During the study of the subject, I have an all-around understanding about the theory and application of Data Mining through reading bookmaking and papers in this field.Based on the research on algorithms, we realized one example following the workflow of Data Mining, which helps us understand the application of the technology.KEYWORDS: data mining , association rule , apriori algorithm

在课题的研究过程中，我通过阅读大量国内外著作、论文，对数据挖掘技术的理论和应用有了一个较为全面的了解，在理论上对关联规则的挖掘算法进行了深入的研究，对于数据挖掘的应用通过实现具体的实例进行研究，并且对挖掘结果进行评价，从而对数据挖掘的应用步骤有了更加深刻的理解。

At the same time, check sum is sent and communication protocol is established to keep error data out and multi-period measuring method is taken to improve measuring precision. Affective anti-jamming measures are given after all-sided analysis on potential interference.

在软件上，为提高系统的抗干扰性能，参数的检测采用了数字滤波算法；为防止通信中误码的产生，采用了发送校验和的方式，制定了与上位机的通信协议，同时为提高测量的精度，在测量时采用了多周期测量方法。

A curvature based method for controlling iteration step is further proposed by projecting the given point onto the curvature circle of the normal transversal at the initial point.

仿真结果表明，该算法具有良好的收敛性、鲁棒性以及精确性。正交投影的概念最早出现在文献[1]中。所谓正交，就是在曲面上找到一点，使得该点与空间某一给定点的连线与曲面在该点处的切平面是垂直的。

The algorithm is applied on TMS320DM6437 DSP, and the experimental results show that for a 768 pixels ×494 pixels image, the correction time is 0.036 s. The correction error is within 0.31 pixel and the edge information loss and inanition are effectively avoided.

将该算法在TMS320DM6437DSP上实现，实验结果表明，校正一幅像素为768×494的图像所用的时间为0.036s，畸变校正的误差在0.31个像素以内，有效地避免了边缘信息丢失、空洞及灰度失真现象。

In high frequency area of image, most general demosaicing algorithms have no way to reproduce true color if object width can only have 1～2 pels on CCD, and put up the color pieces having nothing to do with object content, that these color pieces call as colored moire.

在画面高频区，如果物体宽度在CCD上只有1～2个象素，那么就无法通过通常的插值算法重现其真实色彩，而表现出与物体内容无关的彩色块，这些有规律的彩色块就是彩色摩尔纹。

First, a features-preserving filtering algorithm for point set surface and surface attributes is developed,which is based on robust statistics.

首先是把鲁棒统计理论应用在了对点采样曲面保护特征的滤波中，并扩展该算法到定义在曲面上的函数的滤波中。

Google allows AdSense ads on scrapper sites Google is in favor of using algorithms as far as possible to weed out the trash, and to their credit they've done a lot over at Blogspot to reduce the splog-effect.

- 允许广告在垃圾站上显示目前Google已经利用算法尽量杜绝垃圾站上显示广告，并且Google已经在Blogspot上减少了垃圾站的效应。

In neural networks learning, the Sigmoid function is improved and the stability conditions of backpropagation algorithm is analyzed theoretically.

在神经网络学习中，改进了前向神经网络中Sigmoid作用函数表达式，并在理论上分析了反向传播修正权值的迭代算法稳定收敛的充分条件。

Third, The author analyzed the shimming method of the existing magnet system and programmed it. Because the base field homogeneity of the open magnet is worse and only passive shimming is available, it is necessary to study more effective shimming algorithm. The ordinary shimming method is based on the disintegration of the magnetic field using spherical harmonics. It is so tedious that involved in large scaled non-linear equations.

再次，详细分析了现有磁体系统的匀场方法，并通过编程运算，发现在开放型磁体这一特殊情况下，由于基场均匀度差和只能使用水磁材料垫补进行匀场等原因，基于对磁场分布用球谐函数分解并消去球谐函数高次项的常规匀场方法在实现上相当繁琐，牵涉到大型非线性方程组的求解，所以必须采用更有效的匀场算法。

Concrete algorithm is firstly recognizing 2D feature obtained from geometric entities, then on the instruction of the shape analysis combining with the projective rulers of mechanical drawing, matching three 2D view features, creating 3D basic model, forming a operation list, finically finished 3D reconstruction.

在重建算法上，利用提取的几何实体进行二维视图特征的识别，在形体分析法的指导下，结合制图中的投影原则匹配三维基本形体，最后按照基本体素的运算序列经过复杂的布尔运算完成重建。
