E-mail地址中的符号@是什么意思

  That little "a" with a circle curling around it that is found in email addresses is  most commonly referred to as the "at" symbol.
  小写字母a外加个圆圈，这一标记常出如今email（电子邮件）地点中，通常是作为"at"(在)的标志。
  Surprisingly though, there is no official, universal name for this sign. There are dozens of strange terms to describe the @ symbol.
  但是令人感触惊异的是，这一标志居然没有官方的，通用的称号。有几十个稀罕的术语用来描绘@这一标记。
  Before it became the standard symbol for electronic mail, the @ symbol was used to represent the cost or weight of something. For instance, if you purchased 6 apples, you might write it as 6 apples @ $1.10 each.
  @这一标记在成为电子邮件的标准标记之前，曾被用来表示物品的单价或质量。例如，你买6只苹果。就可以写成"六只苹果，每只@$1.10，表示每只苹果1.10美元。
  With the introduction of e-mail came the popularity of the @ symbol. The @ symbol or the "at sign" separates a person's online user name from his mail server address. For instance, joe@uselessknowledge.com. Its widespread use on the Internet made it necessary to put this symbol on keyboards in other countries that have never seen or used the symbol before. As a result, there is really no official name for this symbol.
  随着电子邮件的利用，@这一标记越来越普及了。标记@或'at'标志将上彀用户的姓名与其邮件的服务器地点离开。例如：joe@uselessknowledge.com。 这一标记在因特网上的广泛利用使得很多以前从未见过或利用过它的国家必须在它们的电脑键盘上加上这一标记键，效果形成这一标记并没有真正的官方称号。
  The actual origin of the @ symbol remains an enigma.
  @标记简直切劈头仍然是谜。
  History tells us that the @ symbol stemmed from the tired hands of the medieval monks. During the Middle Ages before the invention of printing presses, every letter of a word had to be painstakingly transcribed by hand for each copy of a published book. The monks that performed these long, tedious copying duties looked for ways to reduce the number of individual strokes per word for common words. Although the word "at" is quite short to begin with, it was a common enough word in texts and documents that medieval monks thought it would be quicker and easier to shorten the word "at" even more. As a result, the monks looped the "t" around the "a" and created it into a circle-eliminating two strokes of the pen.
  汗青告诉我们，@这一标记劈头于中世纪僧侣委顿的双手。中世纪时印刷机尚未创造，要出书一本书，每一个单词的每一个字母都得用手工辛苦的刻出来。从事这项长时间辛苦誊录描画的僧侣们就开始探求减少每一个常用字笔画数的方法。固然"at"这一单词开始写起来很短，但它在文本和文件中频繁呈现。中世纪的僧侣们就想到要是能进一步简化它，就可以写起来更快更容易。效果，僧侣们就在a四周画了一个圈，从而免却了字母"t"的两个笔划
