The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors. We design and implement an SOA(Service-Oriented Architecture)-based UTDD(urban traffic data mining development) with high expansibility and performance, which implement unified management and call of the data-mining application though defining a XML-based description of data-mining process and a common interface to call data-mining process, finally we build traffic flow prediction application model on UTDD.

根据交通流量数据分布的特征，提出基于k-means的二次聚类方法，对交通流量在流量大小和时间上进行模式划分，进而对各个交通流模式进行基于BP神经网络的描述和预测，从而提高模型对流量预测的精度； 2）根据流量/时间占有率倒&V&字形曲线分布模型，提出基于最小二乘法的三次多项式曲线拟合和统计方法的异常检测方法，实际应用表明该方法能够有效识别异常数据，然后根据移动平均算法对异常数据进行修正； 3）基于序列相关性分析，分别对预测方向的交通流量数据序列、上游路口相关序列以及预测路口其它各个方向上的交通流量序列进行分析，选择相似性流量序列，作为辅助序列提供其他没有检测器路口的流量估计； 4）设计和实现了基于SOA（Service-Oriented Achitecture）的高性能、可扩展的智能交通数据挖掘系统UTDD，该系统通过定义基于XML的数据挖掘过程描述和通用的过程模型接口，实现数据挖掘应用的统一管理和调用，最后在UTDD上建立了基于路口流量预测的应用模型。

Although the standard k-ε turbulence model has been proved to be a model adapting a large range of conditions, it does not fit in with the cases where the normal Reynold stress of fluid is of great importance. As generally known, these cases include at least some cases where recirculation or secondary flow takes place.

在目前多数研究中，采用的湍流模型为标准k-ε湍流模型，这种模型虽已被证实是一种适应范围较大的模型，但其并不适用于流体中雷诺正应力占重要作用的情况，目前所知，具有回流区和二次流的一些流动便属于此种情况。

Our model is obviously superior to Rinker'smodel. because Rinker's model potential is a combination of Thomas-Fermi-Dirac potential and Hartree-Fock-Slater potential for the isolated ion.

我们的模型明显优越于Rinker的模型在于： Rinker的模型采用的是Thomas-Fermi-Dirac势和自由原子的Hartree-Fock-Slater势的迭加形式，而我们的模型中除离子的结构因子外，电子散射势、化学势及电离度等量都是通过自洽迭代方法计算的。
