle range of 0±2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ^34 S value is also within this range.

如1.1 Ga的Duluth杂岩、Noril'sk地区二叠－三叠纪侵入岩和1.4 Ga的Kabanga侵入岩体中矿床的硫同位素测定结果证明硫来自含硫化物和硫酸盐的围岩。1.3 Ga的Voisbey's Bay矿床矿石的硫同位素δ^34 S值通常落入公认的地幔硫同位素组成范围(0±2‰)内，而对其元古宙变质沉积围岩进行的详细研究结果显示δ^34 S的平均值也在此范围。
