The main results in this paper as follows: First, a prototype of a shape-based image database retrieval system is completed, it can receive the query mode both by giving an example image and by sketching the desired object on the screen, Second, five shape-based image retrieval methods are realized; Third, an algorithm based on triangulation for shape-based image retrieval is brought forward. In this algorithm, firstly, the edge of the original image is followed and the candidate corners in the original image are detected. Then the counterpoints of the candidate corners in the result of edge follow are found, and the boundary corners whose counterpoints have been found are queued in the order of their counterpoints in edge follow. After these steps, the boundary corners are triangulated and triangles are obtained which can show the true shape of the original image. Finally, shape feature is obtained by calculating the angle histogram of the triangles.

同时本文中主要完成了以下三方面的工作：完成了一个基于形状特征的图象检索的原型系统，可实现例子图象或徒手绘草图两种查询方式；实现了五种利用形状特征进行图象检索的具体方法，并对其进行了分析比较；并且在继承将三角剖分引入形状检索的思想基础上提出了利用三角剖分进行形状检索的一种新算法：先对原图象进行边界跟踪和角点检测；然后寻找初始角点在边界跟踪中的对应点，并对找到对应点的角点按其对应点在边界跟踪中的顺序进行排序；再对排序后的角点进行德洛内三角剖分，得到能表示目标真实形状的三角形序列；最后计算三角形序列的角度直方图作为形状特征，并进行相似性匹配。

Remember, dog-ears commonly arise from two situations: the angle of the ellipse is too obtuse,or the length discrepancy between the two limbs is too great to allow for a "stealing" stitch.

三角形尖端的缝合法：先从一侧皮肤进针，从创缘内出针后再横行穿过三角形皮瓣尖端的真皮下或皮下，然后由对侧创缘相应厚度进针，穿出皮肤，轻轻拉拢结扎，使三角瓣尖端与两边皮肤对合好。

The main idea of this algorithm is as following: firstly, the rectangle is classified by the value and position of its vertices; secondly, the rectangle is divided into some mangles through classification; thirdly, trace and render contour on each triangle obtained above.

算法基本思想是：先对矩形网格4个顶点值按照其大小和相互位置关系分类，然后把矩形网格划分为若干个三角形网格，最后在三角形网格内完成等值线的追踪和填充。

在里面0.9-1.6厘米，被微柔毛的两面或无毛的1 厘米萼片狭三角形，4-11毫米花冠黄，管的Pedicel；裂片具红色基部斑点在里面，卵形，令10厘米的是，突然缩小进下垂有尾给毫米宽；副花冠裂片10，黄绿色，锥形的三角形的或，0.9-3毫米花药包括，给子房无毛0.6毫米有尾的药隔。

The isosceles low triangle rod of the device shows as the shape of barrette file, pinching the rod in hand is easy for locating the temperature sensing liquid in the hole quickly, when observing the temperature value, the declining and vertical angle of the temperature character is much flatter than that of the high triangle rod, without extra effort of the eyesight.

其等腰低三角形棒体，呈扁三角形状，捏在手指间便于快速的寻找到孔内的感温液体，观测温度值时，温度数字体的斜立度比高三角形棒体平了许多，不费眼力。

Our Middle Class consists of Equilateral or Equal-Sided Triangles.

我们的中产阶级由等边三角形、也称各边相等的三角形组成。

For kindred reasons, geometrical propositions, that, for instance, in a triangle two sides together are greater than the third, can never be derived from the general concepts of line and triangle, but only from intuition, and this indeed a priori, with apodeictic certainty.

就连所有几何学原理也是如此，例如在一个三角形中两边之和大於第三边，就绝不是从关於线和三角形的普遍概念中，而是从直观中，并且是先天地以无可争辩的确定性引伸出来的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
