这可以保证特征集与图像之间的一一映射关系，避免伪造攻击。
That can ensure the one to one mapping relationship between the feature set and the image, and avoid the counterfeit attack.
我要提醒你们的是，我们看了很多算法，我的目标之一是让你们开始，意识到算法们的特性，并且能够一一映射到特定的分类中。
And I'll remind you, we saw a set of algorithms and part of my goal was to get you to begin to recognize characteristics of algorithms that map into a particular class.
利用该平面坐标网二叉树，把平面中的网格点一一映射到一个整数集合上，从而可以把平面中的任意点近似地映射为一个整数，而且可以任意精确，对任意平面图形图象的处理、储存和传输起着极其重要的作用。
The net points of a plane can be mapped onto a set of integers in a one to one way based on the tree, so can any point of a plane be approximately mapped onto an integer with arbitrary accuracy.
请注意，本文将不深入讨论对象-关系映射这一一般性的主题。
Please note that this article will not go into the general topic of object-relational mapping.
映射基本上是一一对应的；除了有必要对嵌套标记的量化和交替使用中介体之外（中介体名称用前导下划线标出来）。
The mapping is basically one-to-one; except it is necessary to use intermediaries for quantification and alternation of nested tags (intermediary names are marked by a leading underscore).
惟一一种能在映射规范内被积极使用的Business Glossary内容是业务术语。
The only type of Business Glossary content that can be actively leveraged in a mapping specification is business terms.
Unicode通过提供一个的单一一致的“字符至数字”的映射模式，能够表示世界上每一个字符；unicode使应用程序能够提供多语种支持。
Unicode can represent every character in the world by providing a single consistent character-to-number mapping schema; Unicode enables applications to provide multilingual support.
Order类中现在只剩一一个简单类型，Date，我们不会再花费时间，现在你可以关闭Order类的映射文件。
The only other mapping in the Order class is a simple property mapping for the Date property. We will not spend time on that here, so you can close the Order mapping file.
