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。

Allowed the date that" year" indulge in atrocities on the whole, the common people treat this terrible night as to close to come then very, call" year end", and figured out a the whole set to celebrate New Year's Eve the way of the pass:Each time to this evening, each per families work well the supper in advance, turn off the clean cooking stove, then chase a fastening with all stockade of chicken, the house hospital in front and back the doors all seal, hiding to eat" New Year's Eve dinner" in the house, because of this dinner have fierce 吉 don't 卜 of meaning, so buy very flourishing, in addition to wanting that the whole family the old and the young rounds together to have a meal to mean in peace and harmony and reunitedly, return the beard at have a meal to provide the worship of ancestors before and first first, the spirit of the imprecation ancestry protect, spending this night safe and sound, after eating the supper, who all dare not the sleeping, pushing to sit together to talk away to encourage.

到了宋代，人们便开始在桃木板上写对联，一则不失桃木镇邪的意义，二则表达自己美好心愿，三则装饰门户，以求美观。又在象征喜气吉祥的红纸上写对联，新春之际贴在门窗两边，用以表达人们祈求来年福运的美好心愿。为了祈求一家的福寿康宁，一些地方的人们还保留着贴门神的习惯。据说，大门上贴上两位门神，一切妖魔鬼怪都会望而生畏。在民间，门神是正气和武力的象征，古人认为，相貌出奇的人往往具有神奇的禀性和不凡的本领。他们心地正直善良，捉鬼擒魔是他们的天性和责任，人们所仰慕的捉鬼天师钟馗，即是此种奇形怪相。所以民间的门神永远都怒目圆睁，相貌狰狞，手里拿着各种传统的武器，随时准备同敢于上门来的鬼魅战斗。

The issues of present seismic wavelet frequency caused by different concepts, such as apparent frequency, dominant frequency, peak frequency and centroid frequency, etc., which are defined by different methods, and understanding deviation, definition of seismic wavelet frequency for time and frequency domain are concluded and summarized. On this basis, three kinds of seismic wavelets in common use such as Ricker and Zinc wavelets as well as sine wavelet with exponential attenuation characteristics are analyzed and a conclude is achieved that apparent frequency and dominant frequency are consistent in essence, but peak frequency and centroid frequency as well as apparent frequency or dominant frequency are not completely consistent with different seismic wavelets. For actual seismic data, peak frequency can approximately be used as dominant frequency, but it is not suitable when seismic wavelet is known for it can give out any wrong knowledge and results.

针对目前地震子波频率由于定义方式出现的各种概念（视频率、主频、峰值频率、中心频率等）以及理解上出现的偏差等问题，首先从时间域定义和频率域定义2个方面进行了归纳和总结，并在此基础上对3种常用地震子波（Ricker子波，Zinc子波，正弦指数衰减子波）进行了分析和研究，得出视频率与主频概念一致，但不同地震子波的峰值频率、中心频率和视频率之间并不完全一致的结论；而对于实际地震资料，将峰值频率近似看作地震子波的主频是可以的，但在地震子波已知的情形下这样做是不恰当的，甚至可能会得出错误的结论和认识。
