点过程

By using the meshless method, a numerical ocean engineering basin was established to simulate irregular waves propagated in shallow water. Locating the source points outside the computational domain, the problem of water wave propagation was solved by collocation of only a few boundary points instead of meshes.

采用基于配点和径向基函数的无网格数值模拟方法，建立数值海洋工程水池，将源点布置在模拟波浪场之外，沿边界布置配点而不是划分网格；对深水不规则波经斜坡过渡后在均匀水深浅水域中传播的过程进行无网格数值模拟和波谱的迭代修正。

Due to discretization error of image points and inevitable location shifts embedded in feature extraction processes, the parameters of a line determined by two feature points must possess some uncertainties.

由于图像特征点的离散误差和特征点提取过程中的位移现象，使得由二图像点所确定的直线的参数随之产生某种不确定性。

The whole process is discontinous and can be thought of as finding the grid points on a specified region of the X-Y plane (Think of marking all integer interception points on a paper). Convert each grid point's X and Y coordinate to exponential values (like 2^x, 2^y) then we can use them as value of cost and gamme for cross validation.

这个过程是不连续的成长，所以可以想成我们在一个 X-Y 平面上指定的范围内找一群格子点(grid，如果你不太明白，想成方格纸或我们把平面上所有整数交点都打个点，就是那样)，每个格子点的 X 跟 Y 经过换算(如 2^x， 2^y)就拿去当 cost 跟 gamma 的值来 cross validation。

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

Firstly got the sequence of the contour points with one pixel width of the image to be assembled.

首先求出待匹配图像单像素宽的轮廓曲线上像素点的坐标序列，然后利用轮廓上各点和与其相差六个点的像素点之间的位置关系及行列坐标差的平方代数和对轮廓进行表示，得到两轮廓曲线的表示序列后；接着采用寻找两轮廓表示序列的最长公共子序列的方法进行匹配，并在匹配过程中引入了"断点续配"的概念，有效提高了算法的容错性。

The conversions of ice temperature and ice velocity occur from bridge to trough of terrain on the eastern Nyainqentanglha Range. The ice temperature at bridge is lower. The ice at bridge starts to move due to the larger gravitational driving stress. During the course from bridge to trough of terrain, basal ice temperature rises because of the friction. While reaching the pressure melting point of ice, basal decollement occurs, and higher velocities can still be produced at trough.

而位于念青唐古拉山东部地区的冰川，冰温和冰速从地形脊到地形槽处发生了较大的转化过程，在地形脊处冰温较低，受重力加速度的影响，冰川开始产生滑动，从地形脊到地形槽滑动的过程中，其底部受摩擦加热的影响，底部冰温升高，达到融化点，底部产生变形，到地形槽处仍会产生较大速度的滑动，因此冰川的运动从地形脊到地形槽处发生了转化，即地形脊处的滑动属动力过程引起的滑动，而地形槽处的滑动属热力过程产生的滑动。

The influence of Pb-contamination on microstructure and shear strength of SnAg/Cu and SnSb/Cu solder joints prepared by SMT were studied by mixing eutectic SnPb solder paste into leadfree solder pastes.

Firstly, because the triangle constrained matching propagation begins with the initial corresponding triangulations formed by a few seed points in the stereo pairs, this dissertation studies the affects of different numbers and different distributions of seed points on the image matching results through experimental analysis, and proposes a seed point selection strategy for different image texture conditions, an automatic selection algorithm is also designed that gives good distribution quality for a defined number of seed points.
