The discovery is of great archaeological value.

这一发现有很大的考古学意义。

Based on the former researches, according to the resources collected, this dissertation discussed the topic archaeologically and historically, by identifying each coins, and analysing the significance of these coins to the economical and cultural conmmunication between the west and the east during the 4th– 8th century.

总的说来，本文在前人研究的基础上，通过对中国发现的拜占廷金币及其仿制品的辨析，并根据现有的资料，结合4-8世纪中西经济文化交流的内涵与影响，对金币所涉之历史问题做出分析论证。

The main method of reinforcement pier is use different materials in the external of damaged pier, but in most of case, the damaged pier cant be repaired in time, so in this paper, we can solute such questions through architectonics so that the bridge pier capacity can keep from loss largely.

现有的加固方法主要是利用不同的材料在外部对损伤的桥墩进行加固，但是在很多情况下，桥墩不能够及时进行加固处理，所以本文通过构造性的设计方案，来解决在不能及时加固情况下，桥墩承载力不至于有较大的损失。

You can also zip up some existing file into an archive that is created in a memory buffer.

您还可以压缩成一个是在内存缓冲区创建归档某些现有的文件。

And here is one pattern from the archive, just to show what you'll find there.

而这就是一种模式，从存档，只是为了显示什么，你会发现有。

Company employees 500 people, covers an area of 50,000 square meters.

According to the non-classical receptive field of biology vision nerve cell, the paper presents the arithmetic operators of Orientation Difference of Gaussians with the help of the present theories of computer vision.

根据生物视觉神经细胞非经典感受野的特点，结合目前计算机视觉现有的理论和方法，提出了具有方向性的高斯差算子(Orientation Difference of Gaussians，ODOG)。

On the basis of OCM, segmentation based on curvature radium is presented in the paper, in which curvature radium is calculated using parametric-surface fitting, and detecting edge points is realized from orthogonal direction, which ensure the integrality of edge points. Since the data is organized by cross-line in OCM, a new arithmetic, Double-direction Angle Difference arithmetic, is brought forward, which can pick up edge points more quickly.

物体的表面一般由多个曲面相交组成，要建立完整的几何模型，需要对测量数据进行区域分割——区分不同曲面的数据，现有的区域分割大多是对单视图的图像式测量数据进行的，但完整的CAD模型需要联合多个视图产生，本文在上面提出的三维正交模型的基础上，提出了三种区域分割方法：第一种方法是基于曲率半径的数据分区方法，通过二次参数曲面拟合计算局部曲率半径，从正交的多个方向进行检测，保证了边点提取的完整性。

Compared to exist detection methods, the arithmetic's operation is simpler, and need not complex coordinate change, which are more practical.

与现有检测方法相比，该算法具有运算量小，不需进行复杂的坐标变换等特点，具有很大的工程实用性。
