at什么意思？

AT什么意思？~

AT的含义很多，现列举如下：
1、AT 代表自动变速器(automatic transmission）自动变速器，又称自动档。自动变速器由 液力变扭器、行星齿轮变速器、控制机构组成。能根据路面状况自动变速变矩，驾驶者可以全神贯地注视路面交通而不会被换档搞得手忙脚乱。

2、AT：英文名字Anastoms，中文“奥斯通”，简称“AT”，是基于以太坊公有链，采用以太坊的智能合约发行的一款数字资产。AT是易解通在能够解决全球债事关系的基础上，嵌入区块链技术，发行的全球首个公开发行的区块链债事数字资产，紧密运用于易解通能够解决全球债事关系的1.0阶段，应用于全球债事的登记、转让、流通、交易、结算，具有极高的价值。
3、AT全称辅助技术（Assistive Technologies），是扮演用户代理角色的硬件或者软件，又或者是满足残疾人使用那些主流的用户代理的辅助接口。辅助技术提供的服务包括替代演示（如合成语音或放大内容），替代输入方法（例如，语音识别），附加的导航或定位机制，内容转换等。
4、AT=assistant tank，指的是副坦，二坦。副坦角色半数情况下和主坦一样，主要来当肉盾，但是有时候因为不同BOSS的战术需要，需要一个能抗的职业去做一些特殊的事情，并不一定需要很高的技巧，但也是战斗胜利的必须。
5、AT(Application Terminal）彩信上行。意为应用程序做为终端的消息递送，区别与短消息的MO(Message Original），相应的彩信下行称为AO(Application Original），短信上行称为MT(Message Terminal）。

网络语AT是指@符号，电子邮件地址中代表“某用户”在“某服务器”（aaa@bbb.com）。而在社交网络中通常用“@+昵称”来通知用户。
@起源于美国电脑工程师雷·汤林森将@符号作为电子邮件的表现格式，随着网络普及，@符号也用于多种场合。
在中国，@的读音出现了多个读法，比较流行的有两种：一是“圈a”，二是“花a”。实际上，在电子邮箱的表示形式中，@有着at的含义，即“某用户”在“某服务器”。由此，应该根据此处@的具体含义，将其读作at的读音“艾特”。

扩展资料：
@艾特的起源：
1971年，美国电脑工程师雷·汤林森奉命寻找一种电子邮箱地址的表现格式，他首先编写了一个小程序，通过程序可以将文件传输到另一台电脑上。
汤林森要确保邮件抵达正确的电脑。这时他需要一个标识，以此把个人的名字同他所用的主机分开。汤姆林森一眼就选中了@这个特殊的字符，这个在人名之中绝对不会出现的符号。
这个符号必须简短，因为简洁是最重要的。而@是键盘上唯一的前置标识。这样一来，既可以简洁明了地传递某人在某地的信息，又避免了电脑处理大量信息时产生混淆，第一数字地址传递tomlinson@bbntenxa就应运而生了。
