Another display shows the 1914 Yuan Shih Kai Dollar (Y329 type) with three different edges – with ordinary reeding, with a "Greek border" or alternating "T" design on the edge, and with a sort of "herring bone" design edge, in which curved, raised bars alternate with raised boxes.

另一个被展出来民国三年袁世凯头像壹圆（Y329 type，不知是啥，可能是PCGS的标识吧）也有三种不同的齿边，一种也是普通的刻槽直齿边，一种呢，是被称作"希腊边"的样式，也就是字母"T"上下交叉排列设计的的一种齿边样式②，第三种齿边样式有点类似於鲱鱼的骨头，末端呈弯曲的样子，凸起阴刻的线条连接著这些凸起末端弯曲的像隔栅线③。

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

According to disadvantage of AS that the speed low of convergentiss and easily entering the stagnation,improving the AS in some aspect by the way that importing pheromone windows that the value of pheromone cannot exceed the window,only deposit the pheromone on the edge that belongs to the iteration shortest solution path,releasing additional pheromone to the edge belongs to the so-far shortest solution path,judging the situation of convergent and to reinitialize pheromone,optimizing the solutions by local search procedure at the end of every iteration,modifying the transition probability by add some problem specific parameters and so on.

本文主要运用蚁群优化算法(Ant Colony Optimization，ACO)来求解VRP。针对蚁群算法收敛性比较差，易于停滞的缺陷，通过使用信息素窗口限制、信息素的最大最小值，只更新信息素迭代中最好解，增加了精英的蚂蚁，信息素重新初始化之前先判断出汇聚情况，在每次迭代过程中加入局部的搜索进行优化，在对蚁群算法进行了优化时考虑选择概率当中加入与问题的相关参数等措施，从而使蚁群算法的收敛性得到大大提高，避免了算法的停滞现象。

This paper introduces a method of edge detection. By comparison with topography, it is found that the character of edge of image shows the same valley's character as relief map.

利用图象边缘轮廓呈现的一种沟壑性质，开发了一种通过求象素亮度的极值来进行边缘检测的方法。

Given a graph G representing a network topology, and a collection T ={(s1 , t1 )...} of pairs of vertices in G representing connection request, the maximum edge-disjoint paths problem is an NP-hard problem that consists in determining the maximum number of pairs inT that can be routed in G by mutually edge-disjoint si ti paths.

由于图G代表的网络拓扑，并且收藏笔=( S1及T1期……的顶点G大代表连接请求，最大边不相交的路径问题是一个NP-hard问题，它包括确定最多偶笔可以改为G大相互边相交硅钛路径。

Resonant laser ablation is a two-step process, occurring within a pulse of a tunable laser, in which the leading edge of the laser pulse ablates the surface of the solid sample to produce neutral atoms or molecules that are then resonantly ionized by the trailing edge of the same pulse.

共振激光烧蚀技术是指发生在同一激光脉冲时间内的两步过程，它是指用波长可调谐的染料激光取代固定波长输出的激光，并调谐激光输出波长实现所研究原子或分子电子态之间的共振跃迁，激光单次脉冲的前沿对样品进行烧蚀，烧蚀的物质在激光光束内形成粒子气团，同一次激光脉冲的后沿实现对气相原子或分子的共振电离。
